D Series amplifiers are compact amplifiers with full size features. The D4.100a is a bridgeable four channel amplifier with a total output power of 640 watts. If you need solid power and clean sound, but don’t have much room to spare, this amp is perfect for the application.

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.
