Best Bluetooth Car Amplifiers 2023

The key distinction between a Bluetooth amplifier and other car amplifiers is that all of your Bluetooth-enabled gadgets may stream music directly into it. Simply said, a Bluetooth car amp eliminates the need to purchase a head unit, saving you money in the process.

Car amplifiers are not an exception to the rule that anything having Bluetooth in it will be more practical. Instead of connecting to your stereo, they allow you to stream music directly from a Bluetooth-enabled device. As a result, they enable wireless streaming even if you lack a Bluetooth-compatible radio or head unit.

Kenwood KAC-M1824BT

The Kenwood KAC-M1824BT 4-channel amp is our best value choice because to its cutting-edge technology, wide range of uses, and affordable pricing. The 4-channel Bluetooth amplifier from Kenwood, the KAC-M1824BT, can handle the complete audio spectrum, from lower treble to upper bass. As a result, both ordinary speakers and subwoofers can be used with it. Although 45 Watts may not seem like much, they are actually quite sufficient, especially if you have a speaker that is already quite sensitive (90 dB or more). You can bridge the amplifier into a 2-channel mode to increase the RMS in each channel to 90 watts if you need a little extra power to connect a pair of subs.

It can be placed on your motorcycle, ATV, boat, and other vehicles besides only your automobile. This is made feasible by the primary PCB of the amplifier having a conformal coating that protects it from external moisture and salt from marine conditions. Utilizing Bluetooth allows you to control your music wirelessly, which is far more enjoyable than using RAC input wires, which can occasionally fail you. Because of its small size and ability to withstand water, it is ideal for use in places where amplifiers have not yet been installed due to space constraints and the risk of environmental damage.

An IPX-5 certified remote is included. The remote can function even when submerged in water thanks to its IPX-5 certification. As a result, it may be used to run a boat, an ATV, and a motorcycle. You can toggle between Bluetooth and the RCA input as your music source using the IPX remote, which also handles Bluetooth on and off operations.

The amplifier’s power wire is connected directly to the head unit’s power line if an aftermarket unit without a preamp output is utilised. This is so that your amplifier will turn on when a signal from the unit input is detected because this amplifier has a signal-sensing turn-on feature. This function does away with the necessity for a turn-on lead to be installed on the amplifier’s power control wire. This is one of the Best Bluetooth Car Amplifiers in 2023.

S.M.S.L AD18 HiFi Audio Stereo Amplifier with Bluetooth 4.2

The SMSL AD18 Class D amplifier was created exclusively for use with subwoofers because of its frequency response, which spans 20 Hz to 250 Hz. The SMSL AD18’s two channels each have an RMS rating of 80 watts. This power output ought to be adequate if you’re not the kind of person who regularly cranks up the subwoofers to ear-splitting decibels. It was good to see a coloured display as not many amplifiers had one. I didn’t have to bend in and take my eyes off the road for more time because of this 1.44-inch screen’s ease of use in monitoring the output level while I was driving.

The support for Apt X in Bluetooth 4.2 is one of my favourite features. A way for sending high-quality audio files is called Apt X. Due to its limited bandwidth, Bluetooth must first compress larger audio files before sending them. Apt X is able to lessen the standard level of compression, which improves the music’s ability to keep all of its subtleties and features.

You may play your music through the SMSL AD18 in addition to Bluetooth. A headphone connector and a micro USB input are also included. Since I save the majority of my “on-the-road” playlists on a USB stick rather on my phone, I found the former to be rather beneficial. Also occasionally helpful is the headphone jack, especially when I wish to listen to a podcast or a contemplative CD in privacy. Make sure to place the amp in an accessible location if you intend to use the headphone jack.

Since the SMSL AD18 only weights 3.5 pounds, installation is hardly a trouble. Additionally, you’ll have a variety of placement options while setting it up because to its 6.8 inch width.

Complete Guide to Bluetooth Car Amplifiers – Buying Guide

Make sure an amplifier is suitable for your needs and compatible with your existing automobile audio system before you purchase it. As a result, there are a few things to think about before you buy.

I’m going to break out the key technical specifications you need to pay attention to in this article. These include speaker sensitivity, class, power output, impedance, and frequency response. There’s nothing to worry about if these terms are unclear to you. I’ll describe them and why they are significant.

Class

A, B, A/B, and D are the four main classes in which the majority of amplifiers fall. The effectiveness of their circuits is the primary distinction between them. Efficiency in this context refers to how much Alternating Current (AC) an amplifier can produce while consuming the least Direct Current (DC). Here is a brief summary of how several amplifier classes differ in efficiency:

A class

The least effective amplifiers are Class A amplifiers. This is so that the unit will always operate because they have straightforward circuits in them. The majority of this electricity will be wasted because, as you may anticipate, your speakers won’t consume it all. As a result, their effectiveness is about 30%. You might cause a Class A amplifier to overheat if you use it for extended periods of time because continuous conduction generates a lot of heat.

The finest signal purity is provided by Class A amplifiers, which is their main advantage.

B Class

The architecture of class B circuits makes them only conduct electricity roughly half the time. This results in less wasted electricity and a considerably greater efficiency (70%) overall. Class B amplifiers’ primary flaw is that they exhibit some degree of signal distortion.

Type A/B

Class A/B amplifiers combine the circuits of Class A and Class B to create a hybrid of the two. As a result, you obtain Class A power efficiency with Class B signal purity. Biasing diodes, which are used in the Class B chain, are intended to assist reduce the distortion that these kinds of circuits frequently produce.

D class

Class D amplifiers have the highest efficiency (90–95%) because they are truly off when they are turned off. This implies that the output transistors do not store any electricity at all when the switch is turned off. There is therefore none left to be transformed into heat energy.

Power Output

By sending more power to speakers and subwoofers, amplifiers boost their output volume. Therefore, you would require a rather powerful amplifier if you were to constantly blast your music. The speakers must, however, be capable of handling the amplifier’s output power, and this is the crucial aspect. They can overheat and potentially have their internals fried if the power is applied above their limit for handling it.

RMS and Peak Power are the two metrics used to gauge a speaker’s ability to handle power. While the latter specifies the absolute upper limit for what it can manage, the former indicates how much power (measured in watts) a speaker can safely handle continuously.

The RMS and Peak Power standards for amplifiers are similar, however they deal with power output rather than handling. You can typically find the RMS per channel in the product information sections. Otherwise, you run the danger of damaging your speaker, therefore be sure that its RMS is at least as high as this amount.

Speaker Sensitivity

Do your speakers require a lot of electricity to reach their full volume? The sensitivity rating of a speaker will specifically tell you that. A speaker’s speaker sensitivity describes how loud it will get (in dB) with just one watt of electricity. For instance, if a speaker’s sensitivity is 85 dB, you would know that one watt will drive it to a moderate volume. You can increase the level by 3dB for every additional watt you provide.

Less power is required for a speaker to reach a given volume the higher its sensitivity.

Impedance

Impedance measures how many ohms of internal resistance your amplifier has. The harder the amplifier has to work to output a specific quantity of current, the higher the impedance. A low impedance is therefore less demanding on an amplifier, however it isn’t always optimum. An amplifier can produce more current than a speaker can handle if the impedance of the amplifier is too low.

The majority of amplifiers have an impedance of 4 ohms by default, but you can change this to a 2-ohm setting if you need additional power. The RMS of the amplifier at each ohm level is typically listed in the product information sections, which is rather useful.

Frequency Response

While some amplifiers can only be used with subwoofers, others can be used with both types of speakers. The frequency response of an amplifier will reveal the kind of amplifier it is. It is essentially the frequency range that an amplifier is capable of handling. A subwoofer unit is limited to the bass region (20 Hz to 250 Hz), but a full-range amplifier can handle all signals in the human auditory range (20 Hz to 20,000 Hz).

Consequently, be careful to always pay attention to the frequency response to avoid unintentionally purchasing the incorrect amplifier for your setup.

Channels

Depending on how many speakers you already have in place and whether you want to add any more in the future, you’ll need a certain number of channels in your amplifier. 5-channel amplifiers have a wide range of applications. They offer a separate subwoofer output in addition to 4 conventional channels. As a result, you may also connect a subwoofer and up to four speakers.

The Capacity For Bridging

In essence, bridging an amplifier is combining the power output of several channels into one. Typically, this is done to increase the amplifier’s compatibility with a subwoofer because they require a lot more power than standard speakers. To connect to two subs, for instance, you can bridge a 4-channel amplifier into a 2-channel mode.

Frequently Asked Questions

What is a Bluetooth Car Amplifier?

In principle, a Bluetooth car amplifier can decode and transmit a Bluetooth (wireless) signal from an external device to speakers. The external device is typically a smartphone made by Apple or Android, or a media player like an iPod or Walkman.

The majority of Bluetooth car amplifiers come with an external control pad. This extra device is intended to be positioned up front, within the driver’s reach. The amplifier can be mounted and concealed in conventional installation positions including inside a dashboard, in the trunk, or under a seat. The power on/off, volume up/down, seek forward/reverse, and source selection buttons on the controller are standard.

Why do I Need a Bluetooth Car Amplifier?

You might be asking what the use cases are for Bluetooth car amplifiers. I’ll give you a few instances of issues that Bluetooth car amplifiers can resolve and the locations where they work best.

Standard Car: There are a few situations where Bluetooth car amplifiers are appropriate for a standard daily automobile. First off, many vehicles were never built with factory-installed Bluetooth audio connectivity. You may acquire the connectivity you require and improved sound quality with a Bluetooth vehicle amplifier rather than going through the effort and expense of upgrading the system. One stone kills two birds. Second, for a complicated vehicle, a Bluetooth car amplifier can be the answer. When installing an aftermarket sound system in some automobiles, it can be very challenging. You may effectively “bypass” the inbuilt stereo entirely by using a Bluetooth amplifier to control your aftermarket sound system. This is a surefire way to achieve excellent sound without having to deal with the difficulties of integrating with a high-end source unit and OEM amplifier.

Hot Rods & Classic Cars: Let’s start with vintage automobiles first. Over time, as the value of historic cars has increased, so has the need to preserve their originality. The owners of these cars take extraordinary care to keep the interiors, wheels, and body panels in the same condition as when the car rolled off the manufacturing line 40 to 100 years ago. These customers still want to drive their cars and listen to music, though. They may stream music from their mobile devices without affecting the dashboard or factory radio thanks to a hidden Bluetooth amplifier. Let’s talk about hot rods next. Hot rods are modified and custom-built automobiles that never included car stereos or had room for them. Once more, the driver can stream directly into it by concealing a small Bluetooth amplifier, saving time mounting and wiring a car audio.
