3) High End option/Audiophile choice: CDT Audio HD-series 6x9's with soft dome tweeters, and carbon fiber speaker cone material. These sound phenominal and will have great output when you amplify them. For the $200 price with free shipping, they are hard to beat. These things also use a 30oz motor compared to the other two 6x9's that use 10oz motors, so these speakers will definitely have some kick to them! And like I said earlier, he usually hooks up people I send his way, so they may be less than that! http://www.vertexaudio.com/CDT-Audio-HD-690CFX-6-x9-2-Way-Coaxial-Set-p/cdt-hd-690cfx.htm
