Installation Warnings and Tips
•Disconnect the negative (–) lead from your vehicle’s
battery.
•At the installation sites, locate and make a note of
all fuel lines, hydraulic brake lines, vacuum lines
and electrical wiring. Use extreme caution when
cutting or drilling in and around these areas.
•Choose a safe mounting location away from moisture.
•Make sure there is sufficient air circulation at the
mounting location for the amplifier to cool itself.
•Mount the amplifier, using the supplied hardware.

•60W RMS x 2 channels @ 2 ohms, 14.4V supply and
≤1% THD + N*
•120W RMS x 1 channel @ 4 ohms, 14.4V supply and
≤1% THD + N*
•THD + N: 0.05% (rated power @ 4 ohms)*
•Signal-to-noise ratio: 85dBA
(reference 1W into 4 ohms)*
•Signal-to-noise ratio: 101dBA
(reference rated power into 4 ohms)
•Frequency response: 10Hz – 100kHz (–3dB)*
• Total peak power: 240 watts
*CEA-2006A-compliant
0Speaker Output Connectors
•Connect the speakers to these terminals,
observing proper polarity.
•Two-channel operation: Connect the left
speaker to the L+ and L– terminals and the
right speaker to the R+ and R– terminals.
•One-channel (bridged) operation: Connect the
single speaker to the R+ and L– terminals.
•Minimum speaker impedance for 2-channel
operation is 2 ohms. Minimum speaker impedance
for 1-channel (bridged) operation is 4 ohms.
1Fuse
•Replace only with the same type and rating.
2Power Input Connectors
•+12V: Connect to the positive terminal of the
vehicle’s battery. 10 AWG wire is recommended.
Install an appropriate fuse holder and fuse (15A
minimum) within 18 inches of the battery. Make
sure the wire is not damaged or pinched during
installation. Install protective grommets when
routing wires through the firewall or other sheet
metal.
•GND: Connect to the vehicle’s chassis. Refer to
the picture below.
•REM: Connect to the “Remote Out” lead from
the source unit or to a source of switched
12V+ (ACC).
3Input Connectors (RCA)
•Connect to the RCA outputs from the source unit
or signal processor.
4Input-Level Control
•Used to match the input level of the amplifier
to the output level of the source unit.
•See Afor the adjustment procedure.
5Power On LED
•Illuminated when the amplifier is on.
6Protect LED
•Illuminated under any of the following fault
conditions: battery over/under voltage, short
circuit in speaker wires, amplifier is too hot,
amplifier’s output circuit has failed (DC voltage
is present in the amplifier’s output).
7Crossover-Frequency Control
•12dB/octave crossover, variable from
32Hz to 320Hz.
•See Bfor the adjustment procedure.
8Crossover-Filter Selector
•LP: Select for subwoofer(s).
•FLAT: Select for full-range speakers when
no subwoofer will be used in the system.
•HP: Select for midrange speakers or
full-range speakers when a subwoofer is
used in the system.
9Bass-Boost Control
•Provides 6dB of boost at 50Hz. Set the Bass-
Boost control according to your preference,
being careful not to apply enough boost to
damage the speaker(s).
ASetting Input Level
ATurn Input-Level control counterclockwise to
6V (minimum).
BWith a dynamic music track playing, turn the
head unit’s volume control to the 3/4 position.
CTurn Input-Level control clockwise until the
music is so loud that it no longer sounds clear
(distortion is present in the output).
DTurn Input-Level control counterclockwise
gradually, just until the music sounds clear,
once again.
EInput level is now adjusted correctly.
BSetting the Crossover
ACrossover setting for 5" or larger full-range
speakers when no subwoofer is included in
the system.
BCrossover setting for midrange and/or
full-range speakers when a subwoofer
is included in the system.
CCrossover setting for subwoofers.
Note: Acceptable frequency ranges are indicated
in gray.

Amplifier Troubleshooting Guide
1. Status LED on Amplifier not Lit - Head Unit (Source) Turned ON
Verify: A. Remote turn-on wire from source to amplifier has proper voltage
B. Power (B+) connections at amplifier, terminal blocks, and battery are secure
C. Ground (GND) connections at amplifier and vehicle chassis are secure
D. Battery B+ fuse (if used) is OK
E. Amplifier fuse is OK
F. B+ at battery and B+ at amplifier has proper voltage
2. Status LED’s Lit, No Output from Speakers in Normal Operating Condition
Verify: A. RCA cables from amplifier to source are securely connected
B. Volume adjustment on amplifier is correctly adjusted
C. Source is ON and playing
3. Engine Noise From Speaker(s)
Turn source OFF, Disconnect RCA cables at amplifier. If noise stops, check equipment & cables leading
to amplifier.
Verify: A. RCA cables are of good quality with no breakage to internal shields
B. RCA cables from source to amplifier are not run alongside any power cables
4. Amplifier Output Distorted Music
Verify: A. Source output music to amplifier is not distorted
B. Source output sensitivity is correctly adjusted
5. Amplifier Shuts Down, Green LED’s are Lit - Amplifier is in Thermal Protection Mode
Verify: A. Amplifier is mounted with adequate air circulation around heatsinks or vents
B. Amplifier is not mounted under carpet or sealed enclosure
C. Speakers meet correct impedance for application (mono or stereo hookup)
6. Amplifier Does Not Turn ON, and Red LED is Lit Amplifier (and not Connected to a Shorted Speaker)
Verify: A. Speaker crossover (if used) is not defective
