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 to
protect the amplifier from possible damage. If you need to replace the power fuse,
replace it with a fuse of the same value. It may cause serious damage to your amplifier
and/or your vehicle if you use fuses with different type or rating.
+12V Power
Connect B+ terminal of the amplifier to the + terminal of the battery using the wire that
has the same diameter of the ground cable.
Make sure you install in-line fuse holder approximately 300 to 400 mm away from
the + terminal of the battery. Please ensure
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 (no 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.

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.

FUSE BLOWING
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.
