So i have had my mustang for a few years, and my old AM radio isnt cutting it anymore. I am looking to get a new radio, speakers, amp (if needed) and i was planning on putting the speakers under the window behind the rear seat. I also would like to put the new receiver in the place of the old one, it has the ac under it, so i know i will have to do some minor modifications. Its a coupe btw. I would greatly appreciate any advise, tips, or anything. Andddd this is also my first post! Glad to be on the team.
