If you haven't already the best thing you can do is have your door panels treated and maybe and floor if you're willing. The spray on stuff is more effective than Dynamat for door panels, but Dynamat will work well for the floor. Treating the car will smooth out the tonal balance and curb the slightly aggressive tweeters Focal uses. If you still have a problem with thinness, check out the Nakamichi head unit or look in to swapping your Soundstream amp for a McIntosh. McIntosh gear is warmer and fuller than most other brands. Good Luck

Firstly, I hope those word aren't an oxymoron. I've got all Focal drivers with a Soundstream amp. I bought an eclipse head unit and in-dash changer and hate the sound. Its not bad, but for as much as I spent, I'm not happy about it. It just sounds thin and unlifelike. The factory cd player through the spkr-line level adaptor didn't sound that much worse. If anyone has any experience with some head units in the car that really sound nice I'd be appreciative. The most I can do is exchange the Eclipse gear or try an sell it. Is Nakamichi about the only other one? And just how bad are the tuners at the expense of a good cd player. My home system is a fanfare tuner with all Van Alstine gear. I don't expect my car to sound that good, but at least musical. And I won't buy McIntosh, too expensive and ugly.
