I have a Kicker zx200.2(30 amp fuse, pushing about 70wattsx2, class A/B) and zx400.1 (40 amp fuse, pushing about 400wattsx1, class D) and wanted to make sure I am adequately power them. I was thinking 4guage wire to 100 amp fuse under the hood, should I go smaller like 80 amp?...then to distribution block in the back which will then feed a short run (1 or 2ft) of 8awg to both amps. Would I be overkill to do 2 awg to the back to dist. block and do 4awg to zx400.1 and 8awg to zx200.1? I beleive in giving the amps the correct power what do you guys think is good for this setup?
