What Is a Sub Amplifier?
An audio amplifier is a power control that is connected to the speakers of a stereo system. A subwoofer amplifier is a special unit that is designed for a mono signal to a sub woofer speaker. This type of amplifier is most often used in cars and other high-fi home entertainment systems that use special subwoofer speakers.
There are many types of audio amplifiers used today. These are typically divided into different class types and channel outputs. A subwoofer amplifier only requires a mono signal, which is available in class D type amplifiers.
Installing a subwoofer amplifier is a moderately complex process. It requires a few basic electrician tools and some rudimentary knowledge of stereo equipment. The amplifier is typically connected to an auxiliary output located on the stereo receiver. The outputs of the amplifier are connected directly to the subwoofer speakers used by the receiver.
A subwoofer amplifier requires a clean power source to ensure the system is adequately powered at all times. Home units are typically plugged into external power strips that protect the amplifiers from power surges. A car unit should be attached directly to the battery with a heavy-duty wire to ensure clean power is delivered directly to the amplifier unit.
A car stereo sounds much deeper with a subwoofer and a subwoofer amplifier. This high-end audio equipment gives a car stereo more punch with heavy bass music. Passengers of vehicles nearby these types of stereos can actually feel the sound and vibrations of a car subwoofer.
Most car subwoofer amplifiers are designed for a car trunk or under a seat. Car audio service professionals are well equipped to install this type of audio component. Car subwoofer amplifiers should be connected directly to the car battery. This connection requires special heavy gauge wire that runs from the amplifier to the car battery. This installation may require some light drilling, which is why professional installers typically do it.
An amplifier is a complex electronic device that converts electronic energy into more powerful output signals. This is done through basic electronic transformer technology. A subwoofer amplifier is made specifically for subwoofers, which only detect frequencies below 100hz. These amplifiers use frequency filters that capture and energize those low-frequency signals.
Many home theater audio systems have built-in sub woofer amplifiers. These theater units have a special subwoofer connection that is designed to power and transmit signals directly to a subwoofer speaker.
