I have an 12'' Fi Q coming soon and i needed a box and i dont have time to do one myself so i went to the local audio shop to ask him what would be the best option. The owner actually held the loudest street car for two years in a row fyi....but I drive an f150 and i have a spilt rear seat. I wanted to take out the smaller section and have the box in that area so it wouldnt take up room for my passengers. His plans for my box is to have the sub face the floor of my truck as well as the port facing the floor. It will eventually exit out the side (meaning the port). He says that it will have the right cubes and hz. He says that when the sub faces down, it will shorten the wave which will make it sounds better in my truck.... I have never heard of this before but he really sounds like he knows what he is talking about. Help me out here, is he BSing? *sorry if it is hard to understand, its hard to describe especially since i have never heard of this *
