Hello all,

First post here, so be kind to an old-schooler...

Looking to do a bed box in my Chev 1500 step side. Max dimensions I've got are:

Width = 48

Height = 18

Depth = variable

I'd like to go with 2 BTL 12's, dual 1ohm.

Both subs will be powered by a RF T2500.

Wondering if one of you fine gentleman would point me in the right direction with:

Net Vb for common chamber enclosure... 2.65 cu.ft. per sub?

Optimum vent dimensions based on a 16.5" vent height?

Hopefully I provided enough info...

I certainly don't expect a full design, maybe just some guidance.

Thanks guys,

C

Did some sketching in Solidworks...

Does this look like it should do ok?

Will I have issues with the common chamber?

Thanks all

Looks great!

I think this revision will be a bit better for my truck. What do you guys think?

Subwoofer placement, distances from vents, etc?

Thanks again all

I like the revision!

Go with the revision but take out the middle divider and keep the (2) 45 degree pieces.

Better to run a common chamber as you gain max port area.

what year chevy you got ?? those cut thrus are tough (stepsides 1999-04s).
