TROUBLE SHOOTING
This section provides you with a catalogue of amplifier symptoms and their probable
causes and solutions.
Before consulting this listing, make sure the vehicle's electrical system is working
properly by verifying that other electrical items (headlights, windows) still function
correctly.
SYMPTOM
PROBABLE CAUSE
No audio
Low or N.C.Remote
Turn-on connections
Blown fuse
Power wires not connected
Speakers blown or not connected
Distorted Audio
Input sensitivity not set properly or
damaged speaker
Low turn-on voltage
Audio level low
Mute circuit on head unit is on
Speakers wired with wrong polarity ,
Louspeakers lack bass
causing cancellation of bass
(while working)
frequencies
External fuse broken
Incorrect wiring or short
Whining noise on audio
Amplier picks up alternator
while engine running
noise
Ticking noise on audio
Amplier picks up radiated spark
while engine running
noise
SOLUTION
Check remote turn-on voltage at amp and head
unit
Check ground and battery connections
Replace fuse after checking
Use VOM or DVM to measure speaker coil
impedance.
Check cable wires of loudspeaker.
Replace suspected component. Reduce input sensitivity.
IMPORTANT: Never run amplifier without having
speakers connected
Check turn on voltage as described on p.5
Check electrical system for low voltage.
Ground connection not o.k.
Check polarity of wires from ampliers to each speaker
as dened by the system design
Check battery voltage voltage at amplier during
operation
Refer to electrical installation and check installation steps.
Replace fuse.
Install an in-line noise filter and eventually
replace the battery
Check all grounds and other cables (esp. autobody
cables)
Do not place cables near parts that are connected to
ignition. Eventually check spark plug wires.
