whats a good system set-up for the 99+ GT's? my friend has a 10 inch rockford fosgate with a Audiobahn amp and it is sooooooo loud. i mean you wouldn't think it was sumpin' special cuz' its only one sub but you can hear him coming from a mile away. it has to do with the custom box he built for it and how he has it set up i think but i was wondering what you guys have. his is in his SS so i was wondering whats good fitment for the Stangs.

 

an 8 inch sub would be loud in a SS, its a hatchback. For the mustangs if you want loud bass you pretty much have to go with expensive 10's or 12's for the trunk.
