I upgraded all my speakers (4 total, 2 on driver/passenger side door, 2 rear deck). For the front speakers, I used Kenwood KFC-C6896PS's for the front and Kenwood KFC-6966S's for the rear.
For the sub, I positioned it in my trunk. I was able to get an audio signal by tapping into the rear deck speakers and connecting them to a Kicker 46KISLOC2 line output converter for RCA, which is convenient because it also comes with a REM output.
All said and done, music sounds amazing and I'm very happy with the results. I am by no means a professional, but I hope this helps anyone else looking to do some upgrades!
