System planning Proper system planning is the best way to maximize your amplifier performance. By planning your installation carefully you can avoid situations where the performance of the reliability of your system is compromised. Your authorized dealer has been trained to maximize your system's sonic potential. Your dealer is a valuable resource in helping you with your system design and installation.
Power Connection Leads Notes on the power supply Connect the + 12V power input lead only after all other leads have been connected. Be sure to connect the ground wire of the unit securely to a metal part of the car. A lose connection may cause a malfunction of the amplifier. REMOTE: The unit is turned on by applying + 12Volts to this terminal This terminal dose not draw heavy current like the two power terminal so a thinner connecting wire is acceptable.
system 1: 4 channel mode ENG-3
system 2: 3 channel mode ENG-4
system 3: 2channel bridged connection ENG-5
