INTERNAL

The REFERENCE amplifiers are fused with automotive-type fuses. In the event of blown powersupplyfuses, the “FaulY’indicator on the top panel will light. The fuses are accessible via a plastic plug on the bottom of the amplifier. See the chart below to determine the fuse value. Never replace the fuses with a higher value than what is supplied. This may result in amplifier damage

and will void fbe warranfy~

Amplifier Fuse Values

Amplifier	Amplifier Fuse	Battery Fuse /
		Circuit Breaker
REFERENCE414s	(2) 25 amp automotive	60 amp
REFERENCE&l&	(2) 30 amp automotive	80 amp

REMOTE TURN-ON

Connect the “Remote” to the turn-on lead from the source unit. When+I2 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. Soundstream’s DL.1 and SL,l are ideal when using the Unbalanced RCA inputs. (While using the Balanced DIN input on the Reference644s, use the cable supplied with the BLTTY or BLT4TY).

SPEAKER CABLE

The REFERENCE amps will accept up to 8 gauge speaker cable. Use a high quality, flexible, multi-strand cable for best performance and longevity. Soundstream Speaker120 & 160 (12 and 16 gauge) are ideal.

INSTALLATION AND MOUNTING

1.AMPLIFIER LOCA T/ON

The REFERENCE amplifiers employ highly efficient circuitry and a unique Chassisink’” design to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly donfined 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 StereoTM/Mixed-Mono/Bridged Mono and crossover switches on the bottom of the amplifier to the appropriate positions before bolting down the amplifier (see pages 20 - 25). Be sure to replace the hole plugs.

“.

7 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!

g.Re-connect the fuse or circuit breaker.

about connecting power and gmond wires to your amplifier.

5. POWER UP

Power up the system and look at the red High 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.
