Power Connection
+12V Power
Connect the +12V terminal of the amplifier to the + terminal of the battery
using a large gauge power wire (preferably 1/0 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.
GROUND
Disconnect 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.
REMOTE
Connect the REM terminal to either the remote output lead from the radio
or another switched 12V supply such as the power antenna 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.

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

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.
