How to Choose The Best Car Multichannel Amplifiers under $50 for You?

Whether using component speakers, subwoofers, or high-end OEM hardware, an excellent amplifier is an absolute must for a quality automotive stereo. You will almost always need a top-quality amplifier for your vehicle in order to install your aftermarket speakers and subwoofers. 

For two pairs of speakers and one subwoofer, you will want a five-channel or six-channel amplifier, but you could also fit a four-channel amp and a monoblock. If you have a subwoofer in your vehicle, you will want another dual-channel amp or a monoblock. For single-voice coil subwoofers, you can either go for a stereo amplifier and bridge that to a single channel or go for a single-channel monoblock amplifier. You will want a channel per speaker unless you are adding the subwoofer into a system, in which case a single-channel amplifier would work. 

If you only have three speakers, you can leave one channel unused, and that does not affect the amp at all. If you love rear-filling audio in your car, and you want to keep the faders from front to back, go with a four-channel amp - one channel per speaker. If you want to add a subwoofer and give more power to the full-range speakers back there, then a 4-channel amplifier is your best bet. A more cost-effective way to update the audio system without changing your stereo or the factory speakers is to get a compact 4-channel amplifier that boosts power for both your front and rear speakers. 

You could opt for a 5-channel amp to power front and rear speakers, as well as the subwoofer, and you would be in full control over the output of each set. You can use a two-channel amplifier to run two woofers or two coaxial speakers, or you can combine them to run a single subwoofer or run two sets of coaxial speakers. You can typically bridge two separate channels to one mono channel for powering one subwoofer. These can be set up to power 4 speakers; you could use two channels for your mids and treble, and bridge two more channels to get a 3-channel (mids + treble + subwoofer) set-up, or you could pair two channels together to get a high-power 2-channel set-up. 

We suggest looking for multichannel amps if you are driving more than just a small group of speakers, or a single small subwoofer. A two-channel amplifier would be the practical choice if you need to only power a single pair of speakers. The number of channels that your vehicle amp needs depends on how many speakers you have in your vehicle's audio system. If you are upgrading the speakers in your car's audio system, you do not want to be dependent on the amps on your factory head unit to power those speakers. 

When it comes to 2-channel amps versus 4-channel amplifiers, your car's ideal amp depends on how many subwoofers and speakers you have, as well as how powerful they are. Five-channel and six-channel amps may be used for speakers located in the back or front parts of your vehicle. Finally, multichannel amplifiers may be used for both subwoofers and full-range speakers. Whether you are looking to power a pair of our recommended best in-car speakers or a pair of monster subwoofers in your car, you will need to have one of our best amp choices provide the necessary horsepower for your system to sound awesome.
