Common chamber port size ??

So basically the box will be an elongated version of this.

I'd personally lean more toward this design. It's not as long as your box but I prefer ports that don't split.

Yeah, that's it.

From the side mine will be shaped like a house on it's side so the back wont be flat but yeah basically the same.

I was not really thinking of a slotted port, tube port was stuck in my head, but slotted might be better. Thanks

You're needing a wedge box not rectangular. It's best to go with an aeroport.

Ah now I see the shape of the box. Does look like a house. That complicates things. I'd have to pull out some scratch paper and math it all. I'm sure someone with bb pro can model that for you. Might want to run a port on the side of the box instead of the face since it's long and would allow you to run an aero without worrying about bending it around corners.

Agreed with the side port.

Agreed with the side port.

This has me leaning back to separate boxes or chambers.

I already have two 3" Precision ports. I just found a calculator that said 7" would equal 35hz in a 1.7 cube box and that would fit on the front side.

Since this is a work van and the box is in the middle of the van i thought it would be best if the port was facing the same direction as the sub as oppose to on the ends or sides but i don't know.

Thanks for all the input.

seperate chambers, dual side firing. Works on a lot of trucks, should work on yours too.
