Bed box for 2 BTL 12

[kevlar129bp 0]

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

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

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.
