Underseat subwoofer spec?
I've done some searching on the forum and the internet and have been unable to confirm the speaker ohm value.
Having taken it out, hoping that it would be on it, annoyingly its not. However the process to replace is very easy Has anybody done this or able to confirm whether it is 2 or 4? My system is standard, no HK. Last edited by Mushy007; 10-08-2018 at 07:21 AM.. |

Would like to know as well.
My F48 20D, none HK sounds like a bag of balls, I'm no audiophile but do appreciate good sound. Previous cars had HK or the equivalate and the F48, given it's internal space sounds crap. Am looking at a couple of options but want to keep it OEM. |

Bavsound reports that their replacement sub speakers are 2 ohm. Since they are available separately from their full speaker package, I would assume that they are the same rating as the OEM ones.

No OEM amp woofers = 4ohms
HiFi woofers = 2ohms HK woofers = 4ohms Quote:

Anyone got thoughts on these for the front and rear doors, I have the base stereo and these look a good option?

Received my Eton speakers for the front today, fitted them and did a few videos, to show the difference.
Base stereo:- Left - Eton vs Right BMW:- Both fronts with Eton units:- Off to order another set for the rears and the subs All plug & play. |

Sorry to post in an old thread, but I'm looking to upgrade my speakers as well so this seems very promising!
My car has the Hifi system but I think it sounds pretty bad to be honest. Makes me wonder how awful the standard sound must be ... I was wondering if Etons would be compatible with my car as the impedance of the subwoofers and possibly the door speakers will be different. Edit: According to the PDF on their website, it should be fine. Important to note however: For the Hifi system (SA676): the optionally available B100 XHP midrange crossovers are NOT required, as appropriate active filtering is already carried out in the original BMW amplifier For the standard audio system: Please note that an additional BMW B100 XHP high-pass crossover must be installed when operating the midrange speakers on the original wiring harness using the original head unit (without amplifier). This is not included in the package and must always be purchased separately. Also, as of 09/2020 there is a revision (improved) B100 XHP due to problems (crackling noise at high volume) with the original ones. You can find all the info on this page. So it seems like I'm installing some B100 XW's, without the high-pass crossover. If I like the fronts, I'll do the rears too Last edited by Humpus; 04-14-2021 at 08:15 AM.. |

Understand that a HiFi(676) system is not an HK(674) or a HK(688) system.

Mini F56 uses code HK 674 and in that case mentions the source I quoted above that the woofers are 2-ohm. You say that on F48 Base = 4ohm woofers HiFi = 2 ohm woofers HK(674) = 4 ohm woofers Bimmertech says Base = 4 ohm HiFi = Doesn’t mention HiFi for F56 platform HK(674) = 2 ohm In other words your claim contradicts them. Also you claim that HK amp (674) is stable at 2 ohms which makes me think that the HK system woofers in a F56-based car like the F48 is 2-ohm not 4-ohm. But then again I don’t have the hardware and I cannot measure it so I have to rely on information written by others like Bimmertech and you. That is also why I am asking where you got that information from, did you measure it yourself or did you read it at other place as well? Quote to the relevant parts Quote:
