Gotta love our dollar.
Yes, I am not new to the audio game, but not a hardcore audiophile by any means. I have always built and installed my own systems; nothing crazy, but better than stock. Built a killer center console/sub enclosure for my Bronco back in the day.You see knowledgeable enough so I have faith in your decisions. Subs add a great depth to lows and mids. If you haven't yet, look into component speakers, I thought coaxial were good enough, and then I tried component with an external crossover and given the choice, I don't plan on going back.
I just put some new mid's in the front doors, and then the rear 6x9's. The stock tweeters are now on my hit list as the one's I got with the mids were damaged and didn't get installed.
