Did you want a slot port, or pvc pipes? or if you wanted you could just build it to Alpine specs. Here a link to the owners manual just in case you didn't have it http://www.alpine-usa.com/images/products/documents/OM_SWR-1242D.pdf |

Silver Member Username: Seth_walkerU.S.A. Post Number: 179 Registered: Jul-05 | Here's something you might consider it's 2 cu. ft. w/ 39 sq. in. of port tuned to ~34.3hz. Oh and the width of the box (the side you cant see in the pic) is 14.5". the port is 13x3. everything is 3/4" mdf. You would mount the sub on that top sheet (although either of the sides would also work). |
