The modern stereo system

My “modern” stereo system consists on a pair of 6x9’s located in what would normally be the rear doors in an early A wagon, a pair of 4 inch midranges mounted in a modified early A dash center speaker bracket snd a pair of 2 inch tweeters mounted at the outboard ends of the dash. Used early 70’s B Body speaker grilles there. The radio is a simple AM/FM/Sirius unit. Can’t remember if it has a CD player. Figured that was enough and Called it good
