Nissan-R

I have a fuse between the battery and power cable, which is connected to an unfused distribution block. My question: Do I need to add an in line fuse to the power cable--the cable between the distribution block and the amp ?

Thanks.

I have a fused distribution block and I think you need to fuse individual wires coming out of the unfused distribution block. That would protect individual amp and wires. Let say you have a short on one leg or it draw too much current, it would just blow the fuse on that leg rather than blow a main fuse and short out the whole thing. You would put lower rating fuses in the individual leg and put a higher rating in the main fuse. If you don't have them individually fused, that one high fuse is not going to protect individual amp, it just protected the whole system from drawing too muc current. Hope this help.
