Weak Output
Readjust the input level control(s) to better suit the input signal.
Noise in the Audio
If the noise is a “whine” whose pitch follows the engine speed, confirm that the amplifier and any other signal sources
(head unit, etc.) are properly grounded.
If the noise is a “clicking” or “popping” noise whose rate follows the engine speed, this usually means that the vehicle is
equipped with resistor spark plugs and wires, or that the ignition is in need of service.
Check the rounting of the speaker and input wires to make sure they are not adjacent to wires which interconnect
lights and other accessories.
If the above steps fail to improve or clear noise interference, the system should be checked by a professional mobile
audio installer.
Precautions
•
Do not operate the amplif ier when it is unmounted. Attach all audio system components securely within the
automobile to prevent damage, especially in an accident.
•
Do nor mount this ampiif ier so thatthe wire connections are unprotected. or in a pinched condltlon or likely to be
damaged by nearby objects.
•
Before making or breaking power connections in your system, disconnect the vehicle battery. Confirm that your
head unit or other equipment is turned off while connecting the input jacks and speaker terminals.
•
If you need to replace the power fuse, do so only with a fuse identital to that supplied with the amplifier.
Using a fuse of a different type or rating may result in damage that isn’t covered in the manufacturer’s warranty.
