Most people assume that their car’s OEM audio or their new aftermarket stereo with 50 peak watts per channel is sufficient for a nice sounding system. The reality is that most ratings don’t match the demands of an aftermarket system, whether it’s an OEM system with ‘300 watts’ or an aftermarket one with 18 RMS watts per channel. This can result in poor quality or even speaker damage.
Using the right amount of electricity to power your speakers (aftermarket or not) may make a HUGE impact in the performance of both subwoofers and speakers. It doesn’t matter if you have the best speaker or subwoofer in the world if you don’t have enough power.
Allowing power to be a bottleneck in your system is not a good idea. Purchase an amplifier that will give your car audio speakers the strength they require to generate the crisp, clear sound you desire. A top-rated amplifier is a must-have for any great car radio system, whether you’re using high-performance component speakers, subwoofers, or OEM equipment.

Frequently Asked Questions
What does a car amplifier do?
A car amplifier, in simple terms, amplifies the sound from your head unit to your car speakers. Different speaker configurations will necessitate different output connection choices and power outputs. Mono, 2-channel (or dual), and 4-channel amplifiers are the most common amplifier kinds.
Mono- Provides power to a single item and is best used in conjunction with a subwoofer. Two channels are the very minimum for a full-range 2-way or 3-way class speaker, making them perfect for a sub and satellite setup (left and right, and bass).
The 4-channel system provides the most flexibility since it allows customers to employ two pairs of speakers in conjunction with their subwoofer for a more dramatic and full-range sound. If you buy a 4-channel but only need a 2-channel setup, you can bridge it and still have the option to add a second set of speakers later.
How does a car amplifier work?
An amplifier is an electrical transistor circuit that controls the flow of electrons using capacitors and resistors. It takes a low voltage signal and utilizes it to regulate a much higher voltage signal, essentially amplifying an inaudible line-level signal from your head unit (vehicle audio) until it can power your speakers’ drivers to move their cones. Because most head units aren’t capable of driving a loudspeaker, an amplifier is the only way to get a full-range sound that’s free of buzzing and less synthetic for a lengthy road trip. This is especially true for individuals who enjoy their bass booming; a subwoofer requires a lot of power to operate, and a basic car audio isn’t up to the task.
You’ve undoubtedly noticed that the bulk of the ones we’ve looked at have a MOSFET power supply. Metal Oxide Semiconductor Field-Effect Transistors is an acronym for Metal Oxide Semiconductor Field-Effect Transistors. It’s a field-effect transistor with a gate isolated from the body by an insulating layer, allowing the device’s conductivity to be adjusted by assessing the voltage needs. When the voltage is below the threshold, conduction between the terminal and the drain source is minimal or non-existent.
This means they can smoothly and safely adjust the voltage to amplify and switch electronic signals. With a MOSFET power supply, your system will function efficiently, with no wasted energy, and you won’t be able to overload your speakers, which will result in distortion, overheating, shorting, and long-term damage.
