Okay here's the setup.

98 Honda Civic

10" Kicker L7(2 ohm + 2 ohm) in a ported box powered by a Rockford Fosgate 451s bridged at 4 ohm (450 RMS).

Wired with 4 gauge power/ground.

All controlled by a Alpine 9805

The problem is that we're not getting hardly any sound out of the sub. I turned the gains all the way up and still not at a normal level. If we adjust the level on the head unit to subwoofer +15 it sounds at about the right level with the gains all the way up. If we put the gains at about 2/3 you can't hear hardly anything out of the sub. This is just very wrong.

Whats going on here? Help!
