I will own a 05 mustang GT and want to put an aftermarket system in it. i want at least 1 12" sub in a sealed custom fitted box to not take up so much trunk space. i really dont know anything about amps and speakers. anyone with any type of knowledge would be great if you could let me know what i need to look for. i want my system to hit and be clear at high levels and also clear at mid volume levels. i'm going to be driving on Marine Corps Bases and i dont need my system to hit so hard that people can hear me over F-18s taking off. Any info would be great. thanks.

 

Check this out and if not that then look around the Crutchfields website for other stuff. Does you GT have the highend factory system & you just want to add more bass, or are looking for a complete system?

 

I got the stock system, not the shaker system knowing i would be replacing the speakers and putting an aftermarket system in. I will be putting in a complete system.
