Well i am going to do a Stereo upgrade on me ES i wanted the better stereo in the SE but not willing to buy all the other stuff that went with the SE to get it.
The plan is a clean stereo system. Speakers and amp will be infinity (links below)
I have not figured out how well the speakers are going to fit and i don't know where i am going to put the amp yet. I am still working on looking for a deck to run it all.
I am thinking about a pioneer appradio 2 so i can run it with my android phone. I saw the double din radio install and i think that is about the only way to go at it.
