Hi all - great to see all the fruitful enthusiastic discussion!

I recently installed the same amp in my F87 and G05. Made a world of difference. In my F87 I took the next step of upgrading the fronts with Eton.

Has anyone done any running with these cars that they can share? I basically just adjusted the various gain levels by ear but assume there's still some untapped potential!

I thought the Match UP BMW amps used were PnP, powered through the factory harness eliminating the need to run separate power or ground wires?
Or, did you purchase a Match UP amp that was NOT a Match up BMW?

How would I find out what radio system I have? My car is a 2021 M340i. I do not have the tweeters in the doors.

Prices seem to have gone up significantly.

Do you happen to still have your tune for the Hifi without the add on sub? Just got my 8DSP and the sound isn't quite right in my G20 LCI.

I sure do. Send me a PM with your email address and I’ll send it to you

I was pleasantly surprised in the under seat subs and honestly, could have probably been satisfied, but once you have had a big sub in your car there's no going back.

It really doesn't add a ton on top of the under seat subs but it does add that lowest note, impact and the happiness that big sound wave adds to the overall experience.

Planning to install a similar 10" low profile sub from Kicker ( 51PTRTP10 ) into the space where a spare would go in my X7. Planning to use under-seat woofers for 80hz and up and let the sub play the lows. My question is how high can the under-seat woofers play? Can they fill 500hz frequencies? Higher? Lower? Also looking to swap the Base HIFI speakers out but cannot decide whether to go with Alpha one replacements or if just used HK (Premium Hifi) speakers would be enough of a difference. HK in my 650i GC got real loud with factory amp. Kept up with a 15" sub pushing 800w rms

I just got myself the Match Up 8DSP for my BMW G20 330e year 2023. Overall, it sounds better than the HiFi stock but still tinkering. My speakers are B&W and the 2 subs is stock.

crpediem_2 could you please share to me the audio file without add-on subs?

Where did you plug all this in, is it at the right side of the boot space? All the videos show in under the boot floor which is where the 330e battery is.

If you’re facing the trunk, I installed it on the left side behind the storage tray. When you remove the trunk lining and the tray, there’s an open spot that you can screw the amp into. It’s right next to the Bmw amplifier.

I’m playing my under seat subs to 150hz. I don’t have a mic so I don’t know if they will play up to 500hz. Now I’m curious though, I’ll play with the software to see how the sound changes if I raise the cutoff.

Hello. Just got the 8 Dsp. Will that tune work on a 2018 540 with HIfi and the Match up 8dsp? If so could you send it to me? TIA

I just added my amp and sub. Used the line out from dsp. Want to make sure I have settings correct. In my IO tab under Main to virtual routing, I have "pass through 1" as Virtual I listed. Cannot change this. In the virtual to output tab, I can change "pass through 1" to "Line out 1". Lastly my Outputs section has Line out 1 (SubRC) listed. Curious if I have this correct.

Also, since dsp is handling crossover, do I need to set it up on amp or just gain?

[crpediem_2]

I do not use the virtual sound processing as I like the way the non virtual sounds. Here's a pic of my output settings and Line out. If you set up the crossover in the software you do not need to set it on the amp.

For the gain on the amp I would set it somewhere between 1/2- 3/4. This will give you more flexibility when adjusting gain in the software.
