I have to cvx kickers with dual 2ohm voice coils. a kicker zx1500.1 and a stock premium pioneer system. I want to install a new head unit. I have the pioneer avh x5500bhs picked out but dont know if they have a dash kit and wiring harness for my car. has anyone else installed this radio? I know crutchfield dot com has it with a kit to make it happen but they want 500bucks versus the average 360 anywhere else without the dash kit and harness. this things expensive enough I need a cheaper route than crutchfield...
