Per the Lexus brochure: standard stereo system is 170 watts, add the 12 disc-CD player and system is increased to 210 watts. Nakamichi is rated at 280 watts "of natural sound and incorporates thoroughly reduced distortion and extremely wide frequency response from upgraded electronics and speakers" As far as I know, nothing is common between the systems except the CD player.
