Troubleshooti ng
NO SOUND
• The speaker cables or RCA plugs are not connected correctly.
• Check to see if the LEVEL control is on the lowest setti ng. Check the amplifi er fi lter controls.
NO SOUND. RED ALERT PROT BLINKING:
• The speakers or cables are defecti ve. Check speakers, cables and connecti ons.
POOR SOUND QUALITY (DISTORTIONS):
• The speakers are overloaded. Decrease and readjust the volume level (see entry
“LEVEL (LEVEL CONTROL)”
)
WEAK BASS:
• Speaker cables (+) and (-) are switched or the speaker is out of phase (see entry
“INSTALLATION OF THE SPEAKER
OUTPUTS”
).
• Also check audio control adjustment.
ENGINE, HORN, TURN SIGNAL, INTERFERENCE:
• Use suppressing/insulated cables on the spark plugs.
• Use capacitors on the alternator, horn and igniti on.
• Run the shielded input cable away from any other cables, as they are parti cularly prone to interference.
• Install a separate power source (+12V) for the sound system. Use a fuse/circuit breaker 30 centi meters from the bat-
tery asa safety precauti on.
• Ground the amplifi er properly. Remove paint from the chassis at the selected point and connect the wire using a
grounded terminal. In order to prevent rust, insulate it with paint. Do not loop the ground. Avoid using multi ple grounds.
If possible, use a star connecti on in which all the grounds run from a single point.
Troubleshooti ng
NO POWER
• The power cables are not connected correctly (terBAT, GND and REM). Verify that all the connecti ons have
electrical and mechanical contact.
• The fuse/circuit breakers are defecti ve or blown. Replace them, making sure that the replacements are the correct
ones!

Installati on of the Speaker Outputs
The speaker cables should be polarized (marked) so that you can easily identi fy which is positi ve and which is negati ve.
Minimum gauge is
11 AWG
. Keep the cables well insulated and avoid metal parts as these may damage the insulati on.
