I just hooked up a dvd/cd/mp3 player in my car. Everything works fantastic, but i'm getting a ton of engine noise. The unit did not have hook ups for my speakers so I had to run through an amp to get sound to speakers. Its a 250 Watt Crunch amp. When the cars not running all the sound comes out perfectly.

Is there a way to fix this cheaply or free? Maybe run wires a different way or mount my ground elsewhere?

My power wires is comming direct from the battery, the Ground is bolted inside the car under my console. The powers and ground for the stereo and screen are ran from the factory harness.


Its a 1990 CRX with Planet Audio stereo components

Thanks for any help
