Factors To Consider When Buying The Best Car Amplifier

1. RMS or Power

RMS is the consistent and continuous wattage the amplifier needs to stay powered on. Always check the RMS rating before you make your purchase. Not having enough power for the amplifier is a big mistake.

2. Wiring

It is best to have quality wires that power your amplifier. Copper condensed wiring is the best. The reason for whether your amplifier runs smoothly or not lies in the wiring. Bad wiring can cause overheating, short circuits, electrical shortages, overloaded wires, and electrical fires. The standard consumer wire is a 4-gauge copper condensed wire.

3. Wattage

The wattage completely depends on the wattage required by all of your speakers. Every amplifier indicates its wattage rate. It is essential never to run your amplifier at its maximum power. For example, if you have a 750-watt amplifier and four speakers that require 250 watts each, the amplifier will not be able to provide the required power, and your speaker might short out.

4. Size

This factor completely depends on how much space you have in your car. Some amplifiers are big, and some are small, so check out for space in your car and the most appropriate one.

5. Bridgeable

Bridgeable means you can add more amplifiers to your system to increase the power supply. Having a bridgeable amplifier is much better in case you want to make any future customizations. By bridging more amplifiers, you can add more speakers, larger speakers, or even larger subwoofers.

6. Low-Pass Filter

The best car amplifiers need low pass filters to prevent high frequencies from reaching your speakers and subwoofers. It filters signals higher than the selected frequency and blocks them out.

7. High-Pass Filters

This filter works in the opposite way of a low-pass filter. It prevents lower frequencies from reaching the subwoofer and speakers. It passes signals lower than the selected frequency and eliminates the higher frequency signals. This filter works in conjunction with the low-pass filter.

8. Band-Pass Filter

The Band-Pass filter works with both the low-pass filter and the high-pass filter to create a continuous frequency range. The band-pass filter keeps signals constant between the high-pass filter and the low-pass filter to provide the best audio quality.

FAQs on Car Amplifiers

1. What Kind Of Amplifier Should I Get?

There are a total of six different car amplifiers. Get to know each one better to understand what's more suitable for you:

  • Mono Channel - Also known as Class D amplifiers. These produce more power than dual-channel amplifiers. This amplifier uses multiple transistors, and generally, they have an on and off switch with room for making customizations.
  • Dual-Channel - These amplifiers are great for two speakers or just enough to handle the subwoofers. Ideally, these are the amplifiers for cars without trunks or trucks. Just install the amplifier under your seat, and you're good to go.
  • Three Channel - These amplifiers provide two types of circuitry. These are ideal for SUVs without much space in the trunk or trucks.
  • Four-Channel - A four-channel amplifier can fully support a full speaker system. If you want to make your trunk audio, then this is the right choice for you.
  • Five Channel - These amplifiers are exactly like four-channel amplifiers, but they have extra power. Enough extra power to power a subwoofer too.
  • Six Channel - These are quite rare to find in the market. Six-channel amplifiers are most suitable for heavy vehicles like SUVs and Humvees. These amplifiers provide maximum power, sound, and sound quality.

2. Will An Amplifier Affect My Battery? Do I Need An Extra Fuse?

You don’t need to worry if the amplifier is wired correctly. A correctly wired amplifier won’t kill your battery. The source of power for your amplifier is the car battery; with newer and more efficient technology, it requires less energy. Getting your amplifier professionally installed is the best option to get the wiring done right.

It’s recommended to add an extra fuse on your battery for your amplifier. A fuse is designed to protect other parts of your car from damage caused by any electrical fails. The best car amplifier will already come with a fuse, but it’s best to add an extra to your battery for overall protection.

3. Where Do I Mount My Car Amplifier?

Depending on the size of your car amplifier, you mostly want to mount it in your trunk. However, some amplifiers work best when they are fixed under the seat. If you’re mounting the amplifier in your trunk then here are few things to note:

  • You have to consider the wire gauging. Get an amplifier wiring kit for additional fuses, lengthy wires, and more tools that can help your amplifier installation go perfectly.
  • Whatever you do, don’t bolt your car amplifier! Bolting your amplifier to the car chassis is going to cause some major issues. It will cause vibrations to rattle all over your car body, ruining it. It will create an aggravated atmosphere, which ruins the whole point of having a car amplifier.
  • Never mount your amplifier upside-down! This traps and projects heat, which damages the amplifier. It will overheat your entire trunk. It is said that it will produce superior sound, but it doesn’t seem worth it at the cost of ruining your car.

4. Is 2 or 4 OHM Better In A Car Amplifier?

Your music relies on the woofer and your speaker system. The amplifier is the source of power for your music. An amplifier compresses electrical currents in its circuitry, outputting different watt numbers. These different watts are used to find out the OHM.

The higher the OHM, the better. Some amplifiers even offer 8 OHM. This depends on the wiring providers of your subwoofer. If your amp produces 100 watts of power, it will produce 200 watts of power for a 2 OHM speaker.

5. What Is Max Peak, And What Is RMS Power?

Max peak is the total of how much wattage your speaker can handle in bursts. Your speaker is going to output various electrical levels, peaking at sharper points in your radio. Your max peak should be high enough to handle it.

RMS power is a measurement that shows us how much power your amplifier can run at a time. It is used to manage your most frequent wattage use.

Both of these metrics are important to consider when you want thebest car amplifier. If the peak performance can’t handle music that needs high wattage, you can damage your sound system.

Conclusion

Factory car stereos almost always have weak audio signals. With the best car amplifier, you can increase the stereo signal and volume levels that the factory stereos can’t achieve. Car amplifiers can also produce that coveted bass boost.

The best car amps are going to provide you with better tuning options. Much more options compared to the ones provided by the factory stereos. If your music requires a little tuning to sound the best, an amplifier will solve all your problems. Some amplifiers have a control panel for tuning, and others have a USB port to give access to tuning options. With different amplifiers, you can have access to sound at a range of 10 to 175 frequencies.

With the best car amplifier, you can get the best speakers and subwoofers for your car. The amplifier will help control power usage and make sure the new equipment will run smoothly. A high-quality amplifier will act as a battery for your speaker and subwoofer. Your battery alone won’t be able to handle high wattages for output and input from your sound system. Get the best car amplifier and have the most smooth and best sound experience while driving.
