Ok Stem, I have no idea what that was for... well, i guess I answered my own question, Morel's SW10 is rated to 15.... now if they would just mention a sealed enclosure volume needed that would help!
Yes, yes it is //content.invisioncic.com/y282845/emoticons/wink.gif.608e3ea05f1a9f98611af0861652f8fb.gif ... Hmm... perhaps I should get a hand help RTA, and listen to some subs (in car)...
Not that hard to do with a sealed enclosure in-car. Cabin gain is your friend.
