Before I sell these elsewhere, thought I would give you guys a chance at them. I have 2 - JL 8w7's anniversry editions. Brand new, never mounted, in factory cardboard boxes ready to ship. These subs are the perfect sub. Sound quality and output, and they only need .75 cu ft. These are great for the xfire due to that size. AVS priority makes a great box for not alot of money that I would recommend for them (fits xfire perfect) or you can go custom. I paid $800 for them, steal of a deal for you guys on the forum $500 plus shipping.......
