white/black is negative
grey/black is positive
white/red is amp turn on

the way I do it is get an rca end (male) and cut it and tap the negative side to the white/black wire and the positive side to the grey/black wire and then plug it inot the sub out from your aftermarket deck. as far as the amp turn on goes; put a 1k ohm resistor inline with it. it will work without that, but you'll get a popping sound everytime it turns on. and this is all the the thrid plug behind the radio. and questions let me know, and GL

Easier thing to do is stop by a best buy and pick up this part...Part number is RCA4 and what it is 4 rca's with bare wire on the other side...no need to cut up good rca'a and guess which is positive and negative...you can wire up 2 rca's just run the positives together and the negatives together and you will be fine

ok so double up that makes sense cause if u had 1 ud be losing sound cause even though itts mono it still plays left right now that i understand that perfectly still a lil confused about the power for the amp i guess it hooks up to the same 12v that the radio uses to turn on and then thats it 3 wires? no grounding anything cap all the old wires?

the amp has its own power and ground...all you have to provide is the signal (rca wires) and a remote turn on lead which the aftermarket radio will provide..
