These have only been in the car for about two weeks. All the crossovers and wiring comes with them. I have decided I want to buy a 10" sub so I have no more use for these. I am asking $175 + shipping. I can also accept credit cards through my business.
Please email me with any questions or interests at Jraad1@comcast.net
