Competition Car Amplifier – Buyers Guide

Amplifiers are designed crisp, clear, and clean sound regardless of the volume levels. However, before making a purchase, there are some things you need to know and consider.

Power Ratings

Measured in Watts, power rating determines the amount of power your car uses to deliver power to your subwoofers or speakers. There are two types of power ratings. Namely, RMS (Root Mean Square) and Peak Power.

RMS measures the amount of continuous power delivered to your speakers while the Peak Power measures the amount of power in watts available in the amplifier for abrupt and short upsurges in sound. RMS power is always lower than the Peak power.

When choosing a competition amplifier to ensure that the power rating of your amplifier matches that of your sub or speaker. Note that a higher RMS can blow your speakers.

Types of Amplifier

There are different amplifier categories to choose from. These include Mono, 2-Channel, 5 & 6-Channel, and Multichannel amplifiers.

Mono Amplifiers: Designed for low-frequency response and come with low pass filters and bass boost. The best of this fall in Class D mono amplifiers. Amplifiers in this class are more efficient, draw less current, and produce less heat.

2-Channel Amps: These have high-pass filters and are used for component or full-range speaker systems.

5 & 6 Channels: Ideal for speakers and subs located in the rear or front. They can also be used for the entire subwoofer system.

Multi-channel amplifiers: These types of amplifiers are ideal for subwoofers or full-range speakers.

Size of Your Car and Amplifier

When choosing an amplifier for your car, it’s vital to consider the size of your car. This will also help you choose the right amplifier size that will fit in the available space.

For instance, it does not make sense to install a huge sub in a small car or a small sub in a big SUV. As such, you should consider the size of your trunk, which will help you decide on the type of amp you need.

Kind of Music

Not every in-car sound system suits every type of music. If you prefer loud music with strong bass, it would only seem sensible to look for an amp that has the capability of powering bass subs and speakers.

For soft music, go for an amp that can power 4-6 inside speakers for ultimate clarity.
