Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
Amplifier Key Features
Amplifiers can offer a diverse array of features. If you select more than one feature, then you will view amplifiers that have ALL features selected. These include speaker-level inputs that facilitate seamless integration with factory audio systems, Bluetooth connectivity suitable for ATV/UTV or Classic vehicle setups, built-in DSPs that provide enhanced control over your audio signal, and a host of other functionalities to explore.
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.
Total Peak Power Output
The total peak power output is measured as the wattage per channel multiplied by the number of channels, and is calculated at the lowest level of operating impedance.

It is measured during a brief musical burst, such as a sudden drum accent. Some manufacturers display peak power ratings on the face of their products to increase the appeal.

The RMS power rating is more accurate, and we recommend using it for product comparison.
Series
Many brands group their products into series or lines of products to help customers know the level of quality (good, better, best for example). You can filter by series and the brand using our guided browsing.
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
Remote bass/level controller
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Amp Bluetooth Connectivity
This feature will tell you if the amplifier has the capability to connect to a Bluetooth device.

    FAQ Frequently asked questions in Mini Car Amps

    Mini Amps Frequently Asked Questions (FAQ)
    Mini amps, also known as micro or compact amplifiers, are smaller-sized amplifiers designed to deliver enhanced audio performance in a compact form factor. Despite their small size, mini amps can still pack a punch and significantly improve your car audio system's sound quality. They are ideal for vehicles with limited space or for those seeking a discreet installation. Mini amps are available in various configurations, including 2-channel and 4-channel options, providing flexibility in powering different speakers or subwoofers. While traditional amplifiers may offer more power and features, mini amps strike a balance between size and performance, making them suitable for both OEM and aftermarket audio systems.
    Yes, mini amps are capable of powering both speakers and subwoofers in your car audio system, but the power output will be more limited compared to larger amplifiers. The wattage of mini amps typically ranges from around 50 to 200 watts per channel. For most standard car audio setups, a well-chosen mini amp can provide ample power to drive your speakers, resulting in improved sound clarity and dynamics. Additionally, mini amps with bridgeable configurations can power a subwoofer, providing the low-frequency bass response you desire. However, for enthusiasts seeking extremely high-power setups or multiple subwoofers, larger amplifiers might be more suitable. Sonic Electronix offers a wide range of mini amps with varying power outputs, so you can find one that best fits your specific car audio needs.
    Mini amps are generally designed for easy installation and are suitable for DIY enthusiasts. They come with detailed instructions, wiring diagrams, and mounting hardware, making the installation process straightforward. Most mini amps use standard wiring connections, such as RCA inputs and speaker wire outputs, making them compatible with various car audio systems. However, while the installation is relatively simple, it does require a basic understanding of car audio wiring and electrical connections. If you're not comfortable working with car audio systems, it's best to seek professional installation to ensure a seamless and error-free setup. Sonic Electronix's knowledgeable staff can provide installation advice and guidance, helping you make the most of your mini amp and achieve the best audio performance.
    Like all amplifiers, mini amps generate heat during operation. While they produce less heat than larger amps due to their lower power output, it's still essential to consider ventilation during installation. Mounting the mini amp in a well-ventilated area with sufficient air circulation helps dissipate the heat, preventing overheating and potential damage to the amp. Avoid installing the mini amp in enclosed spaces or areas exposed to direct sunlight, as this can lead to temperature build-up. Some mini amps come with built-in cooling features like heat sinks or fans, which aid in heat dissipation. Additionally, ensuring that the mini amp is securely mounted will prevent vibrations that may affect its performance. Following proper installation guidelines will optimize your mini amp's efficiency and lifespan.
    Mini amps are compatible with both factory car stereos and aftermarket head units. They typically feature speaker-level inputs, allowing you to connect them directly to your factory stereo's speaker wires. This feature is essential as most factory stereos do not have RCA preamp outputs required for traditional amplifier connections. By using speaker-level inputs, you can easily integrate a mini amp into your factory audio system, enhancing its performance without replacing the head unit. However, if you prefer additional audio customization features or advanced connectivity options, upgrading to an aftermarket head unit can be beneficial. Aftermarket head units often provide RCA outputs, enabling a cleaner and noise-free connection to the mini amp. Whether you choose to use your factory stereo or upgrade to an aftermarket head unit, Sonic Electronix offers mini amps that cater to various installation requirements.

    If you're searching for the best quality mini amps, you've come to the right place. Our extensive collection features only the finest mini amplifiers to enhance your car audio experience. Whether you're looking for compact power or space-saving solutions, our selection of mini amps offers the perfect balance of performance and convenience.

    Mini amps, also known as micro amplifiers or compact amplifiers, are designed to deliver impressive audio performance in a small and space-efficient package. Don't be fooled by their size; these tiny powerhouses pack a punch! One of the main advantages of having a mini amp is its versatility. These compact amplifiers can fit into tight spaces, making them ideal for installation in areas where larger amplifiers may not be practical.

    Despite their small size, mini amps are capable of providing a significant boost in audio power. They can enhance the clarity, depth, and overall quality of your car audio system, delivering a dynamic and immersive listening experience. Whether you're looking to power your speakers or add some extra oomph to your subwoofer, mini amps are up to the task.

    Another advantage of mini amps is their energy efficiency. These amplifiers are designed to consume less power while delivering outstanding audio performance. As a result, they produce less heat and are less taxing on your vehicle's electrical system, which can be beneficial for both your car and your wallet.

    Beyond their performance, mini amps are easy to install and integrate into your car audio setup. Their compact size makes them convenient for DIY installations, and many models come with user-friendly features, making the installation process hassle-free.
