as far as i know, nobody stocks or sells replacement cases for this amplifier, your best bet would be to search for a good dead one on ebay or somewhere similar... failing that, you can take the case apart and use an aluminum or metal paint to repaint it after sanding it. the reason for using a metal paint is that most regular paints will have an unwanted insulating effect and not allow the case to perform its intended purpose, giant heatsink. you can also try to use metal polishes or an extremely fine grit sand paper (1000-2000 grit) to remove any scuffs and polish it at the same time, but this will remove any factory paint. i believe krylon or one of the other brands makes a metal tint paint that is translucent, i have used it to color match amps to cars and it seems to work well. it can be found at just about any napa or other automotive shop and i believe it is intended for wheels, bumpers, etc.
hope this helps,

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-
