How to Choose The Best Car Amplifiers under $100 for You?

Fortunately, amplifiers are not too hard to understand, so let me walk you through choosing the right amp for your cars speakers. Knowing reputable brands of car amps certainly helps in choosing the right amplifier for your car. You will almost always want to get high-quality car amps for installing aftermarket speakers and subwoofers. 

If you are upgrading your cars audio system with higher-quality speakers, you do not want to be dependent on the amps found in your cars factory head unit to power those speakers. Without the amplifier, your vehicle would not be capable of handling the wattage needed to power any aftermarket speakers or subwoofers. 

You will need to find amplifiers with sufficient wattage to produce the best audio from the speakers. If you want the best sound from your car stereo, it is critical you do not power down the speakers. If you want to get the best quality sound, you should never underpower. 

For instance, if you had a 1,000-watt amp and four speakers requiring 350-watts each, then the amp could not deliver the necessary power, and your speakers could fail. For example, if an amplifier has a 100-watt x 4-channel RMS output, this will mean you need one speaker with a 100-watt RMS rating (or 4 speakers in that case, each with a 100-watt rating). It would be best if you could pick out your speakers first, and from the specifications of the last one, you could easily determine the minimal power required by the amplifier. Then, I will show how you can pair your amplifier to your speakers, based on the wattage, the RMS vs. peak, speaker efficiency, and whether or not you have any extra subwoofers. 

Whether you are starting out fresh, or upgrading; or looking to power component speakers or larger subwoofers, choosing the right amp is the key to your success. Choosing the best amplifier for your vehicle, home sound system, or professional audio application can be challenging. An amplifier that is both powerful enough and the right fit for your other components will have a dramatic impact on the sound coming out of your cars stereo. Beyond that, if you wanted to get more than two sets of speakers and two subwoofers, you will need to go for more than just an amplifier and reconfigure the way you configure your cars audio system. 

The Rockford Fosgate R500X1D takes your cars stereo system and audio quality to another level thanks to its rating of 500.0 Watts per channel at 2.0 Ohms RMS. This ultra-powerful 5-channel, D-Class, automotive sound power amp is capable of producing 100 Watts x 4 + 550 Watts in 2 ohms. This BOSS Audio R1100M Riot is a best 4-channel car amp which comes with a peak output of 1100 Watts in 2-Ohms and a peak output of 550 Watts in 4-Ohms. Now you know the amplifiers RMS Power rating is a more accurate measure of the output power, you can use this as a tool for properly matching an amplifier with the speakers(s) and subwoofers that you wish to use.
