I got these because I needed some 2 ohm speakers to replace some broken bose speakers. They are working great. Sound better than the $440 bose replacements the audi dealer wanted me to buy. It would have been nice if they had made another 4 attachment tabs around the edges to better match my asymmetric audi door mounts but that's not realistic.
