Box design for 6- ID8's

[gixxer9 10+ year member]

Due to the space limitations under the back seat of my Silverado, I have been considering doing 6 ID 8's with 3 per box, and two being ported in each box. Would it be ok to have ported and sealed subs as long as they were all the same?

I'm thinking of firing the two ported subs forward (ports will be forward firing as well) and then a sealed one downfiring. The reason for this is the ported sub chambers need to be .6 ft^3 each, and the sealed need to be .35 ft^3 each.

What do you guys think?

Would it be better to do them all ported, with two forward firing, and one up firing? I could do all three ports forward firing..

I would personally do all sealed or all ported if you have the room, btw nice to see another wisconsinite on here.

And I'm still heavily medicated, lol! So my mind has been running wild..

I initially planned to do them all downfiring and ported, but now I think I might do them all up firing...

Do one or the other. Sealed for SQ, ported for more SPL...

Right. I'm going to do all ported, but what configuration would you do? All upfiring, all downfiring, mixture, etc...

The easiest for me would be upfiring, or upfiring and forward firing because I could do the floor out of fiberglass...

I dont really know what is best in a truck...I've seen upfiring,side firing, downfiring and foward firing... I think I've read subs up port to the side does well for SPL setups.
