Amplifiers

An amplifier is the powerhouse of any car audio system, taking the low-level signal from your head unit and boosting it to drive speakers and subwoofers with clarity and impact. Whether you’re adding a single subwoofer or building a full active system, choosing the right amplifier makes all the difference.

Our collection covers a range of amplifier types to suit every build:

  • Monoblock (mono) amplifiers: High power into low impedances — ideal for driving a subwoofer or a pair of subs wired in parallel.
  • 2-channel amplifiers: Can power a pair of coaxial or component speakers, or be bridged to run a single sub.
  • 4-channel and multi-channel amplifiers: Designed to power full-range speakers front and rear, with some models offering a fifth channel for a sub.

Key specs to match to your system include RMS power per channel at the impedance of your speakers (e.g., 4 ohm, 2 ohm), total harmonic distortion (THD), signal-to-noise ratio (SNR), and the amplifier’s class (Class A/B for sound quality, Class D for efficiency in subwoofer applications). Pay attention to the footprint and cooling requirements — many modern amps are compact enough to fit under a seat or in tight spaces without sacrificing output.

Browse our full selection to find the right amplification for your audio upgrade. If you’re unsure, compare the RMS ratings of your speakers or subs to the amplifier’s output, and make sure your vehicle’s electrical system can handle the total current draw.
