10 Best Budget Mono Car Amplifier [Reviewed in 2023]

Are you tired of your car’s speakers sounding like they’re coming from a tin can? Or, do you want to get the best sound out of your car stereo system? If so, you need a mono car amplifier to get the party started. 

best budget mono car amplifier

A mono car amplifier is an audio power amplifier that provides the necessary amount of power to drive one loudspeaker. This amplifier can power speakers in automobiles, boats, and other vehicles.

They are best suited for low-powered applications where high-quality sound reproduction is desired. Most have built-in protection circuitry to prevent damage if they are overloaded or shorted out by accident. 

Mono amplifiers are designed specifically for use with subwoofers. They produce more bass than conventional stereo amplifiers due to having only one channel output stage rather than two.

With so many different models and brands available, which one should you choose? Check out our detailed review of the 10 best mono car amplifiers to find the perfect one for you.

Best Budget Mono Car Amplifier Buying Guide

Car Audio amplifiers are one of the most important components in your car audio system. They take the low-level signal from your stereo and boost it to power speakers, subwoofers, tweeters, etc.

However, not all of them do their job effectively. So, below are five factors that need consideration when buying an amplifier for your car. 

Class of Mono car Amplifier:

There are four classes of car amplifiers: A, B, D, and A/B. Class A amplifiers are the best sounding, but the most inefficient, requiring more power from your car’s battery and alternator. They also run hotter than the other three classes.

Class B amps are less efficient but still sound good and run cooler than Class A amps. Class D amps are the most efficient and generate very little heat, making them ideal for use in cars.

Class A/B amps combine the best features of A and B into one, so they sound great with more efficiency and run cooler with low distortion. Most budget mono car amplifiers are class A/B or D. 


This is the most important specification of any amplifier. The power rating tells you how much power the amp can put out into your speakers. You want an amp rated for more power than your speakers need. Otherwise, they will not play music to their full potential.

For a budget mono car amplifier, aim for around 400 – 1500 watts RMS per channel. This should provide plenty of power for most factory or aftermarket speakers. Keep in mind that the peak power rating of an amplifier is not as important as the RMS rating.

This is because the RMS (Root Mean Square) rating tells you how much power it can deliver continuously. 

Quality of Sound:

Many factors go into the sound quality of a car stereo system. Amplifiers can have a big impact on this as well because they affect the signal going to your speakers and subwoofers before it is turned into actual sounds you hear while driving.

You want an amplifier with low distortion so you’ll experience clean, crisp audio without any annoying buzzes or rattles! 

Choose one with good internal components such as good capacitors and heavy-duty aluminum heatsinks for cooling purposes.

If possible, buy an amplifier from a reputable company like JBL, Kicker, Alpine, etc., rather than something cheap made in China off eBay or Amazon just to save yourself some money since those tend to create more problems down the road due to poor manufacturing standards.

Mosfet Power Supply:

This is a power supply type found in better-quality amplifiers. It uses Field Effect Transistors (FETs) to switch the amplifier’s power supply on and off, which results in less distortion, higher efficiency, and cooler operation. 

A budget mono car amplifier without a Mosfet power supply will likely still work fine, but it won’t sound or run as good as one with this feature. When shopping for an amp, look for the term “Mosfet” somewhere in the specs or features list. If it’s not there, then chances are the amp doesn’t have one and isn’t of very high quality.

Remote Bass Control:

This feature lets you control the bass level of your subwoofers from inside the car. This is very useful because it allows easy adjustments to match what’s playing on your stereo at different times during driving.

This ensures that you’re always hearing optimal sound quality without having to manually adjust things every time. Look for this in a good budget mono car amplifier!

Final Thoughts

A car amplifier is an inexpensive investment in driving your music even louder than ever before without sacrificing clarity or fidelity.

If you like your music turned up loud while driving, our list of mono car amplifiers are a great way to get more bass and volume for your sound system. 

Finally, these amplifiers have been carefully chosen based on their performance, build quality, customer service comments from individuals who have purchased them before you. So, what’s holding you back? Find one right now that suits your needs!
