• STOP USE IMMEDIATELY IF A PROBLEM OCCURS. Failure to do so may result in personal injury or damage to the
product. Return it to your authorized STEG dealer.
• HAVE AN EXPERT DO THE WIRING AND INSTALLATION. This product requires special technical skill and experience for
wiring and installation. To insure safety and proper function, always contact the authorized dealer where you purchased
the product to have it done professionally.
• INSTALL EACH COMPONENT SECURELY WITH SPECIFIED PARTS. Be sure to use only the included parts and specified
installation accessories (not included). Use of other than designated parts may damage this unit. Install the unit securely
so that it will not come loose during a collision or sudden jolt.
• ROUTE WIRING AWAY FROM SHARP EDGES AND MOVING PARTS. Arrange cables and wiring away from sharp or
pointed edges and avoid moving parts such as seat hinges or rails to prevent pinching or wear. Use loom protection
where appropriate and always use a grommet for any wiring routed through metal.
• NEVER RUN SYSTEM WIRING OUTSIDE OR UNDERNEATH THE VEHICLE. All wiring must be routed, secured and
protected inside the vehicle. Failure to do so may result in fire, injury or property damage.
• INSTALL EACH COMPONENT IN A DRY AND VENTILATED LOCATION. Avoid mounting locations where any
component of this product will likely be exposed to high moisture or heat without adequate ventilation. Moisture
penetration or heat buildup may result in product failure.
• REDUCE SYSTEM GAIN(S) AND SOURCE VOLUME TO MINIMUM LEVELS FOR INITIAL SOUND TUNING. Ensure
amplifier power is off before connecting signal cables and follow proper system gain setting procedures. Failure to do so
may result in damage to the amplifier(s), speaker(s) and/or other connected components.
• DO NOT OVER-DRIVE AMPLIFIER(S). Over-driving amplifier(s) into clipping will cause severe distortion that can
damage the connected speaker(s). Ensure all system gains and levels are properly set to minimize the chance for
amplifier clipping over the entire source volume range.
• DO NOT EXCEED SPEAKER POWER HANDLING. Make sure amplifier power output does not exceed the rated power
handling of the connected speaker(s) or component(s) and do not allow over-excursion. Failure to use appropriate
amplifier power, crossovers or level settings may result in product damage or failure.
• DO NOT DRIVE WHILE DISTRACTED. Any function that requires your prolonged attention should not be performed
while driving. Always stop the vehicle in a safe location before performing any such function. Failure to do so may result
in an accident.
• KEEP THE VOLUME AT MODERATE LEVELS WHILE DRIVING. Excess volume levels can obscure sounds such as
emergency vehicle sirens or road warning signals and may result in an accident. Continuous exposure to high sound
pressure levels may cause permanent hearing loss. Use common sense and practice safe sound.
•MAKE THE CORRECT WIRING CONNECTIONS AND USE PROPER FUSE PROTECTION. Failure to connect wiring
correctly with appropriate gauge and fuse protection may result in fire, injury or product damage . When replacing
fuse(s) in the unit, never exceed the specified rating. Ensure proper protection of all system power wiring and install an
external fuse (not included) with specified rating for each amplifier connected with the +12V lead at the battery terminal.
• D O NOT ALLOW CABLES TO BECOME ENTANGLED IN SURROUNDING OBJECTS. Arrange wiring and cables to
prevent obstructions when driving. Cables or wiring that obstruct or hang up on places such as steering wheel, brake
pedals, etc. can be extremely hazardous.
• DO NOT DAMAGE VEHICLE SYSTEMS OR WIRING WHEN DRILLING HOLES. When drilling holes in the chassis for
installation, take precautions so as not to contact, puncture or obstruct brake lines, fuel lines, fuel tanks, electrical wiring,
etc. Failure to take such precautions may result in fire or an accident.
• DO NOT UTILIZE OR CONNECT TO ANY PART OF VEHICLE SAFETY SYSTEMS. Bolts, nuts or wires used in the brake,
airbag, steering or any other safety-related systems or fuel tanks should NEVER be used for mounting, power or ground
connections. Using such parts may disable control of the vehicle or result in fire.
