Howdy,
I have two amps, a 4 channel for speakers and 2 channel for subs. From my battery, I have a 4awg run with a 60 amp fuse at the battery, and this ends at a 2 gang distribution block. From there I have a pair of 60amp fuses and 8awg wire that runs to each amp. The whole setup worked fine for about 6 months until the fuse for my 2 channel amp blew. I replaced this, only for the fuse under the hood to blow immediately. (I've also had each of my amps replaced once, probably do to this same issue).
I originally thought this was a grounding issue, but I believe the issue would have been apparent 6 months ago...
After consulting Crutchfield, it turns out I was using incorrect amperage fuses. My 4 channel(1600watt) is 20a x4, while my 2 channel(2200watt) is 25a x2. So 4 channel needs 80a, and 2 channel needs 50a, and the battery fuse should be 130a....I was using 60a for everything.
Now I am hoping if I use the correct size fuses, my problem should be fixed.
I now have 2 questions...
1. Should I run two 4awg wires vs having a distribution block?
2. Under the hood, should I use a circuit breaker vs a fuse holder? 130a fuses seem hard to locate locally.
I really appreciate any and all help you can provide.
