I have a 94 gt convertible, it used to have a mach 460 sound system but the guy stripped everything and put a headunit in and took his old speakers, what size speakers do i need to replace the car with? Thanks.
go to crutchfield.com, that will tell you what you can fit in the stock holes. You can also order any other size speaker from them and they will send you free adaptors to make them fit.
