My mustang came stock with the Mach 460 system with the 6 cd indash changer. I replaced it with the following:
Knu konceptz battery terminals and fuseholders
Alpine CDA-9855 head unit
Knu konceptz Interconnect Signal Cables
XM Direct tuner
Cadence Z8000 for the mids
CDT HD 65's
Adire Audio Koda 10" woofer
Directed Audio 250D for the sub
MTX Thunderform Sub enclosure
