I'm going to post 2 photos to show exactly what I mean
I initially was dead set on three 10s or three 12s for a standard cab blow through.This design was gonna bring the sub box flush to the front bed sealed against the accordian boot. And inset the subs into the cut out a few inches ... So I cut out and sealed in 10ft of Accordian boot and sealed it around edges with real polyurethane windshield caulk 13.5 H x 39across . Turned out wonderful.
I had "Ditched" the stock plastic rear cab panel and made a rear cab back panel from 1/2 mdf and vinyl wrapped it and cut out the same accordian boot dimensions.
Did not like the exact look of the panel or how it fit so I put correct formed "stock back panel in the truck .
Now where my dilemma stand !
I'll have an aero port squared box design with "two 12s going to be flushed and sealed up to the front of the bed into the original 13.5" Tall X 39" across opening with the drivers and port firing into the cab.
But now since I'm using my stock back panel inside cab Will I be ok with a smaller air inlet or a few of them cut out of the plastic to direct the box "Air flow" into the cab . Will any of this extra "accordian"opening behind the actual "interior panel be ok as sealed open dead space now that I've narrowed thinga down .
A very well known box builder online told me you want a blow through box to really be sealed to the cab wall or bed wall flush to allow all the air flow and sound into the cab VS just a ported box designed free floating anywhere in the bed with the bass and air flow traveling inside the bed.
I get the concept but I need to know how I should cut out the Stock interior back panel I know the hole don't have to be large at all seeing as the box will be sealed flush to the accordian cutout and still flow air into cab . Is this mainly just at will design however people choose to cut out the inlet for looks purpose?
