Did you get the impedence right? If you hooked up an amp thats 2 ohms per channel into 4 ohms woofers that could be your problem! Under this circumstance BARBEQUE!
I have my two subs bridged right now, it was working fine, should I unbridge them..?
Oh, and I do believe I found the problem..The Inline fuse was dead..Deader than dead..Well it was pretty melted..I just ordered some more 80amp fuses they won't be here untill tomarrow or tuesday.
