I didn't know people still did car systems. That was a huge thing in the 80's and hit it's peak in the 90's. My older brother had a killer system in the '92 era. Nowadays, I hear maybe 1 person every few months bumping and it's usually the same person, but now it drives me crazy...haha. It's just not a cool thing anymore like it was in the day. Kind of like the old school tight rolling of the jeans era, hydraulics, and skateboarding the wheels times. Man, it's crazy how fads can go from clothes to our vehicles as well.
