My girlfriend eventually wants a system in her vehicle. Nothing really loud or anything, just a bit more bass then stock and inexpensive. I showed her the E8 and she thought a small sub was "cute" and wants one. The small box would leave space in the trunk as well.
I plan on building the box for her, but I must be retarded. The recommendations for the box are 0.60 ft^3 tuned to 30 Hz ported. I've been messing around with the calculator on RE's site and can't figure out how I would tune it that low in such a small box. The only way I was able to do it is if I make the port only 0.5" wide, which sounds way too skinny for me.
