Overview

Our take on the Blaupunkt GTA 470 SF

Blaupunkt GTA 470 SF power amplifier

Enjoy lots of power and superb sound, all wrapped up in a tough-looking case that'll add some style to your car audio system. The Blaupunkt GTA 470 SF 4-channel car amplifier puts out 70 watts RMS per channel, great for driving two pairs of full-range speakers or components. In 2-channel mode, you can run two subwoofers with up to 200 watts RMS of power each. The high- and low-pass filters let you contour the sound to get maximum performance from your speakers or subs.
