Port and sub firing direction

[ace_800 5,000+ posts]

So I plan on rebuilding my sub box for my GTO. I found somewhat of an idea of what I want to do but not sure how to have the sub and port firing. I can have the sub fire facing up or down and the port either firing rear or forward. Which would work better?

Here is what I am looking at doing, no 6x9's though only a 10" Massive Audio sub.

The sub will sit more to the right looking at it from back to front, with the Xtant amp mounted to the left. The box will not be as short on the sides to be able to mount the amp.

Is it not possible to try both and see which gives you the best results? I would think sub up port back would be the best choice but that’s just a educated guess.

Yeah if I could I'd face it rear with the port up but no room for the sub box to fit in the "shelf" in the back of the trunk with it as so.

Its just a ported box in the shelf. Right now I have it where the sub is firing down with the port facing the rear seat. Just going to change the box since I got a different amp. I don't know shit about IB
