The Best 4 Channel Car Amplifiers – Buyer’s Guide and 5 Excellent Choices
Deliver to home. Brand Find a brand. Boss Audio System. Planet Audio. Power Acoustik. Rockford Fosgate. Genius Audio. MB Quart. Unique Bargains. Studio Z. MTX Audio. JL Audio. CT Sounds.I love 4 channel amplifiers!
In my opinion, 4 channel amps are some of the most flexible and the best value. However, finding the best 4 channel car amplifier can be tough! In order to help you find the best for your money I wrote a helpful buyers guide.
They do share a few differences, however. They too use a single power supply to provide a higher output voltage, stepped-up from 12V, to drive the speakers with more power than is possible with only 12V like factory systems. Following this, they contain 4 independent audio amplifier sections which these days are normally designed in such a way that each channel pair can be bridged for additional power if desired.
Some have features such as a bass boost control that may be used only for 2 of the 4. A 4 channel amplifier is basically the same as a 2 channel amplifier with 2 additional audio channels in a more compact design. You can configure and easily reconfigure many different types of sound systems in your car.
When adding a 2nd amp, the possibilities are even more extensive! I recommend an amplifier with built-in high and low-pass crossovers. Technology has improved a lot in the last several years when it comes to car amplifiers. A class D amp works by switching the transistors that create an audio waveform incredibly fast, saving energy and bringing heat levels down to an incredibly low level. The good news is that a well-designed amplifier of this type can have great sound quality.
Highs are crisp and bass is tight and punchy, just like older designs. For most people a 50W RMS x 4 amplifier is fine, as it provides sufficient volume and bridging the amp generally provides around W into 4 ohms, which is sufficient to drive a subwoofer well for great bass sound.
For great sound with additional high-volume ability, I would choose a 75W per channel or higher model. Alpine has done additional engineering work to reduce noise in the model, and it shows…or should I say it can be heard! Few class D amps can say the same. Rockford Fosgate Punch PX4 — Powerful, all-out fantastic sound and bonus setup features If your budget allows you to spend a little more, the PX4 is one of the best on the market today.

Speaker Level Input.Finding a good-sounding amplifier can be tough. A 4 channel car amplifier, as you may have already guessed, is extremely similar to most 2-channel stereo car amplifiers. However, there are a few differences you should be aware of.
This is necessary to create more power for the speakers you use. While similar, 4 channel models are built slightly differently. This is useful if connecting to a head unit with only 2 channels available in order to drive 4 channels of power. Some 4 channel amps are configured slightly different than others and have additional options like bass boost or crossovers that can only be used for 2 of the 4 channels. These types of details vary from brand to brand and model to model.
Diagram showing the basic differences between a 2 and a 4 channel car amplifier. These supply the amplifier transistor stages which are fed with the signal from your stereo. This basically just amplifies the very small signal from your stereo to a higher voltage that can drive speakers with a lot of power. Note that 4 channel amps are usually more compact than other models especially class D amps.
The best sounding car amplifiers have a number of important features you should be aware of before buying. The signal-to-noise ratio SNRrated in decibels dB is a way comparing the amount of audio signal to the level of noise signal in a car amplifier.
Ideally the amount of noise will be low compared to the audio signal level. A 4 channel amplifier with good sound quality will have a number around 90dB and above. The best, depending upon the rating used, will be dB and higher. Good amplifiers have a higher signal-to-noise SNR ratio. Generally speaking, the higher the number, the better. Amps with great sound quality tend to be listed as having an SNR of 90dB and above, in my experience. Some of the best list their specs at dB and above.

However, a good amp is designed to keep the noise low and the music signal high.First up are 2 Channel amplifiers. The Class type refers to the circuit configuration. Class A and Class AB amps are designed for sound quality and are ideal for both subwoofers and speakers.
Class A amplifiers are an older design and feature transistors that always have current running though them regardless if the amplifier is receiving audio signal or not. Class AB shares a similar design however in this case the transistors ONLY have power running though them when the amplifier is receiving audio signal.
A Class AB amplifier will run more efficiently and cooler. Remember anytime an amplifier is generating heat that is a by product of wasted energy. For most amplifiers made today the standard is now Class AB. Most 2 channel amplifiers feature a built in high, low, and full pass crossover which is ideal for running either full range speakers or subs however not both at the same time.
Bridging refers to the ability to combine the left and right channel into a mono output to produce more power. Keep in mind though most amplifiers only handle down to a 4 Ohm bridged load. Since bass is non-directional there is no left and right.
The human ear cannot distinguish where bass frequencies are coming from which is why when a subwoofer system is installed in a trunk it does not actually sound like it is coming from the rear. This is an example of a 2 channel amplifier running mid range speakers and then a sub configuration. Keep in mind you can run most 2 channel amps down to a 2 Ohm stereo load to achieve more power. So in theory you can run both your front and rear speakers using two sets of 4 Ohm aftermarket speakers.
Next we will look 4 and 6 Channel amplifiers. These tend to be the most versatile type of amplifier and can be used for many different applications. Most 4 Channel amplifiers will also include a built in low, full, and high pass crossover.
You also have the ability to bridge the front two and rear two channels or you can run a combination of the two, The front two channels and rear two channels actually feature independent crossovers and gain adjustments.Here at Walmart.

Boss Audio System.The Golden Globes nominations, which will be announced Monday morning, will add momentum to certain races, without being at all predictive.
The Screen Actors Guild nominations, which follows December 13, will have more impact. While the SAG nominating committee, which changes every year, tends to be a tad more mainstream than the Oscars, they are more predictive than the Globes, as they come from inside the film community.
There are always changes among the Oscar nominees from SAG and Globes Academy voters usually add some classy additions to the mix but the winners are usually close. The SAG Ensemble award, especially, often presages the eventual Oscar Best Picture winner. Those who land noms from SAG alone are more likely to land an Oscar nod than from the Globes alone. Land both groups, and you have better odds of landing an Oscar slot. Those who get neither reduce their chances.
That said, expect a few surprises among the nominations. Or does HFPA darling Lawrence sneak in. The Globe is hers. Veteran Holly Hunter could sail through with the spoiler win. And the Globes voters could go with Armie Hammer over Stuhlbarg. If Joe Wright or Denis Villeneuve get in over Americans Gerwig or Spielberg, there could be no Americans in this category.
