Got my 2 12" Memphis PR series subs and a Memphis PR100.4 amp, with the subs in a sealed box. Very very nice I must say. Especially since I got one woofer free and paid the 10" price. They hit nice and hard but don't take away from the music just adds to it, not like alot of other systems out there that just go BOOM as loud as possible while sounding like crap.
