probably coming from another component.

Hum can also be caused by AC ground loops. If the Subwoofer is plugged into a separate AC outlet, try plugging it into the same outlet used for your amplifier or receiver, or reverse the polarity of its AC plug. If these suggestions do not solve your problems, contact your dealer or M&K.

6.If there is an unusual sound coming from the Subwoofer with no music playing:

Try removing the input cables as described in Step 5 above. If the noise disappears, it is coming from another component. If it does not go away, contact your M&K dealer or the factory.

IF YOU NEED TO REPLACE THE EXTERNAL FUSE:

Disconnect supply cord before changing fuse. Replace fuse only with same type. Remove the fuse cap by pushing it in while turning it in the direction of the arrow. Look carefully at the fuse. If the wire filament inside the glass is broken, replace the fuse ONLY with one of the identical size and value. Using a larger fuse will void your warranty AND MAY CREATE A FIRE HAZARD. Plug the Subwoofer back in and try again. If it does not work, unplug it immediately, and contact your M&K dealer or the factory for service.

REPLACEMENT FUSE VALUES

Replace only with same type 3AG-250 VAC SLO-BLO 1 1/4" x 1/4" fuse.
