system planning

Proper system planning is the best way to maximize your PowerPlate’s™ performance. By planning your installation carefully you can avoid situations where the performance or the reliability of your system is compromised. Your authorized a/d/s/ dealer has been trained to maximize your system’s sonic potential. Your a/d/s/ dealer is a valuable resource in helping you with your system design and installation.

speaker requirements

Each channel of your PowerPlate™ can easily drive 2 speaker loads when used in the stereo mode. When a channel-pair is bridged, the recommended minimum load impedance is 4 for subwoofer use, and 4 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 4 impedance. Connecting two such speakers in parallel will result in a 2 impedance load as seen by the amplifier. Some a/d/s/ subwoofer models feature a dual 4 voice coil design. Connecting these voice coils in parallel will result in a 2 nominal impedance, which is not recommended for use with bridged channels of your PowerPlate™.
