Gets the job done
Was at my door within 24 hrs of ordering. Had an extra sub and amp in my garage but needed wires and wanted to throw it in my work beater. This got the job done for $24 and now we BUMPIN

Good for for the money - CCA 4 AWG
Better than I expected. Used this to install a 4 channel amp on a drift car. The power wire is CCA (Copper Clad Aluminum) which for this application was great because I didn't need a ton of power and it only weighs about 1.5 lbs (easily 10 lbs if pure copper). Fuse is kinda cheap but it does the job. Speaker wire is CCA so that should probably just go in the bin but even without that it's still a good deal. I wouldn't use this on a high end install but this kit definitely has its place and I was happy with my purchase.

Great quality just a little misleading on wire size
Quality kit, only complaint is that the power and ground wires are not true 4 gauge. The actual wire itself is more 8 gauge, the sheath is of 4 gauge size just not the wire.

Used to install a 2400 watt subwoofer amplifier
Everything I needed including wire ends for a sound stream 4500.d amplifier. I installed in a 3rd generation Tacoma (2021 TRD sport) behind the rear seats and had about 4 feet of extra positive 4ga wire. I think it would be more than long enough for most sedans. The power wire is full 4ga and copper coated for great electrical properties. It doesnโt get warm when driving 1600w-2000w to a pair of 10 inch subwoofers. Speaker wire is also very thick and easy to strip. The RCAs have good ends and seemed to block an interference from the power wire (I ram signal and power close together for better packaging. I would buy again and saved 59 dollars vs other brands. Highs Great value Good quality Works for a 2000-2400w amplifier Easy to strip wires Good wire flexibility Long enough for most installs

Works good except for fuse also power wire not long enough
Everything that came included was pretty good but your power wire at least for my car I needed more length I would recommend 20 feet or more and then the fuse!!! IT BLEW IN JUST 2 DAYS just make sure this is the one you want to get. before you buy.
