Investigate the layout of your vehicle thoroughly before drilling or cutting.  
Take care when you work near the gas tank, gas lines, hydraulic lines, electri-  
cal components and electrical wiring. Do not use the equipment unmounted.  
Attach this system securely to prevent damage, particularly in the event of an  
accident or aggressive driving. Do not mount the system so that wire con-  
nections are unprotected or are subjected to pinching or damage from nearby  
objects. Before connecting or disconnecting power connections at the system  
power terminals, disconnect the +12V DC wire at the battery end. Confirm that  
your source unit and other equipment are turned off while connecting the input  
terminals. If you need to replace the power fuse, replace it only with a fuse  
identical to the provided fuse. Using a fuse of different type or rating may result  
in damage to the system, which is not covered by the manufacturer’s warranty.  
Do not install any product where it may be subjected to excessive heat, moisture  
and dust or where it may be repeatedly kicked, brushed or bumped. Make abso-  
lutely sure that the terminals for the products are connected to the proper inputs  
and outputs from the music source. Never run the wiring on the outside of the  
vehicle or under it where it can be damaged by road hazards or any moving  
parts of the vehicle. Use existing wire channels, sills, panels and molding strips  
inside the vehicle to hide the wiring for safety and a neat appearance.
