Our take on the Axxera AX490D

by Bob Bihlmayer
Axxera

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.

Mini brute

Axxera's Mini Series car amplifiers pack a lot of sound into a small space. Their AX490D 4-channel amplifier drives each of your front and rear speakers with 97 watts RMS of smile-inducing power, or it'll drive two subwoofers with 275 watts each in two-channel mode. It 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 just about any tight spot in your vehicle.

Dialing in

The high- and low-pass crossovers allow you to tailor the AX490D's output to your speakers' response. Its variable bass boost lets you add some thump when it's needed. You'll enjoy the additional control and flexibility, and you'll appreciate the price as well.
