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.
There are many retailers where one can purchase car audio amplifiers. Edmunds, Best Buy, Amazon, Crutchfield and eBay all sell car audio amplifiers for people to purchase.
Two channel amplifiers, also known as stereo amplifiers. Examples of two channel amplifiers include manufacturers such as Planet Audio, Vibe Audio, MB Quart, Lanzar, Pyrimid and Boss to name a few.
Audio amplifiers are not able to employ others since they are inanimate objects.

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.
Carver Audio company offers many different audio products, ranging from mainly amplifiers, to cassette decks, CD players, tuners, preamps, speakers, etc.
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.

The cost of Cambridge Audio Amplifiers will differ depending on the exact model you wish to purchase. Something like the Azur 651A costs $800 well the Azur 351A costs $550.
The definition of audio electronics is the part of science that is dealing with reproducing and recording devices through another device amplifiers.
