Introduction 

 
Your Autotek STEALTH amplifier has been designed to give you very high performance, and valuable 
features, at a reasonable price. Take the time to read over this brief set of instructions, and you will get full 
enjoyment from your system. 
 
Installation 
 
The quality of the installation will affect system performance and reliability. You may wish to contact a 
dealer or professional installer. The amplifier is generally mounted in the rear trunk area but can be 
mounted in any convenient area such as beneath a seat. Please be sure to locate this unit where you have 
reasonable air circulation and protection from any hazard with moisture. When considering the mounting 
location you should minimize the length of the power supply and speaker leads. It is important to ensure 
that the cooling fans or the heat sink are not against a panel or a surface preventing air circulation. Mark the 
location fro the mounting screw holes by using the amplifier as a template. Drill #29 or 9/64” diameter 
holes at the marked locations and firmly fasten the amplifier in place with the mounting screws supplied in 
the accessory kit. (Refer to Fig. 1) 
 

Caution 

 

Before drilling or cutting any holes investigate the layout of your automobile thoroughly; take care when 
working near the gas lines or hydraulic lines and electrical wiring. 
 

Warning 

 
This power amplifier has a protection feature to prevent any damage form misuse or faulty conditions—
excessive heat, short circuited speakers or overload. If the nit senses one of the above conditions, the 
protection indicator will light and the system will shut down. To diagnose the problem turn all levels down, 
all power off and check the installation for possible wring mistakes or shorts. In the event the amplifier 
shuts down due to excessive heat under adverse conditions simply allow time for the unit to cool down at 
which time the protection indicator will not light.
