About the Blaupunkt GTA 270 SF
Power and style
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.

Amp works great. 200RMS for a single sub is a good amount of power. The fact that it is bridgeable and has an electronic crossover built in makes it amazing at this price point. Used this with the Blaupunkt 12" Sub and it's a great combo. Recommended.
