11. STALLATION STEP 4 INSTALLATION AND MOUNTING 1 AMPLIFIER LOCATION The SA amplifiers employ highly efficient circuitry and a unique Chassisink design to maintain lower operating temperatures Additional cooling may be required if the amplifier is located in a tightly confined area or when driving especially low impedance loads at extremely high levels When mounting the amplifier it should be securely mounted to either a panel in the vehicle or an amp board or rack that is securely mounted to the vehicle The mounting location should be either in the passenger compartment or in the trunk of the vehicle away from moisture stray or moving objects and major electrical components To provide adequate ventilation mount the amplifier so that there are at least two inches of freely circulating air above and to the sides of it SWITCHES Set Input and Crossover switches to the appropriate positions see pages 18 21 Be sure to re install the plugs included with the amplifier MOUNTING THE AMPLIFIER a Using the amplifier as a template mark the mounting surface b Remove the amplifier and drill the holes c Mount the amplifier to the surface using the provided hardware 4 WIRING a Route and connect the audio signal and remote turn on cables to the amplifier from the source unit b Carefully run the positive cable from the amplifier to a fuse or circuit breaker within 18 inches of the battery c Then connect the fuse or
