My new amplifier upgrade

[c watson]

I’m glad after all these years someone finally took the initiative. Thank you GreyM340i

I purchased a match 7 dsp amp for my 2022 X5 and was sent an upgraded match 8 dsp amp. I’m not exactly sure if there more power in the 8 vs the 7, but lemme tell you this amp kicks a$$!! What an upgrade to my X5 hi-fi. It was $1350 well spent from Bimmertech.


Op, did yours come with a usb cable that connects to the amp? You can go to the audiotec fisher de site and look at the drop-down box for “tools” and download the correct adjusting tool. This is an EQ and I would recommend adjusting it little by little at a time. This is what all the X5 guys on bimmerpost said. The adjustments really do make a big difference. This amp peaks at 1150 watts and 650 watts rms.

Hey everyone! Just wanted to share my experience with upgrading my audio in my M3. The original system was a Hi-Fi system however the previous owner upgraded the speakers to BavSound speakers and a older Dynavin double din head unit. After receiving the car I changed the head unit out to a just released Sony XAV-AX6000 unit and even found a great deal on a now discontinued BavSound 10” powered subwoofer that mounts to the rear deck.

Well even though it is a way better experience the sound wasn't amazing and the power for the interior speakers was lacking. I kept trying to read about people upgrading the factory amp to a JL audio or AudioControl amp however I didn't want to cut any of the factory wires to make that work. And not many posts with upgrading the Hi-Fi system most were with the HK. Then I reached out to Audiotec Fischer and asked if they had any plug & play amplifier upgrades for the older E46 platform that uses the Hi-Fi 676 option. Well they forwarded my email to the USA side of their business and it said that the Match UP7BMW amplifier would work without any issues. It’s expensive at $1100 however I used to work at a dealer and a friend that works there got me a better price. I took the chance and today after installing it and uploading a pre-made sound setup file this thing is amazing. The power is unbelievable for such a small digital amp. I will need to learn more about tuning it however I might just pay to have it done next year. Hope this helps someone in my situation.
