This is How You Build a Really Cool 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.

PA D4000.4 Features:

   - 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.

   - Protection—thermal, DC offset, reverse DC voltage and short circuit


   - Nickel-plated wire terminals & RCA connectors—ensure maximum signal


   - Front & rear level controls—adjust the gain of the front and rear channels to

     match the output voltage from your head unit.

   - Low-pass & high-pass frequency controls—enables you to adjust crossover

     overlap for better blending of speakers.

   - Front & rear BPF, FULL, HPF switches—selects full range, high pass filter,

     or bandpass filter to dial in your speaker blending.

   - Channel mode switch (ST/4Ch)—in the stereo position, the amplifier will

     send the same signal to front and rear channels.

   - Stainless steel hardware—used throughout and will not corrode in humid
