Tools and materials you need

WARNING !

• Screwdriver

• Electric drill, 3 mm / 0.12” carbide drill bit

• Mounting screws

• Power wire min. 35 mm² / 2 AWG

• Ground wire min. 35 mm² / 2 AWG

• Speaker wire min. 2 x 4 mm² / 11 AWG

Please note!

• As a precaution it is advisable to disconnect the vehicle’s battery before making connection to the +12 Volts supply wiring

(see owner’s manual of your car for further information).

• Please use great caution drilling your trunk. Your gas tank and brake lines can be damaged by puncturing with your drill bit –

this could cause damage or failure of your cars operating systems.

• Never pass wires over sharp angles. It is recommended to buffer the power supply of the amplifier with an additional

capacitor (power cap) min. 1 F to guarantee a stable operation voltage.

High powered audio systems in a vehicle are capable of generating "Live Concert" levels of sound pressure. Continued exposure to

excessively high volume sound levels may cause hearing loss or damage. Also, operation of a motor vehicle while listening to audio
equipment at high volume levels may impair your ability to hear external sounds such as; horns, warning signals, or emergency vehicles,
thus constituting to a potential traffic hazard. In the interest of safety, Consumer Electronics recommends listening at lower volume levels

while driving.

Before beginning the installation, consider the following:

a) If you plan to expand your system by adding other components sometime in the future, ensure adequate space is left, and

cooling requirements are met.

b) If your radio is equipped with preamplifier outputs (RCA), it is advisable to use them.

Mounting your amplifier

Planning your system

a) Select a suitable location that is convenient for mounting, is accessible for wiring and has ample room for air circulation and

cooling.

b) Use the amplifier as a template to mark the mounting holes, remove the amplifier and drill 4 holes. Then mount the amplifier

with the mounting screws.

Chose a mounting position where all electric wires are protected from being damaged by sharp edges, heat or other conditions. +12Volt
DC electrical connections must be fused on the battery side. Make sure your radio and all other devices will be turned off while conn ection
your system.

If you need to replace the power fuse, replace it only with a fuse identical to that supplied with the system. Using a fuse of different type or
rating may result in damage to this system which isn’t covered by the warranty.
