INSTALLATION
CONNECTION RECOMENDATIONS
TROBLESHOOTING
Thank you for purchasing an amplifier.
We strongly recommend using the services of a professional installation studio
to install the amplifier. The correct configuration of the system and the qualifications
of specialists will allow you to maximize the potential of your amplifier, avoid unpleasant
situations, as well as eliminate connection errors and possible malfunctions.
Each channel of your amplifier
is rated to load from 2Ω to 8Ω when
connected in stereo.
When using bridged mode,
the minimum load impedance should be
3Ω for subwoofer and 4Ω for full range
speakers. Operating with a low load
impedance will not damage the amplifier,
but the device will likely overheat,
causing the thermal protection circuit to
shut down the amplifier. When the
cooling radiator cools down, normal
operation will resume. Long-term operation
of the amplifier under these conditions
is highly discouraged and will shorten
its service life.
Most car speakers are manufactured
with 4Ω impedance. When two such
speakers are connected in parallel,
we will get an impedance of 2Ω,
which is not recommended
for bridging your amplifier.
Simptoms Possible problem Recomendations
Distorted signal
Not enough
bass / treble
Battery fuse blows
Defective speaker system Check the functionality and
connection of the speakers.
Repair or replace them.
The polarity is reversed
when the speakers
are connected.
Check polarity and
reconnect if necessary.
Incorrect settings and
settings of the amplifier
filters
Change the crossover settings
until you achieve the sound you want.
The speaker impedance
is too low.
Check the impedance of the speakers.
It should not be less than 2Ω
in stereo or 4Ω in bridged mode.
Short circuit in the power
wire or incorrect connection
Check the power cable connections
and correct if necessary.
Fuse less than necessary. Replace with the correct fuse.
The fuse on the amplifier
is smaller than required.
Install the correct fuse.
Amplifier fuse blows
Check the power cable connections
and correct if necessary.
Too much current Check the impedance of the speakers.
It should not be less than 2Ω
in stereo or 4Ω in bridged mode.
Install the correct fuse.
Insufficient supply voltage
of the amplifier.
Should not be less than 11.3V
Check the voltage at the power
terminals of the amplifier.
Check if the connection
is correct and secure.
Incorrect settings and settings
of the amplifier filters
Change the crossover settings
until you achieve the sound you want.

Simptoms Possible problem Recomendations
Power cables are not connected. Check the power cable connections
and correct if necessary.
Defective speaker system Check your speakers
and repair or replace them.
The speaker impedance
is too low.
Check the impedance of the speakers.
It should not be less than 2Ω
in stereo mode and not less
than 4Ω in bridged mode.
The speaker terminals or
cables are shorted
to vehicle ground.
Check the integrity and
connection of the loudspeaker
connections if necessary.
Speaker cables are not
properly connected to
the amplifier
Check if the speaker cables
are connected properly
and correct if necessary.
Loose or poor connections
at the amplifier/source input/
output connectors.
Check signal cables and connections,
replace if necessary.
Connect the positive (+ 12V) cable only after all other cables have been connected.
The negative cable must be connected to the vehicle body exclusively by bolting.
The connection point must be free of paint and reliably protected from corrosion.
Loose power connections can cause unstable operation and damage to the amplifier.
The device turns on when + 12V is applied to the “REM” terminal. This terminal is low-current
and does not require connection with a cable of the same cross-section as positive or negative.
An acceptable wire is 18-16AWG (0.75-1.5mm2). The standard color of the control cable is blue.
Be sure to use a fuse on the positive power cable that is at least the same as the fuse on
the amplifier. amplifier. Install the fuse as close to the car battery as possible, but no further than
40cm from the positive terminal.
When operating the amplifier at maximum output power, it is recommended to use at least
8AWG (8mm2) cables. The cross section of the positive and negative cables must be the same.
For this, the models of power cables PCC-508R / B, PCS-308R / B are suitable.

In bridged mode, the signal must always be applied to both amplifier inputs. If the amplifier is used as the left or right channel
of a sound system to increase power, Y-adapters must be used.
