Hey, I drive a 99 galant and I need to get 1 Infinity Perfect 12 and a Rockford 400s amp installed... Anyone off the top of their heads know how much it would be? I will be installing this to the stock CD player for money reasons right now... But I will eventually get an aftermarket deck... So don't say I should just buy a new deck before I install... I also have MOST of the wiring needed I think... The wire that goes from the battery all the way back to the amp I think isn't long enough so I will have to have a little more of that or a new wire all together... Everything else I think I have... So what do you think this will cost?
