I had reached what I would consider to be about as good as it gets in car audio. I was running a Macintosh 6 ch amp & CDP, Dynaudio clone mids and tweeters custom x-overs, and door enclosures, MB Quart Subs. It took a lot BS dealing with car audio morons. My biggest problem's were sound stage, image, depth, instrument separation, bass integrating. The speakers were located by my feet under the dash so the sound stage was low custom enclosures angling the speakers and adding a second set of tweeters on the pillars helped a lot with this. Imaging is a problem in a car considering your not sitting in the center. I was able to get some depth and separation but nothing like at home. I do think the sound wrapped around me better and the bass was more solid. I think I prefer sitting close in my home system because of this. I feel my car system held it's own with some home systems but not with properly set up ones, too many things were lacking. I sold my car system to get into home audio, I wish I would have known then what I know now. It would have saved a lot of money and headaches!
