+12V Power
Connect the +12V terminal of the amplifier to the + terminal of the battery using the same diameter
as the ground cable, making sure you install in-line fuse holder, approximately 300 or 400 mm.
From the + terminal of battery, making sure that 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 20 inches or less).
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.

Using a dual amplifier conf iguration, 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.
When hooking two amplifiers to it, please check the power handling capabilities of your subwoofers
if they are not exceeded.

2~8 ohms
In linkable/bridgeable mode connection, total impedance must be more than 2 load.
Any impedance (load) smaller than 2 could damage the amplifier.

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.
