I am fixin to buy this amp and needed to know a couple of things first. This amp has no internal fusing and says it needs a 160 amp external fuse. i looked and i couldnt find any 160 amp fuses. so what im wanting to know is this external fuse is just the 1 up by the batt right? And i have a 20 farad cap if i hook it up will i need to fuse it before the amp? i know on amps with internal fuses u dont. and last i need to know if i use a 200 amp anl fuse is that goin to be to much since amp dont have internal fusing? If so how would i get a 160 amp fuse because i cant find them.
