I need some advice on High End Car Audio...


I was asked by a friend to figure out what would be a good system to replace the awful standard BMW sound in an older X5. I live in NYC and don't drive anymore, but I remember Wes Phillips had a column a few years back in Stereophile that focused on High End Car audio. Does anyone have any ideas, links or reliable car audio dealers. Most of them sort of remind me of a sale Saturday at J&R Music World...

These guy did the radar system in my car and did a great job. There a little pricey, but they do a pro. job.
Find a high end shop in your area that carries the Focal line, Focal makes some really nice component sets for automotive use.
You will need to find a great dealer, who has a real understanding of high-end audio. Cars can sound really, really good, but it is very rare to find a car audio dealer that has a clue whatsoever. Most car audio shop owners have never heard a real high-end stereo, and are in the business of making cars boom and bump.

My best advice is that the installation quality is by far the the most important aspect of any car stereo, so make sure you find someone who knows how to make speaker cabinets out of car doors. My best recommendation, is to not commit to a dealer before hearing one of their car installations, and confirming the "good sound" to them, is anything like "good sound" to you.

I went through 3 car dealers, all of whom promised the world, and delivered extremely sub par, bordering on painful installations. I finally found someone on a car audio forum who really knew what he was doing, and was able to build a car audio system that even an audiophile can enjoy.
I spent years chasing this. The biggest thing I learned is that you can't go in to a store, listen to speakers in a board, and have a good idea of what they will sound like in your car. The car acoustics are so awful, anything that sounds good in a store sound room will sound awful in a car. Good car speakers are designed for the car acoustics and will sound thin and screachy in a regular room. Definitely listen to systems that the shop has installed in cars. Also, make sure they understand the kind of sound you want. Most people want tinkle and boom sound. I was in a local shop, and the owner demonstrated his show car system for me. I told him I thought there was too much bass and highs, and the sound was unnatural overall. He said he understood what I meant, twiddled a few switches and knobs, and played the best car system I have ever heard, better than many home systems. If they answer questions by saying "This si what we do, we are the best, leave it with us, you won't have any regerets..." without some indication that they know what you want, just walk away. (This applies to many things, and is why I built my own deck - too many contractors promising much, with no evidence to back it up).
I had two 3 Series before and I installed Focal speakers in the cars. Go for their top models. And I am using Brax power amps for years. Have yet to find anything better. McIintosh do have car power amps. I only like their head units. The problem is the source. It is going to be hard to replace the head unit unless you want to forgo all the functions in your steering wheel. But there are adapters available whereby you can install a better quality head unit and still have the functions on the steering wheel intact. Funny thing is most of the good head-units are Japanese. Most of the better sounding amps are American. Go figure?!
