Amp Smarts:

The amplifiers are devices that take a small audio signal and a pre-amplifier, a power of your battery, and that tells the drive as a audio signal to the speakers great.

The most important advice I can give is to buy a lot of energy. To get the cleanest sound, it is absolutely necessary to buy as much energy as you can afford.

Here are some terms you need to know when evaluating car audio amplifiers.

Power: A watt is a measure of thePower. Power is the ability to do the job. In the case of amplifiers, the work is moving to a speaker. The amplifiers come in all power ranges of 20 watts per channel up to thousands per channel. When it comes to amps, Watts describes two ways:

RMS: An amp that can power: 75W RMS x 4 CH @ 4Ω 14.4
This means that the amplifier of 75 watts into 4 channels with 4 ohm speakers is capable of 14.4 V and tension. The amplifier is capable of providing that power if all theseConditions are met at all times. The truth is that even if you fail to comply with the design of its system to all these conditions, it is at all times. Speakers Impedance '(measured in ohms, or Ω) change constantly while operating. Amplifiers not necessarilly put out the same power all the time or, if for example a low track is playing against a much more relaxed.

When you buy an MPA, look at its rated power as a marker for the ability of amplifier into place, probably put out at allTIMES.

However, I must also say that the qualification of an amplifier RMS a piece of information to try to determine a power amplifier.

CEA Compliant: This is (hopefully) will be the industry standard for determining a power amplifier. So you can accurately compare two amps to each other because they know they have been tested under the same conditions. To see why this is a good thing, click here …

MAX
Directly under the RMS number of amps, youamplifier see a "MAX" rating. It is often double the number of RMS. The MAX rating is pure junk. Never heed the maximum score, since only shows what the power amplifier in a laboratory setting. This type of environment may not be reproduced in the car, and therefore an assessment is misleading. The maximum number of amplifier proably about 50% more than the RMS. Never buy an amp into the number of max. Ok, and, finally, because it makes you look like a fool never, ever say your ampA 1000-watt amplifier, since it is a label 1000 Watt max, especially if you bought your amp at the Swap Meet. 1000-watt amplifiers are big and heavy.

Anyway, in short, never buy an amp in it Rating Max.

CEA Compliant:) (CEA = Consumer Electronics Association this specification (if your amp it contains) is a new assessment. The objectives of this assessment is to provide a useful reference for amp comparison. In the "bad times" could claim amplifier manufacturers quite independentPerformance they wanted without specifying the test procedures. Changes in number of CEA. The CEA compliant power indicates how much energy can be expected if the following criteria are met: 14.4 V, 4 Ohm speakers and 1% distortion. You can now fairly compare two amplifiers to each other because they know that they tested in the same way. Sense? No? Well, looks like this: If an amp has a CEA compliant output power of 100 watts per channel, you know that the amplifieressentially equal to another amp with the same CEA rating. You can not compare this amp to another amp that is rated at 100 watts / channel RMS.

I am a big fan of this evaluation. Finally, there is a uniform standard for ratings of the power amplifier output. If an amplifier does not contain this specification, the manufacturer, probably trying to hide something.

Bridging: Many stereo and 4 channel amplifier, you can "bridge". What makes a bridge to link two or four channels in aInto two parts. This allows you to allocate more energy for a speaker, a subwoofer. This is a very useful feature for someone who has a stereo amp around, but everyone wants to use its power to drive a single speaker. There is nothing wrong with supplements, and is often used for subwoofers.

Crossover: Many amps have a simple crossover built in. Basically, it's a switch that has three positions: high pass, low pass, off. Highpass can, in principle, anyto pass the higher frequencies. This is useful if the amplifier is the driving force mids and tweeters. The low pass can reproduce only the lowest frequencies. This is useful when a subwoofer amplifier is the driving force. Off means that all frequencies are sent to the speaker.

Bass Boost: Some amps have a circuit that is activated when an impulse to low. It is not essential, and I do not normally use in my own system.

Frequency Response: This specification tells you what frequenciesthe amplifier is responding. Higher frequencies are treble, lower frequencies are bass. The human ear can perceive, from 20 Hz to 20,000 Hz (also known as 20 kHz). Most amplifiers can reproduce this frequency band with ease. Some go beyond that. Do not worry, because the CDs often contain all the data in this area, even if they did not listen! Some people talk of harmony, and do not know if it's true or not. But whateva. Read more about this debate elsewhere.

Channel: Amplifiers haveChannels, which basically says how many consumers will be built. Load = speakers, so a two channel power amplifiers two speakers.

Classes:

Different amplifiers have different designs) to reach all the same (length of the music signal to do so, but in different ways. The manner in which the amplifier is intended to be known as the class of "." There are 4 main types of classes, and occasionally funny. really do not know the technical differences between them, butnever mind. We are installing amps, not designing them!

A – Very good sound quality, very inefficient, uses boatloads of power, and most of the waste heat.

B – Good sound quality, moderately effective, consumes much energy, waste, about half of them in the form of heat. Some "crossover distortion" present

A / B – Combination of classes A and B. In small quantities used in the class from the amplifier. At higher volumes, uses the class B of the AMP.

D- (So-quality sound, but played under very well), highly efficient, uses minimal power, wastes very little.

Other classes: Whatever. They exist. I do not know if it sounds better. Their ears are the best judge.

THD: This stands for "distortion", but the D is all you need to take. Obviously, the fewer the better. You do not want your amps producing distortion and send it to the speakers! Cause noise and speaker damage. TheExperts say that a score below 0.1% THD is inaudible, meaning that there can be noticed. But remember that distortion travels through all components, and is reinforced by all. Thus, low distortion amplifiers and other high distortion in the system to reproduce the distortion.

S / N Ratio: A measure of how the sound of silence amplifier backround. This specification is measured in dB, and the higher the S / N, cleaner sound.

Speaker Check: This feature allows you to contactthe amplifier) to your system via speaker cable (instead of RCA cables. This function is useful when adding an amplifier to your factory stereo system you want.

Preamp Outputs: This feature allows you to deliver an RCA cable to connect the amplifier to an amplifier with the second signal. This feature is useful if you have an amp amplifier seconds without wires all the way from the unit head to want to add. In addition, you can import additional power amplifier to drive the head to add that can only have one set of RCAPre-outs.

Bass Remote Control: This feature allows the amplifier's bass output without control to adapt to the amplifier. You can control the Assembly is smart, and adjust the bass remote.

HOW IS THE AMP is most appropriate for your system:

How many channels of your system?

Connecting channels.

Features you want

Crossover:

Entries:

Loudspeaker (level III)

RCA pre-amplifier (AS level)

How many channels is? The drive We talked about the areas of hi-fi, so you need, how many speakers you choose the drive. Suppose you want to create an intermediate system with 6 speakers. I thank everyone for all the Step 6 of this amplifier with a "real". You can go several ways: you can buy a 6-channel amplifier-amplifier or a 5-channel, and the power of the entire system. That makes life easier if you keep the installation simple and clean like. You can also power the speakers with multiple amps: A monkey, a 4-channelMaybe even three stereo amplifiers. If desired, you can really feel I could bi-amp your component speakers, including your amp to 3 amp 4 am to 5 pm!

One way you can be creative with the facility shall be saved. If you use the power of 2 or more boats in a stereo amplifier, you can save, or combine the two channels into one. From there you can get their boats in parallel or serial cable to the proper ohm load. It's an easy way to several speakers at a poweramp.

To save money, you can always refrain from installing an amplifier for the rear speakers. I have many times just power from the display unit. When I listen to music without rear passengers, I can only return the unit to the front, faded and left me with the amplified front speakers.

You need an amplifier to have a cross?

Crossover be useful when changing subwoofer. Most amplifiers can reproduce the full range of human hearing. However, when you install subs, we only wantto play the bass. If the amplifier has a crossover, you can turn it on, and essentially tell the amp to only send to the subwoofer. Since submarines can play only reproduce bass, why waste energy sending the subwoofers amp frequecies not be? LUNACY I tell ya!

Tickets

Spokesman: This is a high level inputs because the signal has already increased considerably. Get an amp with high level inputs if you have an integrated amplifier with a factory head unit.

RCA: This iscalled low-level inputs because the signal is enhanced. These inputs are RCA-style and are preferred because they produce less noise. This is the best option if you use a head unit aftermarket.

So, now you are really informed about amps. Do not worry. You can thank us later!
