TROUBLESHOOTING
Overall sound effect good, but bass
abnormal (more bass at the two
extreme settings of the balance
control than at the center setting).
SYMPTOM
PROBABLE CAUSE
No power
When the engine is running, the
audio system has a whining
noise that remains unchanged or
disappears with the increase of
audio volume.
When the engine is running, the
audio system has a whining noise
that increases or decreases with
the volume of all program sources
(wheather radio, tape or CD).
When the engine is running, the
audio system has a Whining noise
that increases or decreases with
the tape mode volume ONLY.
Obvious distortion at low volume.
●
Check all the ground, B+ and remote cables for tight connection.
●
Check all fuses.
●
Use a Volt/Ohm meter to check all power wire connections to see
if the system is rec 12V.
●
Check if the crossover B+ power input is connected directly to
the battery.
●
Check the battery voltage; if low, recharge or replace it.
●
Check if the crossover has a good ground connection (i.e.
Whether the ground wire is making good contact with a bare
metal spot of the vehicle chassis).
●
Check all ground connections of the entire system for good
contact with bare metal.
●
Check for speaker short: Disconnect speaker wire from amplifier;
test speaker and wire with a Volt/Ohm meter, if there is speaker
and metal contact, slightly enlarge the speaker mounting holes,
if there is a short in the speaker wiring, replace the entire speaker
wire or re-insulate any exposed wire with electrical tape.
●
Check all power wires to see if they are all connected directly to
the battery.
●
Check all the ground connections of the entire system for good
contact with bare metal of the vehicle chassis.
●
Check if the source unit and the crossover arc grounded at the
same reference point.
●
Install a 10 amp in-line filter on the red power wire of the
crossover
●
If the whining noise persists, check the alternator diodes and
the voltage regulator.
●
This is commonly known as “radiated noise. It is NOT caused
by the crossover and thus is beyond the scope of this manual.
Please contact your local retailer/installer for assistance.
●
Output level of various channels not compatible, refer to section
titled SYSTEM CHECK.
●
The subwoofers are" out-of- phase" with each other, thus
cancelling the bass when the balance control is at the center
position. Check the wiring from the amplifier to the subwoofers
(positive “+”to positive “+”and negative“-” to negative" -”).
Motorboating:
The crossover power indicator
going off repeatedly when
the audio system is on
The crossover heats up quickly
even when the audio system
is at moderate volume.
