Im sure this is gonna sound like a retarded question..but a few weeks ago i bought a sub and amp, and it sounded really good hit hard, then i got in a wreck about a week later not too bad just messed up the passenger side of my car....well i got my car back yesterday and rehooked my sub up and now it just doesent bump at all compared to what it was doing..nebody have any ideas on y it would only be hitting at about 1/2 of the power it was hitting at? i know the popped my dash off for some reason so maybe something came loose ? i dunno any help/ideas would be appreciated

I'm sure you already now this but, Check all the connections on the amp and behind the dash. Maybe its not gettting full signal
