Big sound in a small package

Axxera's Mini Series car amplifiers pack a lot of sound into a small space. Their AX350DM mono amp supplies up to 662 watts RMS of power to drive your subs, and packs all that Class D power into a package that's only 1-5/8” high and 4-3/4" wide, allowing it to fit under most car seats or in just about any tight spot in your vehicle. And Axxera delivers all this to you in a package that will fit almost any budget.

In control

The AX350DM features a variable low-pass filter to select the right frequencies for your subs. Fine-tuning with the bass boost and subsonic filter helps your subs sound their best in their enclosure and in your vehicle. Axxera also includes a remote bass control that allows you to set the bass level from the driver's seat. The AX350DM amp will give you a whole new way to make your subs happy.

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.
