Choosing an amplifier and speakers for the BMW G30.

B13ACC · 01-01-2025, 04:36 PM

Hello,
I need your help:
I have a BMW 5 series, year 2023, with sound option 676. I changed the front speakers with FOCAL K2 100ke, and the subwoofers under the seats with Match MW 8BMW-D. I don't know which speakers to choose for the rear speakers, because the ones from Focal K 2 don't fit, because of the crossover. I also don't know which amplifier with DSP to choose, having a choice, at approximately the same price, between Match UP8BMW and Audison Forza AF C8.14bit. From your experience, which do you think is better?
Thank you.

Hello,

Before changing rear speakers, get a good DSP amp like the Helix UP10BMW

With the speakers you chose for the front, you will get a huge improvement vs today.

And - to be honest, I would rather update the center speaker to Focal than spending time on rear speakers - most people have the ears direction forward, so sound should come from there...

Next, I would have recommended to get the Helix i5-200 with BMW spacers for under seat. That is, if not the best, then one of the best USW for BMW at the moment.

Hi,

I have the same speakers in the front + I added a centre speaker (Focal Inside). For the rears I would recommedn either Focal Inside or Steg (italian hifi speakers). These are, however, only a nice to have addition to the fronts. If you get over your budget, I would forget about the rears. I am using Match UP8DSP and I am very happy with it. Just one remark - proper DSP setup is perhaps more important than the brand of the amp. If not done right, it damages the soundstage.
