WARNING
Make sure you choose a suitable place to mount the unit. The position should
be completely dry with a good circulation of air, and from a mechanical point
of view very stable.
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 3Q for subwoofer use, and 4Q 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 expectancy.
Most 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 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.
Series/parallel wiring
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. 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).
