Im having problems with my pyramid 240 watt 2 channel amp. I have it running my 2 rear 6x9 speakers. Whenever i have my car turned off it works fine. But when i turn it on im getting some wierd high pitched noise and it wont play. I have the power, remote, and audio cables bundled up going to the front. The ground is on the chassis a couple feet from the amp. And the speakers are hooked directly up to the amp. Could someone please tell me how to fix this because I am baffled. I think it is some kind of interferance but I dont know how to get rid of it.
