CAUTION: 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 unstable am-
plifier operation may result CAUTION This amplifier is not recommended for impedance loads below 2Q stereo and/or
4Q 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)
