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.
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.
1. Locate the subwoofer in an area that will not flood with standing
water.
2. Dig the hole using the guide. See figure 2
LS10SUB: A=4” B=26” C=16” D=13”-16”
Note: (for variable depth see Figure 3 below)
3. Prepare a ‘bed’ for the subwoofer that is reasonably free of
voids and large rocks.
4. Install and secure the rubber elbow onto the canopy and ABS
tube subassembly using one of the supplied hose clamps.
5. Install the rubber elbow and canopy assembly on the subwoofer
enclosure; do not tighten the second hose clamp at this point.
When placing the rubber elbow onto the subwoofer, it is
recommended to add General Purpose Marine Grease to the
inside of the elbow. This grease is available under the brand
name Sta-Lube. This lube will act like a water barrier and ensure
that water won’t enter in through the elbow connection.
6. Place the subwoofer into the ground.
7. Rotate the cabinet as required so that the bottom of the canopy
will be 4” above the finished grade after backfill.
8. Once the subwoofer is in the correct location tighten the hose clamp
at the connection between the enclosure and the rubber elbow.

9. Dig a 4” – 5” deep trench to run the speaker wires in.
10. Run the wire through the trench from your amplifier to the first
speaker location.
11. 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
“–”.
12. After all the speakers connections are completed, connect the
wires to your amplifier. See Figure 5 for reference.
13. 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.
