I got a Kenwood double din multimedia receiver, metra wiring harness and dash kit. I works fine through the ACC, when I turn he car on, it turns off, and has to be reset by unplugging and plugging in the harness. I'm sure I just have a switched wire or something, any help is appreciated.

 

Metra wiring kit? Which one? Did you install adapters or cut and splice the oem wires?
is your oem stereo the Pioneer unit with the subwoofer? Or the base 6 speaker unit.
