Alright, wiring up a 2008 Mustang. When we connect rca's from the head unit (works for door speakers no problem), the amp goes into protect and the doors throw off an odd noise. However, if I hook my phone with a headphone to rca adapter into the amp, it works perfectly. We've tried different rca's, different grounds for the batteries, different outputs on the head unit, disconnecting the remote knob, and everything I can think of.
Suggestions, ideas, etc?
I used to have that walled Challenger, then it got totaled...
