Procedure I followed for replacing speakers in my 2011 Sport. I just did mine this morning following the below instructions. It took me about two hours to do all four speakers and the two tweeters. The replacement speakers I used were 77Kick10's and the Tweeters are JW-JKTWEET's. I purchased all components from Quadrartec. The instructions that come with the speakers are more complicated than need be. Instead of removing 6 bolts per side, there are only 3 on passenger side and 4 on driver side. Also, there is only one under-steering wheel panel to rotate down, and none on the passenger side. For driver side, just remove panel below steering wheel, remove four 7 mm bolts, remove side panel, bend dash panel out (don’t worry panel will not break), remove two speaker enclosure side (brass) bolts and remove bottom (third) speaker enclosure 10 mm black bolt. Unplug speaker box and remove it. No big deal at all. It's better to pull the entire speaker enclosure to replace the speaker. Reinstall just reverse process. Passenger side was even easier. Remove glove box door, side panel, and two 7mm bolts and one 10 mm black bolt. Bend panel outward, remove speaker enclosure as above, and slide box out. Sound bar speakers replace the same as previous models using T15 Torx bit. The Tweeter replacement was easy following the detailed instructions tat cam with the tweeters. The sound is much better than the factory speakers. No distortion at higher volumes versus stock. Highly recommend this upgrade. I can now hear the radio even on the freeway with all windows down! Just one more suggestion, stuffed the sound bar and front speaker enclosures with poly fill before installing the new speakers. This will make the bass sound better.
