idk how that car's inside is made up but couldn't just a reg slot port box fit upwards in there (according 2 his diagram) without need 4 that funky extension port area thing ???....
Back online... I cant fit a reg slot ported box in there because it'd only be 'bout 3 cubes TOPs and then it's have to be sealed cause port area is gonna take a bit... I am looking for this box to be dual chambered and 3.5 cuft per chamber... Gonna be tuned to 28hz... Can't wait.
