Amplifier

Amp Smarts
Amplifiers are devices that take a teeny tiny audio signal from the pre-amp some power from your battery, and pass it as a great big audio signal to drive speakers.
The most important piece of advice I can give to you is to buy a lot of power. To get the cleanest sound it is very important to buy as much power as you can afford.
Here are some terms you should know when evaluating car audio amplifiers.
Watt watt is a measurement of power. Power is the ability to do work. In the case of an amplifier's job is to move the speaker. Amplifiers come in all power ranges from watts per channel up to thousands per channel. When it comes to the two ways described watt amplifier
WHEN BUYING AN AMP IT CHECK POWER RATING AS A MARKER FOR S S AMP YOUR ABILITY rather than what is likely to put OUT ANY TIME.
But I also have to say that RMS amp rating is one piece of information to look for to determine the amp's power.
CEA Compliant Power Output This is hopefully going to be the industry standard for determining the power amp's output. It allows you to accurately compare two amps to each other because you know that they are tested under the same conditions. To see why this is a good thing click here ...
MAXbottom right amp RMS rating you will see the amp's MAX rating. It is often double the RMS rating. MAX rating is pure junk. Never pay attention to the max rating because it only shows what the amp is capable of in the lab. Such an environment can not be reproduced in the auto and because the ratings are misleading. An amp max rating is proably about more than RMS. Never buy an amp based on it's Max rating. Ok and the latter because it makes you look like a total jerk never ever say your amp is the watt amp because it has a sticker on it and max wattage ESPECIALLY if you bought your amp at the swap meet. Amp wattage HUGE and HEAVY.
Anyway in summation were never bought by that MAX amp rating.
I am a big fan of this ranking. FINALLY there is a uniform standard for amplifier power output ratings. If the amp does not include this spec, the manufacturer may be trying to hide something.
Bridging Many channel amp stereo and allows you to bridge. What do you do with bridging is combine two channels into one channel into two or four. It allows you to allocate more power to a single speaker as a subwoofer for example. This is a useful feature for someone who has a stereo amp lying around but they want to use all the power to drive a single speaker. There is nothing wrong with bridging and is often used for the subwoofer.
Bass Boost Some amps have circuits that when activated give a boost to your bass. It is not important and I usually do not use it in my own system.
Channel Amps have channels that basically tells you how much of a burden it was built to drive. Load two channel amp speaker so that the strength of the two speakers.
Class
Different amps have different designs that all achieve the same thing amplify music signals but achieve this in different ways. Manner designed amplifier called class company. There are main types of classes and sometimes eccentric. I do not really know the technical difference between them but that does not matter. We're just installing amps did not design them
A - excellent sound quality is not very efficient use of power and waste boatloads mostly in the form of heat.
B - Good sound quality is quite efficient to use a lot of power waste about half of it in the form of heat. Some crossover distortion
attend
A / B - Combination of classes A and B. At low volume amp using class majority. At a higher volume uses the class B of the amp.
D - So-so sound quality but bass excellent reproduce very efficiently using minimal power waste very little of it.
Whatever other classes. They are there. I do not know if they sound better. Your ears are the best judge.
S / N Ratio A Measure of how an amplifier silence backround noise. This spec is measured in db and HIGH s / n ratio cleaning your voice.
Speaker Level Input This feature allows you to connect the amp to your system through speaker cable instead of RCA cables. This feature is useful if you add the amp to the factory stereo system.
Preamp output feature allows you to connect the RCA cables to the amp to supply a second amp with the musical signal. This feature is useful if you want to add a second amp without running wires all the way from the head unit to the amp. Also allows you to add an additional amp to the head unit may only have one set of RCA pre-outs.
Remote bass control feature allows you to control the output of the amp without having to adjust the bass amp. You can mount any smart control and adjust the bass remotely.

How many channels will you drive We've covered the range stereo system so you need to determine how many speakers you're driving. Say you want to build an intermediate system with speakers. You figure you want to strengthen all of those who have a real amp. You can go a couple of routes you can buy the amp channel or channel amp and power your entire system. That makes life easier if you want to keep the installation clean and simple. You can also power your speakers with multiple amps A single-channel mono you could even use three stereo amps. If you want to be really fancy you can bi-amp your component speakers take you to calculate the amp and amp
One way that you can get creative with your installation is through bridging. If you want more power or dive on a stereo amp you can bridge or combine the two channels into one. From there you can wire your subs in parallel or series to get the right ohm load. It's an easy way to power a variety of speakers on one amp.
To save money you can always choose not to install the amp to the rear speakers. I often times just power them off of the head unit. If I listen to music without rear passengers I can just fade the head unit to the front leaving me with the amplified front speakers.
Do you need an amp to have a crossover
Input
These speakers are called high-level inputs because the signal is already highly amplified. Get amp with high level input if you integrate amp with factory head unit.
RCA's called low-level inputs because the signal is not highly amplified. This RCA input and styles are preferred because they produce less noise. This is the best option if you are using an aftermarket head unit.
