DD Audio D1100 (D class) power amplifier (mono).

DD Audio D1100 (D class) power amplifier (mono).

D Series amplifiers are compact amplifiers with full size features. 
The D1100 is a 1 ohm stable monoblock subwoofer amplifier with a total output power of 1100 watts. 
Precision tuning is made easy with variable bandpass crossovers and LED clipping indicator. 
Installation is made easier with single side controls and connections, 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.
