your specs on the woof said 4 ohm per voice coil the amp looks like it wants to see a 1ohm load. i've seen memphis amps that didn't work right at too high of an ohm load so try it at 1 ohm. that means run all 4 positives to the pos term of the amp then run all 4 negs to the amp neg. if that doesn't work try one of your friends woofs on your amp. also try reving the motor to about2500 rpms when you turn it up.
