Guys need help ASAP
11.8 cube box gross
57w x 28h x 15.75d
Going in the back of a f150 extended cab
Subs being used/ 2 15 fi bl
They need about 128sq of port area!
How long of a 6inch flared port will I need to get a 33hrz tunning?
I have about 55 inch to play with
Will I have enough port area for the subs?
Or should I go with one 12inch x 17 long sono tube from Home Depot?
