RCA (LOW LEVEL) INPUT CONNECTION
Both amplifiers have RCA input connectors that can be used for low level inputs and hi level
inputs (Using the RCA Fly Lead/s included):
For low level input (RCA output from Head Unit)
Connect the left & right RCA output from the Head Unit to the left and right RCA inputs of the amplifier.
Adjust the Input level (Gain) on the amplifier to the same output level of the Head Unit for distortion
free sound e.g. if the Head Unit has 5volt output, adjust the amplifiers "Gain" to match the 5volt signal.
This is done by using an Oscilloscope.

SPEAKER (HIGH LEVEL) INPUT CONNECTION
For hi-level input (speaker wire output from Head Unit):
•Connect only the + Positive speaker wire from the Head Unit's left channel to the "+" left RCA Fly Lead
•Connect only the + Positive speaker wire from the Head Unit's right channel to the "+" right RCA Fly Lead
•Solder the positive speaker wire to the positive (conductor) of the RCA Fly Lead and then insulate, using
heat shrink for best results. Be sure to insulate (or tape back) "-" negative wires that are not being used.
Adjust the Input level (Gain) on the amplifier to the same output level of the Head Unit for distortion free sound
e.g. if the Head Unit has 5volt output, adjust the amplifiers "Gain" to match the 5volt signal. This is done by
using an Oscilloscope.

POWER CONNECTION
+12V Power
Connect the +12V terminal of the amplifier to the + terminal of the battery. Use the same diameter
cable for ground. Ensure an in-line fuse holder is installed approximately 300 or 400 mm from the
positive battery terminal.
GROUND
Connect the GND (ground) cable to the vehicle chassis.
Keep this cable as short as possible (less than 500 mm).
Ensure that the connection to the chassis is rust free and clear of paint or corrosion.
REMOTE
Connect the REM terminal of the amplifier to the amplifier trigger wire of the head unit using 12 or 16
ga cable.
First connect the ground cable securely to vehicle's chassis. Then connect +12V
circuit and finally the remote connection. The +12V cable must always be fused
near the battery for protection against possible damage. When replacing a power
fuse, always replace it with a fuse of the same value.

TROUBLE SHOOTING

OVERHEATING
Check the 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 source unit driving
the amplifier.
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.
HISS-ENGINE NOISE
Check the value of minimum speaker impedance.
Check for short-circuits on power cable and vehicle chassis.
This power amplifier has in-built protection features to prevent damage. If the unit senses excessive
heat, short circuit or overload, the protection LED will light up and the system will shutdown. Prior to
checking the wiring for faults, turn all level controls down and turn power off. If the amplifier shuts
down due to excessive heat, the protection LED will not light up. In this case, simply allow the
amplifier to cool down. Before removing your amplifier, refer to the troubleshooting guidelines below.
Always test the speakers and their wires first.
AMPLIFIER DOES NOT POWER UP
Check if at least +12V DC exists at the battery power terminal.
Check if at least +13.8V DC is present on the remote terminal.
Check if a good ground connection is present. Check all fuses.
Check if protection LED is lit.
Check if remote wire is connected to remote turn-on wire of head unit.
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.
