[QUOTE="GCAdidas13, post: 982254, member: 557864"] I am designing a box for two avalanche drivers that I would like to submit for approval. I'm going for 7-7.5 cubes net for the pair and will be firing upwards. The port will be 37.5"wide and 1.625" tall, and somewhere around 40" long. The port has four bends in it. The port side veiw is like so: [IMG]http://img279.imageshack.us/img279/8704/untitled2pi.jpg[/IMG] The port opening will be situated near the very front of the trunk. The subwoofers will be firing upwards toward the trunk lid, and about 4" off the back of the trunk.
