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 MARINE 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.
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-MARINE series amplifiers have the protection features to prevent any damages
from misuse or faulty conditions.
If RP-MARINE 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-MARINE 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-800.1DM AND RP-1500.1DM.
RP-75.4ABM and RP-150.4ABM ARE 2ohm stereo or 4ohm mono.
@ 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-800.1DM AND RP-1500.1DM’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.
