Hey guys I just wanted to know, in my new car I have only one place to ground my subs and that is a seat bolt. I have found that my subs pop whenever I turn off the car, and I am told by a local shop that it is because seat bolts are not reliable grounds.

So anyways I wanted to know if anyone has run another cable all the way back to the engine bay and just grounded it either on the chassis or the car battery ground. If this works I am going to do it just because I have no other place to ground it in the trunk. Thanks

Matt
