ok, i have an audiobahn 15" subwoofer (1200 watt peak)with an 800 watt amp. everything was hooked up and working fine. One of the screws on the terminal was missing, so the connection was weak and the sub would go in and out. I bought a new terminal and took care of all that. everything seemed to be working fine, then today im driving down the road and it just completely cuts out. before when it would cut out i would turn it down or off, and then a few minutes later it would be hitting again, but when this time it wouldnt. when i got home i checked all the connections, everything seems to be tight, and the amp powers on, what could be the problem?

(it was dark when i checked everything, but i tightened it all up and plan on rechecking everything tomorrow when its a little brighter out)

any suggestions are appreciated
