I would suggest going to the component (seperate tweeter and woofer) Infinity's in the front and go ahead and replace the stock woofer and tweeter in front and replace the rear woofers with the speakers you are referencing, just a thoughtThe performance difference between the stock tweeters and the Infinity's tweeters has to be heard to be appreciated it is a huge step up definitely worth the little extra cash for the fronts in my opinion.
