Thank you for purchasing a Cadence Q Series amplifier. Over the past years, the technology used to create audio amplifiers has grown by leaps and bounds. We have tens of thousands of satisfied customers still using our first generation Ultra Drive amplifiers which are more than 10 years old. Our competition is satisfied with just continuing to build the same units year after year without thought for improvement, but not Cadence.
All the terminals on the amplifier are solid brass and gold plated for high conductivity and minimum impedance loss. The power and ground terminals are extra large and capable of accepting 4-8 gauge wire. The speaker terminals can accept 16 gauge wire. When wiring the amplifier, be sure to strip just enough wire that fits into the terminal so that bare wires do not touch each other, or the amplifier chassis and cause a short circuit.
Cadence Q Series amplifiers feature "ARVA" circuitry in their power supply. This circuit constantly monitors the output stage and under high current demands will adjust the power supply rail voltages so that enough power is available for peak situations. The "ARVA" also improves the damping factor of the amplifier when playing low impedance mono loads. Cadence Q Series amplifiers have tighter sounding bass reproduction thanks to this unique circuitry.
The Q Series amplifiers are supplied with built-in fuses, never replace the fuse that the amp came with, with one of a larger value. We suggest you construct a Red wiring harness with 2 additional fuse. One fuse should be located near the car battery. This fuse near the battery offers protection against damage from short circuits to the car chassis between the battery and the amplifier. A second fuse closer to the amplifier offers additional safety to the amplifier itself.
Once the system is operational, the first thing to do, is set all crossover points to approximate settings. In the case of the basic subwoofer system Low Pass filter crossover at 100 Hz or so. Set the Bass Boost equalizer controls to 0 dB Now you should set the amplifiers LEVEL adjustment. The knob accessible on the top of the amplifier marked Input Level adjusts the input sensitivity from 150mV to 5Volts.
Choose a convenient mounting location with unobstructed airflow. The Q amplifiers feature four plastic mounting tabs located at the amplifiers four corners. You will need to remove the light-up acrylic panel and the chrome trim plate to access these mounting tabs. Using the supplied screws, gently mount the amplifier in to position. Do not over tighten the screws. All Q series amplifiers come with three molded acrylic covers in red, blue and orange. The cover is held down with four thumb screws.

Please note that the minimum impedance load for single Cadence Q Series amplifiers is 2 ohm stereo and 4 ohm mono bridged. Lower impedance loads will cause overheating and may damage the amplifiers. Do not mix different type and different impedance speakers in the series and/or parallel combinations, as unequal power sharing and acoustic outputs will result.
