Super Efficient Class D Bridgeable 4-Channel Mobile Audio Amplifier

The PA D4000.4 amplifier is capable of bridging two full-range channels into a single full range channel with higher output power. For instance, one front and one rear channel will increase the output power from 125W per channel to 400W per channel (for a 4 ohm load). The most common hookups for the PA D4000.4 would be four full-range channels, two full-range channels and a bridged sub, or two bridged subwoofers.

Features:

  • Low THD, a high signal-to-noise ratio, plus wide bandwidth frequencies make the PA D4000.4 four-channel a superior choice for distortion-free power
  • Super-efficient class D design—Runs much cooler than conventional amps
  • High-speed MOSFET—Switching power supply
  • Toroidal transformers help keep the amplifier’s sleek design under 2-inch tall while ensuring plenty of clean, efficient power.
