I haven't read the whole thread but imho you can't go wrong with infinity's, I'm running 605cs 6 1/2's with 1" tweeters and crossover off my regular headunit and I love them, I'm about to throw a equalizer and amp at 75watts rms a piece, I can't wait. I think right now you can find a pair of em for 80-100 bucks off ebay. worth every penny
