Wierd System Problem. Thoughts?

I'm haveing this wierd problem with my "system". When I have my radio playing a CD once it has all "warmed up" when ever I skip a track or it moves to the next the Sub goes "thud.... thump" loudly. Then plays, and it gets progresivly worse the longer its on. Wierd part is it even does it when the sub is muted, and it also makes the noise switching between modes (CD/AM/FM/AUX) Even changing stations. So any thoughts on what may be causeing this or how I can track down with component it is? Thanks!

My sub did that until I ran a "remote on" wire from the headunit. The sub's amp was powered up, but wasn't getting signal. When the headunit powered up, the sub would pop. Is your sub self-powered?

No, The amp has power and the remote works.

I think I may have traced the problem to the Head Unit its self. When I swich the Amp to a differant Pre-Out the problem goes away. My HU has a dedicated Sub channel (3-PreOuts) So off to Best Buy I go to see about getting this thing replaced. Gotta love the Service Plan!

Thanks for the couple of suggestions.

Sounds like you figured it out. Definatley a headunit issue if it goes away when you switch pre-outs. Sounds like that channel goes to sleep when you change functions, then surges back. Not good for your sub. Definatley replace that thing.

Does your amp have any "auto turn on" features?

Some amps will essentially look to the input signal to determine if music is playing or not. Sounds like whenver you are changing tracks or whatnot, the signal dies, and the amp thinks it should turn itself off. This is actually normal, but alot of the newer stuff has features to prevent this as it does damage speakers in time.

The fix would be to diable it at the amp(if possible), or switch to RCA's which typically do not have this feature on it.You could also install an inline switch on the remote line to kill the amp.

Nope, I dont have that fancy stuff

I'v had this amp for about a year now and had it on two differant HU's and this problem is only on this one..

Funny thing. So I get to Best Buy to get it replaced and its not doing it now.. isnt that how it allways happens... Maybe I got lucky and moving the cable behind the radio fixed it? Doesnt make sense when it works on a differant line, but who knows... maybe I'm missing something.
