    I think he has everything stock. But he will need a new head unit to hook up the amp to stock speakers.

    Default OEM HU + OEM Door Speakers + AMP + 2 , 10' Subs'

    Hey guys its all figured out already. I installed two 10'' inch Memphis audio's in a downfire box with a 1000 watt Memphis Audio amp and kept the origanal HU and factory door speakers. It was a good buy my friend was selling all three for 150 bucks. I'll be buying different door speakers and tweeter's once I blow out the factory ones that I have. I used my HU's dimmer wire (yellow wire on the right side when looking at it from the seat) as my remote. That way if five O is near me at the stoplight i just drop down the dimmer light on the radio and the system is off :na:. I bought an RCA conversion kit and tapped into my front right speakers by the kick panel on the passenger's side. The wire colors are light green (+) and dark green (-). I split the rca with a Y adapter and plugged into both ports. I adjusted my amp so that I don't have to use much bass on the HU its like two clicks below medium. Tell you the truth it sounds freakin awesome especially for what I paid.

    Default remote wire

    be careful having the remote connected to the dimmer because I have had people come into my shop complaining that their dash lights went out and it was because something was being powered off the dimmer. i would suggest you go to the ignition harness to get the remote off a true acc.

    I connected my remote wire to the very dark brown wire that is part of the ignition harness. There is a strip of vertical wire harnesses. The dark brown wire is in the top harness its sort of a teal color. I just hooked mine up and put a little paddle switch on my dash right beside the steering wheel column
