Impressive sound, especially for 5.25 inches!!!

The following review is for REF5030CXAM, which is a part of the bundle you are viewing.

Loud and clean vocals. Crisp clear highs. Enhanced the sound all the way around. Brings out sounds I never heard with the factory speakers. Powered by an Alpine F-300 and running off of a Pioneer head unit.

Had my factory speakers amplified by the Alpine F-300 already before installing the Infinity set. It was already loud and clear but now its on another level. Even louder and much more detailed. Night and day difference. Good sound for a good price!
