Review on 🔌 Superflex Cable: SoundBox Connected 4 Gauge Red Amplifier Amp Power/Ground Wire by Ryan Brunson

Very flexible but strong. I used it to provide battery power to the fuse box in the back of my car. It wasn't so massive that I would have trouble installing it alongside the existing rocker wiring. At the same time, it was stiff enough to poke through a precut firewall grommet and some trim areas I didn't want to move. This means there is NO voltage drop at the rear of the vehicle. I put an 80 amp circuit breaker next to the battery and hooked up some heavy duty circuits from the relay that controls the fuse box. Make sure you have the correct cutters/pliers.
