when i was having my 4 channel pioneer amp looked at, i bought a sony xplod 9?? 4 channel amp until i got it back and tha sound was beautiful....on top of that, my subs 760 watts were connected too and all this on an auotzone battery...lights didn't dim or anything....from what i've heard, just use a lil bigger gauge wire and you should be ok, but with 220, you're more than fine...no new/added battery needed!!
TYRONE BIGGUMS is my mechanic, whose yours??!!!
