Looks good, I got my F07 ( 530D SE GT ) with standard sound ( 4 x mids and 2 x subs ) be nice to upgrade to top Hifi tweeters in front door pillars and the mids in the doors and see how that rocks as the bass is good from under the seat just needs more clarity ,definition and height
has anyone done just that ? on F07 or F10 / F11 |

is there a schematic were to understand ohm values for different setup?
I have a european x3/f25 model with professional navigation so no clue what is the hifi setup. I know I have no tweeters but I bought cheap used top-hifi tweeter willing to add these to the existing mid/sub unit. Will I affect (lower) the impedance? Thanks |

if replacing audio base loudspeakers (single midange without tweeter) with hifi speakers (midrange PLUS tweeter) is there any problem for the audio amp to drive two speakers (less resistance value) instead of a single one?

No -- tweeters in this context don't significantly change the load presented to the amplifier.

By the way, great job and thanks for sharing. For the record, you *could* have contacted us for plug and play upgrades which sound EVEN better than the Harman Kardon speakers.

The iDrive unit can handle 2ohms according to BMW. Less than that and the unit will overheat. This has to be done the right way. |

This has to be done anyways for two reasons, impedance and to make the woofers sound the best with what you got. They should have their own amplifier channel so each can be tuned/crossovered more efficiently. There is no filter or crossover between the woofer and the mid with the iDrive system, so the sound is just split (highs/mids/lows) by each speaker own frequency response and that's it. |

oh no
thanks tech Manual says that it is compatible with 1 Series, 3 Series and X1 can't imagine why 5 series is not on the list http://www.focal.com/en/dedicated-dr...050750531.html may be first stage, cut woofer & install some compatible stuff like ifbmw-s ( rock & roll is not my cup of tea) then second stage amp for woofer ( any cheap & simple installed amp in the market recommended?)

That's your iDrive unit. There is no external OEM amp in your car.

Yes you have mentioned earlier
The idrive is stable at 2 ohm Am i do it the right way as follows: Front: 2 Tweeter + 2 mid speaker in parallel Rear: 2 woofer + 2 mid speaker in parallel |

You need to run new cables to the underseat woofers (thus separating the front from the woofers), that's the easiest and the right way.
