[QUOTE="req, post: 573179, member: 555713"] i would say 120~150. dont use any more than 150 amps on a 4awg wire, i would step up to 2awg for anything over 125 IMO... then 150 = 1\0awg... but thats being careful. i have a 120 amp fuse on my 1100w amp (but im only pushing it @ 2ohm\800w atm) with a 4 channel amp ~20amps for that maybe .... i guess im using ~100 amps for my whole setup.. i would use at least 120 fuse. maybe 130 or 140. you can get packs of 5 that go from 100->150, just put a lower one in, if that blows, you know its A. too small of a fuse B. too small of a wire =) - a quick way to guage the number of amps, is to add all the fuse ratings that your amp has built in, and get a rough estimate that way. my amp has 2x40amp fuses. so i guess its max current is ~80 amps. +20amp fuse for my little amp= 100amps... im not even NEARLY taking 1100w@1ohm from it, so i think im safe to say im pulling alot less. thats just a guesstimate tho. i cant find a 200amp ammeter [IMG]//content.invisioncic.com/y282845/emoticons/bawling.gif.6287aa5d1d447c8af063fc9466e822ef.gif[/IMG] [/QUOTE]
