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?

11.8 cubic feet will require a 6'' port 2'' long according to Win ISD. Might consider the 12'' sonotube at 16'' long for that tuning and to allow for decent port area. A single 6'' port is not enough area for the sub and when you move to multiple ports, the lengths start increasing.

A single 6" is to small on port area. Increasing port area will net a far better result.

What ever program you are using for calculations is rather off though as already stated.
