overview: BOSS OX4.400 Onyx 1600W 4 Channel Full-Range Class A/B Amplifier
The Boss OX4.400 Onyx 4-Channel Full Range Class A/B Amplifier delivers an outstanding 1,600 watts of power to your car's sound system. Processing such as variable low pass crossover and variable bass boost allows you to customize the sound to fit your wants.
The lowest impedance accepted by this amplifier is 2 ohms. Amplifiers that are 2 ohms stable produce more power resulting in more volume. This amp can comfortably power speakers or subwoofers with all channel(s) being used at a load of 2 ohms.
Class A/B amplifiers are known for their ability to produce great quality sound while performing more efficiently than pure Class A amplifiers. Boss has developed a specific linear circuitry that further reduces distortion while increasing both sound quality and power output.
Bridging combines channels of a multi-channel amplifier to get more power or flexibility out of it. For instance, on a 4 channel amp, channels 1 and 2 could be used normally for your speakers, and channels 3 and 4 can be bridged for more power to a single subwoofer. A 2-channel amp can also be bridged to power a single subwoofer.
MOSFET stands for Metal Oxide Semiconductor Field-Effect Transistor. MOSFETs are used either as a switch or to amplify a signal. MOSFETs are superior to other FETs, because they require less current to operate, which makes them better suited for car audio.
An amplifier with both high-level and low-level inputs provides flexibility by allowing you to build an audio system using virtually any standard factory or aftermarket source unit. High-level (speaker level) inputs accept the signal from the speakers, while low-level (RCA) inputs accept the signal from the pre-amp outputs of the source unit.
Variable Bass Boost allows you to adjust the low bass within the boost range to just the way you like it.
Variable Gain Control lets you balance the amps output with the speakers or subs the amp is driving. Matching gain will lead to distortion and to little will lead to clipping.
If the amplifier gets too hot, the thermal protection circuit turns the amp off and allows the amp to cool down before turning it back on. If a speaker fails causing an electrical short, the protection circuit will automatically cut the output and remain in that state until the short is resolved. These safety features give you peace of mind knowing the amplifier is constantly monitoring conditions to protect itself.
