The problem is that the driver circuit is also damaged. Try powering up the unit with the output transistors disconnected. Measure each pad and report the results here. You should see something like 0.6,B+,0.0 on each set of three. Some will be negative rather than + (-0.6,B-, 0.0).
Keep us posted.

Hi Big Nick,
Sounds like you have got almost all the good out of those Subs. You can find the screws you need at almost any hardware store or Auto parts store. The light is becase you are dloading the amp with low OHMS. You may need use one channel and Run the wiring like written blow to get the power problem to disappear.
S1+ = Kicker comp cvr sub coil 1 positive
A+ = Amplifier Positive output.
A+ to S1+
S1- to S2+
S2- to A-
