my nephews having some problems in his truck...everything plays fine, but when he turns is car on or off, one of his subs kind of pops... i looked @ it while he turned his car on and it does a full excursion and then slowly goes back to normal...any ideas on wats causing this? i checked his ground and all connections behind the head unit and everything looks good.

It may be a grounding issue or it is just the fact that the head unit comes on after the amplifier. The HU will send an "on" to it after it has kicked in. Higher end amps usually have a delay that will prevent that from happening.

Are the grounding points sanded down? The ground wire short as possible? No loose wires (including behind the HU, specifically the remote wire)?

This has been covered long long ago. Thankfully I remember where at:

HERE

Look up section 2.2 My system "pops" when I turn it off. What is happening and how can I get rid of it?

It's not good for the subs. If the poping is bad enough, it could cause the sub to over excurt, which definately isn't good. It seems to be worse in a ported box vs. a sealed box also.

mine just sounds like a certain hz of bass hits for a second, like thump its in a small sealed box so i doubt its over excurting
