Here a couple I got recently to put into a car and they are unbelievable. <BR> <BR>Illiusion 6 inch at solen.ca <BR>Scan speak revelator tweeters at madisound.com <BR>6.5 subs at ddaudio.com <BR> <BR>Due to space limitations, I am using the 6.5 digital designs as subwoofers and they are amazing. They play as low, smooth and hit as hard as any 8 inch subwoofers I have ever heard. They are also only $ 129.00 a piece. <BR> <BR>The Illusion carbon series are incredible for tight space limitations, specially at the price. <BR> <BR>I also use 130 tweeters from Morel that you can find at madisound.com. They can build you a crossover to meet specifications of the speakers you choose. You build a custom speakers array that will out perform any component system under $ 750.00 to $ 1,000.00 through these sources and save a whole lot of money.
