• Re-adjust the Input Level Control to better suit the input signal.

Weak output

If the noise is a “whine” whose pitch follows the engine speed, confirm 

that the amplifier and any other signal sources (head unit, equalizer, etc) 

are properly grounded.

If the noise is a “clicking” or “popping” noise whose rate follows the 

engine speed, this usually means that the vehicle is equipped with resis-

tor spark plugs and wires, or that the ignition is in need of service.

Check the routing of the speaker and input wires to make sure they are 

not adjacent to wires which interconnect with lights and other accesso-

ries.

If the above steps fail to improve or clear noise interference, the system 

should be checked by a authorized RE Audio Dealer.

Noise in the audio

Confirm that all terminal strip connections are secure and tight.

Check the “BALANCE” control on the head unit (or other source) to verify 

that it is set to its mid point.

If you are using the low-level RCA input, reverse the input plugs at the 

amplifier (switch the R with the L). If the channel which is silent switches 

to the other side, the problem is either in the head unit/other source or 

the connecting cables.

Only one channel works

Confirm that all terminal strip connections are secure and tight.
Check both in-line and built-in fuses.
Confirm that the audio signal source (car radio, equalizer, etc) is 

connected and is supplying output signal. To check if the amplifier is 

supplying signal, unplug the RCA cables from the signal source (but 

leave them plugged into the amp) and briefly tap the center pin of each 

of the disconnected RCA plugs with your finger. This should produce a 

noise (feedback) in your speakers.



No Output

Before removing your amplifier, refer to the list below and follow the 

suggested procedures. Always test the speakers and their wires first.
