Installation

In case you install the amplifiers by yourself, please read the user manual very carefully, and follow the outlined instructions.

Mounting Preparation

Disconnect the negative (-) battery cable before mounting or making any connections.

Check the battery and alternator ground (-) connections. Make sure they are properly connected and free of corrosion. Before selecting a mounting location for the amplifiers, please take cooling and safety into consideration.

Avoid installing the amplifier on speaker boxes with excessive vibration !

The amplifiers have been designed with a good heat dissipation heatsink.

In order to avoid excessive heating, it is recommended that amplifier is installed in a well ventilated space

+12V(B+), GND, REM CONNECTION

+12V / B+ (POWER CONNECTION)

Before mounting the amplifiers, disconnect the negative (-) wire from the battery to protect any accidental damage to the amplifiers or the audio systems. The amplifiers are equipped with 0 AWG or 4 AWG power and ground terminals. Connect the power cables to power terminal labeled as + 12V.

As the amplifier is not equipped with fuses, external fuses are required.

Connect one end of the fuse holder to the power cable and the other end of the fuse holder to the positive battery terminal within 20 cm of the same cable.

This fuse location will protect the system and the vehicle against the possibility of a short circuit in the power cable.

Make sure that the fuses and the fuse holder are adequate for the desired application.

GND (GROUND CONNECTION)

Locate a secure grounding connection as close as possible to the amplifier.

Make sure the location is clean and provides a direct electrical connection to the chassis of the vehicle.

Connect one end of an equal sized cable as the positive cable to the location of ground.

It is important that the ground cable is as short as possible, but no longer than 75 cm at maximum.

Run one end of the cable to the grounding point.

Run the other end of the cable to the mounting location.

Connect the ground cable to the terminal labeled as GND.

REM (REMOTE CONNECTION)

Run a remote turn on cable from the switched + 12V source.

This may be a toggle switch, a relay, the source unit's remote ouput cable or power antenna trigger cable.

Connect the remote turn on cable to the power terminal labeled as REM.

For connection to the positive terminal of the battery (+12).

For optimum performance 0 gauge cable is recommended.

CAUTION

Before attempting to make any connections to power supply, input and output connectors, make sure the amplifier is in OFF state. Check polarity of cables carefully as using reversed polarity will cause damage to amplifier. And to prevent power loss and overheating of wiring, always use the recommended wire gauges.

CAUTION

Installation of the amplifier should be done in the following steps:

1. Ensure that the ground is appropriate, then connect it to the amplifier.

2. Next step is to connect the +12V wire. Ensure all power terminals are used.

This cable has to be fused at the battery for safety precautions.

3. The final step is connecting the switched remote.

CAUTION

Keep GROUND of equal length. This drawing is for illustration purpose only.

We recommend using 12 AWG speaker cables to obtain intended performance.

Run 12 AWG speaker cables from your speakers to the amplifier’s mounting location

Keep the speaker cables separate from the power cables and and the amplifier’s input cables.

Use grommets where the cables have to penetrate the vehicle chassis.

Connect the speaker wires according to the terminals on each speaker.

Strip 1cm, 3/8" of insulation of the end of each cable and twist the cables strands together tightly.

Make sure there are no stray strands that might touch other cables or terminals and cause short circuit.

Connect the cable ends to the amplifier as shown in the speaker wiring diagram.

Troubleshooting

Assure that the Power LED is on, if so please proceed with step # 3, if not, continue with the steps below;

1. Check the in line fuse (s) on the battery’s positive cable, and replace if needed.

2. Assure that the Ground is properly attached to the vehichle chassis on a clean metal point, tighten or

grind the connection point once again.

3. The amplifiers have high voltage protection. Make sure that the operating voltage is between 8.5V~

16V and voltages above this range will cause the amplifier to go into protect.

Protect LED is on

1. The Protect LEDS will light up under the possible circumstances;

a) The impedance connected is lower than specified rating.

b) Thermal PT can be activated if the impedance is lower than specified rating or if the supplied

voltage is insufficient.

c) Short circuitry, voltage and DC offset.

For short circuitry, check all cables including speaker wires, GND, battery’s positive cable.

For voltage, please check step # 3, for DC offset, make sure that voltage of no more than 4V is

available. Remove the RCA from the input and check if the amplifier is released from protection.

If so, check if the output from the Head unit has a DC of 4V and replace / repair if needed.

Audio output (no sound)

1. Assure that RCA connections from the Head unit and the amplifier are properly connected.

Check the entire cables for damages. Test the RCA inputs for DC volts with the source unit on, and

replace / repair if needed.

2. Check the routing of the cables, fuses and verify that all connections are connected properly.

3. Check if the speakers are functioning properly.

Turn on Thump

1. Disconnect the signal input to the amplifier, then turn it on and off.

a) If the noise is cancelled, then connect a delay turn on module on the REM wire running from

the source unit to the amplifier.

b) Use another 12V source for REM lead to the amplifier. If the noise is cancelled, use a relay

to isolate the amplifier from the turn on thump.

Poor bass response

1. Check that the polarity of the speaker cables are correct. Speakers connected in anti-phase will

cancel out each other, thus the bass response will be absent.

Engine noise

1. Ensure that all signal transferring wires (RCA, speaker cables etc) are kept well isolated from

power and ground wires.

2. Bypass all electrical components between the Head unit and the amplifier.

Connect the Head unit directly to the amplifier’s input. If the noise is eliminated, the unit bypassed

is the one creating the noise.

3. Remove the existing ground wires for all electrical components installed. Ensure that the ground point

is 100% metal which has been grinded and free of rust, paint, impurities etc.

4. Replace the ground cable of OEM battery / alternator and ensure it is grounded properly.

5. Test the battery and alternator load.

Ensure that the vehichle’s electrical system is in a good condition including distributor,

spark plugs / wires, voltage regulators etc.
