1. No power: Verify that the Ground, +BATT and remote 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 confirm 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 11-15volts. If the amp has 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 amplifier), check
output signal connections from the source unit and input signal connections at the amp.
Remove speaker wires and test for opens or shorts of speakers 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 amplifier).
Remove the speaker wires and test for opens or shorts of speakers with a digital
multi-meter set to the impedance setting. Gently push on the speaker with your ear close to
it. If it sounds scratchy then replace the speaker or consult a local 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 amplifier’s
input sensitivity.
6. Amplifier 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 amplifier installation
instructions for causes of high operating temperature). If the amp has good ventilation then
check the speaker impedance to verify that it is above the suggested load rating. With it
running,verify that you have more than 11volts 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.
