I'm redoing some things on the system I built earlier this year. I've removed the Alpine amplifier that powered my rear fill.

No scratches.. works as advertised. Includes Original box as well.

PM me with questions. Price is $105 shipped to U.S. lower 48. All offers that equal $105 will be accepted - all others rejected. ;)
