I see many Internet stores that have different car audio equipment. I know places like crutchfield and best buy are authorized Internet dealers. How do the other guys who are not authorized sell the stuff for so cheap or get it at all? They are making a profit as well so why the huge price difference? I understand the concept of warranties and service, but it make no sense to me. If I go with store X I can save $2000 on my system. How on Earth does that happen. Either store X is turning a small profit or big "authorized" dealer is turning a huge profit. Help me understand this.
