Best 1-OHM Stable Amps For 2019

For many of us, we spend so many hours in our car, perhaps without even realizing it. For those of us who are aware, it’s entirely understandable why we’ve taken the steps to upgrade our car audio system.

After all, it doesn’t matter whether you’re driving to work, or embarking on the road trip of a lifetime, there’s no feeling like cruising down the open road with your favorite playlist blaring, ultimately immersing you in the moment.

However, when it comes to the actual setup of your audio equipment, it’s all well and good upgrading your speakers, but you’ll need the power behind them to ensure they perform to the best of their ability.

This, of course, means investing in an amplifier. Many vehicles will power your speakers on a certain wattage, which causes the speakers to move. But, if you’re using a 500-watt speaker, there’s no way that your car will be providing this much power, meaning they won’t play their loudest or clearest.

An amplifier literally amplifies the amount of power your speakers have, meaning you’ll be able to crank up your volume and groove out to those funky basslines. With this in mind, today we’re going to zero in on stable 1-ohm amps that are ideal for you.

To cut a long story short, the lower your ohm rating, the more power your speaker will have. Obviously, 1 is as low as you can go, so we’re going to be diving into the depths of raw power. Of course, stable means you’ll be handling this power in a safe way.

We’ve searched far and wide for the best 1-ohm stable amps out there, narrowing our selection down to just four of the best. These are high-performance amps that are ideal for bringing a new lease of life into your in-car audio system. Let’s jump straight into it.
