I just completed my installation in my Boxster S with CDR-220 and DSP unit. Installation was relatively smooth. Results are great, no alternator whine or volume issues. I ended up adding about 18" extension to the ISO plug in order to have enough to feed down from the head unit and to have sufficient service loop to run both units outside their normal mounting position.

Only problem I had was the Empeg sleeve didn't want to go in, it was hanging up on some plastic nubs inside the mounting location. A little friendly persuasion didn't get it to go in, so I filed down the nubs just a little and then it went in. After the first time, it now goes in smoothly.
