Alpine SPX-107R 4″ Speaker Review
Alpine car speaker reviews. A friend of mine came to me recently about getting some 4″ speakers for her car. Price was not really a option for him he just wanted to get a loud pair of component speakers. Of course my first suggestion was to cut out the door panels to either 5-1/4 or 6-1/4 but he did not want to make the modification to his car. So we went to our local car audio dealer to look around and listen to a few of the 4″ speakers. He set his eyes on the Alpine SPX-107R’s. I was not to surprised because he is a big alpine fanatic.
