Yeah sounds like you got it set fairly good. Seeing as there getting lots of power I'd personally run input voltage to half. Set it o low pass filter. Set low level frequency to 32hz to suit the box then change your high level frequencies to suit your taste in bass. Ie:80hz if you prefere deep bass or 150-200hz if you like the higher stuff too. But don't exceed what the coils can produce, I learnt that the hard way.. Ohh another 50 hz shouldn't hurt. Nek Minnit: giant paperweight
