2011 E92 Base Stereo upgrade - need help
I have a 2011 E92 with base stereo - which really sucks (even compared to my previous BOSE factory stereo in my G37 coupe).
I was hoping to upgrade the sound while leaving the headunit stock (want to retain the steering wheel controls and blue tooth phone connection).
What would be the best route to go? I would prefer to keep it around $1,500, but willing to go higher if really needs to.
I also don't want to lose trunk space - maybe a small enclosure? or subs under the seats?
I'm not tech savvy to do the installation myself. Located in LA.
Any help is great. Thanks in advance.
