dealer son, or u can try try the post in the wtb section and see if anyone has one. or u can try to get a msp one if it fits right... not sure about the fitment though.
you can always buy another bazooka style sub if you want to make it look like stock again...but as far as the exact kenwood bazooka ur not gonna find...they still make them but ur gonna have to go w/a different model number is the only thing different about them i bet
