So up until now my system has worked fine, but recently I've been having a few problems.

1. I now sometimes get a popping noise from the sub when I turn on the car.

2. Sometimes (randomly) the sub will stop hitting, then when I turn down the music all the way i just hear it back there vibrating and thumping randomly, then I turn the stereo off and it still makes the same vibrating and random thumping sounds (with everything off) and will do that until it randomly decides to kick back in. Sometimes even if i turn off the car then turn it back on the sub does the same thing, then will randomly start working again.

Any ideas?
