Do the direction of the subs in a car matter??? Forward vs backward?

New member Username: Dusty11185Post Number: 2 Registered: Oct-05 | OK so i have a car that im going to put two 15's in. Im a bit confused on the best direction to have the subs face. Keep in mind i plan on having the subs in a sealed box, if that matters at all -Is it better to have them face away from the driver, towards the trunk.. If i built it that way, there would be a small gap between the top of the box and the top of the roof of the trunk, to let air pass though. - Or is it better to just face them toward the driver, considering they will be slightly tilted toward the roof, but for the most part, facing the front of the car? - or are there perks and downfalls to both??? |

You also get compression loading bye facing them towards the back of the trunk, this can be altered to an extent bye how far away from the back they are. In compression loading, the subs aren't just exciting the air directin in front of them, they're moving a big "pillow" of air behind them this tends to make them play louder. I say aim them towards the back, then if you get curious aim them foward, chances are you'll end up spinning them right back around. |

Post Number: 1375 Registered: May-05 | your explanation i think is the best brian. start facing towards the back, then switch them around until you're pleased. i did it with every box i had in my rodeo and always ended up rear-firing. couldn't have explained it more precisely. i just figured a thorough write up might be valuable for explanations and test results.. however, if you are having the box built permanently, i can understand. i can only speak from experience and concur with xman. facing up still sounds great (in my truck).  |
