Alright guys, I have finally found and bought another truck and the stock radio ***** and must go ASAP!!!

Here is a rough drawing of the room I have behind the seat...

<- Front of truck

The box can be up to 60" wide from driver to pass side. Is it possible to build a 2.5cuft box and tune it to about 32-33 Hz? I have no clue how to calculate port dimensions, so Im pretty much at your mercy here :(

The mounting depth of the sub is only 6.5" I think, so I could prob just build a rectangular shapped box that is about 8" deep x 16" tall x ____" long. Really just need help when it comes to the port part of this.

Thanks in advance,

The sub Im trying to use is a RE SX12.

Can also PP some money if needed ;)

Here is a pic of a mega cab rear that may help out.

This is what I came up with using the box and port calc. on the12volt.com.

Could someone double check this for me though?

The over all height of the box is 16". Port height inside is 14.5". I just noticed I didnt put the 16" measurement on there.
