If you have never heard a Mark Levinson sound system in a vehicle you are in for a treat!!!!! It's AWESOME! My wife's 06 GS 430 has 14 speakers in that little thing and you have got to hear it to believe it! Superb ultra-tight bass from everywhere it seems, surround sound, 330 watts, etc. Levinson is the same guy who designs home systems in the $30K to $40K range.......

) Take a listen if you haven't heard. Had the same system in our LS 430 but didn't seem to sound quite as good, although it was still pretty awesome.
