D Series 5 Channel Amplifier


Search Authorized DD AUDIO Dealers Near You    

D Series amplifiers are compact amplifiers with full size features. The D5.350 is a five channel amplifier designed to power an entire audio system while taking up minimal space. It has a four channel section with a total output power of 560 watts and a 350 watt dedicated sub section. Precision tuning is made easy with variable bandpass crossovers and LED clipping indicators. Installation is made easier with single side controls and connections, input mode switches, and auto turn-on options.  For boat, bike, and ATV applications conformal coated internal circuitry and corrosion proof switches offer increased moisture resistance.   Even though the D Series amplifiers are very compact they still employ set screw power and speaker terminals, discrete output sections, and heavy duty anodized aluminum heatsinks. This ensures power management is proper from input to output, increasing both in-use stability and long term durability.
