I bought this JCW Clubman after my old Civic was totaled while I was working on a pretty nice install with three DLS amps and a miniDSP - frustratingly, never got to the finish line.
On this car, I'm just now about to replace the Entrynav1 (NBT) head unit with an Entrynav2 unit I just picked up and had programmed, to add a bigger screen, touchscreen, and wireless Android Auto with a non-MMI unit I just picked up - still to be installed (working on my R52 S at the moment).

Sadly, even though these awesome DLS amps for my Civic were compact amps, I'm not going to fit the three of them in my car without completely losing the lower storage area, which I don't want to do. I'm not going to be able to run my miniDSP unit, because my HK system has MOST optical running to the amp, and I am using a factory head unit.
I see there's replacement amp options out there in the $1300-$1400 range, and most "have" DSP, but it's not clear if those are just preset remote-loaded 'tunes', or if it's a proper DSP that allows tuning (via any means - app, laptop - any interface to adjust Xovers, EQ, timing, etc)

I have all the gear, great reference mic, headrest mounts, RTA (now laptop based), years of tuning experience... would be impossibly limiting and frustrating to have to be constrained to preset tunes. I'm an audiophile, I'll be swapping in and out different mids, tweeters, playing with A-pillar locations, etc.

On a related note, it would be a nice bonus to have a passive (RCA) output to add a separate sub amp here and there [on my own power wiring]. I'll be doing my best at some point to get those underseat midbass drivers working as best I can, but a real sub is something else entirely.

Are there any F56 HK replacement amps out there that have a DSP I can tune myself?

Thanks in advance!

 

Bump - even if you can list ANY replacement amp for these - I'm glad to take the research from there.

F54 and F56 likely have the same upgrade options.
I'll collect and consider any and all "OEM replacement" style amps (to fit where the factory HK amp lives).
You may just list one that I'm not aware of, and that would be GREAT.

The ones I'm seeing are:

• BimmerTech Alpha One, but I'm skeptical that I can do my own DSP tuning from what I'm seeiing. Seems to be "we'll pre-load a tune for you".
• Match Up 7 BMW

For other options all I see is this:

• Audison makes a MOST adapter, but that's $600 plus. Then I could use my miniDSP and find an amp that fits in that side panel, but that will greatly complicate the install and possibly lose my hatch floor storage.
• MoBridge also makes a MOST adapter, but that also is $600

Thanks in advance for any other options, or comments on these.

 

I’m not an expert, but I would think the MOST ring is going to be your hindrance. Any inexpensive amp likely won’t support it. I believe the audio signals travel across a dedicated harness, and would be easy signals to intercept with an aftermarket setup, but you’ll probably have to piggy back the HK amp and leave it plugged into the MOST ring.

 

I did try to use AI for this - Gemini is on my Chromebook, and it actually brought front and center my one concern that I won't be able to do my own tuning on the Bimmer Tech amp:

Both I believe also have an RCA output to add a dedicated subwoofer amplifier for a real subwoofer, so that's a wash.

Pretty interesting that AI brought up the "tuning philosophy" here without my prompting for it, as a difference between the two.
I'll dig in a little more, but I also did this with Copilot the other day and it told me the Match Up7BMW had less power on the main channels and more power on the midbass channels, while this result is telling me they have the same power on the midbass channels.
Copilot also said that the Alpha 1 does have software for DIY tuning - I even followed up with a prompt to tell me more and it seemed to confirm it does allow it.
So I still do have to dig in to confirm the information here, but I feel like I'm leaning more towards the .Match Up 7BMW at this point anyway.

I'm also hearing good things about the Match Up7 midbass drivers for underseat - so maybe I'll pair those up. Seems like the for-sure-DIY-tuneable amp plus two midbass here might be in the same price ballpark as just the Alpha 1 where I'm apparently paying for 10 channels although I only need 7 and it's not clear what benefits there are to going that route.
