Aftermarket X7 Specific 676 Hifi Upgrade
I've seen some comparisons done for other models, however not seeing anything specific to x7s (apologies if there is another thread already and just not seeing it).
Has anyone out here actually heard and/or have an opinion on upgrading the stock Hifi (676A) to Bimmertech's Alpha One amp/speakers (or another similar non-OEM upgrade) and where this lands quality wise vs. OEM options which are basically non-existent this year? What I'm really hoping someone can provide is a baseline opinion as to where this aftermarket system would fall if built on the 10 speaker Hifi setup (eg. equal to / better than the 688HK even with less speakers, however not as good as B&W, etc.). Thanks in advance for the perspectives. Last edited by Lando X; 01-15-2022 at 05:14 PM.. |

Put differently, does the 676 hifi upgraded to full alpha one system actually sound better than a straight oem 688 hk system without any upgrades? Realize no one may actually have a data point on this particular head to head comparison but very interested if someone does. |

What you really need is someone who tested them head to head with good analytical equipment and then created a waterfall graph to show the differences. Since that likely doesn't exist you've got to trust that it absolutely must be an improvement over the shockingly abysmal sound quality of the OEM system.

I've heard the OEM Hifi and I'm sure the full upgrade will significantly improve the quality, just hoping it gets me in the ballpark of the oem HK even with fewer speakers. Totally hear you on sounding better being subjective and if I strictly look at specs, I'm cautiously optimistic that the hifi amp/speaker upgrade could theoretically sound better or at least put it in line with the oem hk.

Not sure if you're buying or leasing, but if I was keeping the vehicle I'd be more inclined to go to a very reputable car audio shop and have them custom install a bespoke system using Focal's.
They make speakers that should fit all the factory locations as shown here: https://www.crutchfield.com/g_400/Al...38;clearsloc=y Replacing the amplifies may be a bit trickier but I know there's people on the forums that have done so. You might have better luck looking in the Gxx 5-Series, X5, and X3 forums since there are many more of those on the road. Best of luck though! Please report back once you get it all figured out. 🤜🤛

Going to be visiting a well known local installer in comings weeks to get his take. I have concluded not attempting by myself unless new information comes to light between now and then. |

Quick update.
I talked with a well known local installer and he has no concerns about doing the installation of the speakers or the amp. He indicated he was aware extra panels do need to come off in the trunk and it's definitely not as easy of an install in an X7. He also said he felt it was a considerable improvement versus the Hifi or the HK upgrade and was worth it if willing to drop the money (unfortunately, the cost of this stuff has gone up due to the semiconductor shortage). I'll let everyone know how is goes! I pulled the trigger but unfortunately couldn't get on his schedule until early June. |

It's definitely more money than what the HK would have cost as an add-on (-650-850) if it had been available at the time so I'm going in with pretty high expectations. Have been able to pin down a lot of data points that the quality is something between hk and bw, even with the fewer number of speakers. My understanding is the amp that comes with the hk isn't anything to write home about. Guess I'll know soon enough, crossing my fingers! |
