General installation note
• 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 personnel of your vehicle´s manufacturer!)
• 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 or internal fuse value
(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 to 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 not 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.
• This amplifier has got a high- -level input option, however if a pre amplified output (RCA) is available (from head unit), it
is strongly recommended to make use of it.
