INSTALLATION STEP 4
INSTALLATION AND MOUNTING
1. AMPLIFIER LOCATION
The REFERENCE Class A amplifiers employ highly efficient circuitry and a unique ChassisinkTM 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.

Set the Coherent
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
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.
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
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!
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
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
11.Speaker Output Connections - Left and right channels.
12.Input Level - Independent Left and Right channel input level controls.
13.Balanced Signal Input Connector -
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.
