Coming to a car audio forum, I am looking for the best in advice here. I have a 1992 BMW 325i with 5.25 inch speakers in the front and 4x6 in the rear. Now I also have tweeters and dome speakers on my dootr as well butnot sure the size. Now I am debating between a compnent system and just speakers. What I am looking at right now is alpine, mb quartz, infinity, and now focal based on what I have read so far in this forum. Any advice or experience with any of these component systems. Which would you get and why. Also which brand should I get for the rear. Thanks for the advice.
