I agree AK, the Stock Bose sound is excellent considering the it was designed in 91. However I think these other chaps might be looking for some BIG sound. And we know loud music for extended periods of time can damage hearing, lol, but serious this is true. I had a state of the art stereo in my last car, over 5K spent, but as I have increased in age the OEM stuff is perfectly sufficient. For example my 2000 Infinity OEM Bose stereo is awesome, and is more than sufficient and as time goes on the OEM equipment will even get better, no kidding.
