I'm planning on installing a small powered subwoofer (Sound Ordnance™ B-8PT) behind the passenger seat on the driver side. In most cases, I expect I will not have the seat folded down while driving.
Is the performance of the sub impacted by not having the seat folded down? I may be out of my mind, but intuitively, it seems like having the seat up would be blocking the sub. If there is some performance drop, roughly how much of a difference would it be?
