DEH P3500 No Sound

[EARLEH]

Am installing Pioneer DEH P3500. Every thing lights, Tuner Tunes, CD Player seems to be playing, but no sound!! Am I doing something wrong. Just using white and gray front speakers. I am not familiar with this unit. Something I should push or adjust outside of volume? Help, Earle

get DMM and test speaker wire you are connected to. Make sure they rest about 4 ohm and there is no grounding issue to the speaker wires. Also make sure the rear speaker outputs are well insulated and not shorting out. Finally take test speaker to the output of deck and make sure it is playing music while the vehicle speaker wires are disconnected.
