So my buddy's truck has a nasty whine interference.
When we did the original install everything was fine. We removed sub amp and subs. Now the 4 channel has a ridiculous whine.
I replaced the ground, remote, and Rca's. I reran the rcas on the opposite side of power and remote. Have tried inline sound isolators and nothing works?
