Yeah, after thinking about it longer...I doubt that they will sound that good without something to hit off of. They're firing down right now, and even if I were to put six of them(three on each side) back there (and while they are a tight sounding sub) I still doubt it would give me the best SQ(or have the range) I'm looking for.
Went to a different place in town to get my amp installed and talked to their "lead" installer (whose supposedly won alot of SQ competitions) and told him that I was looking at the "stealthbox" and he said that he could fiberglass a 'PORTED' custom box with a JL10w6 in it and even finish it in the cover of my choosing(carpet, vinyl, plastic, etc..) for roughly the same price. I would have to buy another amp though to power the 10w6.
SQ wise, this would give me the best sound possible...Don't you think ?
