The Dual Electronics DA604D High Performance Series MOSFET Class D Digital Four Channel Car Amplifier with 400-Watt Peak Power is a force to be reckoned with. Your Class D Four Channel Amplifier was engineered with specific linear circuitry that improves sound quality and power output while reducing distortion and refining efficiency for unrivaled sound superiority. We anticipated continuous use of your car amplifier so we engineered a High Current & Efficient MOSFET design that enables you to have insurmountable power at your disposal. Your proficient MOSFET design enables you to have 400 Watts of Peak Power, 200 Watts RMS via 2 Channels @ 4 Ohms (Bridged), 85 Watts RMS via 4 Channels @ 2 Ohms and 60 Watts RMS via 4 Channels @ 4 Ohms for unrivaled sound superiority.

When our engineers were designing your high performance DUAL car stereo amplifier they wanted to make sure that you were always able to adjust your amplifier to fit your music needs. This model includes a pass through RCA connection, which will allow you to link two high performance series amplifiers together for double the outputs and streamlined efficiency. We also added High & Low Level Inputs with Auto Turn-on, which allow high-level inputs to accept speaker output signals and low-level inputs to accept preamp output signals.

But we didn’t stop there; we also included: Variable High-Pass Crossover (35Hz – 250Hz @ 12dB/octave), Variable Low-Pass Crossover (35Hz – 250Hz @ 12 dB/octave), Variable Bass Boost @ 45Hz (0dB – 12dB) & Variable Gain Control for ultimate control over your music experience.

We cannot stress safety enough here at Dual Electronics so we designed a built-in short circuit protection via a thermal and DC offset safety for your amplifier.

Built for the Road Ahead and backed by our 1 Year warranty that guarantees a hassle free experience with excellent customer service.
