Car stereos have inbuilt amplifiers, and their function is to boost the sound signals from various audio sources such as CD players and radios - for powering the speakers. The factory-mounted amplifiers rate high in quality, but there are times when an external amplifier unit is needed.
This is because dashboards have limited space due to which only small-sized units are mounted; they offer around 10 watts for every station. Stereo systems are upgraded by installing car amplifiers and subwoofers for producing clearer and louder sounds.
We have seen that the function of car amplifier is to heighten the strength of the sound signals from audio connections by powering the speakers. If you wish to purchase the systems, you should visit electronic stores or audio centers.
You can also buy them online or in the marketplaces. They are available in various configurations: mono-channel varieties are sufficient for subwoofers or single speakers; the five-channel range caters to the advanced models.
Amplifiers are a technological gear, and they can be cumbersome to sort through its various specifications. Additionally, mounting an external amp is not an easy task; incorrect wiring can cause damage to the other car parts or result in overloading the current power units.
However, they serve a variety of purposes, and are discussed in the following aspects.
Old car stereos may not have advanced features as the modern models. In such cases, mounting an amplifier with signal processors and equalizers would off-set the need for fixing a new one. It can prove to be a cost-saving exercise.
2. Increase Volume
Blaring engines, loud air conditioning sounds, and honking traffic are factors that could result in the audio not being heard effectively. Here, the installation of a car amplifier would be helpful to amplify the stereo volumes.
3. Enhancing Sound Output
Setting-up an amplifier is beneficial for improving the sound emitted by your car’s music system. These kinds of equipment use many output channels with a number of watts differing according to the choice of brand. If there is any interference from electrical parts, it could result in distortion and unnecessary sounds; external amps are effective for overcoming such problems. Moreover, for enhancing the quality of sound produced from the stereos, the bass should be increased; the amps are also useful for these purposes.
You must also try to look for a high-quality amp because a low-quality one can reduce the potential of the other related components. The ones containing a low deviation and broad frequency spectrum would be advisable to procure. The distortion of the amps is also listed, the lower this figure is, the more superior is its quality.
You are also recommended to approach reputed dealers for getting the best bargain; they supply the best quality electrical-based components that contribute towards improving the sound output.
You may also find it interesting to learn that amplifiers are classified according to the number of channels that can be powered by them. The one-channel ones are needed when adding a subwoofer or for powering one speaker. You can choose two-channel or four-channel varieties to power two speakers and four speakers respectively.
Here, it becomes necessary to know the number of channels needed, before making your choice. For example, the requirement of a system having four speakers along with a subwoofer would be a 5-channel amp or higher.
Availing the option of multichannel amplifiers provides more flexibility. An amp with numerous channels can pave the way for adding upgrades and additional accessories. Some car amplifiers are also designed so that they can combine different channels for producing an impactful sound; this is similar to the way subwoofers function.
Increasing the level of sound quality requires the use of the additional power. If you are keen on saving energy resources, fitting a car amplifier is a suitable option because they are energy-efficient. It is advisable to opt for the best car amplifier for maximum benefit.
Amps are classified into various categories; the higher the class, the greater the efficiency. Additionally, a well-fitted amplifier system will be able to keep the sound concentrated within the car interiors and prevent the noise from being heard outside the vehicle.
The power output of an amplifier is measured in watts. In some amps, the information about this measurement is provided on a per channel basis, and others give the total of all. The power output of the amp should match with the requirements of the speaker for producing sounds without distortion or other disturbances. Amps can produce power ranging from lower than 250 watts to several thousand; nonetheless, 500 watts is sufficient for most speakers.
RMS or root measure the uninterrupted power generated by the amplifiers or its total power output or the amount that the speakers require mean squares. Sometimes, two channels are combined for powering large-sized speakers or subwoofers.
The bridging of 2 channels of 150 watts is adequate for providing power to a 300-watt subwoofer. It is important to learn about the RMS, which is the power rating of the amp to gain knowledge about its ability to provide power on a continual basis.
6. Powering Upgraded Speakers
The factory-mounted amps can power the car speakers, but a significant number of patrons avail to upgrade their speakers. The after-sale speaker systems produce louder noises than the ones in the display; furthermore, they require additional power and a greater amp.
Factory-installed systems are upgraded by adding a subwoofer for bringing about an increase in bass output and more clarity at lower frequencies. The installation of a subwoofer requires an external amplifier unit to meet their power needs, which are higher than the amount that standard amps can supply.
You must take steps to choose the ideal external car amplifier, for enhancing the entire music-listening experience, when cruising through the busy roads. Whether you plan to add subwoofers or upgrade the speakers, these resources can supply the required power output for producing greater sound clarity without any distortion.
You may need to conduct research for making the right choice, but the effort is surely worth the rewards that are enjoyed. It is also important for patrons to know the wattage that is needed; additionally, they must also consider aspects such as the filters.
