whom-ever told you that you couldn't add a sub to the factory mach 460 system isn't very knowledgable in this feild. one option is to add a powered sub (ie. bazooka) mtx and infinity also make units. all you have to do is run a power wire from the battery and a remote turn-on wire (14-16awg) from the fuse box. (close to the hood release) be sure to connect the wire to a "switched" fuse (power when you turn the key) there is a grommet with a bundle of wires in the firewall close to the brakelines (driver side) poke a hole in it with a screwdriver. find the input side of the amps and connect a line level converter if you use an amp that requires rca inputs. *amp kits have everything you need to hook up an amp including fuses witch should be inline no more than a foot from the battery. i hope this helps.
