sub dropout

I was riding to the galleria, sub is working fine, then bam, it just stops working. The music still plays but no sub. So i change cds and it still doesnt wok. Well later on im riding around and it comes on for about 2 seconds then off again. Then does the same thing like 2 more times. Then gos down for the rest of the day? Maybe it's a short? Please Help me!

more than likely loose, corroded, or both connection good luck crippledchicken

Perhaps there is a loose connection at power/ground/speaker. Perhaps the amp overheated. Perhaps the voice coil lead has broken off the speaker terminal. Many possibilities here.

What you first should do I guess is when the sub turns off look and see that the amp is still on and that the protection circuitry has not been engaged. A short will normally cause a fuse to blow, in which your speaker would not have turned back on until you manually replace the fuse. I would suspect that the problem lies in poor wiring. If it was wired a long time ago, the power/ground connections may have become rusted or corroded. Look at where your power wire connects to the battery, and where your ground wire connects to your chassis. 12V "light bulb" testers are crazy cheap if you want to test that the connections are good.
