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.

Specifications

• 75W RMS x 2 channels @ 4 ohms and 1% THD + N*≤

• 110W RMS x 2 channels @ 2 ohms and THD + N*≤1%

• THD + N: 0.07% (rated power @ 4 ohms)

• Signal-to-noise ratio: 90dBA

(reference 1W into 4 ohms)*

• Signal-to-noise ratio: 108dBA

(reference rated power into 4 ohms)

• Frequency response: 10Hz – 100kHz (–3dB)

• Max power: 220 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.

1Fuses

• 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 (30A

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).

3Aux Output Connectors (RCA)

• Nonfiltered pass-through output. Connect

to the input of an additional amplifier.

4Input Connectors (RCA)

• Connect to the RCA outputs from the source unit

or signal processor.

5Input-Level Control

• Used to match the input level of the amplifier

to the output level of the source unit.

• See Bfor the adjustment procedure.

6Front Crossover-Frequency Control

• 12dB/octave crossover, variable from

32Hz to 320Hz.

• See Cfor the adjustment procedure.

7Crossover-Filter Selector

• LPF: Select for subwoofer(s).

• FLAT: Select for full-range speakers when

no subwoofer will be used in the system.

• HPF: Select for midrange speakers or

full-range speakers when a subwoofer is

used in the system.

8Bass-Boost Control

• Set the Bass-Boost control according to your

preference, being careful not to apply

enough boost to damage your speaker(s).

9Power On LED

• Illuminated when the amplifier is on.

AProtect 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).

BSetting 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.

CSetting 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.
