listening to music in the car

Sbrtoy, agree on all counts. My system exists no more (Tired of repeated radiator leaks and donated the car) but the amps and sub woofer box practically rotting in my garage. I let the expesive head unit and dsp processor and component speakers go with the car. Eq and time alignment is only for car!! That is the only way I can be on sweet spot in driver seat with close to flat sound!. I, too, would never think of using for my home system. But overall the $10-15 K spent over dvelopment cycle sure was fun. Cool factor was a bonus as friend brought friends to audition my system! My prelude was botched all over for the stereo, what with 14 + speakers, all thoes wires and dynamat. I would care for the stereo but not the engine maintanence of the car!! I would never do that to my Boxster S. Well I did install the stock DSP and Bose Subwoofer but it is all STOCK!!

Acura ELS sound system is VERY good. Especially with Apple Carplay using Plex app and highest quality source files synced to plex on the Iphone 6.  I would definitely recommend. 

Interesting post. Opinions all over the board, so here's mine:
No car stereo can compete on sound quality with a home system in a dedicated room, with room treatment, using a dedicated AC line. The noise floor in my room is around 35 dB. The average noise floor in a car (any car) being driven is up around 70 dB. You lose all dynamic range in a car, you lose any sense of a soundstage in a car, you are hearing all sorts of delayed reflections from all those hard, vertical surfaces causing temporal smearing in a car.
I'm a car enthusiast, and an audiophile. IMO the two don't mix well. When I'm driving I'm focused, usually well above the posted speed limit, and I'm having fun. I never even turn on any music on when I'm driving because some cars have such wonderful engine sounds (inline-6 BMWs, flat-plane crank Mustang Shelbys, Corvettes, exotics) that I much prefer listening to them.
My dedicated listening room is for just that. Listening. No TV, no games, just listening, and it sounds wonderful.
I guess my response would be that the OP is listening for certain aspects that his car system is able to provide.
They sure don't do it for me. 
Happy listening, to each his own.

I have a high end Burmeister sound system in my car for which I paid lots of extra money.   The truth is that I can only appreciate it when stopped for a light...otherwise, the tire, wind, and motor noise swamp any advantage.

I agree Stringreen  

Assuming one could listen for extended period of time at 90 DB, average background noise in a car is probably 40 to 75 DB.

So we arrive at a stunning dynamic range of 15 DB :-) and intelligibility masked by the combined noise of tires, engine and other vehicles in the traffic.
