I have a Klipsch KSW12 subwoofer, Im running it with a Yamaha RXV596. Line out to left and right input on the sub. My splitter broke, do I need to use the splitter. I only used it because it came with the monster sub hookup kit. My amp is set for bass output only thru my sub, setting is large in the amp for the mains. Any help would be appreciated.
