Buying guide

Below are certain factors to consider before buying the best car amplifier for bass:

Number of channels

One of the most crucial things to look out for is how many channels you need. The number of channels primarily implies output parts to generate exterior speakers or subs. A one channel amp is useful for driving subs only. Multi-channel amps, on the other hand, are capable of powering a sub and many speakers. 

The working of an amplifier splits between the channels. An underpowered speaker by a low-quality amp causes a distortion. So, it is ideal to buy a more significant car amp with enough power to avoid problems. You can bridge a multi-channel amplifier to get extra power to a sub, thereby gaining additional bass for your unit.

Size

Also, this is a vital feature to consider due to limited spaces in vehicles. Therefore, it may be difficult for large amplifiers to fit. Preferably, a compact but the feature-filled amp is perfect for purchase. That is because it is easy to install.

Amplifier impedance

Impedance is the active resistance of a speaker, especially car amplifiers. Meanwhile, its measurement is in ohms. If you want to improve the sound quality of your amp, then you should check this factor. Inspect the fuses to know the type they’re using for the audio unit. Meanwhile, the Best car amplifier for bass has the typical impedance wattage for your amp.

Power

Any Best car amplifier for bass should be able to deliver enough power output. The measurement of an amplifier’s strength is in RMS rating. They also use peak power to measure it. RMS rating is very crucial as it is the real power that delivers between the device channels. The higher it gets, the more power the amplifier will distribute to your unit. Thus, it will offer you louder, undistorted audio.

For an amplifier with many channels, endeavor to inspect the RMS rating of each of the channels. After that, look at the difference between your sub and speaker rating. 

Amplifier car type

You can distinguish car amplifiers through their classes. That means the kind of circuitry manufacturers use to make it and the features. There’re five main classes, namely: A, B, A/B, D, and G/H.

• Class A is the most accessible type of amplifier, and it comprises one transistor in rectilinear mode.
• Class B is more structured than A. That is because it has a set of conductors that operate in a push-pull organization. Yet, it has a higher possibility of malformation due to the structure.
• Class A/B: Mixing A and B with their transistors operate by directing current anytime there’s no input wave. But, whenever the line input comes up, a single transistor works.
• Class D transistors are more of electronic switches and provide direct benefits than other classes.
• Class G/H is a revised version of A/B and operates by running the power supply.

Installation

It could be a little bit tricky to install car amps. So, it is ideal for you to research more before installation to avoid any faults or damages.

 

FAQ

How many amps do I need for my car audio system?

In some cases, you may need a single amp for all the speakers in your vehicle. Therefore, you’ll have to use different channels on the amp so that each channel will run one speaker. Though some vehicles have four speakers yet four-channel amps are well-liked. You will get more choices with a five or six-channel amp.

What hits harder 2 ohms or 4 ohms?

A lower electrical resistance subwoofer offers a more significant sound than a large version. At such 2 ohm subwoofers provides more loudness than 4 ohms. However, 2-ohm subwoofers tend to generate poor sound quality because it consumes power.

How many watts do you need for a subwoofer?

For a factory radio, you’ll need about 50 to 200 watts RMS of power to get strong bass. Meanwhile, an aftermarket receiver requires 200 to 300 watts RMS of power. 250 to 500 watts of power are ideal for amplified speakers with 50 watts RMS for each channel.

Do more watts mean more bass?

Extra watts equal a more robust bass response. Meanwhile, Bass frequencies need additional power to get loud against mid-treble frequencies. A lower frequency requires more power to get louder. Therefore, most people choose to play their 100 or 120-watt units at a low volume inside their bedrooms. That is because of the bass response the speaker emits.

How many watts is an excellent speaker?

For a lover of uncompressed music with 90dB efficient speakers, 200 watts will give you enough power. If you like playing soft music like classical and don’t need too much bass, then 50 watts is sufficient. Horns in trucks use few watts though they’re of higher efficiency.

How do I increase the bass on my amp?       

Most importantly, endeavor to turn them off.

1. Firstly, turn down the gain, filters, and bass boost.

2. Put on the benefit until a distortion occurs. After that, back it off until you get a clean sound.

3. Modify the low-pass filter downwards to get rid of high and midway frequency notation.

4. Finally, play using the bass boost.

How do I know if my speaker has good bass?

The human ear can hear within 20Hz and 20 kHz. But, with bass frequencies under 30 Hz, one might not even feel it. Thus, any speaker is 50Hz or below is better and does not require pairing with a subwoofer.

Conclusion

Choosing the Best car amplifier for bass is not an easy task. That is because there’re so many models out there. Most of the amp in this review has defining characteristics that one must consider before buying.

Get an amplifier that has a variable low-pass filter adjustment. Thus, you’ll get better performance and be able to shape your likeness. If you’re low on budget, you’ll still get affordable amplifiers that are of high-quality.

Plan well before you make any move into the market to get this product. If you need an upgrade, check the watts to get better audio clarity. Also, you need to understand the dynamics and definitions of some parts.

Finally, this Best car amplifier for bass review and buying guide will help you decide on the best one. So, go through it thoroughly to make the right choice.
