Buzzing...but only when radio is on

[GrandMarkie]

When the radio is on, I get a constant buzz. When I switch to a CD, the noise disappears. All RCA cables are on opposite sides of power/remote turn on wires. A few speaker wires intersect perpendicular with the power and in the trunk, they meet as well. Thoughts/ideas? I'm just confused as to why only when the radio is on it is like this.

I had the head unit (Alpine 7897) in my old car and just recently put it in my new car. Never did this before, but I also never had 2 amps and a sub before either.

I'd bet it's a radiated noise problem you didn't have in your old car...

Does it buzz without the antenna connected?
