General 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 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, 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.
