Best for Short-Term UseKnuKonceptz KCA Complete 4 Gauge Amp Installation KitCheck Latest Price
The KnuKonceptz KCA Complete 4 Gauge Amp Installation Kit is unique both in its wiring and its construction. It includes KCA wire, or Kolossus Copper Aluminum wire, which is unique to KnuKonceptz. This wire isn’t rated for a set amount of amps, but it is made with copper-clad aluminum wire that’s conductive and affordable. The wire is actually larger than typical AWG wire — about 40 percent larger — and can achieve performance that’s similar to oxygen-free copper wire. You get 18 feet of 4-gauge KCA power wire, three feet of 4-gauge KCA ground wire, one inline fuse holder, one 17-foot long Bassik RCA cable, and 20 feet of 14 gauge CCA speaker wire.

The TopStrongGear 8 Gauge Complete Amp Kit contains everything you need, and all of the different wires and components included are great in their quality. You won’t just get wires that get the job done; you’ll also get the terminals, fuses, and additional accessories like wire ties that you need. The wire alone is worth the cost of the kit — you’ll get 17 feet of power wire, 3 feet of ground wire, 20 feet of speaker wire, 17 feet of RCA cable, and 17 feet of remote turn-on wire. All of these wires are wrapped in soft-to-the-touch insulation that’s both flexible and protective, making your amp wiring more durable for the long haul. Along with the wires, the included fuse, fuse holder, and terminals are all made from quality materials. Together, the parts of this amp wiring kit help your vehicle deliver clear, powerful sound from any speakers. There’s just one drawback to this amp wiring kit: the included wiring terminals are quite small, which can make installation tricky.
- Always check the gauge measurement on your amp wiring kit. While there are a variety of widths, a safe starting point is an eight-gauge kit. Also note that some companies claim that the wires are a specific gauge when in reality, the size is significantly smaller but wrapped in insulation to give the illusion of being bigger.
- Fuse holders are critical components for any amp wiring kit. For the best results, look for kits that include either ANL or AGU fuse holders. These options are easier to install and also feature indicators for a blown fuse.
- Cheaper is not always better, especially with an amp wiring kit. Invest in a kit with quality components that have longevity and are sturdily built.

Q: What tools should be included in a good amp wiring kit?
A: Look for amp wiring kits that include all the necessary tools to complete your installation job. In particular, they should feature the following items: quality RCA cables that are at least 16 feet long, a positive wire that is at least 18 feet long, speaker wire, ground wire, a remote wire, crimp ring terminals, a fuse holder and fuse, and zip ties.
Q: Should I pick copper or copper-coated wires in an amp wiring kit?
A: While copper wires are more expensive than copper-coated options, they’re usually a higher quality option because of their conductivity and strength. Copper-coated wires are made with aluminum and are considerably cheaper than copper wires. However, if you do your research, you can find copper-coated wires that are just as conductive as copper wires. Ultimately, the choice between copper versus copper-coated may come down to your budget.
Q: How do I know which size amp wiring kit to buy?
A: This depends on the wattage (RMS rating) of your sound system. The following outlines the size guidelines:
- 0/1 AWG for 1000 watts or more
- 4 AWG for 400 to 1000 watts
- 8 AWG for 200 to 400 watts
- 10 AWG for 100 to 200 watts
