I installed the 3-way 6X9s in the rear and am pulling 25W RMS to each and they sound very good. They aren't exactly what I would call competition series, but they can more than hold their own. I don't know how they'd sound with the stock head unit since I've never heard them with lower wattage being sent to them. Considering the cost and the limited space available in the rear panels, I decided these were the best buy. You may also go with the 4-ways as these should fit without a problem as well.
