Well, I installed a pioneer DEH-P4600MP into my car tonight. I got all the wiring in right (I think). It plays and everything, but now it only plays in the front right speaker. What can I do to fix this? If this has alredy been gone over, please link me to the thread and close this one.

 

did you use new wire from the unit to the speakers or the stock line? you could have breaks in the stock lines or the unit could be faulty. make sure your harness is plugged in all the way to the back of the unit and make sure you gave yourself slack in the lines so when you put the unit back in they dont fall out. i have had that happen almost everytime i wire in a unit. did you use plugs, tape, or solder to connect the lines? also, make sure if you used all new lines they are the same guage

 

Fixed it, one of my friends attempted to wire 3 wires (happened to be speaker ones) while I went to get a drink.

 

what a dumb ****.

Glad you could figure it out.

 

ya, its better you do things your self... that way most things dont get f-up
