Subs "Popping"

[Brad M]

I have a Pioneer DEH-5800MP Headunit. My problem is that when I have the rca's plugged into the subwoofer rear outputs, the subs will "pop" every time I hit the source button or adjust any of the subwoofer settings on my head unit. Now, if I use another set of outputs, the problem goes away, but I lose the subwoofer controls on my headunit since I'm not using the sw outputs on the stereo. Any ideas on what could be wrong?

BTW: I tried grounding the rca's, and that didnt work either.

dont change sources.....lol. no, is your volume cranked up when you do it? whats the ground look like for your amp? did you use a seat bolt? did you get all the paint off the metal?

I'll check it out. But it only does it when the rca's are connected to the "sw" outputs, but doesnt do it when they are connected to the "rear output" rca's...
