Hello, I thought I would try this again. We had an 05 V6 that had the shaker 500. Not the best, but it sounded Ok came with the car. We recently traded for an 06 GT, however no premium sound was available in the color my wife wanted. With those two subs in the doors of the 05 we traded, the overall sound sustained pretty well with the top down. We want to put in something better, with ipod hookup, better head unit, but the issue is what to do for speakers since the space is limited. Anyone have any experience with premier shallow mount 8 inch subs? any ideas would be welcome if anyone has improved on factory convertibles??
