Audiobahn makes amplifiers for car stereo systems, along with other products. Their line of amplifiers is built with a protect mode, which is designed to prevent the amplifier from becoming damaged. Speakers are rated to carry a signal measured in watts and ohms. The watts and ohms load must match the specifications for the amplifier, or a spike in the circuit will occur, causing the Audiobahn amplifier to jump into its protect mode. Any improper grounding, or none at all, will cause the Audiobahn amplifier to move into protect mode. Mounting the amplifier directly to a metal surface is often the cause. The car battery may have problems holding a charge. Faulty leads or leaking cells will cause problems in the circuit that feeds power to the stereo system, which will trigger a protect mode response from the Audiobahn amplifier. The alternator can also cause circuit problems across the car's electrical system. This will also bring about a protect mode response from the Audioban amplifier. Improper function of other parts of a stereo system, such as equalizers and subwoofer boosters, may overload or short-circuit the system. This will in turn cause the Audiobahn amplifier to default to protect mode.Wrong Speakers
