INSTALLATION AND MOUNTING
1. AMPLIFIER LOCATION
The REFERENCE Class A PICASSO amplifier employs 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
/Bridged Mono/Mixed Mono switches to the appropriate positions (see pages 14 -
17).
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!
f. Re-connect the fuse or circuit breaker.
5. POWER UP
Power up the system and look at the red "POWER" LED. There may be a 2 -3 second delay from the time the
the source unit is turned on to the time that the LED on the amp turns on, which is normal. Once the amplifier
power LED is on and the source unit is playing, you should have sound coming from the speakers.
NOTE: There may be a small spark when connecting the power and ground lead to the amplifier for the first time.
This is caused by current rushing into the amplifier to charge the power supply capacitors, and is completely
