BATT ( 12V POWER )
Before mounting amplifiers, disconnect the negative cable from the battery to protect
any accidental damage to your awesome amplifiers and audio system.
All amplifiers are designed to use 4 gauge power and ground connection.
Connect the power cables to power terminal 12V.
All RP-series amplifiers are not equipped with fuses so that external fuses should be used.
Connect one end of fuse holder to the power cable going into the amplifiers and the other
end of fuse holder to positive battery. This fuse location will protect the system and
the vehicle against the possibility of a short circuit in the power cable.
Be sure to use fuses and fuse holder adequate for the application.
GND ( GROUND )
Locate a secure grounding connection as close to amplifier as possible.
Make sure the location is clean and provides a direct electrical connection to the frame of
the vehicle. The ground needs to have as low of a resistance as possible.
Connect one end of a short piece of the same size cable as the power cable to
the grounding point or to one of your batteries or battery bank. Run the other end of 4 ga
cable to the mounting location of the amplifiers for connection to the amplifiers’ ground
terminals and connect the ground cable to the GND ( ground terminal ).
REM ( REMOTE )
Run a remote turn on cable from the switched 12V source . This may be a toggle switch,
a relay, your source unit's remote trigger cables, or power antenna trigger cable.
Connect the remote turn on cable to the REM ( remote ) terminal.

RP-series amplifiers have the protection features to prevent any damages from misuse or
faulty conditions.
If RP-series amplifiers sense excessive heat, short circuited speakers DC, or voltage
the protection indicator will light, and the system will be turned off.
In order to check the problem, you should turn all levels down and all power off and carefully
check the installation for wiring mistakes or short.
If RP-series amplifiers shuts down due to excessive heat, They will be working later
when it is cooled down
Before removing your amplifier, refer to the list below and follow the suggested procedures.
TROUBLE SHOOTINGS
NO SOUND ( NO OUTPUT )
@ Please check all connections, cables, routing of cables, short & voltage.
@ Please check the fuses , If they are blown, please replace with new one.
@ Please check whether speakers work well, you can test speakers by connecting to
another amplifier
PROTECTION
@ Please check overload, overheat ( thermal ), short and voltage, DC offset.
@ Minimum working impedance is 1 ohm for RP-350.1D, RP-800.1D, RP-1500.1D and RP-2000.1D.
RP-75.4AB and RP-150.4AB is 2ohm stereo or 4ohm mono.
RP-600.5 is 2ohm stereo or 4ohm mono for CH1 ~ CH4 and 1ohm for CH5.
@ If amplifiers are shut down due to heat, they will be on some minutes later after cooling down.
Please make better airflow and no obstruction around amplifiers for thermal protection.
@ RP-350.1D, RP-800.1D, RP-1500.1D, RP-2000.1D, RP-75.4AB, RP-150.4AB & RP-600.5’s working voltage
is 8.5 ~ 16Volts.
@ When over 4V DC comes into amplifiers, then, they will be DC protected. Check whether amplifiers
work after removing RCA-Input.
If amplifiers work, then check DC by checking RCA-input .
When DC is over 4V at input, try by replacing +12V source unit .
DISTORTION & NOISE
@ Readjust input level and check the speaker quality at another amplifier.
Replace poor quality speakers with good quality ones.
@ Check amplifiers and head unit’s ground contact. all grounds should be common.
@ Check RCA Jack, then replace with new one or reroute RCA Jack.
@ Engine noise is caused by poor grounding of amplifiers, head unit, other components, battery or
alternator, so please check all grounding connection.
POOR BASS RESPONSE
@ Please check speaker cables and reverse polarity.
