Have you ever imagined driving your car and playing your favorite tunes, in a crispy, loud, and clear devoid of noise or distortion?
Well, that is one sensation you relish in, from a car amplifier.
A car amplifier takes signals from the stereo and uses an independent power source to change it into a more powerful signal for the speakers.
They are one of the modern devices used for powering speaker systems, as well as replacing factory amplifiers, and adding subwoofers.
The amplifier performs the key role of boosting and increasing the signal power or strength of an appliance. It goes further by boosting a very small electrical audio signal to a higher voltage capable of running loudspeakers.
Interestingly, a car amplifier uses a unique kind of internal power supply which helps to supply the internal amplifier circuitry with a higher power. The amp takes a conditioned audio-signal, boosts it, and proceeds to deliver it to the speaker terminals.
Undoubtedly, the car amplifier is a must-have for every car owner. In addition, the car amplifier takes a weak signal and amplifies it, providing power and volume to your car tunes.
The car amplifier is usually ‘buried’ in the car, hence, you rarely see it. They typically improve the low-level audio signal generated by the head unit, hence, the amplifier is powerful enough to move the cones of the speakers in the system to create sounds.
The more powerful a car amplifier is, the clearer the sound emanating from the speakers. It is crucial to match up your stereo and speakers with the right amplifiers.
There are two major power ratings that exist in a car amplifier namely; the Root Mean Square(RMS) power and the Peak power.
The RMS number on your amplifier should match with the ratings on your speaker if not, it can result to an under-powering or an invariable over-powering of the speakers.
When over-powered, they have the potential of overheating or becoming totally damaged, and you do not want such happening.
It is also imperative to get a professional to help install your car amplifier since they know the intricacies of such.
Car amplifiers can draw a lot of electrical current of up to 50 amperes, particularly when close to maximum power. However, during low-volume usage, they draw a few amperes.
Car amplifiers are usually linked by a fuse to the vehicle’s battery for positive wire, while the ground or negative cable is linked to a metal connection on the body.
This is due to the fact that the car’s original wire cannot take the level of current an amplifier needs, under intense use.
Features of a Car Amplifier.
There are certain features the car amplifier possesses, particularly in their designs and these include:
1. A DC-DC (Direct Current) high switching power supply.
2. Noise prevention (“ground loop”) circuitry.
3. Speaker crossover circuitry.
4. Bridging circuitry.
5. Speaker-level input.
The speaker-level input feature is optional as it is a product-specific option.
1) Direct High Power: There are two major sections in a vehicle amplifier- the amplifier & output section, and the input stages comprising many minute circuits that provide crossover functions, gain control and block ground loop noise.
The input stages(usually grouped together) allow the amplifier to connect to stereos with no RCA jacks, prevents terrible “ground loop” interference from getting amplified, provides low-pass and high-pass crossover functions.
They consist of a kind of electronic component called an operational amplifier (op-amp) which are little amp circuits built in a small chip used for different designs.
2) Noise Prevention: Ground loop noise, also known as “alternator whine” can be annoying and troubling while listening to music in your car. Hence, the feature of noise prevention of the car amplifier is a pertinent one.
The ground loop noise is an electrical noise that comes off as a terrible whine that increases or decreases with the engine speed of a vehicle.
This noise can be due to currents that flow in a car’s body and the connections of the audio component. The car amplifier contains circuitry to eliminate any form of ground loop noise in its installation.
3) Crossovers: Crossovers are nice features of today’s car amplifier. An example is the electronic crossover which offers a cheap, space-saving way of sending only bass or upper-range sounds to a speaker.
When subwoofers are driven for example, the low-pass crossover in an amplifier blocks everything save bass. In addition, you can as well block low-end bass from small speakers with the help of a high-pass feature.
4) Speaker Level Inputs: The speaker level input is usually connected to the wiring which is plugged to a connector on the amplifier, and then the high-level signals are converted to low-level signals.
Speaker level, also known as high-level inputs take the higher voltage speaker level signal directly from speaker wiring and reduces it to a smaller level that the amplifier can use.
How A Car Amplifier Works.
A car amplifier usually comes with a “remote” wire, that connects to a dedicated wire on your stereo, which turns off the amplifier when not in use.
The remote wire can also be connected to an ignition wire that turns off when the accessory position of the ignition switch is turned off.
Car amplifiers use a special kind of internal power supply which supplies the internal amplifier circuitry with a higher power.
It is then taken to a conditioned audio signal, usually provided by the stereo, and delivers it to the speaker terminals.
In installing the car amp, large capacity power cables are linked to the power terminals and are fastened with the aid of screws.
Upon installation, the car sound system is test run and the amplifier’s crossovers and gain control are adjusted accordingly. It is pertinent to note that for the car amplifier to function properly, they must be fixed with sufficient sizes and types of wire.
Importance of a Car Amplifier.
There are numerous benefits accrued to using a car amplifier, and they include;
1. The car amplifier amplifies sounds from the speaker.
2. It can power a car’s stereo-system with excellent power and sound.
3. The power provided by a car amplifier supercedes that of an average car stereo.
4. Sounds emitted from a car amplifier are clearer, smoother and crispier. The car amplifier offers better sounds, especially when playing bass-heavy tracks.
5. Car amplifiers with built-in crossovers help prevent distortions and allows you to play speakers at higher volumes with enhanced clarity.
6. Car amplifiers boost a small signal to a larger signal than can drive speakers.
7. The 4-channel amplifiers are bridgeable, flexible, hence, can be used for up to four speakers, which is a development on the 2-channel amplifier which uses only two speakers.
8. Car amplifiers are used to fix several car audio issues and increase sound.
9. Car amplifiers provide higher power, which the stereo cannot provide.
Video: What is the best car amplifier.
Car amps have many advantages and are needed in most cases. Car radios, in general, can produce about fifteen to eighteen watts per channel.
When trying to move speakers that require more power, the stereo sound becomes contorted and terrifying. Driving speakers and with a higher power is generally not possible with car radios alone.
This is where the car amp comes in. Your car amplifiers offer better sound, most especially for heavy bass music. Some special cases may arise where they are the only way to increase the sound inside a car:
– Factory stereo without low-frequency sound
– Amplifiers mounted by a dead or weak factory
– Strong desire, clear voice while enjoying high-quality music
– Car owners who need high volumes
– Ships and other external vehicle owners (external vehicles require extra power to produce better audio)
Just as stated earlier, many features, such as the built-in crossover, prevent distortion while allowing you to reproduce loudspeakers with higher volumes more clearly. Factory systems usually can’t, and the audio will collapse earlier as it grows.
Installing an optional amplifier fixes this issue and gives you good control over the audio system. In addition, the system can be easily increased to add missing bass subwoofers by adding a second amp or using two channels with a four-channel amplifier to turn it on.
The 4-channel amplifier is almost identical to the two-channel model. However, they have some differences and are more useful in most cases. 4-channel amps differ primarily in design. they come with 2 additional channels to add more speakers.
Using a four-channel amplifier instead of one channel amplifier offers several advantages:
- You can control the front and back speakers
- Drive the full-range front speakers and use channels three and four for the subwoofer
- Usually more compressed than two separate stereo amplifiers.
Most four-channel amplifiers are also mobile now, so they could be used very flexibly. This means you can not only use it for two or more car speakers: It is also possible to use 2, 3, or even 4 channels, depending on the connection function used.
We hope you have learned what you need to have knowledge of automatic amps. Here are important things to consider:
- Car amplifiers amplify the small signal into a signal that is larger than what the loudspeaker can control.
- Used to fix many audio problems automatically and improve audio
- Car radio cannot produce a high performance as an amplifier

If your sound begins to snap or misshape at high volume, turn it down! If you need it stronger, you’re going to require more force and turning your amp’s handle won’t get that going.
Check the connections. There’s a great deal of current moving through those force links, and likely a ton of vibration in your vehicle if you have a major framework. Grounds ought to be checked occasionally to ensure they are still tight and not beginning to erode.
The equivalent goes for your battery terminals and any force dissemination blocks in the framework. You must keep that present streaming on the off chance that you need to prop the music up.
Secure your speakers. Don’t let anything hit your subs. You will notice they take a greater portion of your trunk and letting your goods and clothing skip off moving subwoofers is awful for them.
That bowling ball moving around back there can do some genuine harm. Put a few grilles on those speakers or keep the storage compartment clean. It’s just as simple as that. Most vehicle sound gear today is worked to withstand the earth inside a vehicle and the temperature limits that go with it.
