Why You Need a Car Amplifier for Better Sound?

Why You Need a Car Amplifier for Better Sound?

So, you want to improve your sound? It’s time to add an amplifier to your sound system!  It doesn’t matter if you like your music soft or booming loud, the extra power boost is going to bring your music to life, create greater emotional context to each note, provide greater impact and reveal the fine detail in each note.

Nowadays, amps are remarkably compact so you can put one in virtually any kind of car without worry about space.

What is a Car Amplifier?

An amplifier is a device that takes a weak audio single and effectively amplifies it. Sometimes audio signals are too weak to really hear them without amplification. You’ll need an amplifier to bring out the soft, subtle sounds, especially when you decide to play your music loudly. Without an amplifier, if you turn up the volume then you’ll start to hear distortion the louder the music gets, and the overall sound quality is significantly reduced.

What Does an Amplifier Do?

An amplifier can boost your radio’s sound so you don’t’ hear the noise of the road and can enjoy greater clarity in your music’s sound.

It increases the sound systems headroom so it can play blasts of music with ease and no distortion.

After market speakers will sound much better if they are powered by an amp.

A subwoofer needs an amplifier to create the bass sound waves effectively and use the power to propagate.

Four Channel Amplifier

A four-channel amplifier is available in four sizes:


  • If you aren’t in the market for a big amp but still want greater clarity in your music, then consider a small model. You’ll find ones that have 40 to 50 watts per channel. They can connect to factory writing and easily fit behind the dash.
  • A 50 watt per channel is ideal if you want lots of volume
  • A 75-watt amplifier is loud and perfect for a big vehicle.
  • A 100 watt and more per channel amplifier is great if you want your music to play at a competitive level.

A four-channel amplifier will power two speakers with each by using front channels and then a subwoofer in the rear. You can slowly build up your system piece by piece. Use a four-channel amp and run front speakers and a sub but leave the rear speakers powered by the receiver. You a then add a better dedicated subwoofer amplifier that you will then connect the rare speakers too.

Mono One Channel Amplifiers

Do you want to add an amplifier to an existing system? Then consider investing in a mono amplifier that has bass EQ along with a low pass filter to help you effectively reproduce bass notes.

You’ll need to blend your bass to create balance with your system.

When working with sub power consider the following:

  • Is your car’s factory stereo around 100 watts? If so, then a mono channel amplifier is ideal.
  • Do you have an aftermarket receiver? Then you’ll want to invest 200 to 300 watts of RMS power.
  • Use with amplified speakers that have 50 watts RMS per channel, so you get about 500 watts RMS.
  • A 75-watt RMS or higher than you’ll need 750 to 1000 watts for your sub.

You can purchase a multi-channel amplifier to run the subwoofer from a bridged channel but it’s a hassle. A multi-channel amp will fail to drive loads that are lower than 4 ohms if bridged and cannot power more than a single sub. A Mono 1-Channel amp will work with a wide range of systems while giving you filters and tone controls.

Five Channel Amplifier

If you are planning on running four speakers and a sub, then consider a five-channel amplifier. It will effectively centralize all of your controls

Adding an amplifier is a great way to truly take your music to the next level. Contact Big Jeff Online for more information. We suggest checking out our Rockford Fosgate 300 Watt Full-Range Mono Amplifier P300X1 or our Rockford Fosgate Punch 1000 Watt 2-Channel Amplifier P1000X2.
