At the very least 2 6in aeros. Tuning is dependent on personal preference

so 2 6 in aeros wont have port noise?

It could, thats about the lowest you could get away with for 8 cubes. 3 would be more ideal, or even 2 8in aeros if you can fit them. Might be hard tho. I didnt consider that your box was 8cubes

So it Will be louder to the side than to the back...i was thinking about just doing a square port to the rear

If you are doing SUB UP.....you will prob get a better response with port out the side.....
