    The Nobsound Lepy 168Plus Mini 2.1 Channel 80W+68W Hi-Fi Stereo USB/SD/Bluetooth/AUX/RCA Audio Digital Power Amplifier slots right in at second on our list and for good reason.

    Bass levels are good and the high-end is handled pretty well without sounding a bit hissy and tinny.

    ONEU Mini Amplifier Super Bass, Hi-Fi Subwoofer

    The ONEU Mini Amplifier Super Bass, Hi-Fi Subwoofer Stereo Amplifiers is one of the more reliable mini audio amps.

    If you’re a fan of booming low-ends, this device is perfect for you. It delivers 20W of power and offers treble and bass controls. One feature that we liked is that it has a super bass button which pumps out some serious bass.

    Audio quality is punchy and focuses more on the low-end with sufficient mids. The construction and build materials are of high quality and it’s lightweight and portable enough to carry anywhere.

    Volume levels are pretty loud too and there’s no hint of distortion even when cranked up all the way. If you love booming bass, definitely pick this mini amp up.

    The Good
    • Good bass levels
    • Sturdy build quality
    • Consistent volume levels

    It’s got smart features like a loudspeaker protection circuit that works to protect your speakers from sudden loud audio bursts. Build quality is also great which makes this the heftiest amp on the list.

    ELEGIANT Mini 20W 12V Hi-Fi Car Stereo Amplifier

    The ELEGIANT Mini 20W 12V Hi-Fi Car Stereo Amplifier Power is one of the smallest speaker amplifier we reviewed and tested. Despite its size, it’s a capable little device that offers 20W of power on two channels and delivers rich sound.

    There’s a slight bit of hiss and distortion when you hit peak volume levels but it’s not too noticeable.

    It’s very compact and would work perfectly with your car stereo or if you want to fill up a small room with good sound.

    Design and build quality is about average especially when it comes to the dials.

    You can alter your music with the treble and bass knobs and depending on the music, cranking up the bass levels may sound muddy.

    It does the job pretty well and although it won’t be an audiophile’s first choice, you’ll be satisfied with its performance if you’re looking to boost your sound quality.

    The Good
    • 20W of power on two channels
    • Rich sound on mid-volume levels
    The Bad
    • Subpar build quality
    • Slight hiss on high volume levels

    MENGGOOD Mini Hi-Fi Bluetooth Stereo Digital Power

    The MENGGOOD Mini Hi-Fi Bluetooth Stereo Digital Power Amplifier has a lot of features going for it that make it a capable amplifier that’s sadly let down due to its inconsistency and build quality.

    It’s got an FM radio onboard so you can listen to your favorite local radio stations and the signal reception is great.

    There’s a whole host of buttons on the front of the amp to control your music like pause/play, previous and next.

    A remote control is also included and allows you to operate it wirelessly. An SD card and USB slot is also present which makes it versatile in terms of music playback.

    Sound quality is good and there’s enough clarity when you listen to your music. It’s when the volume levels go up that the audio quality dips down.

    The materials used also feel dubious and tacky. For its price, you’re better off selecting a great sounding amp like the Nobsound Lepy 168Plus Mini 2.1 Channel 80W+68W Hi-Fi Stereo USB/SD/Bluetooth/AUX/RCA Audio Digital Power Amplifier.

    The Good
    • FM radio onboard
    • Remote included
    • SD card slot for music playback
    The Bad
    • Inconsistent audio reproduction
    • Lackluster build quality

Frequently asked questions

What is a mini stereo amplifier?

A mini stereo amplifier is a compact, portable device that takes a weak signal input and produces a more powerful signal as an output.

Mini stereo amplifiers are used to boost and improve audio signals from your speakers and headphones.

Why should I consider using an amplifier?

There are plenty of reason why you should consider using a mini stereo amplifier especially if you’re looking to boost your speakers’ overall sound quality.

Here are some reasons as to why you should pick up a mini stereo amp.

  • Better audio quality. OEM and built-in amplifiers are generally okay when it comes to driving the factory speakers they came with, but aftermarket amps will open up a whole new world of sound output. You’ll be able to hear the difference once you set up an amplifier and connect your speakers.
  • Portable and compact. One advantage of using mini stereo amps is that you can take it anywhere and use it wherever you like be it your car, bedroom, kitchen, or even your living room floors.
  • More control over your audio output. Using a mini stereo amp will allow you to have more control over the sound of your speakers. Not only will you be able to add more volume to your speakers, but you’ll also have more control and better quality audio reproduction to fine-tune your music tastes just the way you like it by adjusting treble, bass, and crosstalk dials.

What should I look for when choosing a mini stereo amplifier?

Before you pick up your brand new mini stereo amp, here are a few important factors to look out for to make sure you get the correct purchase.

Consider your needs and take these factors into consideration before buying.

  • Power output. The power output of your amplifier will give you an idea of how loud your speakers can get. If you use big speakers, you’ll need plenty of watts to pump out some serious sound but for mini stereo amps, you’ll be okay with 20-80 watts.
  • Build quality. A small speaker amp should be constructed of lightweight, durable materials so you can take it anywhere without having to worry about it breaking apart.
  • Input/connections. Consider the input/connections of a mini speaker before purchasing. If you’re looking to plug in your laptops and pc, make sure it has a USB port. A 3.5 mm works well for your phones and some mini stereo speakers even have bluetooth for wireless connectivity.

What’s the best mini stereo amplifier? Why is it the best?
