Review on Pyle Channel Marine Amplifier Waterproof by James Townsend

Please note that I have multiple stereos hooked up in my car and I "know" the wiring diagram. This unit works when the ignition is in the "accessory" position (when the lights on the dashboard are on before the engine starts) and after the ignition it turns on again and doesn't play any music except my phone ( and AMP). both show activity. Assuming I did something wrong, I installed another stereo and tested it. I then checked the voltage for possible voltage drops and everything came out clean. I have contacted Revain and some of you have reported having the same issues. I contacted the company and got no response at all (bad sign). If it's a technical problem, then it's not obvious.
