Mounting instructions
As a precaution, it is recommended to disconnect the vehicles battery before mounting (also note the vehicles manual!)
The power supply wire (+12 V) has to be protected within max. 20 cm / 8” by a main fuse holder with matching fuse value
(Main fuse value has to be equal to the sum of values of the fuses of each connected device)
If necessary, replace a defective fuse by a new one with identical value
Never drill a hole to the vehicles gas tank or brake lines, to wirings or any other important vehicle part!
Never pass wires over sharp edges or vehicle parts
Keep the wiring away from the antenna and electronic devices contributing to radio reception
Install the power supply wiring locally separated from the speaker wiring
The amplifier contains a temperature protection circuit that turns the device off in case of overheating. After a certain cooling
time the amplifier will turn on again automatically. To avoid heat build-up, it´s necessary to provide sufficient air supply for
the amplifier cooling. Therefore, never cover the surface of the heatsink entirely.
The amplifier should not be mounted on a strongly vibrating part or surface (e.g. subwoofer enclosure)
If a pre-amplified output (RCA) is available (on the head unit) it is recommended to make use of them
WARNING !
Powerful car audio systems are able to create extremely high SPL similar to real 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.
