Has anyone, like me, regretted not getting the HK and retrofitted it? I know some have replaced their OEM HK with an aftermarket, so I may be able to pick up the components for it, but are there model year changes from 02-05 that would keep it from being installed? Do you need different door panels? and trim surrounds? Any info would be helpful, thanks!

There is a Retro Fit Kit for the HK system. Not sure if its available in the US or not.


One thing I am sure of though, it's probably not worth the $1300 price tag.

If you dont choose HK when ordering your car you may as well go after market. For $1300 you could get a pretty nice setup.

Here is a link to the kit.
