In simpler words, if you use a 5 channel sub in your car, it’ll power your 2 rear and 2 front speakers plus the sub. If you use it in your home audio system, it’ll power all the (4) speakers plus your sub.

Some of the key benefits you’ll get from using a good-quality 5 channel amplifier include:

  • Premium sound quality: doubtlessly, the greatest benefit of investing a 5 channel amp is that it serves you with excellent quality, clean sounds with minimal background noise and distortions. The secret to the amp’s top performance lies in fusing the two amplifier technologies (AB and D).
  • Save more space: since this amplifier combines up to 2 amps into one, it saves you the need to invest in 2 separate amplifiers. This way, it’ll save you a great deal of space in your home theatre room or car cabin/trunk.
  • Get value for money: if you do your maths, you’ll discover that investing in a single amp is more economical than juggling between two devices trying to achieve your desired audio output.
  • Enjoy a dedicated subwoofer channel: yes, a 5-channel amplifier also powers your sub in addition to your speakers. Remember, a subwoofer is more powerful than your regular speakers, which explains why it requires a dedicated single channel.

What Makes The Right 5 Channel Amp?


Different channels come with different wattages. This rating is clearly indicated on the product, so it’s readily available and easy for you to read.

When looking for an ideal amp, you want to ensure that its maximum wattage matches the power needs of your audio system speakers plus the sub.

For instance, if your system has 4 speakers, with each requiring 300Watts of power, the total power requirements for your speakers is around 1200Watts.

5 Channel Amp

In this case, you should look for an amp with around this Wattage rating.

Calculate the total wattage of the speakers that make up your system plus the sub and let the value you get guide you into picking the perfect amplifier.

RMS power output

For starters, RMS is basically an abbreviation of Root Mean Square. Expressed in Watts, RMS refers to the continuous amount of power a given amp can produce.

You might not know this, but RMS will give you more light into the performance of amp than the peak power rating which most people tend to focus on.

Make sure you check the RMS of the amplifier you want to buy and ensure it matches your unique audio system speakers and sub powering needs.


The perfect 5 channel amplifier should also be bridgeable. This enables you to fuse several amplifiers into one.

For instance, you can configure your 5 channel amp into 3 channel amp plus subwoofer.

The overall benefit of bridging channels is increased versatility and power. It helps you add more speakers or even a larger sub to your audio system.

Low and High pass filters

The perfect amplifier should also come with the low and high pass filters functionality.

The low pass filters are usually helpful for the subwoofer channels as it blocks high frequencies from reaching the sub. This means only low frequencies go through, resulting in richer bass output.

5 Channel Amp

The high pass filters do the exact opposite. They filter low frequencies from passing reaching your full-range speakers. This enables you to enjoy cleaner and more precise audio signals from your system speakers.

Gain and bass boost

With the gain knob, you can hassle-freely match your system’s output voltage with that voltage output of your amplifier.

This is a crucial feature given that some audio systems have higher voltage output than others.

By matching the voltage outputs of both your system and amp, over-amplification is prevented—ensuring output of distortion-free sound signals only.

While still on it, the bass boost function is also as helpful as the gain. It prevents over-amplification for the sub channel, for quality bass output.


I’m assuming you have already witnessed in the out top-rated 5 channel amp review section how the price of these products can greatly vary from model to model.

With this in mind, coming up with a reasonable budget is crucial to help you narrow down your list.

If you’re working on a tight budget, then you should be able to find a good amp for less than $200. Most models in this cost bracket offer you the basic functionality and sometimes low sound output.

If you set a budget between $200-$800, then you should be ready to take home some of the best and highest rated amplifiers—bearing top-quality build, increased power output, higher efficiency, and extra features.

As with any other sound equipment, the higher you climb on the price ladder, the fancier the amplifier becomes.

Extra features:

  • Peak power: this indicates the highest power a given amp can output for a short period of time before getting a short out.
  • Amplifier inputs: amps that come with more input options are better in that they enable you to easily hook them to nearly any audio system, including the factory and aftermarket models.
  • Warranty: a good amp should also come with some guarantee. This is a good sign of the manufacturer’s level of confidence in their product performance.
  • Brand: an easy shortcut to getting a good-quality amp with an impressive performance is shopping from top brands like Kenwood, Planet Audio, Alpine Electronics, Rockville, to name but a few.

The gain knob helps you match your amp’s input level with your receiver’s output level, reducing distortions and background noise in your sound signals.

Follow these steps to use your amp’ gain function:

  • Disengage all the filters and bass boost on your amp. Turn the gain to low. As for the receiver, set all the EQ presets and tone controls to flat.
  • Play your favorite track (something you’re familiar with) and increase your receiver volume until the sound gets distorted, then turn down the volume a bit to clean the sound.(in case you don’t get any distortion, even at full volume, set your receiver to volume to ¾ full).
  • Now turn your gain knob until the sound starts distorting, then turn it down a bit to obtain a clean signal.
  • Adjust your receiver volume to your preferred loudness. Be sure to continue playing your favorite track as you fine-tune your system.
  • Now use the high pass filter to eliminate the low notes from your full-range speakers. And use the low pass filter to remove the high notes from your sub channel.
