Troubleshooting

●  Before removing the amplifier, refer to the list below and follow the suggested procedures. 

●  Always test the speakers and confirm that they are wired correctly first. 

●   If in any doubt get help from a qualified auto electrician.

Amplifier Will Not Power Up

●   Check for good ground connections. Ensure Ground cable is connected directly to bare  

  metal and not a painted surface. 

●   Using a multimeter check that remote terminal has at least 10V DC.

●   Using a multi meter check that there is battery voltage on the positive terminal.

●   Check all fuses.

●   Check that the protection light is not illuminated. If it is lit, shut off the amplifier for thirty  

  seconds and then turn it back on.

Protection LED Illuminates When Amplifier Is Powered Up

●   Check for shorts on all speakers wires. (IE no speaker wires should be joined together and  

  no speaker wires should be touching the cars chassis)

●   The amplifier is designed to shut down automatically when the units temperature goes  

  above 80 degrees. If the amplifier feels very hot then this may be the reason for the  

  amplifier not starting.

●  Remove the speaker wires and reset the amplifier. If the protection LED still comes on then  

  the amplifier is faulty. This damage may have been caused by either failure to follow these  

  setup guidelines or abuse. 

Amplifier Gets Very Hot

●   Check the minimum speaker impedance for the amplifier is correct. 

●   Check for shorts on all speakers wires. (IE no speaker wires should be joined together and  

  no speaker wires should be touching the cars chassis)

●   Check that there is good airflow around the amplifier. In some applications an external fan  

  may be required.

Blown Fuse(s) 

●   Check both positive supply and ground for shorts.

●   Check that the positive wire is connected to the positive terminal on the amplifier.

●   Check that the negative wire is connected to the ground terminal on the amplifier. 

●   Ensure that the correct rated fuse is fitted

Distorted Sound

●   Check the gain control is not set at too high a level. If the speakers sound distorted turn the  

  down the gain until the sound is clear. 

●   Check that all crossover frequencies are correct. See setup section for more details. 

●   Check for shorts on all speaker wires.  

●   Check all speakers are wired correctly. With the correct polarity being observed on each  

  connection. 

Set Up Section

To correctly set the gain control of the amplifier to match that of the source (headunit) use the 

following setup routine:

Turn the gain control to minimum on the amplifier.

Ensure the bass boost is set to 0 dB.

On the headunit set all crossovers to flat and both bass and treble to zero.

Turn up the source (headunit) to approx 3/4 volume.

Very slowly turn up the gain on the amplifier until distortion can be heard in any of the speakers 

or until the volume reaches an uncomfortable listening level when this is reached turn down 

the gain control slightly.

The gain control is now set. 

The setting of the crossover will depend on what kind of speaker you are installing.

For a subwoofer it is recommended that the crossover is set to Low Pass and the frequency is 

set to match that of the speakers specifications.

For a pair of full range speakers it is recommend that the crossover is set to Flat. The two 

frequency controls will then have no effect on the amplifiers output and the speaker will receive 

a full range signal. However, using the high pass crossovers will allow more control of your 

speakers. By removing the bass (low frequencies) the speakers can perform at higher volumes 

with less distortion. 

Note: The smaller the speaker, the less bass it can handle. Adjust the crossover to get the 

most and best sound from your speakers. The easiest was to do this is by limiting the amount 

of bass you feed them

For a pair of speakers with a passive crossover it is recommended that the crossover is set to 

High Pass and the frequency is set to match that of the speakers specifications. 

Note:

By using the crossovers correctly you will not only lengthen the life of your speakers but 

you will also get better performance from them. To optimise your setup seek the advice of a 

professional installation engineer or visit your local EDGE audio dealer.
