4 Channel Car Audio Amplifiers

Pump Up Your Sound With a 4-Channel Car Amplifier

A 4-channel car amplifier can power up your speakers or subwoofers and give you more sound clarity. There are many models that can be found on eBay. Before you make a purchase, here are a few things to know about amplifiers.

Why do amps come in different channels?

Amplifiers are available in a wide range of channels. These channels are designed to help you power your equipment. Most amplifiers are available in a 1-channel, 2-channel, 3-channel, 4-channel, or 6-channel model. The 1-channel amps are often referred to as monoblocks. If you have a lot of equipment, you will need to purchase an amp with more channels. The channels allow your component to get the maximum amount of power boost without damaging the equipment. There are some components that can share a channel but most will need a separate channel for the best results.

What components can connect to a 4-channel car amplifier?

You can connect any piece of stereo equipment to this amplifier. Some equipment can share a channel. Woofers and tweeters do not need much power. They often are connected into one mono channel. Speakers need a channel for each unit. If you have four speakers, you will need a 4-channel amplifier. Any component that needs a power boost can use an amp. Some of these components include:

  • Speakers
  • Subwoofers
  • Tweeters
Where is the ideal place to install an amplifier?

If you are looking for a good place to install an amp, you need to take a few measurements of your vehicle. You want a place where the amp has enough air around it. If you install it in a tight space, the amp will not properly dissipate heat and could shut down. Many people choose to install an amplifier under the seat in the rear area. This space allows the amplifier to be hidden from view and remain close to the stereo system. The trunk is another common place for installation. This area has enough ventilation room for the amplifier.

What is bridging?

If you want to combine the amps four channels into two channels, you can do this in a process known as bridging. A 4-channel amplifier can be bridged to double the output of power. This process drives more power to your cars audio components. Many people choose to bridge their amplifiers. An amplifier with four channels can be bridged into two channels to power the speakers or subwoofers. The process is simple as you just need to move the speaker wire into different channels.
