• Smart-Engage™ Auto-Turn-On - An auto-turn-on circuit is included within the amplifier. A remote turn-on wire is not necessary when connecting the amplifier’s high-level input to a high-powered source unit (car stereo). The amplifier will automatically turn on when music is received through this type of connection. Note: Smart Engage™ is only active on the left input. 4. Input Sensitivity – The Input Sensitivity switch is used to set the proper input voltage range: X1 POSITION: 100mV–1V (Typ

Installation Mounting Place your Thunder amplifier at the predetermined mounting location. Use a felt pen to mark the exact position of the mounting holes on the mounting surface. Set the amplifier aside. With a sharp, precise blade cut small circles in the carpet and padding around the four marks denoting your mounting holes to expose the metal underneath. Use a center punch to make an indentation in the metal to ensure that you drill the exact position for the screws. Note: Please use co

Running two amplifiers strapped will require “gain matching.” This will require source material that includes test tones and volt ohm/multi meter. Please see “Adjusting the Gain Controls” Note: Please pay attention and make sure the speakers or woofers are the correct IMPEDANCE (OHMS) BEFORE attaching to the amplifier. 3. Power Terminals – Please take proper measures during installation to protect the power wires as best you can. For example, when running the power cable from the vehicle’s ba

X1 POSITION: 100mV–1V (Typically for RCA Input) • Setting for Factory (OEM) Source Units: To check the amount of voltage that is present from the source unit, take a multi meter, or a volt/ohm meter, on the AC setting, (range from 100mV up to 10 volts) attach the positive and negative leads directly to any exposed speaker. It will not matter if the polarity is correct, it will read the same amount of voltage. X10 POSITION: 1V–10V (Typically for Speaker Level Input) Note: It is important n

• Setting the Frequency: Begin listening for the loudest musical spot or range within the bass range of your sound system. Adjust the center frequency to match this point. For most systems, the best center frequency adjustment will be between 40-50Hz. Use 45Hz (12 o’clock setting) as a starting point and adjust up or down gradually. • Setting the Boost/Cut: Once you determined the loudest musical spot or range within the bass range of your sound system, start cutting until the response is
