Not sure, but it probably could fit there. I replaced all speakers and bass did not sound good to me possibly due to sub was old. Replacing sub with OEM newer would be pretty expensive without unknown sound quality results. Sound system now is really good. I supposed sound would be pretty good if its coming from under driver's seat, but I decided to do it more traditional way with sub in the back of the car.
Does that sub not fit under the seat? And the built in sub not enough to produce good bass? Does it improved a lot with the new 8inch sub?
