Well Ive had my system in for a few months now and not totally satisfied...I am running a PDX 4.150 with a set of SPR-17s Comps up front and Type R 6x9 Coaxs in rear...It sounds pretty good to me, Im not a huge sq guy and Ill admit I dont have that picky of an ear but I just want something that might be able to handle this amp better and get louder, I was wondering how the SPX-17PRO setup would be? the Type R 6x9 coaxs are about as big as I can go in the rear, due to the factory locations, otherwise id be swapping in a set of REVs...
