The Best 4 Channel Amp (Guide) – 2016 Reviews

4 Channel Amp Guide FeaturedHave you ever been riding down the road in your vehicle, and you notice that your car’s sound system doesn’t sound that great? This may be especially true if your vehicle is older or does not have a premium sound system. Even the best factory systems may be lacking a little bit, especially if you love hard-hitting bass as you’re driving down the road. In order to get the best sound in your vehicle, you have to have a custom sound system.

This includes having a powerful radio with a lot of different functions, a subwoofer (or multiple ones for the loudest sound), and an amplifier that is used to amplify the sound. For the most complex systems and the best sound around, a 4-channel amp should be part of your custom system.

What is a 4 Channel Amp?

An amp is hooked to a radio and a subwoofer and is used to amplify the sound pushed from the radio to the speaker. Without an amp, a subwoofer won’t be as powerful, and it may even sound pretty bad. A complete sound system that has clear sound and booming bass requires an amp.

A 4 channel amp is one that has four channels that can be hooked to your components. You can hook up your factory speakers to an amp for increased sound, or you can hook up your subwoofer for a more powerful sound.

What are the Advantages?

If you love music and you like listening to it loud, an amp is something that you need to add to your vehicle. With four channels, you can easily equalize the sound throughout your vehicle by using two channels for the front left and front rear speakers, while hooking the other two channels to your two rear speakers or a subwoofer. The result is a louder sound system that sounds far superior to your factory setup.

What are the Different Types?

All 4-channel amplifiers have one thing in common: They have four output channels. There aren’t different types, per se, as this is a specific type of amplifier. However, you will find that there are difference in other ways including:

Brands – There are multiple brands on the market. Those that are more well-known for having top power are typically much more expensive than an off-brand amp that produces little difference in the amount of sound in your vehicle.

Size – Most amps are small enough to fit in your trunk, but some are a bit larger. Consider the size of your vehicle before making a purchase.

Output – The amount of watts your amp has determines how loud your sound is. You should consider the wattage of your speakers and subwoofer when deciding what amp is best for your vehicle.

Features to Consider

Instead of driving around with your factory system, why not pump up the volume with a custom sound system in your vehicle? Now that you know a little more about amplifiers and why you need one, you may be tempted to go ahead and make a purchase. However, who wants to end with a product that doesn’t live up to their expectations? Before you make that purchase, keep these four things in mind before you buy.

Price
If you’re buying other audio components for your car, you really need to consider your budget. You don’t want to blow all of your money on an amplifier for speakers that produce terrible sound. You also don’t want to go too cheap, either, as you may be unimpressed by the difference in sound or distortion that is common in very cheap amplifiers. Make sure you balance quality with what you’re able to afford before you make your purchase.

Peak Power
The peak power is the maximum amount of power that can be run to an amp. For example, if your amp has a peak power of 400 watts, hooking 600 watts of components to it can result in damage. Make sure that you buy something that has enough power to fuel all of your components.

Warranty
It’s just a fact that over time, electronic devices will fail. However, this doesn’t mean that they should fail right out of the box or after just a few days of use when used properly. If your product is a lemon and doesn’t work as it should, why should you be held responsible for repairing or replacing it? If the item you purchase has a manufacturer’s warranty, you won’t be responsible for these charges, and you can get a replacement product or the repairs you need to make your amp run as it should.

Size
You don’t want your amp to take up too much extra space in your car, so you need to consider size, especially if your drive a sports car, compact car, or other smaller vehicle. Look at the overall dimensions, consider any additional components you’ll be adding (such as a subwoofer box), and make a decision based on what best fits your vehicle, along with other features that are most important to you.
