Subwoofer Installation
70 volt audio systems allow for speakers to be daisy chained
together. In a typical system with one zone of audio you simply run a
stereo or 4 conductor wire from the amplifier to the closest speaker.
Once you have designated your first speaker as either left or right,
continue alternating the wires between the left and right channels
creating a daisy chain of stereo satellites. The Subwoofer can be
wired anywhere in the chain. See Figure 5
1. Find the best location to compliment your other speakers.
2. Decide which channel the subwoofer will go on, calculate load.
See wattage calculator.
3. Connect to amplifier wiring using the supplied wire nuts, see

note: sonance strongly recommends the use of 14 gauge, or
larger, direct burial grade wire.
caution: the amplifier should not be connected to ac power
until all connections are completed. High power 70volt
amplifiers present a serious shock hazard. Do not connect
speaker wires to the amplifier until all other connections are
completed.
4. Dig a 4” – 5” deep trench to run the speaker wires in.
5. Run the wire through the trench from your amplifier to the first
speaker location.
6. Connect the direct burial wire to each speaker wire, connections
should be made with either silicone filled wire connectors or
appropriate junction boxes. See Figure 4.
IMPortant: Be sure not to let any stray ‘+’ and ‘–’ strands
touch each other. touching strands can cause a short-circuit
that could damage your amplifier.
note: confirm that you have connected speaker “+” to
amplifier “+” and speaker “–” to amplifier “–”.
7. After all the speakers connections are completed, connect the
wires to your amplifier. See Figure 5 for reference.
8. Turn your amplifier on and test the system with your favorite
music. If the speakers are operating properly, refill the wire
trench and enjoy your new speakers.
