[QUOTE="blazian87, post: 8521318, member: 574798"] From what I've seen online, most people run their SA-8's ported rather than sealed. That space is rly tight so going sealed might be the only way to salvage that box. Going flared helps a ton when going ported. I run a 4" flared precision port on my 4 10's. My port area is too small for my box too but I pretty much got away with it by going with flared. The way they calculate it is just adding like another 1" to the whole port length. The problem is the overall diameter is much larger so it still might not fit in your application. Don't rely completely on winisd. If you can't get the tune you want, you might as well seal it or go with a different setup all together. Here's the calculator for the flared precision ports to get a better idea..
