benz280se Posted May 16, 2008 Author Report Share Posted May 16, 2008 thanks for your replies right now i am using 4 gauge wire since i had it already in the vehicle, and the terminals on the amp accept 4 gauge. when i get more money and time i'll add 0 gauge, but in the meantime, i will get a 160a fuse then. thank you guys a lot.
