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 doesn’t 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

Great value for money
Works great for the price. everything set up to plan, although I recommend buying wire shrink separately because what comes with this set is very cheap and doesn't shrink well at all.
