I had a buddy that had a triple MTX 10" setup, that was one of the first that I can remember hearing,(but that was like 16ish years ago. but even by then I had already gotten started with BASS in my own car before then, my brother had a bass tube in his 94 Silverado and we put a bigger sub in that truck till I started driving and put some cheap crap in my first truck, but I would say it was the Triple MTX setup that really inspired me to get better stuff.
and the CD that did it was Kilo Ali's "Organized Bass".
