Query: Polk is the best!

If you are thinking about buying these speakers, do not hesitate. I have used only Polk Audio speakers in my vehicles for the past 4 years for good reason. They are not only the best sounding speakers I have come across, but also the most durable. If you set these up in your vehicle and add a small sub-woofer (mine is 8" Bazooka), you will not believe how good it sounds. I can't recommend these enough. Amazon also has the best price I have found on these.
