Fresh redo of the audio

After a long break back to working on this project, still stuck with same setup (for now) but got it set up nicely.. least doors closed and windows up i can hear it inside the house plain as day XD. Thanks to all for the advice

my single cab mazda is setup for 2 12's currently. and i can cut the holes bigger to do 2 15's easy in the cab and still have tons of leg room.

you could also check out re audios slim subs, and powerbass slims. i heard jl's tw5 is the best slim sub and the re is pretty close but cheaper. havent heard any of them in person though.

Im liking the setup tucnrim showed. Since im stuck with a bench seat ill need something close to that to do with. can i possibly get the Dimensions on that build? got plenty of wood to mess with

The box is 1/2" at the top and 10" deep at the bottom. Is a wedge shape and contours to the rear wall and then sealed. Also it is 4 foot wide. Works for 12's and I am going to see on fitting 2 15's in this setup.

Thanks for those, Ill see what i can do. What you recommend sealing it with?
Im also thinking of trying to do it with some clear material, plexiglass or something.. got my eyes on a light kit and ill have 2 spare 9 inch lights to throw in the box.
