INSTALLATION AND MOUNTING
1. AMPLIFIER LOCATION
The REFERENCE Class A amplifiers employ highly efficient circuitry and a
unique Chassisink
TM design to maintain lower operating temperatures.
Additional cooling may be required if the amplifier is located in a tightly
confined area or when driving especially low impedance loads at extremely
high levels.
When mounting the amplifier, it should be securely mounted to either a panel
in the vehicle or an amp board or rack that is securely mounted to the vehicle.
The mounting location should be either in the passenger compartment or in the
trunk of the vehicle, away from moisture, stray or moving objects, and major
electrical components. To provide adequate ventilation, mount the amplifier so
that there are at least two inches of freely circulating air above and to the sides
of it.
2. SWITCHES
Set the Coherent Stereo TM /Mixed-Mono/Bridged Mono and Amplifier crossover
switches on the bottom of the amplifier to the appropriate positions before
bolting down the amplifier (see pages 13 - 16). Be sure to replace the hole
plugs.
3. MOUNTING THE AMPLIFIER
a. Using the amplifier as a template, mark the mounting surface.
b. Remove the amplifier and drill the holes.
c. Mount the amplifier to the surface using the provided hardware.
4. WIRING
a. Run and connect the audio signal and remote turn-on cables to the
amplifier from the source unit.
b. Carefully run the positive cable from the amplifier to a fuse or circuit
breaker within 18” of the battery.
c. Connect the fuse or circuit breaker to the battery. Leave the circuit breaker
off or the fuse out until everything is bolted down.
d. Secure the ground cable to a solid chassis ground on the vehicle. It may
be necessary to sand paint down to raw metal for a good connection.
e. Double check each and every connection!
NOTE: There may be a sizable spark when connecting the power and ground
lead to the amplifier for the first time. Please see the comment on the previous

Key to Callouts
1. Fault LED - Indicates a blown fuse.
2. Power LED - Indicates amplifier power on.
3. Input Overload Indicators - Indicates the signal input level or input gain
level is too high.
4. Input Level Selector Switch - Selectable input sensitivity range from 0.2-
2 Volts RMS, or from 0.5-5 Volts RMS.
5. Left Channel Balanced / Unbalanced Input Selector Switch - Select
"Balanced" to use the 6 pin Balanced signal Input. Select "Unbalanced" to
use the RCA signal inputs.
6. Right Channel Balanced / Unbalanced Input Selector Switch - Select
"Balanced" to use the 6 pin Balanced signal Input. Select "Unbalanced" to
use the RCA signal inputs.
7. Main Fuse - Main power supply fuse. Replace only with the same value
fuse.
8. +12V - Connected to a fuse or circuit breaker, then to the battery's positive
post.
9. GND - Main ground connection. Bolt to a clean chassis ground in the
vehicle.
10. REM - Remote turn-on input from the head unit. Accepts +12V.
11. Speaker Output Connections - Left and right channels.
12. Input Level - Independent Left and Right channel input level controls.
13. Balanced Signal Input Connector - 6-pin Balanced signal input
connector for use with the Soundstream BLT Balanced Line Transmitter.
14. Inputs - Right and left channel RCA (Unbalanced ) inputs; only right
channel input is used in "Mono" mode.
15. Coherent Stereo/Bridge/Mixed Mono switch - Select "Bridge" for
bridged mono operation (use right channel input). Select "Stereo" for
coherent stereo operation. Select "Mixed Mono" for simultaneous stereo /
bridged mono operation.
