Mounting instructions

Recommended wiring

• As a precaution, it is recommended to d isconnect the vehicl es battery before mounting (also note the vehicles manua l!)

• The power s upply wire (+12 V) has to be pr otected within max. 20 cm / 8” by a ma in fuse holder with matching fuse value

(Main fuse va lue has to be equa l to the s um of va lues of th e fuses of each co nnect ed devi ce)

• If necess ary, replace a defective fuse with the identical value only

• Never drill a hole to th e vehicles gas tank or b rake li nes, to wirings or any other im portant 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

• Lay the power supply wiring always separated from speaker wiring

• The amplifier contains a temperature protection circuit that turns the device off in case of overh eating. After a cooling time,

it will turn on again automatically. To avoid heat buildup, sufficient air supply for cooling must be provided. 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 ( at the head unit), it is recommended to make use of them

Powerful car audio systems are able to create extr emely high SPL s imil ar to real live concert level s. Permanent exposure to excess ively 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 m usic at appropriately low volume lev els while driving.
