that is a total rewire!!!!!do they even make a dask kit for that?

you can get all power from factory deck, i would get my own ground from chasis, then run new wires to all speakers,

are those powered speakers in that car?
if not you can find factory amp, run wires to amp and use factory wires from amp to speakers,
if they are you may be able to use the wires going to speakers but will have to replace speakers with aftermarket..

if you dont want to do it will, just pm me

do they even make a dash kit for that?
i think that is custom ... or special order

you may be able to power up the factory system and cut a pair of rca's and plug them new radio and feed signal thru factory wires to factory amp.

i would do the rewire if it was mine
