5. TROUBLE SHOOTING
NO SOUND ( NO OUTPUT )
@ Please check all connections, cables' rounting, short & voltage
@ Please check the fuses , If they are blown, please replace with new one.
@ Please check whether speakers work well, you can test speakers by connecting to another amplifier
PROTECTION
@ Please check overload, overheat ( thermal ), short and voltage, DC offset.
@ Minimum working impedance is 1 ohm for 1100.1 & 2100.1.
2ohm stereo or 4ohm bridged for 300.4 & 1000.4.
@ If amplifiers are shut down due to heat, they will be on some minutes later aer cooling down.
Please make beer airflow and no obstruction around amplifiers for thermal protection.
@ All amplifiers working voltage is 9V ~ 16Volts.
@ When over 4V DC comes into amplifiers, then, they will be DC protected.
Check whether amplifiers work aer removing RCA-Input.
If amplifiers work, then check DC by checking RCA-input .
When DC is over 4V at input, try by rep12V source unit .
DISTORTION & NOISE
@ Readjust input level and check the speaker quality at another amplifier.
Replace poor quality speakers with good quality ones.
@ Check amplifiers and headunit’s ground contact. all grounds should be common.
@ Check Rca Jack, then repalce with new one or reroute Rca Jack.
@ Engine noise is caused by poor grounding of amplifiers, headunit, other components, baery or
alternator, so please check all grounding connection.
POOR BASS RESPONSE
@ Please check speaker cables and reverse polarity.
