OK so finally got my speakers in and wired correctly, and hell yeah does it sound good! Infinity Kappa 62.9 full range in the back, and Kappa components 60.9i up front. I had to downgrade the tweeters for the front, just becuase the ones that came with the set were bigger than I wanted. Went from the 10.9i to the 10.9t. Sounds is awesome. Darn good bass, no thumper but you wouldnt expect that from door speakers, and nice crisp highs. Very happy with the setup. Here are a few pics

Stock woofer vs Kappa full range for the rear door



Tweeters that came with the set, the 10.9i vs stock tweeter



10.9i vs 10.7t tweeter, can see the size difference



I gotta say too, after hearing these tweeters, its amazing how lousy the stock ones really sound. Its also crazy how the stock woofer weigh next to nothing, amazing they didnt rip to shreds on the first ounce of bass thrown at them. Easily the cheapest stock speakers I have seen in a good long time.

 

Still using the stock head unit?

 

No using an Alpine CDA-9887, but even if I was using the stock unit I would imagine the sound would still be greatly improved.
