hello i have an 03 gt with the mach system. what size speakers do i have in the front and back?
thanks

 

Fronts are 5.5"x7.5" and the tweeters are 2.5". The rear are 5.5"x7.5" also. Verts are 5.5" rounds in the rear.

 

that is 5 x 7 front and rear and the tweets are 2.5's. You can fit a 6.5 in the opening if you make a baffle.

if you are replacing the mach woofers you will need to replace your deck if you have not already. The mach system uses some funny impedences to make it difficult

 

when i bought my car it came with the jl audio stealth box and a jl 250wt mono amp. i bought a avic-z2 (on it's way) and i'm looking into focal speakers and a jl 4 channel amp to run the speakers but i haven't decided yet what size to get. more than likely i'll have them installed cause i need an amp rack made. i plan on hiding the new tweets inside the mach tweet housing to keep it stock lookn
