Hey punkin,
Joe D has been a wealth of info!!!
Sometimes I still live in the early 90's when decent Kenwood 3-ways were $199. That price for components seemed decent. I believe I paid $130 for the rear Kenwood 6x8's via a relative's employee discount in the later 90's. I think the front Polk's were around $90 and are only 2-ways as well. I was thinking the components with the tweeters would be a noticeable difference over them. I also didnt know Kenwood made 6x8 3-ways. The 6x9's I had many years ago in a Trans Am with A/D/S amp and Nakamichi cassette deck were unbelievable. Incredible Bass. I checked the link to the Kenwoods for $30-they are discontinued and sold out. For $30 on a Kenwood 3-way I wouldnt even consider Infinity components. It is only more work to install the tweeter and find a place for the crossover anyway. Now the search is on to find these $30 Kenwoods. Have never been overly impressed with the Polks-but they were a definite improvement over stock. Thanks for the advice, points, etc.
