Buying Guide: 3 Channel Amplifier

Before you buy a car amplifier, there are a few things to think about.

What Is The Purpose Of A Car Amplifier?

A car amplifier, in simple terms, amplifies the sound from your head unit to your car speakers. 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). 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 utilises it to regulate a much higher voltage signal, essentially amplifying and the 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.

With a MOSFET power supply, the system will function effectively, with no wasted energy, and you won’t be able to overload your speakers, which will lead to overheating, distortion, shorting, as well as long-term damage.

How Do You Set Up An Amplifier In Your Car?

Previously, amplifier installations required the assistance of a professional, and while this is always suggested and certainly desirable if you are a newbie or ill-equipped for the task, newer models aren’t too difficult to install in your automobile.

Conclusion

That concludes our guide to the best 3 channel amp. Budget amplifiers don’t have to be expensive; in fact, they’re frequently one of the less expensive components in most setups; a subwoofer, for example, will cost a lot more than the donkey that has to do all the legwork.

We also recommend getting an amplifier with a variable low pass filter adjustment, which will give you more control over your system’s workload allocation and allow you to sculpt your equalization.
