My brother got an SA-8 and may not be able to port the box based upon where he wants to put the sub in his truck. If he decides to go with sealed, what volume should the enclosure be built to ensure the maximum quality output? Thanks in advance for the feedback.

You're really going to lack low-end if you run it sealed...I'd try my best to port it.

I agree with Ryan tho. I listened to mine in a small sealed box once and it wasn't that great. You would be better off with the e8 for sealed. It isn't terrible until you hear the difference with it ported.

Sealed spec is around 0.25 or so -- but is not the best setup for our 8s.

I just went from a .3 sealed box to a ~.63 ported box and its was a very very noticable change.

Mine went from barely hearing it in back of the car to my wife noticing when I get home.

Don't even bother with it sealed, it kills a lot of the potential the SA-8 has.

I thought that was for the E8. I stand corrected on that.

Either way, I still stand behind all the statements of going ported.

Thanks for the feedback. I'll attempt to go vented if at all possible.
