Looking to add some serious thump to your car audio system without turning your ride into a cluttered mess? The Blaupunkt BPA-401Mi gives you powerful bass in a package so small, it could practically hide in your glovebox. This micro Class D monoblock amplifier is made for audiophiles who want performance without compromise.

Tiny Amp, Mighty Output

The Blaupunkt BPA-401Mi cranks out a max output of 410 watts, which is pretty wild for something that fits in the palm of your hand. Need clean, consistent power? You’ve got 1 x 245W RMS at 4 ohms and 1 x 410W RMS at 2 ohms. That means you’re getting the kind of juice that pushes your subwoofer to perform without distortion or dropouts—even at higher volumes.

Slim Build, Bold Sound

At just 2.16 x 2.88 x 4.92 inches, this amp is all about stealth. Whether you're sliding it under a seat or tucking it behind a panel, the BPA-401Mi is built for discreet installations. But while it may disappear visually, your ears will definitely notice it. The audio output is rich, clean, and powerful—everything you want from a subwoofer amp.

Efficiency That Doesn’t Quit

This is a Class D amplifier, which means it’s designed for high efficiency. Less energy wasted as heat = more power where it matters. The Blaupunkt BPA-401Mi runs cooler, performs longer, and draws less from your electrical system. With a voltage range of 9V to 15V DC and musical consumption at just 18A, it's easy on your battery, too.

Clean, Controlled Audio

A signal-to-noise ratio of 90 dB means your music stays crisp, even when you crank it up. This amp doesn’t just add volume—it adds quality. The built-in low pass filter (60Hz – 22kHz) and high pass filter (10Hz – 2.5kHz) let you fine-tune the output so your bass hits exactly how you like it—tight, booming, or anything in between.

Precision Performance with Real Flexibility

Whether you’re into trap beats, rock anthems, or house music, the Blaupunkt BPA-401Mi makes sure your bass is felt just as much as it’s heard. And thanks to its total harmonic distortion (THD) rating of ≤10%, you’re not just getting raw power—you’re getting controlled, clean audio that preserves the detail in your tracks.

Built for the Real World

This amp isn’t just a spec sheet flex. It’s built tough, with a 25A fuse for protection and a solid, rugged design that holds up against the rigors of daily driving. From daily commutes to weekend road trips, the BPA-401Mi is ready to perform whenever you hit the ignition.

A Legacy You Can Hear

Blaupunkt has been an audio icon since 1924, and the BPA-401Mi is a continuation of that legacy. It's not just a box that makes things louder—it’s a precision-engineered piece of equipment made for people who love sound. You get German design, proven reliability, and sound that makes your car feel like a concert on wheels.

So if you're chasing deep bass, tight sound control, and a sleek, easy-to-hide design, the Blaupunkt BPA-401Mi is the amp that delivers—all power, no bulk.
