You could always buy two since they aren't $2k anymore. I recently got a new in the box player, never installed for $350. Some people got extra's during the close-out sale.

I'm on my 4th HD. They seem to be the weak link. I think my problem is I sometimes start the car to move it a few feet and then shut off the car before the empeg fully boots. That's probably not too good for the HD.
