First Porsche to have HDSS-certified TBI Sound Tweeters
I recently got these super bad tweeters installed in my 2004 Cayenne S. I got two sets installed..two in the lower front, near the kick board and the top rear. The sound is crazy. Here's a link to the TBI Sound web site where my car is featured:http://www.tbisound.com/dsp_products_auto_installation.asp
