in my 93 chevy i have a box under the box seat with a 8in kicker speaker (just one) every now and then i will notice the speaker kinda kicks out, the bass sounds like sh!t but all the other speakers work, then if i turn the bass adjustment up it will kick back in but then when i turn it back down to normal it will sometimes kick back out. whats going on, it never did this before, is the speaker blown? if so i guess thats a good reason to put the cerwin vega 12's i got in it /forums/images/graemlins/grin.gif
