does anyone know were ot get a diagram for pioneer plugs i need ot figure out whic hwires i need to use. also what do u do if your sub channel is only one plug i didnt get this. one last thing. can i run a amp with the signal from regulare front or rear channels

All(ok maybe like 99%) of aftermarket revivers whave the same wire color codes that go as follows: Black:Ground, Yellow: B+(constant), Red: ACC(switched). Ok the speakers are solid for the positive wire and the negative has a black stripe..the colors are: Grey: Right Front, White: Left Front, Purple: Right Rear, Green: Left Rear. The illumination wire(if present) will be orange/brownish and the amp turn-on and/or power antenna will be blue(sometimes there are 2 seperate wires, sometimes theres only one)

The sub question...i think your asking if your HU has a mono output for the subs and your amp is stereo, then get a Y-cable to split that mono signal into two, unless your amp is mono, in that case the Y-cable is not necessary.

Your last question, i think your asking if you can use the actual speaker wires from the HU to get signal to the amp, the answer is yes, as long as your amp has a specific input for that.
