General installation notes
•
As a precaution, it is recommended to disconnect the vehicles battery before mounting the amplifier. (Note:
For new vehicles, disconnecting the battery might cause various errors in your vehicle´s electric system that
can be cleared only by authorized service partners of your vehicle´s manufacturer! Please ask your service
partner first before disconnecting the battery!)
•
The power supply wire (+12 V) has to be protected within max. 20 cm / 8” by a main fuse holder with a
fuse value matching the recommendation for your amplifier
(Note: If there is more than one amplifier connected using this power wire, the main fuse value must be
equal to the sum of the recommended fuses of all connected devices. However, make sure the diameter of
your power wire will be sufficient for the required current!)
•
If necessary, replace a defective fuse by a fuse with identical quality and value
•
Never drill a hole to the vehicle´s gas tank or brake lines, to wirings or any other important vehicle parts!
•
Never pass wires over sharp edges or vehicle parts due avoid any kind of damage
•
Keep the wiring away from the antenna and electronic devices contributing to radio reception
•
Lay the power supply wiring always separated from speaker wiring to avoid disturbance
•
The amplifier contains a temperature protection circuit that turns the device off in case of overheating. After
a certain cooling time, it will turn on automatically. To avoid heat build-up, sufficient air supply for cooling
must be provided. Never cover the surface of the amplifier´s heatsink entirely
•
The amplifier should NEVER be mounted onto a vibrating part or surface such as a subwoofer enclosure.
This might lead to malfunction due to lose electrical parts inside the amplifier
•
Some amplifiers offer a high-level input option, however if a pre-amplified output (RCA) is available (at the
head unit), it is strongly recommended to make use of them.
WARNING!
Powerful car audio systems are capable to create an extremely high SPL level comparable to live concert levels.
Permanent exposure to excessively high sound levels may cause damage to or loss of the hearing.
Furthermore, operation of a motor vehicle while listening to audio equipment at high volume levels may impair your ability to concentrate
on road traffic and external sounds such as horns, warning signals or emergency vehicles. In the interest of general and own safety, it is
recommended to listen to music at appropriately low volume levels while driving
