3. Subwoofer Location
The subwoofer res downward and is omnidirectional, placement is less critical than full-range speakers.
For the best results, place the subwoofer near a wall and near the full-range speakers if possible. It is
recommended that the subwoofer be within 10-15 feet of the full-range speakers. It can also be placed
under a deck or behind bushes if you prefer a stealthy install.
4. Subwoofer Installation
Once you have selected the location for your subwoofer, you are ready to start your install. Run 12-14 gauge
4-conductor outdoor-rated speaker wire from your amplier to the location you have chosen for your subwoofer. It will need to be buried or suspended so make sure you mark where it is in the ground for future
reference. Your subwoofer is designed to sit at on all four of its legs. If mounting on a deck or patio, it can
be fastened down by using the two key-hole slots in the bottom feet. To do this, simply measure the center
to center distance between the key-hole slots and install two mounting screws into the deck or patio, leaving
¼" of the screw exposed. Place the subwoofer feet on the screws and rotate clockwise until the subwoofer
is locked into the screw heads. For installation in a garden or ower bed, place the subwoofer on a at and
level surface It is recommended to place the subwoofer on pavers to prevent debris, mulch or weeds gathering under the subwoofer as foreign objects can cause poor performance and could damage the subwoofer.
Note: For anti-theft security and permanent placement,
the IOSUB2 has a built-in eyebolt that enables you to
anchor it to its location.

5. Wiring Your Subwoofer
Once you have you have installed your subwoofer you are ready to connect it to your amplier. Strip the
wire outer jackets back about 2" and strip each conductor back about ¼" to bare copper. See connection diagram below, locate the 4-conductor input cable and connect the left and right channels from your
amplier. Locate the 2-conductor left and right speaker output cables, connect your satellite speakers to
these cables.
6. Caring For Your Subwoofer
Outdoor speakers and subwoofers are designed to withstand outdoor environments, including incidental
exposure to water. They are not designed to be washed using a pressure washer or hose nozzle. If debris
accumulates on the housing of the speaker, use a damp sponge or cloth to remove it.
7. Troubleshooting
Should your subwoofer not work properly, check the following:
No sound from speakers or quiet/strange sound:
• Make certain you observed proper polarity for both inputs and outs on the subwoofer. Check the
connections at the back of the amplier, and then at the subwoofer
• Most stereo receivers have an A/B speaker selector switch. Make certain that this switch is in the
proper position, and that the proper audio source is selected.
• Mute feature or protection mode is activated. Check for short circuits in speaker wiring.
One speaker is playing while the other is not playing or plays quietly:
• Check the balance control on the receiver. Make sure it is centered.
• Loose connection at either the receiver or the speaker. Double check connections.
• Bad speaker cable. Replace suspect speaker cable.
Receiver cuts on and o:
• This could be caused by a short circuit between the positive and negative leads. Check the connections at the back of the receiver, and then at the speaker; make sure that no strands of wire
from one connector is touching the other connector
