DESCRIPTION

The D3 Series Amplifiers provide a wide range of power and features that make them an excellent choice for a variety of car audio sound system configurations.

D3 Amplifiers use an unregulated power supply for good control of output power. This power supply design helps yield maximum power transfer with a minimum of heat loss.

On board noise filtration is used to keep unwanted noise from leaking into the system from the amplifier. Each D3 amplifier comes complete with thermal, short, and load protection circuits as well.
