SPEAKER INSTALLATION
(continued)
• Each Boomtomb Sub has a two-conductor cable exiting the enclosure. This cable should be connected to a similar
cable run to the speaker location from your audio system. SpeakerCraft recommends using certified direct burial cable
that is ideal for this purpose. CAUTION: Use only one speaker lead when connecting to the Bass Power 250 amplifier.
Using both leads with the Bass Power 250 may result in system damage. If using any stereo amplifier in place of the Bass
Power 250 (part #AMPX67250), use one speaker lead for the left channel and the other for the right channel.
• When attaching the wire to the Boomtomb, it is critical that a high quality connection is achieved. A poor
connection may lead to corrosion and a decline in or loss of performance. For best results, use a set of weatherproof
wirenuts. Another option is to use a watertight direct burial box or crimp or solder the wires together and use a heat shrink
tube to seal each connector.
AMPLIFIER PLACEMENT
DO:
• Place the amplifier with the feet resting on a solid flat level surface.
• Place the amplifier in a well-vented area to provide proper cooling. In areas that lack proper ventilation, such
as tight cabinets or racks, it may be necessary to install small fans to create air movement.
DON’T:
• Don’t block the ventilation holes on the top or bottom of the amplifier. Never place it on carpeting or similar
material.
• Don’t place the amplifier in any other position other than horizontal with the feet down. Never place on its side
or resting on the back where the terminals are located.
• Don’t place the amplifier near heat sources, or in an area that it would be exposed to moisture or excessive
humidity.
YOU SHOULD KNOW
• The power supply may cause a hum to be heard in some components if they are placed very close to the
amplifier.
