A good car amplifier is necessary for good audio experience. A car amp can control your car speakers and subwoofers so that they can rock your car. So, it is very important to find out the right car amplifier for your speakers and best subwoofers for great car audio experience. Whenever we sit in a car, we are isolated from outside noises and a theatrical environment is created with the help of car speakers. We want to be encased in a different environment that is what car amplifier and subwoofers do for us. It basically acts as a power source system to the subwoofers of the car. Its main task is to modulate the power generated from a car battery. It will fully engineer the sound system to produce high-frequency sounds and low bass beats. They are not just limited to cars but are also suitable for SUV’s, trucks and any other vehicle that wants to get rocked.
There are two categories of car amplifiers:
- Mono Amplifiers: A mono amplifier or a one channel amplifier is usually used to power one speaker. It is generally used while adding a single subwoofer to the system.
- Multichannel Amplifiers: Multichannel amplifiers are designed to power complex sound systems. They consist of two or more channels. A 2-channel amplifier is commonly used to power 2 speakers at a time, a 3-channel amplifier can power 3 speakers and so on.

Other things you would need:
The subwoofer is the speaker dedicated to producing low-frequency sounds. A good subwoofer is very necessary for a car even if you hear a song on less volume or high, the quality of sound depends on subwoofers. Cars usually have small subwoofers which have little difficulty in producing low-frequency sound. The main factors you need to consider while buying subwoofer is the power, frequency, sensitivity, impedance, number of voice coils and size of the subwoofer.
You cannot run the system without wires. They should be high temperature resistant for more safety. Wires from 12-16 gauge in size are the best for matching subwoofers with amps.
How to match Subwoofers with Amplifiers?
It might be little puzzling to match correct subwoofer with the correct amplifier. You need to match X watts RMS with Y ohms. Amplifier’s capabilities must match subwoofer capacities. It is classified according to the channels of the amplifier. The power is divided per channel. To match them, each subwoofer must have equal power as amplifier channel. If the subwoofer is underwired, then it might not be able to perform as good as it can (although the speaker is not harmed). If it is overpowered, then speaker might burst. So, it is necessary to power up according to the power of channel. For example, if you have three subwoofers and amplifier has 3 channels. You can simply match them. But there might be the case when you have one channel and 3 subwoofers. What would you do then? It is simple. You can just attach all the subwoofers in either serial or parallel fashion. The total sum up of all subwoofer power should be equal to amplifier power. For example, an amplifier with three channels runs at 600 watts, there should be three subwoofers of 200 watts each.
How to find out the right amplifier for your automobile?
It is not an easy task to find out the correct amplifier, it can be very confusing to decide the right one according to your needs. Good subwoofers are also necessary to power up an amp but even if they don’t power up enough, u can still trust your amplifier. The amplifier can work magic for the system. Car amplifier is usually installed in the front head unit of your car, but you can also get an external one. There can be many reasons to buy an external amplifier like you want to get better sound quality or you have better subwoofers and you want an amplifier to match them. A better amplifier can give better sound quality along with more sensitivity.
There are certain concepts that need to be clear before matching a subwoofer and an amplifier. For attaining proper bass in your system, subwoofers should be properly matched to amplifiers. Subwoofer matching requires a single or multiple subs wired together either in series or in parallel but while matching with one amplifier all the subwoofers must be of the same type.Now some points need to be taken care of while matching a subwoofer with an amplifier. The first important concept that needs to be taken care of is total RMS power of the subwoofer then the final impedance of subs wired together and the type of amplifier.There are two types of subwoofers SVC(Single voice coil) and DVC (Dual voice coil), the difference between single and dual coil subwoofers is multiple wiring options parallel 4 ohm voice coil subwoofer with its coil wired parallel presents a 2 ohm load to amplifier accurate to use the RMS rating as compared to maximum power. For proper matching, RMS input rating of subwoofers wired should be equal to RMS output produced at the amplifier. To get the power range of the amplifier the values of power by 1.20 and 0.90.The problem that people face with subwoofer and speaker impedances is how to combine them using more than one driver or if the driver is equipped with dual voice core and the impedance directly effects the load of the amplifier so impedance should be proper as per the calculations If we want less heat to be generated at the output then a small load should be used at the amplifier which implies a larger resistance is required. Let’s say we have 300 Watt at 4 ohms and 600 Watt channel at 2 ohms so for least heat loss the largest load is placed at 2 ohms.
Now we need to determine the type of amplifier to be used, amplifiers like monoblock,1 channel,2 channel,5 channel can be used for subwoofer matching. Although, the best amplifier that can be used is mono-block amplifier as it is designed to output a lot of power at even a very low impedance. 2 channel and 4 channel amplifiers provide less power as output but we can bridge these amplifiers and use them but there are always some limitations in the practical world and the limitation is that in bridging we cannot use load lower than 4 ohms similarly monoblock amplifiers can match a lot of subwoofers unless and until maximum impedance is not exceeded.
These concepts and calculations are used to properly match a subwoofer with an amplifier with minimum damage to the system and maximum output of the amplifier.
Few the factors that help to choose the right amplifier are as follows:
- Number of channels
- Sound Quality
The number of channels needed?
The first step in finding the right amplifier is knowing the number of channels required. The number of channels determines the number of speakers amp can power. A mono amp can run one subwoofer. A two-channel subwoofer can run two subwoofers. A three-channel subwoofer can run three subwoofers and likewise. If we have a 2-channel amp, then we can run 2 subwoofers, 2 coaxial cable speakers. It can also be used by bridging and running one single bigger speaker.
Who doesn’t want more Power?
Power of an amplifier is measured in watts. It is the maximum amount of power that an amplifier can provide. You must match speakers and amplifier according to the power. An amplifier usually has power per channel. So, speakers should also have the same power. If you give less power to speakers, they may not be able to perform so well. If you give more power, they might burst. If you want to run your speakers as well as a subwoofer on the same amp, you might bridge its channels. For example, if you have a 400-watt subwoofer and amplifier has 2 channels of 200 watts each. Then you can bridge them together to get that sound quality out of your subwoofer. It works sometimes but in some cases, you will have to buy another mono amplifier with RMS according to the subwoofer.
Amplifier Sound Quality
If you have good subwoofers, it’s going to be of great advantage. It will add on quality. But even if you have very good quality subwoofers and you don’t have a good amplifier, it may not be of much use. A good amplifier can also improve the quality of speakers which might not be up to the mark. So, an amplifier sound quality is very important. Its sound quality depends on various factors such as sensitivity, low-pass filter, stability, the range of frequency. The quality of the components used also affects the sound quality of the amplifier. Thus, it is important to check the manufacturing of amplifier.
If you are going to set a completely new system containing both amplifier and subwoofer, then it is easy. You can simply choose the number of channels in amplifier and the same number of speakers accordingly with the same frequency. But if you are going to use an existing system, say an amplifier, then you need to see if the subwoofers you buy are compatible or not. The subwoofers should have the same power as that of the channel of the amplifier, only then they will be compatible otherwise bridging can also solve this problem sometimes.
Conclusion – Wrapping it up
You can easily choose amplifier according to your subwoofer needs and music preferences. You should prefer installing a better amplifier for a better sound quality. I hope our reviews will help you find out best amplifier for your car according to your needs.
