The best description would be that it added more punch, though it seems to have lost some clarity. I did try changing some of the filterbanks, but with 55 of them and not knowing what they do, it was a crap shoot. I'm no audiophile, but do like my music to sound good. The same dsp is used in the e85, e86 and e83, so I'd assume the sound engineers at bmw used the 55 filterbanks to match the acoustics for each car. They must have put a junior engineer on the coupe LOL. There are a few loudness controls that are different in the coding as well.

I don't know how this correlates to our cars, but I've found some posts describing power amp/speaker replacement in e46
And these, which describe bypassing DSP http://www.xoutpost.com/bmw-sav-foru...fermarket.html http://bimmer.roadfly.com/5series/me...w51/33631.html http://www.m5board.com/vbulletin/blo...tallation.html I haven't fully digested the info in these threads yet. Anyone have any thoughts? The one installer I spoke with discouraged me from rip/replace, and said amp/speaker replace while keeping the head unit would be difficult. I'll call some more installers. I'm hoping I can get this to work. Who knows, maybe the Bavsound speakers plus a new subwoofer will get me there, but I have a feeling I'd be better off getting the first option to work. |

Why don't you, since you are in the bay area, swing by and hear my system with the Bavsound upgrade? That way you will be able to directly hear the improvement level and see if that is acceptable or not?

I was thinking of doing an AudioControl DQL-8 ........ 8 amp level channel inputs........ do the front 6 channels and the subs ....... it will EQ flat and convert to line level..... then add an outboard amp for the fronts and subs ....... you can still allow the rears to be handled by the factory amp if you want them. Replace the front mids and tweets with the 4" Focal set and the subs with the 6.5 JL 6W3v3 in the factory location........... you retain the stock look and DSP Nav screen capability. |

Would you use a 6-channel amp for the 6 front speakers? Then a 2 channel amp for the 2 subs? Sorry, I know a lot about home audio, but nothing about car audio. Last edited by funkle; 04-17-2014 at 08:01 PM.. |

One of the things I like about car audio is how immersive & visceral it is. You will probably never get the soundstage & nuance of a home system, but it is made up for in impact & sound pressure, which can be very involving in a kind of way that my "desk-fi" home system can't. I have a feeling the stock amp will never do this. |

Aw man, did you guys meet up already? I just got my M Coupe a week ago and noticed that the sound system is the pits compared to my 2.5i. I was thinking that maybe I had a subwoofer blown or something but I listened closely and they're just really poorly tuned. What the heck!!??

Yes, I really can't believe BMW would spec such a poor sound system. In comparison, my base '04 Passat GL, which is only 2 way I believe, sounds very listenable. Something has to be done. |

I'm actually starting to lean towards doing an aftermarket head like this Alpine It has bluetooth, iPhone & Siri integration. You can set the color to BMW amber, and even control it from the steering wheel. It will be a lot less than adding the amp interface and Media bridge. Probably will function lot better. The only real downside I can see is the looks of the thing. I'm also unsure how you could assess the car computer functions without the stock deck.

I have that head unit in my Porsche running the JL amp and Focal speakers. Really like all the features and smooth integration. You will be happy with that one...

I think it will do everything you want. Sum the front 6 speaker level outputs into a full range R&L front channel line level outputs, a rear channel full range line level output, and a stereo sub line level output. Full crossover network capability, EQ and time alignment with a 31-band parametric equalizer on each channel. It's all configurable and controllable from a laptop. I think this would be fantastic for our cars. Allows you to keep the integration with the NAV screen and also allows for additional inputs including Bluetooth. John |

An interesting thread on car audio. The poster is basically saying that the sound deadening is the key factor in the whole thing.

I was able to do the reprogramming and get the E85 settings into my M Coupe. It sounds MUCH better now. I will write up a thread on how to do it.
