The Best Competition Grade Car Amplifiers for 2020

Most people think that it’s easy to upgrade a car’s audio system. Many believe that all it takes to make the car’s audio system sound better than stock is to upgrade the factory speakers, and that’s the end of that. But that’s not entirely. Although it helps to have good speakers, investing in a good aftermarket amplifier can make even more of a difference.   

Just ask anyone who’s installed competition-grade car amplifiers before, and they’ll tell you just how the right car amplifier can take your car’s audio system to the next level.   

With that said, we’ve decided to up the ante in our roundup.  

Instead of just recommending the best car amplifiers for 2020, we went and rounded up the best competition grade car amplifiers for 2020.   

The “competition-grade” distinction is important. This is because these are not just your typical run-of-the-mill car amplifiers. They’re meant for sound-offs and other competitions. They’re meant for the best of the best, or so to speak.   

Top 5 Best Competition Grade Car Amplifier

Built to perform at a reasonable price, the Skar Audio RP-1500.1D is no slouch.  

One could argue that the Skar Audio is the best competition grade car amplifier for 2020. Why? For starters, the intricate aluminum design belies the power of the unit hidden underneath. The class D circuitry is well received. Not to mention, it also has a soft start turn on.   

Power handling is also a synch with the Skar Audio RP-1500.1D.  

On 4 Ohms, it has a power rating of RMS 550 watts x 1 channel, and RMS 930 watts x 1 channel on 2 Ohm, as well as RMS 1500 watts x 1 channel on 1 Ohm

At its peak, the Skar Audio RP-1500.1D has a rating of 1900 watt, which is just absurd.   

What makes this competition grade car amplifier even better is how compatible it is to a number of audio and electrical systems. Although installation can be quite a pain because of how close the connectors are to each other, it comes with dual speaker terminals for easy hooking and connection to two or more speakers. Because of this particular design, you can hook up multiple SK amplifiers together to power just one source.   

The internal variable subsonic filter and variable low pass filter, as well as the wired bass remote control, gives this competition grade car amplifier excellent sound quality and arguably even better control.

What You Should Consider Before Buying Competition Car Amplifiers

There are a lot of factors that you should consider first when looking for competition grade car amplifiers.

For starters, if you’re powering dual-sub setups, or you have a big foot-long car subwoofer (or even larger), you’ll want to get a competition grade car amplifier with stable 1-ohm power. Ideally, you’ll want something that you can bridge multiple output ports to for extra power when necessary.

Other factors worth taking note of are internal component shielding, coil and capacity quality, input and output options, heat dissipation, thermal protection, and more.

All of these factors play a huge role in how clean and powerful your car audio system is going to be and how minimal the distortion will be. The internal circuitry, in particular, will play a huge part in the frequency response of the amp. It will affect how well the amp reacts whenever it’s fed with low-frequency sounds.
