i'm guessing most ppl who cares to listen to the stereo while driving installed an aftermarket stereo, right? so my question is does the stereo remote controls still work w/ the aftermarket stereo?

 

For the controls to work i believe you need this!!

 

Or you can do the DJ Qube controls as well, they are great.

You don't necessarily need an aftermarket headunit, you can put an amp on the stock one and get some new door speakers and install rears in the lucid panels or get some s-pods.
