I have a 272 and over this past summer I installed two 10' subwoofers under the bench seat. I didn't build an enclosure for them though I just made the whole on the fiberglass bench and mounted the subs on there with a backing plate and used basically the bench seat as its enclosed box. Sounded ok but I think it can sound better if I build a box for both subs. I wanted to get some ideas as to how some people have done it on here with with similar bajas and was wondering if anyone had pictures?

Been a while scince i have been into loud music but way back when i believe subs needed a certain square footage for enclousers per sub

Free air subs so you can still use the space under the seat.

I built two separate boxes not touching the floor out of 3/4 ply wood and treated it with sealer put 4 10" speakers under back seat looks great

Mine came with two free air 10" subwoofers. Sounds ok, but not much bass. When I can I will build sealed boxes and swap out the subs.

I've been running 10 inch Bazooka tubes the last year and they have held up well. Got them off ebay.

All your speakers are crooked

Yeah, I just noticed that too... bummer...

Yeh I complained about that and it is being fixed when I add some more this winter. I have not had time to fiddle with anything.
