[QUOTE="sforget, post: 58446, member: 544093"] I had this problem once. I'm guessing each amp is running a different sub in one box. If this is the case check your polarity on the speaker wires. You'll probably find that you accidentally got one backwards. this would one sub to pull in while the other is pushing out, effectively cancelling eachother out. [/QUOTE]
