Noise Coming Through Subs

the shield is the outer metal. you can use a DMM to measure resistance between the amp rca jack shields and the amp chassis. older amps can be more sensitive to grounding issues (though 11 years isn't that old). i like the RF bd series as well, a great amp. try some shield grounding before you replace the amp.

Just got back from a friends house, where I installed my amp in his car. Same problems occur. So, it's definitely the amp. And I'm definitely feeling like it's the RCA input block. The red and white plastic parts are loose on the input side, and wiggle around inside of the metal shielding. I must have yanked on them or something when I was unhooking the amp.

Would this be an easy repair? What might it cost at a shop? I'm going to call a shop tomorrow and ask. But, I'd love some input on how easy or hard this might be. I looked around for an RCA block, but I couldn't find one to purchase that looked like what is in my amp. At least I know what's going on now, for sure.
