This is a box plan that I have. I’m not sure if it will work or not but this is the type of box that I want to put in my car. It will contain two 15” DVC 2ohm Orion H2’s. It will have three ports for each enclosure and will have two enclosures. The four ports on the top of the box will be going to a customized rear deck that I will be making and the two ports on the back of the box will be directed into the back seat. I was trying to figure out a way to direct the two ports on the back of the box into the compartment in the back seat where the arm rest folds up and down. I haven’t figured a way to get both the ports to the same exact location because the ports are so far apart and in separate enclosures. If anybody has ideas or concerns please feel free to speak that is exactly why I’m posting this. I want to hear what all of you have to say. Thanks for the help.

First of all, is that box built to the suggested air space? And are those ports the proper length for the enclosure?

Yes to both dwarren I know the pic isnt in the exact porportions but when I do build the box the ports and the box will be the recomended sizes.

4 round ports...hmmmm Honestly I think it is going to sound like poop. I understand you have a sealed trunk. There is no need to port through the rear window deck and through the seat. I know a guy who spent months to try and get this right, In the end all he did was incorperate port noise and distortion into his cab. I would just recommend building a properly ported and tuned box facing the rear of the trunk of facing up towards the rear of the trunk.
