Got myself a nice new Boston 10" sub about 2 weeks ago, which sounds great. Got in my car this morning and it's not working! My amp is on cos it's lit up, all connections are in place too. Does anyone have any idea what it could be. I have definately not overpowered the sub so it hasnt blown. Theres speaker does vibrate slightly but not enough to create any sound at all, which probably confuses things more.
