Honestly, guys, the most bang for your buck route to get better audio from the HK system, is by doing the BavSound Stage 1 for the speakers, doing an underseat replacement of the mid-woofers (either Bavsound, Jehnert, or Gladen, all of which are relatively plug and play) and doing the MusiccarNW add-a-sub, which adds a 10" sub to the trunk and depending on the options you choose, uses the HK amp outs to send a signal to an amp which can power your sub, and if you choose this option, power the mid-woofers under the seat.

I'm no audiophile, but I have done personal custom installs on cars I have owned, including very high-end bi-amping mids and tweeters and fiddling with DSPs to create the perfect sound stage. By doing all the above (what I said in the long paragraph with the BavSound speakers and such), you get a very nice sounding system, and I don't think you are going to get anything better without spending lots of time and money, and definitely not a very good return on your dollar (in other words, very little bang for your buck) You can certainly spend another 5-10k on a setup that Nelson from Bimmertech linked to in another post, but again, unless you have very finely tuned ears, you won't notice a difference between what I did, and what that setup in the linked post has.

As an aside, thanks for the info regarding the second option in the original post, I didn't know you could code it to believe it is a hifi system vs an HK system. Makes sense, though. In fact, the original post has a lot of good info, thanks for putting it together.

Also, here's a link to my MusicCarNW Add-A-Sub install, contains some info that people might find useful.
Dave - your post was one of great interest in my research. Thanks for the kind words - putting this together was fun. And your point about bang for the buck is exactly what I am weighing - given that I am at 80ish percent of damn good how much am I willing to spend in pursuit of that last 10-20 percent. Am I willing to give up trunk space to get it? Etc.

I had one question but since it was an old thread I didn't ask it - I was dying to ask. Now I will! Why didn't you/musicarnw pick off the underseat sub signal straight from the amp instead of wiring from the underseat subs back to the trunk and from the trunk back to the subs?
