Check the amplifier for... blown fuses, no ground, check the fuse by the battery, there are a lot of things to check.

All the fuses are good..umm.. the ground is still connected... for now I rewired the speakers to my deck...but its not nearly as good... :shakehead
Ill double check all that stuff in a bit..but im pretty sure its all good...
