You have 6.5s up front and 6x9s in back. Is the price of 150 for all four speakers? On ebay you can get the Infinity References 9631i 6x9s for only $50
+shipping and up front I would get the Infinity 6010cs components for under 100 or the coaxials for only $45. You could also get the Polk Db series for about the same price. Those are the two brands I know the most and would suggest for the money. Both are great for the money, Polk has a smoother overall sound with less piercing highs, and the Infinitys are very bright speakers but have good overall detail.
