Our series of mono block Class D amplifiers by Audiobahn are designed to provide raw power to drive subwoofers. These amplifiers utilized digital switching, an effective method for increasing power from your vehicle's electrical system. This technology gives Audiobahn's Class D amplifiers the stability to operate impedances as low as 1 ohm and still remain cool enough to utilize smaller heat sinks and outer chassis. DUAL COOLING FANS: Audiobahn Class D amplifiers feature dual cooling fans which aid in the increase of airflow to critical components on the circuit board's surface area. This helps maintain the amplifier's optimum operating temperature which preserves its longevity and power output. In addition, our Class D amplifiers are designed 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 is known as clipping. As a result, all Class D amplifiers from Audiobahn are made with a digital clipping indicator to ensure maximum performance out of your amplifier without sending any damaging signals to your subwoofers.
