  • Great Quality, Great Price!
Style: 4 Gauge
The BOSS Audio Systems KIT10 4 Gauge Amplifier Installation Kit is an excellent value for anyone looking to install an amp without spending a fortune on wiring. The kit includes everything you need—power cable, ground cable, RCA cables, fuse holder, and accessories—all packaged neatly and ready to go. The 4-gauge power wire is flexible and easy to route, but still feels thick and durable enough to handle solid power delivery. The RCA cables are decent quality, with minimal noise interference, and the inline fuse holder adds an extra layer of protection. I had no problem getting my amplifier hooked up and running smoothly. For the price, this kit makes the whole process straightforward and saves the hassle of buying each component separately. It’s not just convenient, it’s reliable—everything worked as expected and my system sounds great. If you need a complete, affordable, and dependable amp wiring kit, the BOSS KIT10 is a fantastic choice. ... show more

  • Perfect
Style: 8 Gauge
This is a perfect kit for most cars. I was able to install the kit in my 1999 Toyota Camry with no issues. It doesn't stand out if you hide the wires properly. The audio cable provides a clean signal. And the wire is quite flexible and fits in most routes. They really thought of everything like grommets in case you need to drill any holes and self tapping screws for grounding the system. ... show more

  • RCA cable no good
Style: 10 Gauge
The RCA cable is not worth your time. I replaced mine with a much better quality cable. I had a channel cutting in and out. Otherwise the kit is a good value

  • Seems to be good quality
