5. Use the provided loop-through terminals (see graphic below). When this wiring method is used, you
should be aware that when a subwoofer is not plugged in there is no path to subsequent subwoofers.
An alternative is to wire incoming and outgoing cables in parallel. Pin 2 is + and Pin 3 is -.

6. Insert the pre-wired Euroblock connector, ensuring the correct polarity is being used.
7. Begin to insert subwoofer into the "C" shaped subwoofer mounting bracket. Make sure to connect the
snap hook to the safety hook on the back of the subwoofer. When the subwoofer is flush with the
ceiling leaving only the black magnetic brim exposed, begin to tighten the 4 attachment screws which
are connected to the mounting tabs (see graphics below). The screws will automatically turn once you
begin rotating the screw clockwise. Repeat for all 4 tabs and make sure not to overtighten the screws.
Note: Before you put the subwoofer into the ceiling, make sure all attachment screws are turned completely
counter-clockwise so that the mounting tabs are touching the side of the steel backcan.
Note: Make sure to position the subwoofer so that the mounting tabs do not sit above the opening in the
"C" shaped subwoofer mounting bracket.
8. Use a flat-head screwdriver to rotate the Tap Selector so that the correct power setting is adjacent to
the arrow. Note that there are separate 70V and 100V scales, depending on the line voltage being
used (see the graphic below). The transformer may also be bypassed by selecting the 8 ohm position.
It may be best to leave the grill off until setting the power is complete in case adjustments are needed.
9. Attach the magnetic grill on the subwoofer.
