i just got an 03 gt with the mach 1000 system. just wondering if switching out the subs in the trunk would do anything for sound. if anybody has done this or knows about can you give me some input. thanks for your help

 

i have thought the same things because i am looking at a 03 GT w/ mach 1000 in it and while i drove it i cranked the steroe and turned up the bass and the plasic mach boxes seemed to resonate alot, you could defentanly get better subs than that but i dont know if the box could handle it
