Hi Korky,

I would suggest double checking the wiring of everything, it is easy for something to get crossed. Especially check the speaker wire phase to each woofer section; follow the copper colored wire to ensure it goes from the positive on the amp to the positive on the speaker for each woofer section. One woofer section wired out-of-phase will sound thin. If you could e-mail me some pictures that would be great too.
