7. Amplifi er shutting off and LED fl ashing off and on:

 This is an indication of low or 

high voltage at the +BATT or the remote portion of the amp. Test the +BATT and the remote 
portion of the amp with a digital multi-meter. If the voltage at either of these terminals is 
above 15 volts or below 11 volts, consult an automotive electrical specialist. If voltage is 
consistently below 11 volts, adding a one-farad StreetWires stiffening capacitor will solve the 
problem. 

8. Whining noise that increases with acceleration:

  This is what is known as a 

ground loop. To verify if the noise is being generated by a bad ground or the RCA cables, 
remove the RCA cables from the amp (make sure they are shielded from touching the chassis) 
and turn the system back on. If the noise persists, then the problem is ground related. If the 
noise stops, then it is being radiated into the amp via the RCA cables. If the noise is being 
radiated by the RCA cables, simply re-route the cables away from power cables– specifi cally 
the +BATT cable that is connected to the battery. If whining noise is ground related then 
confi rm that all ground cables are secure in the vehicle and free of corrosion. Please see the 
power and ground portion of this manual for correct system grounding 

instructions. 

MTX TECHNICAL SUPPORT 1.800.225.5689

1. No power:

 Verify that the Ground, +BATT, and remote cables are securely attached to the 

amp, the connection at the + terminal of the battery is secure, the remote turn-on is securely 
fastened to the source unit and that the in-line fuse at the battery is good as well as the fuse 
on the amp. If fuses are blown, replace them and attempt to power the amp back on. If fuses 
continue to blow, please see an authorized dealer. To confi rm that the amp is getting power 
at the +BATT and remote, use a digital multi-meter set to DC voltage, attach the negative 
terminal of the meter to the ground and the positive to the +BATT and then check the remote. 
The remote and the +BATT should have 11-15 volts. If the amp has a good ground, +BATT, and 
remote voltage and will not power on, please visit an authorized dealer or call the technical 
support number listed below for further assistance.

2. Power light on, no output:

 Turn the audio system off (source unit and amplifi er), check 

output signal connections from the source unit and input signal connections at the amp. 
Remove speaker wires and test for open connections or shorts with a digital multi-meter set 
to the impedance setting. Reconnect the speaker wires and test the system. If there is still no 
output, visit an authorized dealer or call the technical support number listed below for further 
assistance.

3. Amp turns on and shuts off:

 Turn the audio system off (source unit and amplifi er). 

Remove the speaker wires and test for open connections or shorts of speakers with a digital 
multi-meter set to the impedance setting. With your ear close to the speaker gently push on it. 
If it sounds scratchy then replace the speaker or consult an authorized dealer. Carefully touch 
the amp for temperature. If it is extremely hot then the amp is in thermal protection and needs 
to cool down. If thermal protection continues to be a problem, see an authorized dealer or call 
the technical support number below.

4. No sound from one side:

 Check the speaker connections, input connections, balance 

control on the source unit, and then check the speakers for shorts with the digital 
multi-meter.

5. Low sound from both radio and CD:

 Check the radio’s fader control and the amplifi er’s 

input sensitivity.

6. Amplifi er shuts down after long play times:

 If the light is turned off, then the amp is 

probably in thermal protection due to poor ventilation (see amplifi er installation 
instructions for causes of high operating temperature). If the amp has good ventilation, check 
the speaker impedance to verify that it is above the suggested load rating. With it running, 
verify that you have more than 11 volts at the +BATT portion of the amp and that you have 4 
gauge power cable and the proper fuse rating at the fuse holder near the vehicle 
battery.
