Do I need car amplifier even if I'm more concerned on vocals (sound quality) and not bass?

Question

I usually think amplifiers are for bass. What's the difference between 2 channels and 4 channels as far as sound quality is concerned?

Answer 1

1.)
Audio Amplifiers are built to bump sound signals up several notches. The main reason these have become vital is so that the signal is able to drive your speakers.

Depending on the rating of your speakers, and the environment in which you will be listening, you will probably need an amplifier if your player is not able to feed your speakers with sufficiently powerful audio signals.

Now, most players (tape, CD, or MP3) have enough power output to drive a wide range of speakers so it should not be difficult to try it out before you buy. But an amplifier will definitely give you a good margin to pay with.

Sound quality (since you mention it) does not necessarily deteriorate when you have an amplifier, but the amplifier makes noise (or other glitches) more audible.

Since you will be playing in your car, I'd probably recommend you give it a try without the amplifier if you have your system set up, then just see how well you like it. If your car is quiet and driving around in traffic does not spoil your experience, you just might not need an amplifier after all.

2.)
As far as quality is concerned, the number of channels does play a tiny role. Listening to music from 2 channels is a major improvement over mono, but listening to it through 4 channels can greatly increase your experience. 4 channels enable you to be immersed in the acoustic stage, and thus improving perception.

The greatest disadvantage with 2 channel systems in a car is that since you will be reasonably immobile in the car and relatively close to the speakers, it is not as easy to create a good audio environment for your music. Playing through 4 channels enables you to distribute sound much better in the cabin.

Any audiophiles out there could easily shoot down any of my points here, but I would still recommend you try out an amp, and a 4 channel system before buying one. It just might be the setup for you :-)

Answer 2

Head Units are not powerful enough to reproduce sounds with any fidelity or quality. In fact, the manufacturers purposely make the head units anemic for aftermarket sales of amps and accessories.

If affordable, I would go with the amp solution in 95% of the applications available. The 5% being DAD or MOM or Grandma's car, and they don't usually need Head Units outside of the factory jobs already installed.

If you do choose the amp solution, you won't be disappointed.

The 2 channel system refers to a lower end type of stock application; usually, front and rear stock type amplification. The four channel; usually 3 channels from the head unit and one dedicated channel to the sub woofers. Usually, and most important here: separate amps for the Base or subs. that are dedicated for low frequency effects and most often Mono in output.

Sound quality on the 2 or 4 channel amp differ in application, usage, head unit, speaker quality, wiring and media content all very important factors to consider.

So, it is a little more complicated than your question asks. Many factors are involved; too many parameters and variables to define the difference in reality. Hope this helped.

an amp on your highs will definatly make it sound alot better-louder and more crisp especially if you have after market highs with tweeters in the middle of them- no real sound quality difference on a 2 or 4 channel-its all wattage -a 2 channel just has two rca inlets and two speaker outputs-a 4 channel has 4 rca inlets and 4 speaker out puts-if you want good sound quality you need a cd player with multiple rca outputs so you can still fade it front to back and side to side to get maximum sound quality-if ya use a 4 channel amp you can wire all of your speakers up but you lose fader and theyre all gonna be the same volume-id get a cd player with front ,rear and sub out puts and run aftermarket speakers and base your amp on the speakers rms watts not max power-get 2-2 channel amps and match one to your front speakers rms(speakers are 100 watts rms get an amp thats 100 watts rms-for instance- a 600 2 channel is around 100-150 rms per channel-that means 100-150 watts per speaker-then match your speakers in the back the same way-and with seperate rca outputs you will be able to have a fader option-then if you want add subs later on you have an rca output for them too-once again match your amps rms to your speakers-all this will be very effective and have great sound quality-hope this helps ya

Answer 4

just like speakers, amps will clean up the sound alot. more so then one would think. the differnce in sound quality in a 2 or 4 channel amp is nothing. just get a good SQ amp like a. . .

Answer 5

You don't need one. If it's for vocals, you just need a good stereo and speaker set up. Amps just make things louder. An equalizer would be best.
