Your Soundigital amplifier needs the correct cables and
.
electrical system
Th e protection fuse/circuit breaker
must be installed at a max distance of
.
30cm (1 foot) from the battery
Minimum capacity of the battery 265Ah
Recommended capacity of the battery
Fuse/circuit breaker size
0 AWG/50mm²
Size of recommended cable
Use good quality cables (copper if possible) for the
connections to the amplifier.
Unplug the negative (-) terminal of
the battery before proceeding with
any electrical installation in the
vehicle to avoid fire starts, wounds
or damage to the amplifier.
Installation Tips
The ground cable should be the shortest possible and
should be connected to the chassis of the vehicle.
The surface should be sanded at the contact point to
create a clean, metal-to-metal connection between
the chassis and the termination of the ground wire.
Remove de paint between
the terminal and chassis
Keep the RCA cables together, but away from the
power or the audio output cables and away from
electric equipment such as electronic fuel injection
centrals, electric engines, etc.
Never connect or disconnect the
RCA cables with the amplifier on,
b e c a u s e i t m a y d a m a g e t h e
headunit or the amplifier.
When passing cables through metallic walls, use
rubber grommets to avoid damage to the cable and
short circuits.
Choose a proper place to install the amplifier and
avoid blocking the side ventilation panels.
Securely mount the amplifier so that it does not come
loose in the event of a collision or a sudden jolt to the
vehicle. Avoid mounting it on metallic parts of the
vehicle, because it may cause an earth loop (you
might have noise issues).
Be careful when drilling holes in
the vehicle. Verify if you're not

drilling holes in the fuel tank,

brake lines or electrical cables of
the vehicle.
Use speakers accordingly to the power and
impedance of the amplifier. Verify if the adjustment
filters can be used to increase the performance of the
equipment.

impedance under the nominal
impedance of the amplifier or you
may damage it.
The Soundigital amplifiers are micro controlled and
have an electronic monitoring of all of their functions,
offering useful information to the user through their
LED's.
Blue LED
- When constantly on, indicates the amplifier is working.
- When the audio is cut off and it blinks 10 times, it
indicates the current is under 8.9V or over 16v.
Red LED
- When it blinks during the audio reproduction, it
indicates the input tension is under 9.5 volts.
- When the audio is cut off and the led is constantly on, it
indicates the amplifier is in protection due to high
temperature. Turn the amplifier off until it gets to its
working temperature.
- When the audio is cut off and the LED blinks, it means it
is defective and must be sent to one of our technical
repair centers.
Yellow LED
- During the audio reproduction, it makes the sound
distortion monitoring. When it turns on, the speakers
are receiving distorted signal. So, you should turn down
the amplifier's gain or the headunit volume.
- When the audio is cut off and it blinks 10 times, it
means a short-circuit or low impedance in the audio
output.
