Best 4 Channel Amp For Door Speakers Buying Guide

Before choosing the best 4 channel amplifier for your door speakers you should consider following options:

1. Wattage: It is important to purchase an amplifier that is powerful enough to drive the speakers that you purchase.

Generally speaking, the rule of thumb is to purchase an amplifier that has a wattage rating that is equal to or greater than the speakers that you plan to use with it.

For instance, if you plan to use 6-inch speakers, then the amplifier should have a wattage rating of at least 60 watts.

If you plan to use 6.5-inch speakers, then the amplifier should have a wattage rating of at least 75 watts.

If you plan to use 3-way speakers, then the amplifier should have a wattage rating of at least 150 watts.

2. Channels: If you plan to use only one channel, then you can purchase an amplifier with any number of channels.

However, if you plan to use multiple channels, then you must purchase an amplifier that has enough channels to accommodate the number of speakers that you plan to use.

For example, if you plan to use 2 channels, then you must purchase an amplifier that has at least 2 channels.

If you plan to use 3 channels, then you must purchase an amplifier that has at least 3 channels.

3. Class: Amplifiers are generally classified into two types, namely two-channel and three-channel.

Two-channel amplifiers are more powerful than three-channel amplifiers and can be used to drive subwoofers and full range speakers simultaneously.

Three-channel amplifiers, on the other hand, are less powerful and can only be used to drive 3-way speakers.

If you plan to use 3-way speakers, then you must purchase a three-channel amplifier.

4. Features: The amplifier that you purchase should have the features that you need.

For example, high quality amplifiers come with features like bass control knob, voltage sensitivity knob, and mono/stereo switch.

5. Brand: Brand is also an important factor that you should consider when choosing an amplifier.

Purchase an amplifier from a reputable brand so that you can avail the benefits, such as excellent customer service and support.

This is especially important if you plan to purchase an amplifier from the aftermarket.

6. Price: Last but not the least; you should purchase an amplifier that falls within your budget.
