Bass soundwaves are actually really long and have a high peak and low valley. The goal is to get the peak of the way to hit your ears. The way you have your sub facing will change the distance the sound waves have to travel to hit your ears, thus sometimes facing back is better, sometimes facing front is better. All depends on the car and the set-upDoes anybody know why everybody I see face their subs towards the rear of the car? This seems weird to me. Does it help move more air or something? Will it hurt to turn the box around?
