POWER AND GROUND

To ensure maximum output from your RUBICON amplifier, use high quality, low- loss power and ground cables and connections. The RUBICON amplifiers will accept up to 4 or 8 gauge power and ground cables. Determine from the chart below the minimum and maximum gauge power and ground wire for your applica- tion_

	up to 10’			up to 20’

CIRCUIT BREAKERS AND FUSES

EXTERNAL

Like all audio components, the RUBICON amplifier must be fused near the battery. A fuse or circuit breaker must be located within 18” of the batterv. This will prevent a fire in the event of a shorted cable. See the chart below to determine the correct fuse value.

INTERNAL

The RUBICON255, 355 81 555 amplifier are fused with automotive-type fuses. In the event of blown power supply fuses, replace with the correct value fuse found in the chart below. Never replace the fuse with a higher value than what is sup-

plied. This may result in amplifier damage and will void the warranty!

RUBICON255,355 & 555 Amplifier Fuse Values

		Amplifier Fuse			Battery Fuse / Circuit Breaker

IRuaconr255	1 30 amp		automotive	1	40 amp

RUB/CO/V355		(2) 20 amp automotive			50 amp

RUBICON555		(2) 30 amp automotive			80 amp

REMOTE TURN-ON

Connect the “Remote” line to the turn-on lead from the source unit. When+12 Volts is received, the amplifier will turn on.

SIGNAL CABLE

Use a high quality cable that will be easy to install and has minimal signal loss to guarantee optimum performance.

SPEAKER CABLE

The RUBICON amplifiers will accept up to 8 gauge speaker cable. Use a high quality, flexible, multi-strand cable for best performance and longevity.

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 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 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.Reconnect 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.
