What port and sub direction should be the loudest for a DC Level 5 15" in the back seat of a 2012 Dodge Ram? The box will be sitting on a platform that folds down under the back seat. And can someone help with dimensions of a box, please? The max dims are 18" tall, 18" wide, and 35" long. Thanks
Here's a couple of pics if you can't figure out what the box will be setting on
