SAFETY PRECAUTIONS

Important Warnings to Take Note of BEFORE Commencing Installation
Damage Caused By Incorrect Installation or Usage is NOT Covered By Warranty.
PLEASE Take the Time to Read the Installation Notes Carefully.
To Validate the Warranty Please Ensure That the Unit is Installed by a Professional, VAT registered 
Car Audio Installation Company.

To avoid short in your vehicles electrical system, be sure to disconnect the battery cable before beginning installation.

The unit is intended for vehicles with a 12-volt battery and negative grounding. Before installing the unit in a recreational vehicle, 
truck, or bus, check that the battery voltage is 12 volts. 

Remove the two transport screws from the top of the unit before installation.

Be sure to connect the negative (-) speaker leads to the negative (-) speaker terminal. Never connect the negative (-) speaker leads 
to chassis ground. 
This unit is only designed for use with 4 speakers. Do not combine outputs for use with 2 speakers. Do not ground negative speaker 
leads to the chassis ground. 
Speakers connected to this unit must be high-power units with a minimum rating of 45W and impedance of 4 to 8 ohms. Connecting 
speakers with output and/or impedance values other than those noted there will result in damage to the head unit and the speakers. 

Check the condition off your speakers carefully - connecting the unit to old of degraded speakers may result in a fault which 
will damage the audio IC and invalidate the warranty. 

If this unit is installed in a vehicle that does not have an ACC (accessory) position on the ignition switch, the red lead of the unit should 
be connected to a terminal coupled with ignition switch ON/OFF operations. If this is not done, the vehicle battery may be drained 
when you are away from the vehicle for several hours.
