Terrible Feedback coming from subs

[Squareone777]

i have 2 audiobahn a8000ts with 2 kicker L7s. when i have the volume on the HU at zero, theres very loud feedback coming from the subs. i know that its only one of the amps because i put every wire from that amp into the 2nd one and no feedback. this means it cant be the rcas either. does this mean the amps bad?

any thoughts would be appreciated. thanks

Check the ground connection on the amp that's producing the noise. It's sounds like a bad ground.

it cant be a ground tho cause i put the same ground into my other amp and there was no feedback from that one

Lower the gain on the amp that has the problem. Let us know what happens.
