factory-upgrade 1987 sound
Hi, new member, no Mustang but have several Thunderbirds, and given the lack of those-specific resources and the cross-applicability in many areas, I hope this is ok. Want to upgrade 1987 with standard sound to either premium sound of same years or to newer factory components as anyone might suggest. I like the 80s premium sound (when working properly), and am currently attempting to swap that in (head, equalizer, trunk amp, door speakers), but there are seem to be some harness differences, such as for the equalizer.
Any advice or suggestions would be welcomed. Thanks
