Sony Mobile ES Amps.720 watts for 2 sets of 6.5" and 1 set of 5.25" and 1 set of 4" component highs and mids. Got it in.!!FN LOUD!!even the mids hurt your chest and I haven't even got the sub in yet.I hope 1000 watts of bass is loud enough to be heard over the highs but now that KICKER makes the VX I'm sure it will sound great.SUB IS IN!!!!!! Holds its own 2. Here is construction pic. I'll get a completed one up soon.
