ARE YOU IN PHASE?
If your bass sounds weak or garbled when you hook it up as a 2 channel system, try using the balance control on the head.(all system speakers playing ) First, balance it left and note the output. Then balance it right and note the output again.
If the system sounded worse (meaning weak bass output) when centered or faded to one side VS the other, that sub is out of polarity with the rest of the system. Reverse the wires on that sub only and you should be good to go!
If running a MONO bridged amp and 2 or more subs, same idea… turn down the gain to the sub amp, disconnect all woofers. Now, connect 1 woofer and note the bass. Reverse the polarity and note the bass. The polarity that sounds fullest when the rest of the system is playing, is the correct choice. Now, match all woofers used with the known good one. All cones should move in the same direction at the same time. Readjust your gain to obtain the bass you desire. That’s it! If you got it right, now you have full, clean and unadulterated bass, in phase!
Enjoy the bass,
