Do the two little compartments in the F30 trunk meet the minimum volume requirements that are optimal for those subs? Looks fantastic btw - wish i knew how to work with fibreglass and where to get the materials....
You wouldn't want to build/sell another one would you?
... or write up a detailed DIY ...
EDIT: Never mind .. lol - did a little more digging and noticed your 8W3v3's are only rated at only 250W
looks nice, but need something that will kick some serious ASS. And at 0.30 cu ft minimum JL audio recommends for sealed box, you are lucky to get the min volume you need for those things in those tiny little F30 cubby holes. Next.
