BATT    (   12V POWER )

Before mounting amplifiers, disconnect the negative cable from  the battery to protect 
any accidental damage to your amplifiers and audio system. 
RP-2000.1D, RP-3500.1D & RP-4500.1D are designed to use o ga power and ground connection
Rest of RP 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.

STRAPPABLE CONNECTION

Strappable connection makes two of same amplifiers strapped to 2 ohm. 
Strappable connection makes the power double than their 1 ohm power.
Please read the following connection and diagram carefully to make correct connection.

INPUT CONNECTION ;
Step 1. Connect the Master amplifier to the head-unit and set its output master / input slave switch to 
output master. 
Step 2. Set Slave amplifier output master / input slave switch to slave input.
Step 3. Connect RCA cable from the master to slave amplifier as shown in the diagram.

POWER & SPEAKER CONNECTION ;
Step 1. Connect speaker cable (   ) on master amplifier to subwoofer (   )
Step 2. Connect speaker cable (   ) on slave amplifier to subwoofer (   )
Step 3. Connect speaker cable (   ) on master amplifier to speaker cable (   ) on slave  amplifier

+12V SOURCE

Fully adjusted signal is transferred from master to slave amp via Rca cable.
Master amplifier controls all crossover and remote control over Slave amplifier

RP-series amplifiers have 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, short & volta ge.

  @ 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, RP-2000.1D, RP-3500.1D 
     and RP-4500.1D. RP-75.4AB and RP-150.4AB is 2 ohm stereo or 4 ohm mono.
     RP-600.5 is 2 ohm stereo or 4 ohm mono for CH1 ~ CH4 and 1 ohm 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-3500.1D, RP-4500.1D 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 headunit’s ground contact. all grounds should be common. 
  @ Check Rca Jack, then repalce with new one or reroute Rca Jack.
  @ Engine noise is caused by poor grounding of amplifiers, headunit, other components, battery or
  alternator, so please check all grounding connection.

POOR BASS RESPONSE

  @ Please check speaker cables and reverse polarity.
