Mounting instructions
•
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 enough for the required current!
•
If necessary, replace a defective fuse by a fuse with identical quality and value
•
Never drill holes to the vehicle´s gas tank, 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, enough 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 loosened 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.
