New head unit on my E90
Hey guys,
So I just traded in my E92 328 (676 option) which I put in a double din pioneer head unit. My question is in my 07' E90 335i (677 option) will I be able to utilize the same dash kit and wiring harness? Thanks!

If thats the case I would either have to do what you said and just use 4 of the 7 speakers or I would have to run a new amp, bypass the OE amp all together and tap into the speaker wire coming out of the factory amp. Do you know of anyone who has done this? Ive been searching around but I see so much stuff on hifi and not logic 7 upgrade when it comes to new HU in conjunction with utilizing factory speakers.

Basicly you loose the amp.

So far dynavin is the only company that has made a device that converts the BMW optical signal to something the L7 amp can use. And I think it only works with there N6 Head Unit not sure you might check. ( or they may only sell it with the N6) and that option just came out. There is another company that makes a preamp that will decode the BMW optical signal but that is not what you want. The route to redoing a L7 system to aftermarket are well documented here. http://www.e90post.com/forums/showthread.php?t=641323 Op was asking about the Head Unit fitment ,but I don't think he was aware of the fiberoptic interface between the amp and Hu. For amp replacement The older solution is an MS-8 and some amps and speakers there is also the Helix 82dsp both are 8 channel amp/processors . I would go with the Helix as it gives you 50 watts per channel as opposed to 22 watts for the ms-8 and it's more tweekable. Last edited by ctuna; 11-18-2014 at 12:00 PM.. |

So how do you like your system? Did you use the alipine to power the speakers or are you running a 4/6 channel amp? Quote:
Where do I buy these harnesses?

FYI
This looks like a good replacment if you don't want huge power
http://www.e90post.com/forums/showth...ighlight=helix or you could add some amps for woofers and sub woofers on top. You have to PM Technic here. be sure to map out what you are going to do and read the threads on L7 systems. |

For now I have an xd600/6, morel hybrid ovation II's, and jehnert xe200. I also have 2 alpine type r's powered by an audioque 2200d My headunit has time alignment, crossover, and eq adjustments which are useful. I'm happy with it for now. I'm going to keep the headunit, door speakers, and underseats and replace everything else with different equipment. |

Nice!! I really want to get the xd600/6 and run the factory speakers for the time being. Once I get that all taken care of I will upgrade the speakers. Did you just unplug the center speaker? I want to use the xd600/6 to power the front door mids/tweeter, the rear door mids, and the rear deck mids/tweeters. I would be deleting the center and under seat subs. I will also be putting in one JL W3V3 in the trunk for the Lows. So in effect I would have 2 amps powering a 6.1 channel system. Should sound pretty good. Quote:
Okay gotcha, I will probably utilize the factory crossover/ speakers for the time being running one channel per door until I buy nicer 4" component speakers with better crossovers.

8 channels and dsp is why the Helix is attractive.

Also the power is more in line with the power ratings of the stock speakers. I haven't heard of many frying the speakers in even the HI FI with the jl 600/6 though. |

My head unit AVH - X8500BHS uses RCA preouts (front and rear) so I would only be able to use one of the preouts converted to AUX which would disable any fade feature I just question the design setup of that amp, it looks like it best used with a stock stereo (correct me if im wrong)

Well it would correct the eq on the base system
Well it would correct the eq on the base system
but it would also allow precise eq and time delay if you haven't already got it. The Jl is a perfectly good amp its what I have against in a Hi Fi system. A lot of people here are of the opinion that back speakers are useless. |
