To make low volume sound into HIGH volume sound.
audio amplifier
In audio look at an amplifier. It will be always a voltage amplifier.
A headphone amplifier is a type of audio amplifier. Instead of an amplifier that's designed to push through audio signals to speakers, a headphone amplifier is designed to work with headphones. These are common in devices such as MP3 players.
It's entirely possible to use four 70W speakers with a 150W amplifier but the method will depend on the speakers and the amplifier specification. We will assume that the amplifier will deliver up to 150W per channel, so two speakers will be used on each channel. If the amplifier is rated to drive a 4 ohm load, then two 8 ohm speakers can be wired in parallel and connected. In this instance, take care NOT to drive the amplifier too hard. It will overdrive the speakers at about the same time that it will begin to show a distorted output. This is a condition that can easily damage speakers so be very conservative with the volume control. If the speakers are 4 ohm speakers, they can be wired in series to provide a total impedance of 8 ohms. If the amplifier is rated to deliver 150W into 4 ohms, then the total power to the speakers will be lower than to a single speaker. The benefit is that no speaker can be over-driven and there is a good amount of headroom for safety.
The amp for audio freq. is a AF amplifier. The RF amp is for radio freqs.
There are many downsides of using an amplifier for one's car audio system. Some downsides for using an amplifier for one's car audio system includes bothering those around them due to the noise and harming one's ears.
Because radio control relies on different frequencies. Since frequencies are involved in the process, an audio amplifier can be used to amplify alternating currents (currents that change), and it does the same job.
How do you replace the amplifier in a 2002 ml 500? i need to know where in the 2002 ml500 i can find the audio amplifier

In audio the input impedance of an amplifier is between 10 kiloohms and 20 kiloohms.
