7.
Connect the power and the ground wires to the amplifier.
** Only after this step should you install the fuse at the battery**
8.
Connect the remote wire (blue wire on most head units) from the head unit to the “TURN ON”
connection of the amplifier. Now is a good time to turn on the amplifier for the first time. Make
sure it turns on properly and does not go into protection.
9.
With the amplifier turned off, connect the speakers to the amplifier making sure the polarity
(+ and -) are correct.
10.
Connect the RCAs to the amplifier. On a RMA 500.1 amplifier the “SLAVE OUT/IN” connections
are to connect multiple amps in parallel. The white end of the RCA cable will go into CH1 and
CH3 and the Red end will go into CH2 and CH4 on a RMA 500.4 amplifier.
11.
Now you are ready to play your stereo system for the first time. It is best to leave the “GAIN” all
the way down at first. Start with the head unit volume low and work your way up.
12.
This amplifier is set to a standard setting and may need some adjustment. Take your time and
make only one adjustment at a time. It may take some time to fully adjust your system. During
this time your amplifier is drawing current from the battery. You should check the battery voltage
from time to time and recharge it if it gets low. The battery’s voltage can affect the way the ampli
fier performs.
13.
You have now completed the install of your new RMA Marine Amplifier. Thank you and enjoy.
Protection Codes
This amplifier is equipped with an advanced diagnostic system controlled by the microprocessor. In the
event that this unit goes into protection for any reason it will flash the status light found on the control
end of the amplifier. The different sequences indicate the “Code” for faster trouble shooting.
End Panel Bicolor LED: Default behavior is to have the panel light green:
Code 11:
Thermal Protection
The amplifier has reached its maximum safe operating temperature
● ● ● ● ● ● ● ● ● ● ● ● ● ● ● ●
Code 12:
Short Protection
The amplifier has detected a short circuit and shut down to avoid damage
● ● ○ ○ ● ○ ● ○ ○ ○ ○ ○ ○ ○ ○ ○
Code 13:
Repeated Short
The amplifier is detecting a constant short circuit condition and will not turn back on until it is resolved
● ● ○ ○ ● ○ ● ○ ● ○ ○ ○ ○ ○ ○ ○
Code 14:
