Im gonna start calculating my box for my 3518s but I wanna know how skinny I can make the port. I want to do a wedge box to match the angle of my rear seats with the subs facing up and the port across the bottom of the box facing back in my MDX. is 5" x 30" too skinny? Any other ideas?

seems a bit small for that big of a box......any way to add like 40 inches? It'll most likely be fine at 150 inches tho

yeah I can make it 48 inches long if I wanted to, I've just heard that weird things happen if it gets too elongated

Are you using a software to design your box?

DD says 100 sq. inches per 3518, I should probably step it up a bit...

do atleast 120 per sub

that much?? Thats what they recommend for the 9500s. I would really like to move some air with this setup though:cool:

Id go as big as you can manage without it making your enclosure too big to fit...

All that is going to accomplish is needing to make the port length longer. As long as he keeps that Vent mach in the green he is good to go.

its already in the green though with only 100 sq. inches for 2 18s. Thats why I dont pay much attention to that.
