BTL 18 Box Plans

[luckydogg72 0]

Would be grateful for any help. I just got my 18 btl in the mail and would like to start to build a box. I have built alot of sealed boxes but haven't built a ported box. I drive a 98 tahoe so size is not a problem. It will be used in a daily setup would like to tune that way but get loud thanks for any help

How about 49" wide (perfect fit) x 20" tall x 20" deep. Port will be 18.5" tall x 5.5" wide. Sub and port facing rearward. It works great. had a setup very close to this in my suburban with a RE XXX 18.

Sorry, the box shoudl be 20" deep. I was thinking about the box designs I did for the Q 12's today.

49" x 20" x 20" makes for 7 ft^3 tuned to 32 Hz with a little over 100 in^2 of port.

Here is a new design with the sub and port rearward. I experimented with my suburban and liked the sub rearward. To me it sounded better playing music. . .If you want the sub to be on top, let me know and I will make a couple of quick changes to move it to the top.
