Best Overall: Topstronggear Car Audio Amplifier connection

Buy on Amazon

The look and feel of this connections are consistent with the high quality we're used to from the rest of Topstronggear's lineup. It is perfect kit for a 4 door car. It’s only power cable inside and one small speaker wire and one RCA. The power wire and ground are good quality. It’s a bit thin, difficult to strip with pulling the copper underneath with it. It comes with instructions on how to install or guides as to where to find the way to install them.

The cable is pretty thick. It’s good for over 1000w, but the fuse is only 80amp and the fuse holder is the weak link because it is an 8 gauge fuse holder. They fit amazing minus the function key and the left mouse key beside that. It is easy to loose screws.

• Comes with everything needed and the quality is great
• Power and ground wires worked great
• High quality cca 4 gauge wire
