A late 70s car stereo will be either a discrete transistor amplifier biased as close as humanly possible to class B, or an early IC power op amp. It's not a miniaturized Harmon kardon citation, it has more in common with a transistor table radio. Of course it can sound good, and of course quad 8 track is really neat... I only said why I went modern because time is finite and driving two hours every day without a properly working radio is really boring! Given unlimited time, my car would have a nakamichi 350 or an early 80s pioneer setup
