Best Amplifiers For Car Audio in 2022 | Reviews and Buying Guide

best amplifiers for car audio

Best amplifiers for car audio in 2022. Vehicle audio system audio amplifiers are essential to help your vehicle perform on the road. Specific performance criteria must be met to meet the needs of all other parts of the audio system.

With so many differences from system to system, it makes sense that the market would be flooded with manufacturers making their own car amps.

Whether you’re starting from scratch or upgrading; or looking for a speaker or kicker subwoofer with large power components, choosing the right amplifier is key to your success.

Of course, the most important are the specifications. However, knowing a car amplifier from a reputable brand will certainly help you choose the right amplifier for your vehicle.

While clearly subjective and prone to bias, I’ve done my best to list these brands based on the following metrics (in no particular order).

Alpine S-A60M S-Series Class D Mono Amplifier

alpine s-a60m s-series

The massive bass performance of Alpine’s small package makes it a little easier to get good bass in your vehicle, especially if you drive a small car.

The S-Series S-A60M mono subwoofer amplifier can deliver up to 600 watts RMS to your sub and guarantees powerful bass in your drive.

And Alpine makes this amp so small, it’s less than 8 inches by 8 inches and just over 2 inches tall-it fits almost anywhere.

Technology that keeps you in the air Enhanced Shutdown Performance technology slightly lowers the output power when the amp threatens to overheat from being pushed to the limit for too long.

Instead of turning it off completely, it keeps playing your music until it’s cooled enough to start operating at full power again.

Handy Features An adjustable low-pass filter and bass boost lets you control the frequencies reaching your kicker subwoofer.

This amp features preamp and speaker level inputs so you can install it in almost any vehicle, even those with factory radios.

When using the speaker input, the amplifier will detect the incoming signal and turn itself on, eliminating the need to run power-up wires back to your vehicle’s receiver or fuse box.

An optional wired remote lets you control bass levels from the driver’s seat. S-A60M control panel.

  • Power Supply MOSFET: MOSFET is an electrical switch that allows the flow of electrical current. It precisely controls output voltage and current by eliminating output current sensing loss and eliminating all secondary feedback circuitry.
  • Low and High-Level Inputs: Low level (RCA) inputs are measured in voltage. The high-level input ( cable) is measured in watts. They both basically carry the signal from your receiver to your amplifier to your kicker speakers.
  • Variable Low-Pass Crossover: The kicker subwoofer reproduces sound based on a range of different low-end frequencies. You can set the exact sound specifications for bass frequency reproduction
  • Switchable Bass Boost: With Bass Boost you can adjust the deep bass in the boost area to your liking.
  • Variable input gain control: The gain control is not used to adjust the volume. It simply adjusts the signal strength coming from your receiver and going to your amplifier.


Rockville dB13 3000 Watt Peak

rockville db13 3000 watt peak

Rockville dB13 is a mono amp with 3,000 watts of peak power and 750 watts of dyno-certified power. At Rockville, we offer in-car audio at the best price.

That’s why we want to make it easy for you to compare our products with all brands on the market.

Top ratings can be used to compare against brands using top ratings like Boss and Power Acoustik while Dyno certified RMS ratings can be used to compare against top brands like Kicker, Rockford, Alpine, etc.

A trick to determine the actual power of a car amp is to multiply the fuse rating by 10 to determine the actual RMS power. This formula almost always works within 20%. Rockville dB13 features a maxi fuse rated at 80 amps.

While we conservatively rate this as 750 watts Dyno Certified @ 2 ohms, this amp puts out a lot more power! This amp features a fully adjustable 12dB/octave crossover with differential circuitry.

Other features include a subsonic filter, fully adjustable bass equalizer, soft-start mute and delay technology, phase control switch, and in-dash subwoofer controls for added convenience.

Protected by full IC-controlled circuitry, Rockville dB13 features professional peak-limiting circuitry to ensure distortion-free music reproduction at all levels.

The RCA input accepts both balanced and unbalanced inputs. If there is potential for interference in the car, the symmetrical input signal is less susceptible to interference.

Rockville dB13 Booster uses top parts and components recommended by Rockville’s own engineers. This amp is the best of any series we’ve ever made.

They work more efficiently, resulting in dB sound. We make it 2 ohm stable like the most famous amps in the world from Rockford Fosgate, Kicker, etc.

kenwood kac-9106d dyno

Kenwood kac-9106d dyno Amplifiers are extremely powerful and rugged amplifiers that can deliver superior sound quality and extremely reliable performance.

When you power your subwoofer with Kenwood’s Performance Series KAC-9106D amplifier, you’ll hear clear sound with all the great tone, impact, and detail in your musical bass, from the thumping beats of the rhythm to the soft thumping of the kick drum.


Power Connection: The power and ground connections are 0.55″ wide screw terminals. The remote actuator screw terminals are 0.335″ wide. A Phillips head screwdriver or flat blade (not supplied) is required to tighten/lose the terminals.

A Spade connector is recommended. The manual lists a minimum of 10 gauge wires for power and ground, but given the 120 amp fuse rating and 65 amp current consumption specifications, we recommend a 4 gauge wire kit.

Speaker Outputs: There are two pairs of 0.335″ wide screw-terminal speaker outputs; both are connected internally in parallel, making it easy to connect two subwoofers. A Phillips-head or flat screwdriver (not included) is required to tighten/lose the terminals. Spade connectors are also recommended for the speaker cable.


Gain: To accommodate the varying signal levels of today’s factory and aftermarket radios, the KAC-9106D is equipped with adjustable gain control, 0.2-5.0 volt line level (RCA), and 4.0-12.0 speaker-level volt.

Crossover: The built-in 24 dB/octave low-pass filter has a continuously adjustable switching point from 50 Hz to 200 Hz. As this is a subwoofer amplifier, the switch is always on.

Bass Boost: Bass boost can be adjusted from 0-18dB at 40Hz.

About this item:

  • Mono subwoofer amplifier
  • 500 watts RMS x 1 at 4 ohms (1,000 watts x 1 at 2 ohms)
  • Class D amp design
  • Speaker level input with Sensing turn-on signal
  • Variable low-pass filter (50-200 Hz at 24 dB per octave)


FAQs Top Best Amplifiers for Car Audio

Who makes the most efficient car amplifier?

Alpine makes some of the best car audio amplifiers on the market. The PDX series is one of the most efficient amps on the market, and Alpine makes so much money on its massive sales (the number 1 seller of in-car audio in the US) that they can sell stuff there for less money than most products.

How many watts is a good subwoofer?

Amplified speakers around 50 watts RMS per channel – 250 to 500 watts RMS is a good starting point. A 100 watts RMS per channel system that has at least 1,000 watts RMS, or more for a sub, is not uncommon.

Does a car amplifier affect sound quality?

The car amplifier can overcome the noise when driving on the highway. Even high-quality after-market speakers will sound weak in a loud vehicle unless they have enough power to deliver optimal output. Good aftermarket speakers with greater sensitivity can deliver enough volume and clarity to stand out despite the street noise.

Do more expensive amps sound better?

When the two amplifiers sound different, at least one of them adds distortion to the signal. So, if the two amplifiers sound different, there’s absolutely no reason to assume that the more expensive one is the lower distortion one.

How do you match amps to speakers?

In general, you should choose an amplifier that can deliver the equivalent of twice the programmable/continuous power of the kicker speakers.

This means that speakers with a “nominal” impedance of 8 ohms and a program power of 350 watts will require an amplifier capable of delivering 700 watts into an 8-ohm load.
