[QUOTE="RobGMN, post: 8766368, member: 683408"] It almost sounds like the compressors radio stations use. When things got quiet too long, you could hear the gain come up and a nice background hiss. Then when someone broke silence, it would clamp down and get REAL quiet for a moment before leveling out. It almost sounds like your head unit is auto-muting, then kicking back in once it gets a solid signal, or the amp is doing it (similar to the auto power-on concept for a home subwoofer). The extra switch is not a terrible idea. I had an older system that had a nasty turn-on thump b/c the head unit booted after the amp was already fully powered. I actually added a timer to delay the amp turn-on signal. A switch would have worked too. You are at a point of diminishing returns: Go through the troubleshooting process to isolate the problem, and then figure a way to fix it, or just take the easy route and do the partial fix and learn to live with the rest.
