NEVER upgrade the fuse that comes with the amp. Lets say you have a 40amp fuse in your amp, it blows, you put in a 60 amp fuse. You aren't helpign yourself anymore. Because if something comes along at say, 50 amps....the fuse isn't going to blow, the amp is going to take all the extra power. Which isn't good.
Heres my setup.
I have a 0/1 Gauge wire running back from my battery to my distrubution block. I have a 200amp ANL fuse on that line.
Now, my distrubution block is a 4 way that has spots for fuses for each amp. My sub amps each take 2 30amp fuses in them. So for the cable on the distrubution block that supplies power to them, I have a 60amp AGU fuse. My 4 channel amp has 2 20amp fuses in it, so yep, a 40amp AGU fuse in the distrubution block for that sucker.
I probalby should see if I could find a 160amp ANL fuse for my main line, seeing as that 200amp fuse isn't helping me at all.
