I bought my speakers from Liquid Trends. They are based out of Modesto, CA. The guy who owns it is a good guy and gave me what I believed to be a good price. I got a black fiberglass box (4 6x9's) for $850. Included in that price was everything I needed for installation (speaker wire, grommets, hanging clamps, speakers, and box). That price was also because they didn't have to install it (which wasn't difficult I could tell you exactly how to do it if you are at all mechanically inclined) and I picked it up from their shop. The sound is incredibly crisp, loud and clear. I unplugged all of my boat speakers because when my dad goes with us, he doesn't like the music as loud as we do. With this set up you can hear the music at the perfect level that you would have it if you had it in your car and you can also hear it wakeboarding at 75 feet out (over the roar of a 351 with pretty much nothing suppressing the sound of the exhaust). I hope this helps you out a little...
