My System includes a Sony CDXC90 connected with a Rockford Fosgate 600a5 amp. The Amp is powering 2 sets of MB Quart 5 1/4 Q series in all the doors with an MB Quart midbass driver in the rear deck. Sound so good I don't need Subs. But I got them anyway. Two 15 inch MTX 7000's powered by 2 Rockford Fosgate 250a2 with a lightning cap. If anyone is going to the AFN in Carlisle this june 1st then you will get the chance to hear it and see it. I'm allready regestered to be in the show. See you all there.
