If you shop around you can get a $5,000 system for about half the price, if you compare it with prices in your local shops. Trust me a $5,000 system is gonna be loud and unless your going to compete, there really is no point in spending that much. Btw, installed my 3-12" RE SE's yesterday and they are awesome. I decided to get the SE's instead of the ED K's, b/c the K's were on back order and they had no idea when they would be able to ship them out. The SE's are a little more, but I'm happy as hell.
