Just wanted to write another review on the 8 inch 600 watt subwoofer. I have had it for a month now and broke it in slowly as recommended. I noticed from the beginning that it didn't sound as clear or hit as hard while it was breaking in and loosening up. Now it keeps sounding better and better each and every day. It hits really good and picks up the lows very well. I am in love with Boss speakers now. Just ordered a 12 inch for the fun of it and am excited to hear what it can do! Thanks boss for making a very affordable speaker sound so very good!
