Turn the sub amplifier gain all the way down, connect the RCA, then properly reset the gain.

I hope you mean you connected the RCA wire for the sub amp to the radio OUTPUT, not input.

Is it a Pioneer Radio? Hey JMelton did you ever get your noise at bay?

No. I need to give my rear battery a better ground, check my bass x-over for bad power/ground connections, and check all ground resistances from HU to amp, amp to x-over, etc...

It's a pain.
