Here is the issue. I have an 18ft Spectre that had 2 12in orions in boxes under the bow. One box was broke so i took the sub and put it in my girlfriends car. The other i hooked up and it sounded like shit. I checked the box and found that their are air leaks everywhere! I just got 2 jl 12's that my girlfried bought for the boat (not sure what model she got them at a garage sale but she hooked them up and said they work) so i would like to install them next time i go to AZ. I would have 1 nite to do the install and im not sure that even if i got truck boxes that they would fit through the access hole for under the bow. I dont want to build them under the bow i would preffer to build the then slide them in. Does anyone sale premade boxes that fold together and use a couple of screws in one location that would sound good or do i just bite the bullet?
