I have 2001 F150 SuperCrew. Currently I have a 12" in a .78 cuft sealed box. But I want to use a different 12 in a band pass box where my spare tire rides, and run a port from the box under the bed to just behind the rear seat.
There are several reason I want to do this, mostly it's cabin space restrictions.
So from the front of the box to where it would enter the cab is roughly 4 feet. Can I run a large port to keep the tuning around 30Hz? Maybe two 3" ports?
