you can get 8" or 10" subs here but for 12" subs you'll have to custom make them...
hey buddy me n my couasin actually made those boxes... they were a pain in the ass to make i tell ya.... everyon in town told me that i would not be able to fit 2 12" subs under the seat and we said screw ya'll n built our own lol i have an amp thats too big and not quite enough air space in my boxes for the subs that i have but if i dont push them to their max they sound FANTASTIC! dont get me wrong i still have a lot of bump with them! Overall im glad i did the 12"!!! if you want the specs to build them let me know! you can get a box to fit 2 10" or 8" though if you dont want to make your own...
i thought they went 5.3 6.0 and 6.5.... 6.3?
i send you a message. rough country 2 inch level lift.
you got a nice truck to start with... just have fun and take your time on the mods and do the ones that you like!
