6 cubic foot ported box in the back of my 01 Jeep...Wondering about the size of my port and anything else that could help me. And also I was thinking about having a few circular ports...?

Thanks for any help.

How much room do you have to work with? exact measurement would help.

height= 1.5 feet

Width= 3feet

Lenght...as much as it needs to

Length is 2.25ft

What amp do you have to power the 18? Do have a tunning choice. That sub is recommended for a 28hz box. Do you need it a little higher.

I've never seen anybody measure in ft before

build the box with the dimensions you have:

36 (L) x 28 (W) x 18 (H)

slot port:

5.5 (W) x 16.5 (H) x 42.75 (L)

Ends up being:

6.1ft^3 @ 28.05Hz

I'll suggest sub up, port back

seems to work very well for hatch style vehicles

sub up port back

Here is a quick sketch of maybe what you are looking for. The box is tuned to 32hz. The 3 round ports are 6inch by 16.75L. You said you were looking at maybe round ports.

Good luck!

wow thanks for the sketch. Im gonna get the FiQ 18" D1 with an AQ2200 (2ohm) hows that sound to you guys?

btw what the best free program for sub enclosures?

What tunning do you want for you box?
