I'm going to be installing a set of Crystal SSCS 6 components in my Mazda Protoge' 5 this weekend. I most likely won't have rear fill hooked up at all, and I will be running a single 12" Alpine SWS 1222D sub in a sealed box. I've got two amps I'm deciding between.....an Alpine MRD F752 T Class 5 channel: with this one, I'd bridge channels 1-4 to give the Crystals 200W RMS a side, and the sub 300 RMS. The other amp I've got is a old Soundstream Reference 644S 4 channel, which would do 75-90W RMS to each front, and bridged it should do 150W RMS to the sub. I listen to mostly hard rock, with a little techno and rap thrown in once in a blue moon. I like my music loud and powerful, but clear. Any suggestions??
