My 2006 Lexus GS-350 Luxury Sedan has a 14 Speaker/300 Watt Mark Levinson Premium Sound Audio System inside of it. And I listen to FM Radio, CD's and my i-Pod with it. I didn't have to do a thing to my Lexus.
Neither did the the 2000 Audi A4 that came before it.
The first serious car I bought back in the mid 1990's was a Honda Accord EX with Leather and Sunroof. Now, I did put a nice system inside of that one. It consisted of a high-end Alpine Radio CD Player with Changer Controls, a companion Alpine Trunk Mounted CD Changer. 700 Watts worth of Rockford-Fostgate Amplification in the trunk to drive an ADS Component Speaker System and Discretely Installed 10" Subwoofer.
