Consult with your electrical contractor about proper grounding.
Unpacking system components
There are several factors to consider before installing Earthquake
Sound’s .ROCK-on series
• What are the intended listening zones?
• What system options and accessories might be required for
features such as local sources, etc.?
• From where in each zone will the listener prefer to control the
system? Where will the remote gains be located? Where will the
speakers be located?
• Where will the source equipment be located?
System installation considerations
Connection tips
• Keep the original carton and packing materials for future
shipment or storage.
• Check for any visual signs of damage. If you encounter any
concealed damage, consult your Earthquake Sound dealer
before proceeding with unit installation.
• Retain the sales receipt as it established the duration of the
limited warranty and provided information for insurance
purposes.

1. Use direct burial wire and measure out how much you will need.
2. Dig a 6-inch deep trench to each speaker.
3. Connect the speaker wire to the speaker. It is recommended that you use heat-shrink tubing
to seal each individual conductor, then heat-shrink the two connections together.
Make sure that all connections are secure. Apoor connection can lead to corrosion and a
damaged speaker.
4. Run the wire through the trench to the amplifier.
5. Connect the speaker wire to the terminals on the back of your amplifier.
Make sure that the speaker wires’ polarity is connected correctly.

Earthquake Sound’s XJ-300FR Stereo amplifier can be used for your ROCK-on 2.1 system.
In tri-mode wiring, the user can connect the 2 channel stereo and the mono at the same time.
The subwoofer connection below demonstrates a series wiring formula which has a load

To simplify the wiring process, use Earthquake Sound’s SWAT 2.4 Wireless Transceiver
1. Connect the rock speakers and subwoofer to the XJ-300FR amplifier as shown above.
2. Connect the SWAT 2.4 Receiver to the XJ-300FR amplifier through the RCAinputs.
3. Connect the SWAT 2.4 Transmitter to any music player that has a mini jack or RCA output.
Note: Make sure both the Transmitter and the Receiver are connected to a power source,
