This sub is brand new (NOT refurbished, like most of the ones on eBay), never installed, never taken out of the box. I have the original receipt purchased from an authorized JL Audio dealer, so if any warranty work is needed, it shouldn't be a problem.
This sub is $259.99 on crutchfield, my price is only $150 picked up in Torrance, CA.
Specs are here on the JL site. Its 12w3v3-4.
