Thanks Joe. I really enjoy using sketchup and am slowly getting more proficient with it.

would i need to brace the inside or do anything like that also? just wondering but im not sure cause im really not running that much power so im not sure if ill need to do anything like that

I don't think you need any bracing on a single 600W sub, at least the way it installs in that box, if you add asecond baffle layer behind the external one arguably you would have less flex, tuning would go upwards a bit.

also would it be better to make a box thats sub up port back or does it not matter performance wise?

It's best having the port in the same surface as the subs, you can try aiming the firing up, back and front to see how do you like it better. In separate chamber trunks usually front firing is best, also you should let the port have some breathing room in front of it, best two times it's width.
