2023 X5 (G05) with Harman (688A), MATCH UP 10DSP profiles

03-17-2026

Hi,

I am currently upgrading the audio in my BMW X7 G07 with the factory Harman Kardon (RAM) system. I just installed the Match UP 10DSP amplifier.

I kept all the factory HK mids and tweeters in the doors, but I upgraded the under-seat subwoofers to the Helix Ci5.

I saw your posts and screenshots of your custom .afpx tune (with time correction, customized EQ, and sub reverse). It looks exactly like what I need! Would you be so kind and share your tuning file with me?

It would be a huge help to have a safe, high-quality baseline, especially to get the best kick out of those Helix subs without risking the factory HK speakers.

Thanks a lot in advance!

Good Morning Psaav, I’m new to 10dsp and currently have it installed on my X7 HK with speaker upgrades and Bavsound Ghost v3 4ohms, wanted to ask if you would be able to share your tune for me to checkout? I appreciate your help!

I received some requests for DSP settings. Let me post them here.

Input routing

Input EQ

Fronts, Rears, Surrounds and the Center are getting different factory signal from the Harman system.
They also have built in crossovers (signal drop) to protect the factory speakers.

You can do several things:
- 1: leave the inputs as is
- 2: EQ them to be similar/same
- 3: make a flat-ish signal -> !!! after which you will have to watch out for crossovers since you are removing the factory protection !!!

I picked route No. 2.
I EQd the input signals, and got the Fronts, Rears, Surrounds, Center to be the same... more or less...

Flat-is signal

With the Match UP DSP, you can combine inputs signals to create a Flat-ish signal.
Front + Woofer can be combined to get a combined signal.

It won't actually be flat, as the Woofer signal has a rising signal from 160Hz down to 32Hz, and below it starts dropping.

Notes:
- combine Front L + Woofer L -> not perfect, but goo enough
- EQing your inputs, then combine them ->you can get a nicer looking signal
- if you want a close to flat signal: EQ your Inputs + adjust Woofer level + combining it with the Front

Input EQs
If anyone is interested, I can post my EQ settings for the Inputs.
Let me know.

Important
Logic 7 Enabled vs. Logic 7 Disabled have very different signals.
I have Logic 7 off.

Time Alignment

This one is critical, as bad time alignment will mess things up.

Notes:
- factory inputs have built-in delays
- factory input delays depend on the Logic7 setting (ON/OFF)
- physical distances add on top of all this

MY setting below is for 688 option, iDrive7, Logic7 OFF.
The Front, Rear, Surround, Center delays should work well.

Unfortunately the Bass part is a bit tricky... so my Woofer TA settings (channel I and J) probably will not work for you.

In case of the Woofers, note the 1.83 ms time difference between the two.
This is important to get the 2 in time, measured from the driver's seat.

Then, You can group the Woofers together, and start moving them relative to all other speakers.
As you move them together (keeping the 1.83ms between the two), but move them relative to the other speakers, you should notice a difference. If will either get better, or worse.
Move them by 0.1-0.2ms... you can go 2ms either way (up or down).

If you have a Mic, and use Pink Noise, you can actually see what is happening.
And you need to find a spot where they sound the best (getting their phase to match the rest of the system).

The Woofers are a bit challenging. But... moving them can get you close...

One last piece of the puzzle: Phase
This one is tricky, because with all the speakers in the car/the passive crossovers, speaker phases are not perfect.

I measured phase. And adding a 2nd order All-Pass filter to the Front L speaker, fixes the Front stage.
Give it a try.

Try the following on the Front L speaker:
- All-Pass / 2nd order
- @480Hz / Q=2

Of course, these are just Settings/numbers.
Without context, they may not mean much.

Feel free to ask.

The AF default file only routes the inputs to the outputs.
Nothing else is included in that.

All settings need to be done after that.

AF has a page called "Sound Upgrade Finder". It is supposed to help you find the possible upgrades, they designed for your system.
https://www.audiotec-fischer.de/en/soundupgrade

For my car's system, an additional MEC Analog In card was needed. That is where the Center channel was connected to:
https://www.audiotec-fischer.de/en/match/accessories/mec-analog-in

And the factory AF harness has the connections prepared for it:

When did you get the Match UP 10? You can check with them, what they sent you and what they have specifically for your car + sound system.

Hey guys,

I could really use your help. I have a BMW X5 G05 with a MATCH UP 10DSP and HELIX speakers, and honestly, it sounds pretty bad. I had it tuned by a shop, but the bass just booms and overall it simply doesn’t sound good.

My setup in case it helps:

- BMW X5 G05, originally Harman Kardon
- MATCH UP 10DSP
- Front: HELIX Ci7 midrange + HELIX i5 tweeter (passive together, no active front system)
- Center: HELIX i7 mid/tweeter
- Underseat woofers: HELIX i5
- Rear: HELIX i3

Does anyone maybe have a DSP file or a sound setup for something like this lying around? Or does anyone here have something similar installed and can tell me how they tuned it? I’d also appreciate screenshots of crossover frequencies, time alignment, and levels.

Thanks in advance!

Wow. Great setup. I can try to help you.
Do you have the settings file? Can you send it over?
I can look at it, and give you some pointers.
Send me a PM.

Hey, thanks a lot for offering your help, I really appreciate it!
My account is still pretty new, so I’m not able to send private messages yet. I’ll send you a PM as soon as they get unlocked.
Thanks again!
