  • Works great, good price
Color: Green
good quality wires that came with everything i needed to get power to my amp. good color options and the installation was straightfoward and easy

  • Great kit!
Color: Red
This honestly was a great kit, especially for the price! My only complaint, as with every other kit on the market, is that the ground wire could be just a little bit longer. 100% will purchase this kit for my other vehicles!

  • Good power wires
Color: Green
Good power wires. Everything else in the kit is cheap like in line fuse holder and RCA’s

  • Decent value - good set of parts, but the fuse was DOA
Color: Red
Most of the kit was good to go. No issues with the wire. Would have been nice to have some terminals that worked with the ground wire, which is too small for the 4 gauge ends, but too large for the little blade terminals. The really irritating thing was the fuse was dead to start with. Based on other reviewers having the same experience, if you buy this kit, go ahead and order extra AGU fuses from Amazon, so you're not like me and driving to the AutoZone just before they close so you can finish up an install. ... show more

  • Great Value for the money.
Color: Blue
The 4 gauge wire is great. Everything all around is pretty nice but the only thing I’d change is the fuse. The glass fuses tend to overheat and melt. Other than that great bang for your buck!

  • My go to from now on.
Color: Blue
So this kit is top quality. I’ve had boss and other more expensive brands before and this is by far the best. I watched a video of speaker wire testing and they rated this number one and I have to agree. All the connectors are solid and not cheap either. For the money you cannot beat this kit.
