The item is an 08L715. It is the dual 2ohm version and has been used less than 6 months. I picked it up when I used to be an installer at Circuit City. I made the box my self and it is included in the sale. This woofer sounds great and gets extremely loud! This sub is in excellent shape, Retail on woofers etc. is $349 and thats without the box. I hate to part with this sub but I need something that will fit under the seat again. Will negotiate.
