TROUBLE SHOOTING
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 contin-
ues 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. 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.
