are you looking at the sa 8s or the sd 8. Reason I ask, i thought the SD8 were meant for sealed. I thought sundown was pretty clear that they can be ported, but it was not recommended as they are for sealed.
Its been years since I heard anybody using these. Back on DIYMobile a few guys got them from a clearance spot and I think most said they sounded best in larged sealed or 4th orders. Again this is from memory. Not saying it wont sound good or work, i just dont remember any running ported back then. You many want to do a search there to see what pulls up from the guys that played with them.
what kind of cloth and resin did you use to do those ball in the A pillar? I may try to copy that do mine, loved how yours turned out for the mid and tweet. It looks like you just taped and covered styrofoam balls that you find in a craft store?
