if some one had 2 18s in an explorer that hit 150db on 34hz and some one had a single cab chevy with 6 15s that hits low bass 150db at 26hz, which bass would travel the furthest from the car. and why. cause if you watch jacks chevy in videos you can just hear all the flexing from his truck, and in the exploer videos it sounds like you can hear the bass more,
