SWS subs ARE boomy and lacking in midbass. We m,ake certain to let everyone know that before purchase. I don't think your amp has enough power to force an SWS woofer to play midbass, honestly. I couldn't get much out of them with 100x2 of Zapco DSP amp (with 10 parametric bands of EQ). I switched my own car to Jehnerts and prefer them, but I don't listen to rap/hip-hop or much techno.
I would try lowering the bass control a bit below center and then boosting 100 in the EQ a couple clicks above center.
