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 utilizes RCA type low-level input terminals. Input level is set by adjusting the "sensitivity" knob, which controls both channels. As illustrated above the "Input" RCA pair is connected to the output of the radio via RCA to RCA cables.

Wired Remote Controller

REMOTEConnect the REM terminal to either the remote output lead from the radio or another switched 12V supply such as the power antenna wire.

+12V PowerConnect the +12V terminal of the amplifier to the + terminal of the battery using a large gauge power wire (preferably 4 gauge). It is critical to utilize an in-line fuse within 8 inches of the battery to ensure safe operation of the amplifier. Make sure that the fuse is not installed while you are connecting the + wire to the battery terminal to avoid sparking and possible injury or damage.

GROUNDDisconnect the battery and connect the GND (ground) terminal to the cars chassis. Keep this cable as short as possible (not longer than 10 inches). Be certain that the chassis ground point is free of rust, paint, and grime to ensure a solid electrical connection.

Using a dual amplifier configuration, the MASTER amplifier has total control over the SLAVE amplifier. When using dual amplifier to operate subwoofer, 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. Be advised that the dual amplifier configuration has tremendous output potential,so 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 speaker load can be no lower than 2 ohms. Connecting a lower impedance load can damage the amplifier and void your warranty

Caution

This power amplifier has protection features to prevent any damages from misuse or faulty conditions. If the unit senses excessive heat, short circuited speakers or overload, the protection indicators will light, and the system will be turned off. In order to check the occurred problem, you should turn all levels down and all power off and carefully check the installation for wiring mistakes or short. If the amplifier shuts down due to excessive heat, the protection indicators will not light : simply allow time for the unit to cool.Before removing your amplifier, refer to the list below and follow the suggested procedures. Always test the speakers and their wires first.

PROTECTION LED ILLUMINATES WHEN AMPLIFIER IS POWERED UP

FUSE BLOWING

OVERHEATING

Check that the minimum speaker impedance is correct.

Check speaker shorts.

Check that there is a good airflow around the amplifier.

Check a good ground and for speaker shorts.

Disconnect all RCA inputs from the amplifier. If hiss/noise disappears, check

it with a good RCA interconnect. Then check the component driving the

amplifier.

SOUND TOO LOW-DISTORTED SOUND

Check that the input level control is set to match the output level of the unit.

Check the head unit volume.

Check speaker shorts.

Check that crossover frequencies have been properly set.

HIGH HISS-ENGINE NOISE IN SPEAKERS

Check that the minimum speaker impedance is correct.

Check short on power cable and vehicle chassis.

AMPLIFIER IS NOT POWERED UP

Check that there is battery power on the +12V terminal.

Check that remote terminal has at least 13.8V DC remote connection.

Check a good ground connection. Check all fuses.

Check the protection LED is not lit.

Check shorts on speaker wires.

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

comes on, then the amplifier is faulty.
