Best Mini Car Amplifiers: Buying Guide
Assuredly, it isn’t easy to buy or find the best amplifiers for your vehicle, several factors matter are necessary to consider before buying. We did in-depth research and compiled a few factors to resolve this issue. This list contains power rating, car amplifier type, channel number, size of an amplifier, and noise specifications; before buying, overview it.
Channels
There are a total of six types of car amplifiers that you may find in different stores; each Class is categorized on its amp power measuring capability. Single and multi-channel amplifiers are available in the market; it’s up to you which one to choose according to your bass expectations. Let’s have a look at some channels.
Mono Channel
The Mono channel type is also known as the Class D amplifier because it produces better and more unmistakable sound than its dual-channel amp version. Mainly, this type contains multiple transistors and an on and off power system. No doubt, these are simple but performed well in vehicles.
Dual Channel
This type offers up to two speakers and power up subwoofers and makes their sound outstanding. You may use them in your hatchback cars and any other vehicle. It’s too small, so it is effortless to fit underneath the car seats.
Three Channel
A three-channel car amplifier contains two various types of circuitry in a single amplifier. It perfectly fits into the vehicles with almost no extra space demands.
Four Channel
With this amplifier, you may power full speakers set easily, as it supports powerful speakers, so it needs a large space room. Therefore, you have to put it in the car trunk where it provides you bashing performance.
Five Channel
It is just the same as the previous one; however, adding a subwoofer is an adding feature. For blasting the party, this type is best suitable for cars.
Six Channel
This type is rare in the market, as it demands ample space. So we preferred 2-Channel and 4-Channel primarily by keeping space issues in mind. And that’s why we only reviewed 2 and 4-Channel mini car amplifiers.
Another factor to consider is the type bases on the class of an amplifier. There are 3 classes for mini car amplifiers.
Class A
It’s the most common class. It has a linear model, so it runs with one transistor. Also, A class amplifiers are primarily available and budget-friendly.
Class B
Amplifiers consisting of two transistors belong to class B. This class is better than the Class A amplifiers in terms of transistors numbers, giving you a better sound experience. However, with this, their good distorted chances raise due to crossing over.
Class D
Class-D amplifiers are primarily reliable and more durable amplifiers than all other competitive classes. However, it holds a single transistor and has a linear operating system.
Power
Power indirectly relates to the bass of an amplifier, and a powerful amplifier provides a heart-touching bass to its users. Moreover, an amplifier has an RMS rating and a peak power that determines the total capacity of that particular amplifier.
Mostly, recommended and preferred RMS rating is 50-watts for each channel. Although, you can choose it on the base of amplifier size. For instance, a 50-watts RMS for each channel is enough if you have a small sports car, hatchback, or a small-cab pickup. This RMS is enough for overcoming road noises and it enhances clarity to the music.
We prefer you to look for those amplifiers which have a top 50-watts RMS rating at least. We’ve mentioned the power in each review thus get the one suitable for you.
Take a step up and choose 75-watts RMS for larger vehicles or more volume. Furthermore, for more eye-popping volume and the more significant bass impact, you should go for a 100-watts RMS per channel.
Sound Quality
Adding an amplifier or bass system in your car means you don’t compromise on sound while listening to the music of your choice. Sound is a significant factor to consider while buying car amplifiers.
Usually, the dual-channel amplifiers produce distortion, so the sound deteriorates. However, a multi-channel like a 4-channel amplifier is the best solution to overcome this distortion problem.
Size
As you are looking for a car, then definitely size matters a lot. Cars do not have enough space for an additional device. So you have to choose only those amplifiers which easily fit underneath the car seats. Although, you can choose a large size if you have considerable space in your car.
Wiring
Another essential factor to consider is wiring. Oxygen-free copper cables are ideal and most recommended for this purpose. These cables offer a smooth power supply flow from your car battery.
Moreover, the specifications of a wire gauge is another vital parameter in providing smooth power flow. Using eight gauge wires for up to 500 watts RMS rating power is incredibly best. Besides, you may use four gauge wires for 500-watts to 1000-watts RMS. However, for 1000-watts to 1500-watts, RMS 2 gauge wires are the best to choose.
Warranty
Everyone look for a product with warranty as investing a considerable amount in your favorite hobby also matters greatly. Therefore, be sure that what you are looking to buy is a warranty product. In case of authorization, a product doesn’t work well, you can verify it from the seller.
If you couldn’t find them, then locate the dealer and call the company. Or if it isn’t authorized, then you should think twice before making a purchase. However, almost all amplifiers listed above have warranty, so you don’t need to worry about it.
Conclusion
It isn’t easy to recommend a single product becuase the suitable amplifier depends only on your speakers needs. We recommended the researched top reputable brands for you; all of them offer a warranty and several stunning features.
