4. Connect the front right ("+") speaker output of the amplifier to the positive terminal of the right speaker. 5. Repeat the same for the rear channel speaker connections. + L - + R - BRIDGE BRIDGE + L - + R - FRONT REAR FOR BRIDGED (MONO) Note: For bridged mono mode, 1. Connect the front left positive ("+") of the speaker. 2. Connect the front right negative ("–") of the speaker. 3. Repeat the same for the rear channel. 4. Make sure that ALL RCAs (front and rear left/and output will suffer.

PLEASE DOUBLE CHECK THE CONNECTION BEFORE TURNING THE SYSTEM ON. Figure 10: Stereo Connection 11 COUSTIC.COM CONNECTING AMPLIFIER Note: Power cables are as important as battery capacity. Use only high quality power gauge size AWG 8 (AWG 4 for the 481QE) or larger TOO BIG OF A POWER/GROUND Run the power cable through the interior terminal and connecting the other end to Be sure not to run the power cable together with the audio cables your audio system. If possible, run audio cables other. Never route these wires underneath the vehicle body. It is also advisable to install a circuit breaker/fuse This would effectively lower the risk of the power cable catching fire should circuit occur in the audio system. A circuit breaker or fuse with 50% of the main batteries’ larger in circuit breaker or fuse value means that you have Fuses on the amplifier DO NOT protect the amplifier, they protect the car. CONNECTING AMPLIFIER GROUND WIRE TO THE VEHICLE Find a good ground spot on the vehicles chassis and remove the paint contact point. Attach the ground wire to that contact point and connect ground wire to the GND terminal of the amplifier. TERMINALS, LUGS AND CONNECTORS High current terminals, lugs and/or connectors are also required to ensure a safe and sure electrical connection and conduction. CONNECT THE AMPLIFIER REMOTE CONTROL Connect the remote REM terminal of the amplifier to the remote output terminal of the source unit to establish amplifier remote on/off through the power on/off of the source unit. If the source does not provide a remote output, connect to its power antenna lead or other switched 12-volt source, e.g. ignition switch. RECONNECT THE BATTERY GROUND TO THE VEHICLE CHASSIS Double check all the previous installation steps, in particular, the wiring and component connection. If everything is in order, complete the installation by reconnecting the battery ground to the vehicle chassis. OPTIONAL REMOTE SUBWOOFER GAIN CONTROL (R S) If the optional remote subwoofer level control (model R S) is used, connect the plug of the R S to the port on the end panel of the amplifier.

The objective of input sensitivity adjustment is to match the output of the source unit with the input of the amplifier. The output voltage of individual source units can vary. For example, some source units have an output of 200 mV and others have 5 Volts or more. To cater to these variations, the QE amplifier has an adjustable input sensitivity level that ranges from 100 mV to 5 volts. Adjusting this control requires some experimenting. Basically, you want all the gain at the beginning of the system, NOT at the end (amplifier). Turn your headunit UP and keep your amplifier gains at the minimum possible setting (counter-clockwise). This will give you the best sound and signal-to-noise ratio. Besides better sonic reproduction, proper input sensitivity also helps to prolong the reliability span of your amplifier by eliminating excessive internal temperature generated by incompatible source unit output and amplifier input. Note: Turning the input gain UP does NOT indicate MORE power. Just MORE noise. The input gain control IS NOT a power control. REMEMBER that the input gain control has n...
