Audiobahn A4KDN 4000 Watt Mono Amplifier

POWER EFFICIENCY
Audiobahn’s series of mono-block Class D amplifiers are specifically designed to provide raw power to drive subwoofers. These amplifiers utilize digital switching, which is a highly-efficient method for increasing power output while drawing less power from your vehicle’s electrical system. The application of this technology also gives Audiobahn’s Class D amplifiers the stability to operate at impedances as low as 1 ohm and still remain cool enough to utilize smaller heat sinks and outer chassis.

DUAL COOLING FANS
Regardless of how stable an amplifier is, heat deteriorates its functionality; keeping the amplifier cool is essential in preserving its longevity and power output. All Audiobahn Class D amplifiers feature dual cooling fans, which increase airflow to critical components on the circuit board’s surface area and help maintain the amplifier’s optimum operating temperature. Audiobahn has also designed the Class D amplifiers with chassis exhaust venting and side-rail fins to help eliminate harmful heat from sensitive inner components.

CLIPPING INDICATOR
When an amplifier is operating outside of its output threshold it can produce square waves or DC current, which can be harmful to subwoofers. This damaging circumstance is known as clipping. Audiobahn has included a digital clipping indicator on all Class D amplifiers to help ensure that you get the maximum performance out of your amplifier without sending any damaging signals to your subwoofers.
