i think i wanna run the jbl bp 1200.1 with 2 infinity perfect 12's(2 ohm->1200rms), and was wondering what type of wire i should use....would 4 ga be enough, or should i go with bigger(0/1ga.)...and what type of fuse should i use?...

As long as the length isn't over 16' or so 4 will be plenty.

4 guage should be fine if the JBL amp is all you are running off it.. What is funny is that a 60 amp fuse is all you need regardless of the three 40 amp fuses on the amp..My friend is running the same set up and hasn't had any trouble.. but you may want to consider a cap to go with it.

I am also thinking about a JBL 1200.1 and my car is quite large so I have 20 feet of 4 guage! will it work?

lhs roller i dont know if that will work to well or not i was lookin at the setup in an lhs with around 20 feet of wire and that much power according to eatel.net you should use at lest 2 gauge but i think that you could probly get away with 4 id go with it and try it first if somethin happens you can always sell the wire and get bigger stuff
