+12V Power

Connect the +12V terminal of the amplifier to the + terminal of the battery using the same

diameteras the ground cable, making sure you install in-line fuse holder, approximately 300 or 400 mm.

From the + terminal of battery, make sure there is no fuse in the battery holder.

GROUND

Disconnect the battery and connect the GND (ground) terminal to the cars chassis.

Keep this cable as short as possible (not longer than 500 mm).

Making sure that the connection with the chassis is rust free and clear of paint or grime.

REMOTE

Connect the REM terminal of the amplifier to the power antenna terminal in the car ignition switch

using 12 or 16 ga. electrical wire.

First make the ground connection, then +12V wire connection and finally the remote

connection. Furthermore, the +12V wire must always be fused at the battery for protection

against possible damage. If you need to replace the power fuse, replace it with a fuse of

the same value. It may result in a serious hazard to use a fuse of a different type or rating.

This amplifier has a signal input terminal of RCA connector type for low level inputs.

Adjustment of input levels is accomplished by the gain control of both channels.

Adjusting this control allows the amplifier gain to be controlled to match and balance both

channels. The RCA input connector should be used when connecting the radio/cassette line out

and this connection is usually made using RCA-RCA connector wires.

DUAL AMP SPEAKER CONNECTION

Use 8 Gauge(AWG) wire cable

Caution

Using a dual amplifier configuration, the MASTER amplifier has total control over the SLAVE amplifier.

The positive terminal of the subwoofer's voice coil must be connected to the positive terminal of

the MASTER Amplifier and the negative terminal of the subwoofer's voice coil must be connected to

positive terminal of the SLAVE Amplifier. Since the dual amplifier configuration has tremendous

outputpotential, please ensure that your subwoofers can handle such a large amount of power.

When utilizing the dual amplifier configuration, it is important to note that the connected

speakers' load cannot be lower than 2Ω. Connecting a lower impedance load can

damage the amplifier and void your warranty.

This power amplifier has protection features to prevent damage from misuse or faulty conditions.

If the unit senses excessive heat, short circuited speakers or overload, protection LED will light up

and system will be turned off. Prior to checking the wiring for any fault, you should turn all level

controls down and turn off power. If the amplifier shuts down due to excessive heat, protection LED

will not light up. In this case, simply allow the amplifier to cool down.

Before removing your amplifier, refer to the list below and follow the troubleshooting instructions.

Always test the speakers and their wires first.

Trouble Shooting

PROTECTION LED LIGHTS UP WHEN AMPLIFIER IS POWERED ON

FUSE BLOW

OVERHEATING

Check the value of minimum speaker impedance.

Check speakers for short-circuits.

Check if there is good airflow around the amplifier.

Check if a good ground connection is present and check speakers for short-circuits.

Disconnect all RCA inputs from the amplifier. If hissing / engine noise disappears, replace the

RCA connectors and re-check. Then check the component driving the amplifier.

SOUND TOO LOW-DISTORTED SOUND

Check if the input level control has been set to match the output level of the unit.

Check the volume of head unit.

Check speakers for short-circuits.

Check if crossover frequencies have been properly set.

HIGH HISS-ENGINE NOISE IN SPEAKERS

Check the value of minimum speaker impedance.

Check for short-circuits on power cable and vehicle chassis.

AMPLIFIER DOES NOT POWER UP

Check if at least +12V DC is available on the battery power terminal.

Check if at least +13.8V DC is available on the remote terminal.

Check if a good ground connection is present. Check all fuses.

Check if protection LED is not lit.

Check if speaker wires are short-circuited.

Remove speaker wires and reset the amplifier. If protection LED still lights up,

then the amplifier is faulty.
