Common Configurations For Amp Channels
Amp outputs are called channels. A 4 channel amp will have, you guessed it, 4 outputs. Generally, each channel can only handle one speaker. There are cases where you can hook multiple speakers to one channel. Those cases involve a good understanding of . and are somewhat rare in car audio systems.
Amps can come with any number of channels. These are the 5 most common configurations:
What Should You Consider Before I Buy The Best Bluetooth Car Amplifier
Bluetooth is an easy way to make hands-free phone calls and listen to music through your vehicle speakers. Here we have discussed some important factors to consider before buying best Bluetooth car amplifier.
The power rating of a car amplifier is important when choosing a car stereo. Power ratings range from 1 to 10. Most amplifiers have a rating of 6 or higher. Higher power ratings mean more volume and better sound quality.
RMS & PEAK VOLUMES:
The RMS is the average amount of power that comes out of the amplifier. If you listen to an RMS number, it will tell you how much power your amp has.
The peak volume is the highest level of power output that the amplifier can produce. If your amp has a peak volume of 100, that means that it can produce 100 times the power as an RMS number would indicate.

NUMBER OF CHANNELS:
Bluetooth car amps also have a great option for a different number of channels. You can select according to your choice or requirement. Ideally, Your car stereo amplifier should have at least two channels. This is so you can use two speakers at once. Lets know about a short introduction about different channel car amplifier and their features.
A mono channel will only let you hear one speaker at a time. Most amplifiers come with a mono channel. If your amplifier doesnt have a mono channel, you can buy one.

The Most Common Types Of 4
While most amplifiers can be classified into class A, B, AB, or D, we will focus solely on AB and D, since most car amplifiers fit into these two categories. There are also other variations, such as BD. Typically, other amplifier classes include characteristics from the main types of amps to boost performance.
- Class AB
Class AB amplifiers are a combination of class A and class B. They are much more efficient than class A amps but dont have as much distortion as class B amps. As a result, many car audio systems use these types of full-range amps. Essentially, the transistors have a constant current flowing through them, but when no signal is present, they reduce the amount of the current in the circuitry. Class AB amplifiers are analog.
- Class D
Class D amps rapidly switch the current on and off to the transistors. This results in a switched or pulsed output signal. These types of amps are very efficient however, the switching can cause distortion in higher frequencies. To combat this issue, amps will include a low-pass filter because lower frequencies dont experience the same problem. The power of class D amps makes them very popular in-car audio systems.

What Is A 4 Channel Amp
4 channel amps, as you may have already guessed, are extremely similar to 2 and 5 channel models. They do share a few differences, however. They too use a single power supply to provide a higher output voltage, stepped-up from 12V, to drive the speakers with more power than is possible with only 12V like factory systems.
Following this, they contain 4 independent audio amplifier sections which these days are normally designed in such a way that each channel pair can be bridged for additional power if desired. Some have features such as a bass boost control that may be used only for 2 of the 4. This varies from brand to brand and model to model, so its important to be sure before buying.
A 4 channel amplifier is basically the same as a 2 channel amplifier with 2 additional audio channels in a more compact design. Its important to note that some, however, do have special features available only on 2 of the 4. This 4 channel class A/B amp has quite a few transistors on the left-hand side to drive the outputs. Thats one reason its longer than a 2-channel amp alone.

The Complete Guide To Buying Amplifiers
Before you buy an amplifier, you need to make sure that its well-suited for your needs and also that its compatible with your existing car audio set up. Hence, there are a few factors to consider before you make a purchase.
In this guide, Im going to be breaking down the most important technical specs you should be looking at. These include class, power output, impedance, speaker sensitivity, and frequency response. If youre confused by these terms, theres nothing to worry about. Ill be explaining what they are and why theyre important.
Most amplifiers belong to one of four main classes, which are A, B, A/B and D. The main difference between them lies in how efficient their circuits are. In this context, efficiency indicates how much Alternating Current an amplifier is able to output while using up the least amount of Direct Current . Heres a simple overview of the differences in efficiency among different amplifier classes:
Class A amplifiers are the least efficient of all. This is because they contain simple circuits that cause the unit to conduct 100% of the time. As you might expect, not all of this electricity will be used by your speakers, leading to a lot of wastage. Hence, their efficiency is around 30%. This continuous conduction leads to a lot of heat being generated as well, so you could cause a Class A amplifier to overheat if you use it for prolonged periods of time.
What To Look For In A Car Amp
There are a number of basic features that although are very common in modern amplifiers you should always verify theyre present before purchasing, rather than assume.
I recommend an amplifier with built-in high and low-pass crossovers. The best ones are adjustable although thats not a big deal in everyday use. But it does make it easier to tailor the sound to your liking and its especially true when using the high-pass feature to block lower end bass from speakers that cant handle it in order to prevent distortion and get more clean high volume sound.
Ideally youll also have an amplifier with good terminals that are easy to connect power and speaker wire too but stay nice and tight after installation.

Tips For Buying And Using A 4
Once youve decided to upgrade your stereo system with an amplifier , then youve already committed to enhancing the listening experience in your car. Even if you already have an amp and sub installed in your vehicle, they may not be providing the pop that you want from your music, particularly if they dont have the wattage you desire.
If youre creating a custom sound system, there are some things you need to remember in order to set everything up properly. Its easy to make mistakes if you dont pay attention to the specs of the various components in the audio system.
- When selecting an amp, buy one that is more powerful than you need. Look at the RMS of the speakers and sub. Additional power will boost the depth of the music.
- Be careful not to overload your amp. Make sure it is compatible with the number of ohms that you will be wiring it up to.
- Pair the amp with aftermarket speakers because your factory speakers may not be compatible.
- Many people will be satisfied with an amplifier that provides just 50 watts per channel because it will deliver enough volume in most types of vehicles.
How Many Speakers Will You Be Powering
Amplifier outputs are separated into channels. Generally speaking, each channel can power one speaker. The average car has four channels: a front left, front right, rear left, and rear right.
Commonly amps will have either Some amps will have more, and some cover a range. For the most part, just count the number of speakers you will need to power and get that many channels.

An Amp Is Only One Part Of The Sound System
When you choose an amp, you will have to decide what your sound system will be in its final form, not what it is right now. Its easy to just drop a small amplifier into the factory system and get the speakers loud. Its a whole new world of parts and accessories if you want to start getting competitive.
A factory sound system is simple. The head unit is powered by the battery and is connected directly to the speakers.
When you start getting into custom sound systems, things can get a lot more complicated. Adding in an amplifier often means running all new electrical and speaker wires. As systems get advanced, they introduce the components most people dont know about like crossovers.
If you start pushing things to the extreme, you will be looking at a complete overhaul of the cars electrical system. Bigger alternators, extra batteries, and massive cables are things you will need to push the limits.
Class A/b Vs Class D Amplifiers
Technology has improved a lot in the last several years when it comes to car amplifiers. Although the traditional designs that have been around for decades, class A/B amps, still remain.
Whereas as traditional A/B amplifiers are based on a design in which driving transistors largely remain on during use and are only near 65% efficient, class D amplifiers are nearly 90% efficient and can be designed to fit into much smaller chassis.
A class D amp works by switching the transistors that create an audio waveform incredibly fast, saving energy and bringing heat levels down to an incredibly low level.
