My friend showed me his car (2005 Nissan Altima) and showed off his sound system. He's got the "stock" 8.1 Bose system with an aftermarket Sony DVD player. He played a music DVD and I fell in love. The sound was so vibrant, rich, and it was just hypnotic/ecstatic to sit there and listen to the tracks he played.
The sound system in a WRX (2005 wagon here) comes nowhere close to it. I almost never listen to anything in my car because the system simply sucks.
Is there any aftermarket system that can match the Bose?
