Wussup yall, this is my first time posting in this site..I was wondering If any of you guys know how I could mount some 10' subs without a box and still get some bass...I heard that there was something like a free air sub..i don't know if that exists or not..but the guy at sound advice told me that its just the way you mount it..If anyone can help me out send me and email or reply to this....thanks
