Best Car Amplifier 4 Channel 2020

If you are looking for car amplifier 4 channel I want to help you. The tools we buy come with standard and simple music systems. If you are a fan of quality, clean sound and powerful bass system, we need to invest in extra equipment. Below, we have listed 3 of the most preferred brands and models for you.

1. Kicker 46CXA3604 Car Amplifier 4 Channel

Kicker CX360.4 car amplifier 4 channel

Using Class A/B power, this amp features a variable bass boost with KickEQ, giving you as much as a 6dB of extra bump. A powerful 12dB crossover is also included, letting you quickly tune your system to perfection.

CX-Series Amplifiers accept up to 40 volts (400 watts) of speaker-level input signal. This kind of flexibility both makes line-out converters unnecessary and optimizes your sound quality at the same time!

Highly efficient heat sinks keep the amp cool with a sophisticated new look, while KICKER’s FIT+ (Fail-safe Integration Technology-PLUS), gives you outstanding noise rejection - even with premium factory audio systems.

This CX-Series Amplifier delivers as much as 90 watts into four full-range channels, or 180 watts into two bridged channels.

Customer questions & answers

Question: Whats the difference between this model and this one kicker 46cxa360.4t?

Answer: The 360.4T is just denoting a different production facility. It is the exact same amplifier. 

Question: Is this good to use on 4 separate 6-1/2 kicker CS series speakers rated for 300W max?

Answer: You really need to know the RMS (continuous power) rating of the speakers. Without knowing the RMS rating it is hard to say. However, I can tell you that this car audio amplifier performs very well with my two Kicker 3-1/2" and two Kicker 4"x10" speakers.

Love this car amplifier 4 channel it putts out good power and sound.

2. Alpine MRV-F300 4 Channel Car Amplifier

In 4-channel mode the Alpine MRV-F300 delivers 50 watts RMS to each of your car's front and rear speakers, making for some sweet sound on your drive. You can also run this amp in 3-channel mode, powering a subwoofer with 150 watts RMS while driving a pair of full-range speakers with 50 watts each. If you need a good amp for bass, you can switch the amp to 2-channel mode and send up to 150 watts RMS each to a pair of subwoofers.

The MRV-F300 car amplifier 4 channel uses a technology called Enhanced Shutdown Performance, which rolls back the output a bit when the amp threatens to overheat from playing at its limits too long. Instead of shutting down completely, it continues playing your music, until it cools enough to return to full power.

High- and low-pass filters put you in command of the frequencies that reach your speakers, while a bass boost lets you apply some extra low-end punch. The car audio amplifier includes preamp- and speaker-level inputs, so you can install it in almost any vehicle, even one with a factory radio. If you're using the speaker-level inputs, the amp senses an incoming signal and turns itself on, eliminating the need to run a turn-on wire back to your vehicle's receiver or fusebox. If you're a tweaker, you'll appreciate the end-piece terminal covers that can be snapped in and out without the need for any tools.

Question: Is this amp auto power on when there’s a speaker input?

Answer: Yes, the amp has auto-sensing remote on when using the speaker inputs.

Question: so this amp doesn't have seperate gain controls for the front and rear channels?

Answer: Yes, there are separate gain controls.

Question: can this amp handle 4 infinity reference 6.5 to there maximum power?

Answer: Yes, this amp definetly has the power to crank 4 61/2 speakers. I currently have the amp powering 2 alpine 6x9's in the back and 2 alpine 6.5 in the front. It sounds wonderful, the more volume you give them the clearer they sound. You need to remember that you will also have more power coming from the car stereo as well.

Customer Review

I bought this car audio amplifier to power 4 JL audio speakers. The Alpine head unit I have provides a maximum of 18 watts RMS/channel. This 4 channel amp helps the head unit power the speakers by adding 50 watts RMS/channel. And the added power is clean and precise. I can detect no hum, static, or distortion, even at high listening levels.

This car amplifier 4 channel is a bargain. I would buy it again without hesitation. If you are looking for good, clean sound, look no further. This one will not disappoint.

Customer Review

Awesome amp!! This 4 channel amp works perfect for my two selenium D-250x and 2 selenium super tweeters. Very powerful, I have the knob barely passed minimum and my drivers are SCREAMING, that powerful. I also have a Taramp's 2500HD pushing 2 Eros 450 rms and I couldn't be happier with my set up. Can't go wrong with Taramp's. Thanks guys!
