INSTALLATION
Any deviation from the connection specifications recommended may cause serious damage to
the amplifier, speakers and/or vehicle electrical system. Please double-check the connections
before turning the system on.
PROCEDURE
1. Disconnect the vehicle’s negative battery connection.
2. Using the supplied allen wrenches, remove the four (4) screws from the annealed stainless steel
amplifier cover. Put this aside until your installation is complete to prevent damage to the cover.
3. Place your Xtant amplifier at the predetermined mounting location. Using a felt pen, mark
the exact position of the mounting holes on the mounting surface. Set your Xtant amplifier
aside. Use a sharp, precise blade to cut small circles in the carpet and padding around the
four marks denoting your mounting holes to expose the metal underneath. Use a center
punch to make an indentation in the metal to ensure that you drill the exact position for the
screws. Drill the four holes as marked.
4. Temporarily mount your Xtant amplifier using the four (4) long screws provided.
5. Run a power cable from the vehicle’s battery through the firewall and through the interior
of the vehicle connecting one end to your Xtant amplifier’s B+ terminal and connecting the
other end to the positive post on the battery.
NOTE: Install a circuit breaker/fuse within 18" of the battery. This effectively lowers the risk of
severe damage to your vehicle should a short circuit ever occur in the audio system. Do not install
the fuse in the fuse holder until all installation steps have been completed.
6. Find a good ground spot on the vehicle’s chassis and remove the paint to reveal bare metal at
the contact point. Attach the ground wire to that contact point and connect the other end of
the ground wire to the GND terminal of your Xtant amplifier.
7. Connect a Remote Turn-on wire from your source unit to your Xtant amplifier’s REM terminal
(14 or 16 gauge wire). If your source unit does not have a dedicated Remote Turn-on lead,
you may connect to the source unit’s Power Antenna lead.
8. Connect RCA cables from your source unit to your Xtant amplifier’s RCA input jacks. If RCA
(low) level output is not available, use Xtant’s High Level Adapters (HLA—not included) to
connect the speaker level (high level) wires to a set of RCA cables.
9. Connect your speakers to your Xtant amplifier’s speaker terminals using 12 gauge minimum
speaker cable.
10. Double-check all the previous installation steps, in particular, the wiring and component
connections. Securely mount the amplifier. Remove the protective film and screw the
annealed stainless steel cover back onto the amplifier.
11. If everything is in order, reconnect the vehicle’s negative battery connection and begin
adjusting your amplifier. NOTE: Be sure that the Gain Level on the amplifier is turned all the
way down (counter clockwise) before proceeding with adjustments.
