POWERED SUBWOOFER
If multiple subwoofers are used, try to place them in the same location. Stacking is best, but you can also put them side by side. Alternately, you can put multiple subwoofers in different locations, at adjacent corners. This is appropriate when you have limited choices in locating the subwoofer and none of the available locations work well. Try to place multiple subwoofers at equal distances from the listening position to avoid phase cancellation.
Wiring with two subwoofers is simple. By using M&K’s

9.HOME THEATRE USAGE
Compared to music sources, in some cases, you may prefer the subwoofer set to a higher playback level for video sources. This may occur when video sources (especially older films and some television) have very little deep bass present. You may also want to exaggerate the effect to make spectacular video sources even more impressive!
If you are using your Subwoofer in a multichannel Home Theatre system, make sure you are using the Subwoofer Output jack to connect your subwoofer.
CONNECTING THE SUBWOOFER TO A SURROUND SOUND RECEIVER OR PROCESSOR:
The preferred connection from a surround sound amp or controller is from a SUBWOOFER OUTPUT (or MONO) RCA jack. This connection insures that a full bass signal is fed to the subwoofer. If your component doesn't have a subwoofer output jack, connect the Subwoofer to the front Left and Right channel speaker outputs (do not use the Center channel speaker output).
IF YOU ARE CONNECTING YOUR SUBWOOFER TO AMPLIFIER OUTPUTS: When the subwoofer is connected to the Left and Right amplifier outputs using speaker wires, the Center channel WIDE/NORMAL switch MUST be set to the NORMAL mode. If the switch is set to the WIDE mode, the bass content of the Center channel will not be fed to the subwoofer, and a significant amount of the bass in the material you are listening to will be lost.
