My friend just got a bose acustimass 35 system, and added a velodyne 12" powered subwoofer to help out the bass. The problem is that the velodyne is hooked up to the line out of the bose, and it is always on. He wants to know if there is a way, or item that can match the volume of the lineout with the volume of the system? So that the sub goes up and down in volume with the system volume.
