Mach System Speaker sizes

I am thinking about replacing my stock system in my mustang and i have a mach 460 sound system...what size are the speakers in my car ... i cant find that anywhere

the back is most likely 6x9, thats pretty standard on most cars

i forgot to say that i have a convertible
so the back one's i know arent 6x9's

Go here and check out the info.....BTW, if you do replace your 460 system, can I buy your Mach 460 front amp and wiring to use with the new Mach 460 Radio and CD player I just bought??? Need that to make it work in my 96 GT...

thx for the website and when i get some component speakers i will hit you up about the amp
