Signal protection is one of its most useful qualities. The double-shielded design is intended to reduce electromagnetic interference, noise, crosstalk, and hiss, while 99.9% oxygen-free conductors are designed to support signal purity. Metal connector shells add mechanical strength around the termination points, where repeated plugging and cable movement often place the greatest stress.
The product is also built for flexing. Its nylon-braided exterior is stated to withstand more than 15,000 bending cycles without cracking or breaking. Although that claim cannot be independently verified from the listing alone, the described construction suggests a more robust cable than a basic molded adapter, which is valuable if the splitter will remain permanently installed.
This is a good choice for a receiver or amplifier with one male RCA output that must feed two female-input devices. It is less suitable if your system needs two male plugs to enter a single female socket, because that requires a different connector direction. For a compact, protected, general-purpose male-to-female splitter, this is the most balanced recommendation in the group.
Clean Signal for Compact Audio Setups
Double shielding and oxygen-free conductors make the adapter a sensible option when several devices sit near computers, televisions, power cables, or other potential interference sources. The short cable also reduces excess slack behind an entertainment center.
Built for Repeated Daily Handling
Metal connector shells and a nylon-braided jacket add durability in installations that may be unplugged, moved, or routed around furniture. That makes the adapter practical for temporary setups as well as semi-permanent connections.

2. RCA Splitter Two Pack – Best Multipack Male-to-Female Adapter
RCA Splitter Two Pack
Male-to-female RCA split
Two adapters included
Dual shielding
Gold-plated connector contacts
This two-pack provides two one-male-to-two-female RCA split adapters and carries a 4.7 rating. It is a practical selection for users who need a spare adapter, want to connect more than one source arrangement, or prefer to keep an identical unit in a second equipment location.
Pros
- Useful two-cable quantity
- Soft flexible PVC jacket
- Copper and foil shielding
- Broad device compatibility
- Clear directional configuration
Cons
- Additional RCA cable may be required
- Short adapter length is not specified

Its soft PVC cable and antioxidant, thickened gold-plated connectors are intended to withstand regular use while resisting corrosion. The shielding combines copper braid with aluminum foil, a common approach to reducing electromagnetic and radio-frequency interference. That construction supports the stated use cases across subwoofers, home theaters, HDTVs, gaming consoles, and conventional Hi-Fi equipment.
One important point is that this is an adapter, not a complete run of RCA cable. The listing specifically notes that an additional RCA cable is needed. Buyers should therefore verify that their source device has an available male plug and that the destination equipment has female RCA inputs, or plan to add the appropriate interconnect cables.
This multipack is best for buyers who prioritize flexibility and redundancy. The two adapters are particularly useful if one setup requires splitting a left and right channel pair or if you want to keep a replacement nearby. Choose it over a single-cable option when the included quantity and connector protection better match your installation.
A Spare Solves Setup Snags
Having two matching splitters can prevent a common installation problem: discovering that a second component needs the same one-to-two connection. It is also useful for car audio, a second room, or a temporarily disconnected system.
Shielding for Everyday Equipment
The combined braided copper and aluminum foil layers help protect the audio signal from nearby electronics. The flexible PVC jacket makes the short adapter easier to position behind equipment than a stiff cable.

3. Arklove RCA Splitter – Best Premium Shielded Two-Pack
Arklove RCA Splitter
Male-to-female RCA split
Two one-foot cables
4N oxygen-free copper
24K gold-plated connectors
The Arklove splitter is a two-pack of shielded one-foot RCA cables, each with one male input and two female outputs. Its 4.6 rating places it among the well-regarded options, while the use of 4N oxygen-free copper, 24K gold-plated pure copper plugs, and a shielded construction distinguishes it from simpler adapters.
Pros
- Two shielded cables included
- Premium gold-plated contacts
- One-foot routing-friendly length
- Works with two amplifier sets
- Supports separate amplifier operation
Cons
- Longer than compact adapter models
- Two female outputs still require cables
We may earn a commission when you buy through this link, at no additional cost to you.
The product is explicitly designed for a source that feeds two amplifier sets. The listing states that both amplifiers can operate at the same time or separately, offering a direct explanation for the Y configuration. This makes the cable relevant to multi-zone or multi-amplifier audio arrangements, although the connected equipment should be checked for compatible output and grounding arrangements.
Gold plating provides corrosion resistance and a durable contact surface, while the oxygen-free copper conductor is intended to support stable signal transfer. The one-foot length offers more placement flexibility than a stubby adapter, making it easier to reach around a receiver, amplifier, or powered subwoofer without a conspicuous expanse of loose cable.
This is the premium pick for users who value connector finish, two included cables, and a little more routing length. Its main limitation is that it still follows the one-male-to-two-female format, so it will not solve a connection requiring two male ends or one female end. For compatible dual-amplifier setups, its construction and included quantity are particularly appealing.
One-to-Two Amplifier Flexibility
This splitter is tailored to a source feeding two amplifier sets, with the option to use those connections together or separately. That makes it more specialized than a generic short adapter while still serving conventional RCA audio paths.
Premium Contact and Conductor Materials
The stated 4N oxygen-free copper and 24K gold-plated plugs focus on conductivity and corrosion resistance. Those details can be particularly attractive to buyers maintaining a permanently installed home audio or amplifier network.

4. RCA Splitter Two Pack – Best Female-to-Male Two-Pack Option
RCA Splitter Two Pack
Female-to-male RCA split
Two adapters included
Braided copper shielding
Requires existing RCA cable
This adapter reverses the common split arrangement by offering one female end and two male ends. It carries a 4.6 rating and includes two matching cables. That direction is useful when a device has a female RCA input and needs to receive connections from two male-plug sources or an existing male-ended cable.
Pros
- Correct direction for female inputs
- Two matching adapters included
- Dual shielding reduces interference
- No drivers or software required
- Gold-plated connector construction
Cons
- Existing RCA cable is required
- Not intended for female outputs
We may earn a commission when you buy through this link, at no additional cost to you.
Dual shielding combines braided copper with aluminum Mylar to reduce impedance and help maintain stable stereo surround sound. The connectors are described as antioxidant and gold-plated, combining a corrosion-resistant contact surface with a durable PVC cable body. The product also emphasizes simple plug-and-play operation without additional software or drivers.
As with many Y adapters, direction should be confirmed before ordering. A one-female-to-two-male cable can visually resemble a one-male-to-two-female product because the branches can be rotated, so read the title and connector descriptions carefully. Incorrectly matching the direction can leave a source or destination unable to connect as intended.
This two-pack is best for a subwoofer, amplifier, receiver, or other device with a female input that must be connected through male-ended leads. It is less useful for users who need to split one already-male output into two female inputs. For the correct female-to-male installation, however, it offers dependable shielding and the convenience of a spare.
Correct Direction for Female Inputs
The one-female-to-two-male layout is especially relevant to equipment that presents a recessed female RCA socket. It lets two male-ended sources or cables meet at that input without modifying the equipment.
Stable Shielded Connections
Braided copper and aluminum Mylar shielding are designed to limit interference and support consistent audio. The plug-and-play design also avoids unnecessary configuration once the connector direction has been verified.

We may earn a commission when you buy through this link, at no additional cost to you.
The cables use a 99.9% oxygen-free conductor intended to support signal clarity and minimize distortion and interference. Foil-wrap shielding provides a barrier against electromagnetic interference, while the split-tip male connector is designed to create a secure fit during signal transmission. A secure connection matters in a vehicle, where cables and plugs may be exposed to vibration, temperature changes, and cramped mounting areas.
Its most notable advantage is the included quantity. Two adapters allow the same connection pattern to serve separate areas or provide a backup when one adapter is being used. The one-foot length also gives enough reach to negotiate a back panel, under a seat, or behind a cabinet while remaining less cumbersome than a long extension.
This is a good recommendation for a car stereo installation or a home system that needs a compact splitter. The trade-off is that the product description specifically emphasizes foil shielding rather than the combined braid-and-foil approach used by several competitors. Buyers should also confirm that the visible blue connector matches any color-coding requirements, although RCA signal channels are normally identified by position and labels.
Useful for Mobile Audio Routing
The compact one-foot form and secure male plug are well suited to the limited space and vibration common in car installations. Its stated compatibility with car audio makes it a focused alternative to longer home-theater cables.
Signal Clarity with a Secure Fit
The oxygen-free conductor and foil shielding target stable, low-interference transmission. The split-tip male plug is designed to resist accidental disconnection during normal handling.

Six-foot cable length
Copper braid and foil shielding
24K gold-plated connectors
The six-foot FosPower RCA Y-Adapter has one common male plug and two male output plugs, with a 4.7 rating. Its unusual connector direction makes it appropriate for a device that accepts a female RCA input but needs to offer two male-ended connections through an adapter.
Pros
- Generous six-foot routing length
- Dual-layer shielding
- Gold-plated corrosion-resistant contacts
- Flexible PVC outer jacket
- Tin-plated copper core
Cons
- Male-to-male direction may not fit
- Longer than most compact splitters
We may earn a commission when you buy through this link, at no additional cost to you.
Construction is a central strength. The 24K gold-plated contacts are designed to resist corrosion and tarnish, while a tin-plated copper core is intended to support stable transmission and resist oxidation. A polyethylene foam dielectric is included to help minimize signal loss, and the PVC jacket balances flexibility with everyday protection.
Dual shielding adds another layer of protection. Copper braid and aluminum foil work together to reduce unwanted EMI and RFI interference, which is useful when the cable passes near power cables, receivers, or other electronics. The six-foot length is generous enough to connect components in different parts of a cabinet, entertainment center, or home-theater installation.
This is the better FosPower option when distance is the priority. Buyers should note that the adapter includes male plugs on both branches and the common end, so it does not serve as a one-male-to-two-female splitter. For a correctly matched female-input installation, its length, shielding, and connector finish make it a dependable long-run option.
Reach Across Separate Components
Six feet provides enough distance to bridge equipment positioned in different sections of a home-theater cabinet or entertainment center. It avoids the need for an additional extension when the source and destinations are not adjacent.
Layered Protection Against Interference
The copper braid and aluminum foil layers are intended to reduce EMI and RFI. Gold-plated contacts, a stable core, and a dielectric layer complement that shielding for a construction-focused cable.

7. FosPower Short Y-Adapter – Best Compact Male-to-Male Option
FosPower Short Y-Adapter
Male-to-male RCA split
Three-foot cable length
Dual-layer shielding
24K gold-plated connectors
The three-foot FosPower short Y-adapter has the same one-male-to-two-male configuration as the six-foot version but offers a more compact installation. Its 4.7 rating indicates strong customer reception, and the construction details remain focused on stable signal transmission, shielding, and durable connector contacts.
Pros
- Compact three-foot length
- More reach than a stub adapter
- Dual-layer interference protection
- Corrosion-resistant contacts
- Flexible PVC jacket
Cons
- One adapter only
- Requires compatible female inputs
We may earn a commission when you buy through this link, at no additional cost to you.
The cable combines copper braid with aluminum foil shielding to reduce electromagnetic and radio-frequency interference. Its 24K gold-plated connectors resist corrosion and tarnish, while the tin-plated copper core and polyethylene foam dielectric are intended to support signal stability and reduce loss. A flexible PVC jacket allows the cable to bend and route behind equipment more easily.
Three feet is a useful middle ground. It provides enough reach for a powered subwoofer, amplifier, or receiver positioned a short distance from the source, but it is less likely to create excess slack than a long cable. That makes it easier to bundle and conceal in a cabinet, on a shelf, or around a speaker stand.
This model is best when the equipment presents female RCA sockets and the installer needs two male-ended connections without a lengthy extension. Its limitation is that the connector direction is specialized, and only one adapter is included. If those conditions match your system, it offers a well-balanced mix of reach, protection, and compact routing.
A Practical Middle Length
Three feet gives a compact adapter enough flexibility to cross between nearby components while remaining easy to manage. It is often a better fit behind a media console than a full-length audio cable.
Same Core Construction, Less Cable
This shorter version retains gold-plated contacts, a protected copper core, dual shielding, and a flexible jacket. It gives buyers the same construction features as the longer option without as much excess cable.

8. RCA Y Cable – Best Extended Male-to-Male Connection
RCA Y Cable
Male-to-male RCA split
Fifteen-foot cable length
Pure copper conductors
Advanced dual shielding
The RCA Y Cable is the longest adapter in this guide, offering 15 feet of cable with a one-male-to-two-male configuration. Its 4.6 rating reflects a favorable response, and the extra reach makes it suited to home theaters, amplifiers, subwoofer enclosures, and Hi-Fi systems where source and destination equipment may be separated across a room or large cabinet.
Pros
- Long fifteen-foot reach
- One-piece metal internal pins
- Pure copper conductor construction
- Gold-plated connector contacts
- Includes reusable cable ties
Cons
- Long cable may be unnecessary
- Direction remains male-to-male
We may earn a commission when you buy through this link, at no additional cost to you.
Pure copper conductors are used to support stable signal transmission, while advanced dual shielding is designed to reduce EMI and RFI interference. The 24K gold-plated connectors offer corrosion resistance, and the listing highlights a one-piece metal internal pin intended to resist breakage. These are useful attributes for a long cable likely to be routed, bundled, or handled repeatedly.
The high-elasticity PVC jacket provides a softer grip and some flexibility during installation. Five reusable cable ties are included, which is a particularly useful detail because a long cable can be difficult to manage without proper bundling. Those ties can keep excess length grouped behind a television stand, cabinet, or desk.
The main trade-off is manageability. Fifteen feet is ideal when the signal path demands distance but excessive for a tightly grouped system. Buyers should also verify that their equipment supports a female-to-two-male connection and that a long passive cable is appropriate for the signal and devices involved. Where those conditions fit, it is a capable extended solution.
Distance Without a Separate Extension
The 15-foot length connects components that cannot be reached comfortably with a short adapter. It is useful for subwoofers placed away from a receiver or for installations where both branches need a substantial run.
Durable Pins and Cable Management
The one-piece metal internal pin is designed to better withstand repeated handling, while the included reusable ties help prevent tangles. Gold plating supports corrosion resistance and consistent contact over time.

Female-to-male RCA split
Four adapters included
Pure copper conductors
0.6-foot cable length
This four-pack of 0.6-foot RCA Y adapters has a 4.8 rating, tying for the highest rating among the featured products. Each adapter uses one female end and two male ends, making it suitable for dividing one mono source into two signals or combining stereo sources into a mono path, subject to the equipment's actual input and output design.
Pros
- Four matching adapters included
- Highest-rated multipack option
- Aluminum alloy connector shells
- Gold-plated plug contacts
- Broad home and car compatibility
Cons
- Short 0.6-foot branches
- Female-to-male direction only
We may earn a commission when you buy through this link, at no additional cost to you.
The cable core is described as pure copper, while foil shielding and a quality PVC jacket help reduce EMI and RFI interference. Aluminum alloy connector shells improve mechanical strength, and 24K gold-plated plugs are designed for durability, stability, and minimal signal loss. These details make the adapter appropriate for home theaters, amplifiers, televisions, DVD players, subwoofers, and car audio equipment.
The principal advantage is quantity. Four matching units support several installations, provide spares, or allow one adapter to remain in each of multiple systems. Their 0.6-foot length keeps them compact behind receivers and amplifiers, although it may be too short when the connected devices sit farther apart.
This is the strongest choice for buyers who want several female-to-male adapters at once, particularly if their devices have female RCA inputs. Direction and distance remain essential checks. If the equipment requires male-to-female splitting or longer branches, a different product in this guide will be a closer match.
One Purchase Covers Several Systems
Four included adapters make it easy to connect a home theater, amplifier, subwoofer setup, and car system, or to keep spares available. The matching construction also simplifies inventory when several identical signal paths are needed.
Protected, Durable Connector Design
Pure copper cores, foil shielding, aluminum alloy shells, and gold-plated contacts create a construction focused on stable signal transfer and resistance to everyday wear. These features complement the adapter's very short, installation-friendly length.

We may earn a commission when you buy through this link, at no additional cost to you.
Dual shielding protects against RF and EM interference, while gold-contact connectors are intended to support conductivity and durable connections. Secure-grip, color-coded connectors make it easier to identify left and right channels and handle the plugs consistently. The black exterior and familiar Y-adapter format suit a broad range of home audio arrangements.
The 12-inch length provides enough reach to move a connection around equipment or from a receiver toward a nearby powered subwoofer. It is a useful middle ground between extremely short adapters and long extension cables. The main limitation is that it is an adapter only: buyers need an appropriate male-ended RCA cable or a source that already presents the correct connection.
This is a sensible recommendation for a straightforward home-theater or subwoofer connection, particularly for buyers who value clear connector labeling and dual shielding. It may be less attractive than a multipack for multi-device installations, but its simplicity makes it useful for a single, well-defined signal path.
Clear Left and Right Identification
Color-coded connectors reduce the chance of reversing stereo channels. Secure grips also make repeated connection and disconnection easier, which is helpful when moving equipment or testing a different signal route.
A Familiar Adapter for Common Systems
The two-female-to-one-male configuration is well suited to distributing a source to left and right amplifier or subwoofer inputs. Dual shielding supports reliable audio in a typical home entertainment environment.

Buying Guide – How to Choose the Best RCA Y Adapter Splitter Cable
Choosing an RCA Y adapter starts with the direction of the connectors and the exact signal path you need. After that, cable length, shielding, conductor construction, included quantity, and equipment compatibility determine which model will work most conveniently.
Confirm the Connector Direction
The connector direction is the most important selection factor because Y adapters come in several arrangements. A one-male-to-two-female adapter accepts a male-ended source and provides two female input sockets. A one-female-to-two-male adapter provides two male plugs that meet at one female socket, while a two-female-to-one-male adapter splits one male source into a left and right output pair. These products may look similar when rotated, so read the listing carefully rather than relying only on the shape of the branch.
Understand the Intended Signal Path
Some Y cables split one mono signal into two paths, while others combine stereo signals into a mono path. The correct operation depends on the equipment and its circuitry, not just the connector names. A subwoofer, for example, may have a mono line input, whereas an amplifier may have separate left and right RCA inputs. Before buying, identify whether the source supplies one channel or two and whether the destination expects one combined input or a stereo pair.
Choose an Appropriate Cable Length
Short adapters are convenient behind tightly grouped receivers and amplifiers, while longer cables make it easier to reach a subwoofer or equipment placed elsewhere. The featured selection ranges from approximately 8 inches to 15 feet, including three-, six-, and 12-inch designs. Choose enough length for a clean route without creating unnecessary excess. A long cable that must be folded repeatedly may be harder to conceal, while an overly short adapter can force a sharp bend right where the cable leaves the connector.
Evaluate Shielding and Conductors
Shielding helps protect low-level audio signals from electromagnetic and radio-frequency interference. Copper braid, aluminum foil, or a combination of both can help reduce hiss, hum, and unstable behavior in systems with power cables or electronics nearby. Conductor material is another consideration: oxygen-free copper and other high-quality copper constructions are commonly promoted for stable transmission. These features do not determine compatibility, but they can improve the cable's suitability for a permanent or noise-sensitive installation.
Assess Connector and Jacket Durability
The connector shell and cable jacket experience the most repeated mechanical stress. Gold-plated or gold-contact connectors are intended to resist corrosion, while metal shells can protect termination points from impact. Flexible PVC, braided nylon, and high-elasticity jackets differ in feel and durability. A braided jacket may be a good choice for a frequently handled cable, while a longer run can benefit from a flexible jacket that bends without taking up excessive space.
Check the Included Quantity
A single adapter works well for one simple signal path, but multipacks can be more convenient when several devices need the same configuration. Two- and four-packs also provide spares for car audio, secondary rooms, or temporarily disconnected equipment. The included quantity should be matched to actual installation needs rather than chosen solely on quantity. It is also important to recognize that several listed adapters are Y-shaped splitters, not pairs of independent left and right extension cables.
Confirm Equipment Compatibility
The listed applications include subwoofers, home theaters, HDTVs, game consoles, Hi-Fi systems, amplifiers, DVD and Blu-ray players, televisions, and car audio equipment. Compatibility still depends on the actual connector layout and signal format of each device. Check that the adapter's common end can physically connect to the source, that its branch ends fit the destinations, and that no additional driver or software is required for the intended use.
Plan Cable Management
The correct adapter can still create a messy installation if excess cable must be folded behind equipment. Short Y adapters suit compact cabinets, whereas long cables may require ties, clips, or a route through a raceway. One featured model includes reusable cable ties, which is helpful for a 15-foot run. Plan how the cable will bend, where the Y branch will sit, and whether connectors will be under tension before finalizing your purchase.
How to Use and Care for Your RCA Y Adapter Splitter Cable
Begin by disconnecting the equipment and identifying the direction of the signal. Connect the adapter's common end to the intended source or input, then attach the appropriate RCA cables to the two branches. If you are using a male-to-female model, the male end normally plugs into an existing source connection while the female ends accept cables leading to destination devices. Never force a connector into a socket that appears to be a different type.
Route the branches without sharply folding them at the Y junction. Keep RCA cables separate from power cords where practical, avoid pinching the cable beneath equipment, and leave enough slack at each plug that normal movement will not pull on the connection. For longer runs, use the supplied or compatible reusable ties to bundle excess cable and keep it clear of fans, ventilation openings, and walking paths.
For care, unplug the cable by its connector rather than pulling on the wire. Do not use solvents or abrasive materials on the jacket or metal shells, and keep the adapter away from moisture and extreme heat. Periodically check that the plugs remain secure and that the cable shows no cracking, sharp bends, or damaged shielding. Replacing a compromised adapter is usually more effective than troubleshooting intermittent noise.
Frequently Asked Questions
What is the difference between a 1 male to 2 female and a 1 female to 2 male RCA Y adapter?
A one-male-to-two-female adapter has one male plug and two female sockets, so it commonly takes the place of an existing male-ended source cable and provides two destinations. A one-female-to-two-male adapter has the opposite direction, allowing two male-ended cables or sources to connect at one female input. Confirm the direction and signal format before ordering.
Can an RCA Y splitter connect two subwoofers to one receiver output?
It may provide the physical connection, but the receiver and subwoofers must also support the intended signal arrangement. One mono source can be divided into two paths only when the connected equipment and amplifier setup support that operation. Check channel requirements and any manufacturer guidance before adding a second subwoofer.
Do RCA Y adapters reduce audio quality?
A properly constructed adapter should not significantly degrade audio, especially over a short distance. Poor connections, incompatible impedance, a long unsuitable cable, or an incorrectly wired Y configuration can cause noise, hum, or imbalance. Shielding, sound conductor quality, and secure contacts help maintain a stable signal.
Do I need another RCA cable when using a Y adapter?
It depends on the equipment and the adapter. Many Y adapters are short splitters rather than complete source-to-destination cables, so additional RCA leads are usually needed to reach the destination equipment. Check whether the source already presents a male plug and whether the destinations have female sockets before purchasing additional interconnects.
Is a female-to-male RCA adapter better than a male-to-female model?
Neither direction is inherently better. The correct choice depends entirely on the sockets on your source and destination equipment. A female-to-male model is useful when the receiving device has a female input, while a male-to-female model is useful when a male-ended source must feed female inputs.
What cable length is best for a subwoofer connection?
The best length is the shortest one that reaches without creating tension or a tight bend. A short adapter works well for a subwoofer beside a receiver, while a longer cable may be needed when the subwoofer is several feet away. Avoid leaving large loops of unused cable, and secure longer runs to reduce movement.
Can one RCA Y cable carry both left and right stereo channels?
Some two-female-to-one-male adapters are designed for a left/right pair to combine into a compatible stereo or subwoofer connection, but this depends on the receiving equipment. Other one-to-two splitters divide a mono signal. Always check the product description and the channel layout of both devices.
Why does an RCA splitter produce buzzing or humming?
Common causes include a loose connector, a poorly shielded cable, interference from nearby power wiring, or an incompatible signal arrangement. Try reseating every plug, confirm the channel configuration, and route the cable away from power cords. If the noise persists, verify that the adapter's connector direction and split or combine function match the equipment.
Final Thoughts on Choosing the Best RCA Y Adapter Splitter Cable
The MOSWAG eight-inch splitter stands out as the most balanced overall option because it combines a one-male-to-two-female format, double shielding, oxygen-free conductors, metal connector shells, and a durable braided jacket. The Amazon Basics adapter is ideal for a simple left/right subwoofer or amplifier path, while the Arklove two-pack offers a premium construction for compatible dual-amplifier installations.
Whichever model you choose, prioritize connector direction, signal format, and physical reach before focusing on smaller construction details. Shielding, conductor quality, gold-plated contacts, and a flexible jacket are useful for long-term reliability, but they cannot compensate for an adapter that does not match the equipment. A multipack is especially helpful for multiple rooms, car audio, or keeping spare connections available.
Before making a final purchase, compare the current product page, included quantity, warranty information, and seller details, and verify every connector end. Prices and availability can change, so confirm the current offer and compatibility information at the time of purchase rather than relying only on this guide.
