Engine noise

hey my cars stereo is gettin horrible engine noise, i tried these filter things but they are useless crap, i was wondering if people know what might be th problem or how to fix it

Try changing plug wires. When they start to break down they will cause RF interference on the radio. If it is a 4 cyl. then change the spark plug connectors under the center cover on the engine.

sonds like a bad ground wire problem try grounding your stereo streight to the chasie i bet that helps

which color wire is my ground wire on my stereo..?

Black. Solid black.
