I have a the "simple" bass engine on my alpine system. I set them all to flat with the bass at 100hz (200 is to high, keep it at 100) and the Q set at 4 (max) treble set at 10khz. The Q needs to be kept at max or you may have wierd peaks in your response.
It cuts out at volume 22 anyway, so I really dont bother with the eq.
