InstAllAtion

•For safety, disconnect the negative lead from the car battery prior to beginning the installation Trunk Mounting

Mounting the amplifier vertically on a surface will provide the best cooling for the amplifier.

Passenger Compartment Mounting

Mounting the amplifier in the passenger compartment will work as long as you provide a sufficient amount of air for the amplifier to cool itself. If you are going to mount the amplifier under the seat of the vehicle, you must have at least 1” (2.54cm) of air gap around the amplifier’s heatsink.

B+ Terminal

The B+ cable MUST be fused 18” (45cm) or less from the vehicle’s battery. Prepare the cable ends and install the fuse- holder under the hood. Connections should be water tight.

GND Terminal

Prepare a length of cable to be used for the ground connection. Prepare the chassis ground by scraping any paint from the metal surface and thoroughly clean the area of all dirt and grease. Fasten the cable to the chassis using a screw.

REM Terminal

Connect the REM wire to a switched 12 volt positive source. The switched signal is usually taken from the source unit’s auto antenna or the accessory lead. If the source unit does not have these outputs available, the recommended solution is to wire a mechanical switch in-line with a 12 volt source to activate the amplifier.

Input Connectors

Follow the diagram and connect the appropriate signal cables to the input terminals of the amplifier. Be sure that the sig- nal cables are routed close together and away from any high current wires.

Speaker Output Terminals

Connect the speaker system to the amplifier by inserting the wires into the corresponding output terminals and tighten the set screws. Follow the diagram for proper signal polarity. DO NOT chassis ground any of the speaker wires as unsta- ble amplifier operation may result. CAUTION: This amplifier is not recommended for impedance loads below 2W stereo and/or 4W bridged (mono).

Gain Control(s)

The amplifier is factory set for optimum dynamic range. The system levels may be adjusted by ear when using a source unit with higher or lower output levels by using the following procedure.

1.Turn the gain control to minimum (counterclockwise)

2.Play a music track with high dynamic content and turn up the source unit to at least 3/4 volume

3.Slowly increase the gain and set it just below audible distortion or until reaching a comfortable hearing threshold (which- ever occurs first)

TROUBLESHOOTING

Symptom	Diagnosis	Remedy
Amplifier does not turn on.	B+ or REM not between 10.5 and 15.5 volts	Check the alternator, battery, fuse, and wiring
	or no voltage present	and repair as necessary
	Amplifier is not properly grounded.	Check wiring and repair as necessary
Amplifier Noise	Voltage spike from source unit is entering	Connect turn-on module to REM terminal if
(Turn-On Pop)	amplifier’s input	pops are eliminated with no input signal to
		amplifier
Engine Noise	Noise is radiating into signal cables	Re-route signal cables away from sources of
		high current
