double check my box design?

[bvr_j_0969 10+ year member]

if anyone would want to double check my box design i would greatly appreciate it.

i figured the port on the grounds of

10 cft for the subs

.64 sub displacement

.05 for braces.

10.69 cft net.

i got 2.48 port displacement

wich says my box needs to be 13.17 cft gross.

my box is 13.29 that leaves me with .12 cft for more braces/ wires

i would like you to check box volume, port displacement, and tuning.

this is for a wall in an ext cab sonoma with 4 re SR 15's
