Mach 460?

[Swede2]

Hi
I have a 1997 GT convertible with something that I think is a Mach 460 sound system. There is a FM/AM/cassette player and a CD player that are definitely Mach 460, but there are only four speakers. Two in the lower front part of the doors and two in the side panels beside the back seat. I can not find any tweeters. What system is this?

Sounds like a standard system. How do you know the decks are mach? I think the decks might be the same from the standard and mach, just the decks in the mach system might say mach on them. The difference in the systems is the tweeters and amplifiers under the rear package tray.
