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.

Speaker requirements
Each channel of your amplifier can easily drive 40 speaker loads when used in the stereo mode. When a channel-pair is bridged, the recommended minimum load impedance is 30 for subwoofer use, and 40 for full range operation. Although operation with lower impedances is not likely to cause immediate damage to the internal circuitry, the unit will most likely overheat, causing the thermal protection circuitry to shut down the amplifier. When the chassis cools down, normal operation will resume. Continuing to operate the amplifier under these conditions is not recommended and will reduce its life expectancyMost speakers designed for car audio operation are 40 impedance. Connecting two such speakers in parallel will result in a 20 impedance load as seen by the amplifier. Some 40 subwoofer models feature a dual 40 voice coil design. Connecting these voice coils in parallel will result in a 20 nominal impedance, which is not recommended for use with bridged
channels of your amplifier.

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 + 12 Volts to this terminal This terminal dose not draw heavy current like the two power terminal so a thinner connecting wire is acceptable. Standard 18 GAUGE is fine and the standard colour is yellow. If the radio is equipped with a power antenna control wire, it can drive this terminal. If the power antenna wire is already in use, you can still splice into it. With this method, the unit will turn on automatically with the radio. Use the power supply lead with a fuse attached whose value is the same as original fuse. Place the fuse in the power supply lead as close as possible to the car battery. During a full power operation, Maximum current will run through the system. Therefore, Make sure the that the leads to be connected to the+ 12v and GND terminals of the unit respectively must be larger than 10-Gauge (AWG. 10).
