run a seperate ground. most likely because of the kind of radio. it may not have isolators in the internal power block to keep out engine and such noise. kinda like a cb radio with your HID's on.

the ground comes from the antenna wire is that suppose to do that?cause i disconnected the ground and it still played with the antenna wire.

I have had some radios that would do that. I sure wouldn't rely on that alone for your main ground though. I have a Dual in my Aspire and it's okay except sometimes it loses all the presets when you start the car. I've read it is a common problem with that model.

RCAs

I was just wondering if you use RCAs off your head for anything, like wires to your amp? If they slightly unplugged it will make it whine.
