I am looking to upgrade the audio for my 2010 WRX Sedan looking for some suggestions. I would like to have Sirius Satellite in my car but Subaru wants $509 to install the antenna and transmitter behind the stock head unit and I find this ridiculous. The stock head unit and speakers are horrible in my opinion. (With the volume completely turned up I can still have a phone conversation because the output is so low).
I would like to either upgrade the speakers and leave the stock head unit in the car (also having Sirius Satellite installed) or completely replace stock head unit and speakers.
