[QUOTE="Memnoch, post: 8867749, member: 690593"] Thank you that was super helpful. I am going to get my father in laws MM and measure the subs again, I am pretty sure that when the MM was connected to just one + and one - port on the sub that it was reading 2 OHMs with nothing else connected. I am redesigning the box as well (well resizing really) as I learned he wants to be able to put his center console up so someone can sit in the middle, and that drastically reduces the space behind the seats. There are also some sort of clips installed on the back wall throughout that add a bit of depth as well so I need to take that into consideration. I'll post the dimensions etc. when I am finished with it. I think it will still work, it comes out to around 3.62 cu ft with the modifications. I have a couple of questions though about the ports. The spec sheet had said 12" in length and 4.5" from the wall. The ones you suggested for this are 20", and neither those nor a 12" port would be 4.5" from the facing wall. With the 20" it would still be around 22" from the wall. Does that affect performance or air flow? The only other way to try and solve that if it does, would be to build the box taller and reduce the length but I don't know if that would be possible without blocking too much of the rear windshield. I meant to ask, would each port take up the .25 cu ft of air or was that for both? I assume the brace being open on both ends, and having the center hole would not take up much of the air space, but should the brace run fully along one of the front or back wall or is it fine just in the middle like I have it in the picture below? And finally, when building the walls, is there a particular order that would be better suited to put it together. The dimensions would change depending. Example. the top and bottom in the one I am working would be the outside pieces, and the current design has the front and sides on the inside of the top and bottom. Would it be better to put the front and back panels on the outside? I would assume it would be easier to mount the front panel last that way, but thought with them on the inside it would provide more structure stability for the bottom.
