oops you're right, i got a little mixed up. but anyways, i picked up that cheap head unit at best buy (pioneer deh-1600, newer version of last year's deh-1500 i think), it was $110 and comes with a free $20 giftcard, so it seemed pretty good. when i get everything installed (my friend said he might be able to do it on tuesday), i'll update with the results. as soon as i get more money, i'm definitely replacing this amp.
oh yea, and one more thing. the head unit i got only has 1 preamp output for the rear...i can hook up my amp and subs through that, right?
thanks for all the help
