When you shop with us, you can get even more from your new speakers by powering them with vehicle audio amplifiers from leading brands that produce the loud, clear sound you and your riders yearn to hear.

If you’re ready to get proudly loud — and we mean really loud — step up your car’s audio system with a new or replacement vehicle amplifier. While many motorists focus on the speakers and receiver for their stereos, audio experts know the car amplifier is just as important. This device is what takes the audio signal source and makes it loud enough for listeners to enjoy. The best car audio amplifiers produce a powerful, clear, distortion-free sound at your desired decibel levels. Many factory head units come with weak amplifiers that aren’t designed to really let it all out — but we have the solution with aftermarket car stereo amplifiers at great prices to power up your system.
We’ve stocked our shelves with hundreds of amplifiers to fit every audio setup. Basic 2-channel car amplifiers will serve the needs of most drivers who only have a tweeter and woofer in their vehicles. Get a 3-channel amplifier if your system also has a midrange speaker. Amps with more channels, even six or more, are available if you’re a real audiophile. If you drive a small vehicle or have limited space for upgrades, our mini car amplifiers will make the most of what you have. These compact car amplifiers deliver big sound in a small package. Those adding a subwoofer to a factory system will likely need a mono subwoofer amplifier to do what the OEM amp can’t.
Most vehicle amps are Class A or Class AB, but we also have a growing selection of Class D amplifiers that are more efficient and produce less heat. A Class D amp is also the best option for low-frequency bass sounds — and their high-end response has greatly improved in recent years. Heading off the beaten path? Marine amplifiers can withstand the harsh conditions of off-roading.
Any size system will be louder and sound better when it has the right vehicle power amplifier. They’re available in many wattages so your setup will be like Goldilocks — not too big and not too small. Select a category and use our search filters to find the amp that’s just right. We’re an authorized dealer of leading car audio brands such as Alpine, JL Audio, Soundstream, Kicker and Infinity.
We also carry all the amplifier accessories you will need, including wiring and installation kits. You can buy with confidence, thanks to our unmatched service that includes free shipping, free lifetime technical support and a hassle-free shopping experience online or in-store.
Yes. A car amplifier will improve sound quality and increase total volume. Your music will sound clearer and more detailed at all sound levels. In particular, amps are a necessity for standalone car subwoofers that require lots of power.
Amps improved sound clarity, volume and power. They do so by taking the electrical audio source signal and making it more powerful (i.e. amplifying it) so the signal can properly drive the speakers and subwoofer. Some amplifiers also adjust the signal to make it work better with your speakers. In short, they make sound clearer and more detailed.
For passive subwoofers, the answer is always yes. Some subwoofers can work alone; these subs, known as powered subwoofers or active subwoofers, have a built-in amplifier or another power source. However, many in-dash car stereos are not powerful enough to power a subwoofer — especially if they are also powering speakers. A separate amplifier will allow you to get to most out of your car subwoofer.
Yes. All car stereo systems are built with an amp, whether it’s a weak factory amplifier or an aftermarket upgrade. To properly power your system, the amplifier should be equal to twice the power of whatever speakers and/or subwoofer it’s connected to.
In general, you need one channel for each speaker and subwoofer you want to amplify. Advanced audiophiles sometimes get amps with extra channels to give them more options.
