I have a Alpine MRP-M450 Mono Amplifier and a 12' Rockford Fosgate HE2 sub woofer sealed in a ported box with plexi glass window. I will include the two wires which are pictured in the pictures, not really sure what their called. This setup was rarely used because most of the time it was sitting in my room not in my trunk. Also the amplifier has a warranty with Best Buy that ends in September 2011 which I am also including. I am asking $275 for this set up, the amp alone was $250 so I am basically selling the the sub for $15. Please get this out of my hands I have no need for it.
