INSTALLATION AND MOUNTING

AMPLIFIER LOCA T/ON

The RUBICON amplifier employs highly efficient circuitry, a custom-engineered heat sink, and a unique Chassisink construction to maintain lower operating tem- peratures. Additional cooling may be required if the amplifier is located in a tightly confied 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 com- ponents. 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.

MOUNTING THE AMPLIFIER

a.Using the amplifier as a template, mark the holes on the mounting surface.

b.Remove the amplifier and drill the holes for the mounting screws.

C.Secure the amplifier to the mounting surface using the supplied hardware.

WIRING

a.Run and connect the audio signal and remote turn-on cables to the amplifier from the source unit.

b.Carefully Nn the positive cable from the amplifier to a fuse or circuit breaker

within 18” of the battery.

C.Connect the fuse or circuit breaker lead 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.

POWER UP

Power up the system and look at the Power LED; there may be a 2-3 second delay from the time the source unit is turned on to the time that the LED on the amp turns on, which is normal. Once the amplifer LED is on and the source unit is playing, you should have sound coming from the speakers.

LEVEL SETTING

The input levels are adjusted by means of the input level controls located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better S/N Ratio even when using sources with minimal output.

In the ideal situation, all components in the audio system reach maximum undistorted output at the same time. If you send a distorted signal to an amplifier, it is simply going to amplify distorted information. The same holds true if an outboard proces- sor or crossover begins to distort before you have maximum output from the ampli- fier. By setting all components to reach clipping at the same time, you can maxi- mize the output of your system. For the RUBICON amplifier, follow these steps for setting the input levels:

1.Turn the amplifier’s input levels to minimum position (counter-clockwise)

2.Set the source unit volume to approximately 3/4 of full volume.

3.While playing dynamic source material, slowly increase the amplifiers’ input level until a near maximum undistorted level is heard in the system.

Once the amplifier is installed and the proper levels set, place the front spoiler in position, and secure it using the supplied hardware.
