So I have what was a NIB Rockford Fosgate 4060 powering my ADS 320i mids. I have been running it for about a year now. Recently the RF developed a case of static on top of the music. Static seems to have no connection to the signal. I took the amp apart and can see nothing wrong - caps look good and no burnt areas. Is this looking at or should I just toss it?
Perhaps a noisy pot or switch? I had a similar issue (and intermittent loss of one channel) with an RF R400-4D. "Exercising" the respective 3-way HP/AP/LP switch back and forth a few times did the trick.
