Answer 2 is totally correct.
Answer 3 is totally confusing to me, and suggests the contributor doesn't know much about capacitors. I have been an electronics hobbiest for over 45 years, and have had some paying jobs in electronics manufacturing, and have never heard of such a thing.
She is correct in that capacitors are electrical storages devices [DC ONLY by the way], BUT only for very small amounts of power. Even the new SUPER CAPACITORS DO NOT HAVE THE POWER STORAGE CAPACITIES to make ANY contribution to the solution to this problem. A whole pickup bed full of the new supercaps might give an amplifier system, as described, operate for up to a minute or two.
Although the question does not address whether the unacceptable battery drain is occurring when the engine is operating, or off. Answer 2 alludes to this problem in that BIG, POWER HOGGING AMPS USE A LOT OF POWER, AND that power has to come from somewhere.
Usually, most vehicle alternators [if the engine is kept running] are capable of "keeping up with" audio amplifier systems.
If the amp is being used with the vehicle engine OFF, then a MUCH LARGER battery [or several] is needed. If, with the engine running, the battery is STILL being drained [and the alternator is not defective], then a larger alternator is needed.
If the power demand is greater than the largest alternator output, then you just have too much amplifier for a vehicle.
IF you STILL want to use THAT amplifier in THAT vehicle, then I suggest that you:
1. Get a gasoline powered PORTABLE AC [alternating current] GENERATOR SET, AND
2. Get a POWER INVERTER [changes alternating current to direct current] RATED with a CONTINUOUS power output GREATER than the power draw [demand] of your monster amplifier.
I don't think you're going to have to worry about this problem for very long anyway. At the volume levels required to draw that much current, you are going to be DEAF anyway.

AF means audio frequency. Audio Amplifiers can be subgrouped as voltage amplifiers (or pre-amplifiers) and power amplifiers. The voltage amplifier will raise the level of level of the output of a microphone from say 1 mV to 500mV or 1V. The power amplifier will be the interface between this and the load, which is a speaker. The resistance of the speaker is often 4 ohm or 8 ohm. You cannot have a speaker with 1k as resistance! As such to get say 8W output, an amplifier providing 8V will have to pump 1 amp into an 8 ohm speaker. Thus power amplifiers will have to drive a lot of current into the load. Voltage amplifiers cannot do this. A power amplifier sometimes just has unity voltage gain, but has ability to drive a lot of current into the load. Typical power amplifiers are operated in class B, where for 50% of the signal swing, one transistor provides current, and for the other 50%, the other transistor in a class B provides current into load. Class B amplifiers have cross over distortion, But this can be overcome by pre-biasing, or making the stage operate as class AB. The power amplifiers can also be used to power low resistance loads such as a step up transformer.
Cap amplifiers can provide an enhanced audio experience as they often are able to reproduce a wider range of audio frequencies compared to many stock car stereos.
Physical vibrations of speaker cones or metal plates by electromagnetic coils connected to the audio output AC signals from the audio amplifiers.
Car amplifiers can be as loud as those which have more than 1000 watt power. The Loudest TL-1021 series from WIKIO are some of the loud car amplifiers. Audio Assault also comes out with car amplifiers of 1000 W.
Audio amplifiers use no impedance matching. We use bridging. That means low output impedance and high input impedance.
Frequency response, gain, noise, and distortion
Audio amplifiers are electric circuits which work to amplify a weak signal, such as the signal from microphones, tape player and several other devices. It amplifies the signal to a level capable of driving a loud speaker.
The definition of audio electronics is the part of science that is dealing with reproducing and recording devices through another device amplifiers.
An audio amplifier boosts sound levels. Audio amplifiers typically contain transistors, though the transistors are often packaged inside ICs (Integrated Circuits). A transistor is an electrical device that allows a small amount of voltage or current to trigger a larger level of voltage and/or current. So an amplifier reproduces the sound at a higher amplitude or strength. Of course, there are some tube-type amplifiers that are still in existence. Those are rare and it is hard to find the tubes. Vacuum tubes were what was in use before transistors. There are different types of audio amplifiers. Radios and televisions contain audio amplifiers to be able to drive the speakers. Once the audio signal is extracted from the radio waves and passes out of the detector stage, it is too weak to drive a speaker. Sound boards in computers are capable of driving headphones directly, though not always at a comfortable volume. If you want the volume to be louder, or you want to listen through speakers, you would do best to get a set of amplified speakers. They contain an amplifier inside, and that is why they require batteries or a power cord.

Audio components can be connected with speaker wire for signals from amplifiers. Brand doesn't matter, although a thicker wire will have less loss than a thinner wire. For the best audio, optical or coaxial digital cable for digital audio signals. For the best video, HDMI is the current standard for connection between high-definition sources and receivers and video displays.
A: Immense from an analogue computer to ADC to DAC to audio. Their use is probably the same as digital usage.
I have a friend who took his car speaker and attached his amp controls to it. So yes. I have a friend who took his car speaker and attached his amp controls to it. So yes.
No. Not only is it illegal to amplify a CB radio beyond the FCC permitted four watts, but stereo amplifiers and linear amplifiers work in very different ways.
