Important Safety Information
See the Important Safety and Product Information guide in the product box for product warnings and other
important information.
This device must be installed according to these instructions. Failure to install this device in accordance with
these instructions could result in serious personal injury, damage to the device and/or vehicle, or poor product
performance.
To avoid possible serious personal injury or damage to the device and vehicle, disconnect the power supply to
the vehicle's audio system before beginning to install the device.
Continuous exposure to sound pressure levels over 100 dBA may cause permanent hearing loss. The volume
is typically too loud if you cannot hear people speaking around you. Limit the amount of time you listen at high
volume. If you experience ringing in your ears or muffled speech, stop listening and have your hearing checked.
To avoid possible personal injury, always wear safety goggles, ear protection, and a dust mask when drilling,
cutting, or sanding.
When drilling or cutting, always check what is on the opposite side of the surface to avoid damaging the vehicle.
It is strongly recommended that you have your audio system installed by a professional installer to ensure
optimum performance.
You must read all installation instructions before beginning the installation. If you experience difficulty during
the installation, go to

Page 5: Connecting To Power
Connecting to Power NOTICE You must not connect the power wire to the amplifier and battery or circuit breaker before you complete all of the other connections. Connecting the amplifier to power before you complete all of the other connections may cause damage to your audio system. - Page 6 Power Cable Gauge Guide You should use 4 AWG (21.1 mm ) wire for most installations. If your total amperage is higher than 65 A, and your cable run is longer than 10 to 13 ft. (3 to 4 m), you can use these tables to determine if you need to use a larger gauge of wire.

Page 7: Signal And Speaker Connection Considerations
Signal and Speaker Connection Considerations When connecting your stereo and speakers to the amplifier, observe these considerations. • You can send signals to the amplifier through the use of two, four, or six RCA inputs (Amplifier Configuration Controls, page 11). • You can connect either line outputs or speaker outputs from the stereo to the RCA inputs on the amplifier. •... - Page 8 Connecting Multiple Speakers or Subwoofers in Parallel You can connect multiple speakers or subwoofers with the same impedance rating, model number, and type together in parallel. When connecting speakers of the same impedance rating in parallel, you must calculate the total impedance by dividing the common impedance rating by the total number of speakers connected in parallel.
- Page 9 Connecting a Speaker or Subwoofer in Bridged Mode Connecting a speaker or subwoofer in bridged mode increases the amount of power that can be delivered by combining two output channels together. This is beneficial for large subwoofers that move large volumes of air and for playing speakers louder without experiencing clipping in the audio.

Page 10: Completing The Connections
Completing the Connections Before you connect the amplifier to the power source, you must complete all other connections to the amplifier. 1 Verify all speaker wires are connected to the speakers and the amplifier. 2 Verify all RCA cables are connected to the amplifier and the stereo. 3 Verify the ground cable is connected to the amplifier and the battery (Connecting to Power, page 5). -
