1. BOSS Audio Systems KIT-2 – Cheapest Amp Wiring Kit
- Gauges: 8
- Wire Length: 3, 16, 20 feet
If you are tight on cash, Boss Audio Systems’ Kit-2 is an affordable amp wiring kit that you should consider. However, with this price, you get an 8-gauge wiring kit, which is thin and cannot handle large amounts of electric current.
There is a much thinner 10-gauge option that is cheaper while a 4-gauge kit enables you to power up a stronger sound system, but is much more expensive.
Regardless of the gauge size, the kits contain a long 20-foot red power cable with a high-quality competition fuse holder, a 3-foot ground wire, a 16-foot turn-on wire, a 30-foot speaker wire, a 20-foot RCA cable, multiple rubber grommets and wire ties, and multiple terminals.
On the downside, the copper core used in the cables is not Oxygen-Free, which reduces its conductivity.

2. KnuKonceptz KCA-K4 – Good Amp Wiring Kit
- Gauges: 4
- Wire Length: 3, 17, 18, 20 feet
This Amp wiring kit consists of a 4 gauge 3-foot and 18-foot ultra-flex black and blue wire, in which the former is a ground wire while the latter is a power wire.
All these feature a KCA cable (Kolossus Copper Aluminum) core, which is KnuKonceptz next generation of Copper Clad Aluminum (CCA). This wire basically consists of 90% aluminum and 10% copper, and this results in better current transfer from the battery to the amp.
The 4-gauge width of the cables in this kit provides good flexibility and they are covered in a rugged PVC jacket that is resistant to grease and oil and can withstand extreme temperatures of -40 to 105˚C.
Other items in the kit include an inline fuse holder with an 80-amp fuse, a 20-foot 14-gauge CCA speaker wire, a 5-meter remote turn-on wire, a 5-meter RCA twisted-pair OFC cable, grommets, wire ties, and 4 gold plated 4-gauge terminals (2 spade and 2 ring terminals).
On the downside, this kit cannot handle a load of more than 100 amps and the CCA used is less conductive than Oxygen-Free Copper (OFC). However, CCA is cheaper than OFC.
Pros:
Cons:
3. InstallGear IG4AKR – Amp Wiring Kit with an ANL Fuse Holder
- Gauges: 4
- Wire Length: 3, 17 feet
InstallGear’s IG4AKR amp wiring kit features an ANL fuse holder, which is a particularly important electrical tool that is designed to protect the main power wire from the battery to the amp because this cable is very difficult to replace.
This fuse holder comes with a 100-amp fuse for the 4-gauge kit but the 1/0 gauge features a 150-amp fuse for high load systems while the thinner 10-gauge set comes with a 50-amp fuse for light load systems.
Regardless of the gauge, each set is equipped with a 17-foot CCA power cable, 3-foot CCA ground cable, 17-foot 2-channel RCA cable, and a 17-foot CCA speaker wire.
All these are covered in a soft-touch PVC jacket, with the RCA and speaker wires having black and blue jackets for easy polarity identification. On the downside, the CCA core used is not as conductive as Oxygen Free Copper wires.

How to Buy the Best Amp Wiring Kit
1. Included Items
Most amp wiring kits come with multiple accessories and installation hardware as part of the package, but it is still important to check the included components.
Generally, the best kit should have at least long RCA cables (minimum 16-17 feet) that are of good quality, a long power cable that is at least 17 feet in length, remote, speaker and ground wires, a fuse and its holder and terminals.
Other additional components are advantageous to have and the more they are, the better.
2. Gauges
This is a very important factor to consider because it determines the current load that the kit can handle. Gauge basically defines the width or thickness of the wire and the smaller the value, the thicker the wire. For instance, a 0-gauge kit contains thicker wires than a 4-gauge kit.
Thicker wires are ideal for powerful sound systems because they contain multiple strands inside that can carry a higher electrical current without burning out. Therefore, if your car’s sound system required more than 1000 watts RMS, the best option is a 0-gauge kit.
Most 4-gauge kits are good for 400-1000 watts RMS systems while 8-gauge sets are ideal for the ones that operate below 400 watts RMS.
3. Wire Length
This is a no brainer. The longer the wires, the better. You should avoid kits with power, speaker, remote and RCA wires that are shorter than 17 feet because these might be too short, creating tension once installed.
4. Fuse Holder
You should always select a kit with a good quality fuse holder such as ANL or AGU because they are easy to install, are water and heat resistant and usually show if the fuse element is blown. For this component, never compromise on quality.
5. Copper or Copper Coated Aluminum Wire
Pure copper or Oxygen-Free Copper (OFC) is generally considered as the best conductor of electricity as compared to aluminum. It is also very flexible but on the downside, can cost 4 times as much as aluminum.
On the other hand, Copper Coated Aluminum (CCA) is very affordable but has a higher resistance to current flow. This means that for extremely powerful sound systems, some of the power might be lost during transmission, thereby reducing sound quality.
Therefore, for such systems, it is recommended to use copper wiring kits for the best results.
6. Ring Terminal
Also known as lug terminals, these are included in some kits and are ideal for making a solid connection with the battery so as to prevent arcing and for easy drawing of current. Therefore, a kit with such components should be highly considered.
7. Installation
Installing an amp wiring kit is not always easy. As such, ensure that the one you buy comes with clear installation instructions so that you do not mess up
Conclusion
In summary, you must have an amp wiring kit for you to set up your amplifier and aside from the main wires and cables that are required and contained in most kits (power, RCA, speaker and ground wires, etc.), ensure that the set you buy has as many components as possible.
Another crucial factor that you need to get right is the gauge and that said, all these are clearly laid out in the article above so that you can easily pick the best amp wiring kit that befits your car’s audio system.
