5. TROUBLE SHOOTING TIPS

NO SOUND ( NO OUTPUT )

1) Pls check all connections, cables' rounting, short, voltage at

and headunit

2) Pls check fuses ,If they are blown, pls replace with new ones.

3) Pls check whether speakers are functional. You can connect a AA battery to the speaker

terminals to see if there is any movement of the speaker cone.

PROTECTION

1) Pls check overload, overheat ( thermal ), short and voltage. DC offset

2) Minimum working impedance is 1 ohm for single

Quattro

minimum working impedance is 2 ohm stereo or 4 ohm mono

3) If

a short cooling period.

Please allow for better airflow and ensure there's no obstruction around the

thermal protection

Mono

has low and high voltage protection. Working voltage is 9V~16V.

Voltage lower than 8.5V or higher than 16V will cause the amplifier to go into protect.

5) When over 4V DC comes into

Check whether

series amplifiers are functional, then check DC by checking RCA-input L and R

When DC is over 4V at input, try by replacing headunit or source unit

DISTORTION

1) Adjust the input level and check the quality of the speakers. Replace low quality speakers

with upgraded ones.

POOR BASS RESPONSE

1) Pls check speaker cables and reverse the polarity of one channel

BUZZING SOUND

1) Check the amplifier and the head unit ground and ensure it has a good clean connection

2) Check the Rca jack and replace it if faulty or try rerouting it.

WHINING NOISE

1) Engine noise is caused by poor grounding of

components, battery or alternator, so pls check all grounding connection.

amplifiers are shut down due to overheat, they will start up again after

series amplifiers, then, they will be DC protected.

series amplifiers work after removing RCA-Input
