JL Stealthbox system for your Mustang adds A LOT of bass to the stock system. I had this on my premium and it was one of the best sounding subs I've heard. Not overly obnoxious muddy sounding bass, punchy where you want it. It really rounds out the stock shaker stereo. See my thread for more...
Thanks for the positive feedback on the price guys! There's always gonna be tire kickers
The car came with the 3.31's, I wanted the 3.55's but the dealer didn't have a premium with them. They are a bit tall but with the tune the usable range is quite good.
