I was very disappointed with the staging of the Altima stock system. I had an 05 rental for a week and a half. I couldn't tell a distinct left/right in that car.

I was actually impressed with the volume and clarity of the stock system though. Quite a few of my CDs I was able to turn up all the way and I didn't get any distortion. I thought it was amazing that Pantera sounded crystal clear at full volume on a stock system.
