As for aftermarket stereo recommendations, that's up to you. You can visit your local bestbuy & get an in person & hands on testing.
Can also look at your FB market place. Type in double din stereos 6.9in 7in
My aftermarket stereo is a kenwood DDX773BH from a pawnshop.
Installed Rockford Fosgate 6.5 fronts & & 6x9 rears with Rockford Fosgate amp.
If you decide to upgrade the speakers. Don't break, throw away or destroy the speaker brackets you will need them.
I upgraded the speakers to pioneer few years ago. Sounds much better. Finally getting around to changing out the head unit. Probably pick up a subwoofer while I’m installing the new one.
I'm sure the audio quality, had it gotten that far, would have been pretty terrible too.Much better! That piece of crap I ordered from Amazon actually started to glitch and freeze up before I got a chance to get it out.
