I put a 12" alpine type R in my super cab with a sony explode 1200 watt amp and a decent cd player. when first installed everything worked great, not to long after the sub started to pulsate with the fuel pump. i would pop the face of the cd player off and it would stop and now it keeps doing it. yesturday i tried grounding it to a different spot and now the sub vibrates along with my truck. i had an electrician look at quick (without taking it apart) and he cant figure out why its doing it. can anyone help with this????:shrug:
