So I FINALLY was able to finish installing Bimmertech’s plug and play Amp in my ‘22 X4 that came in with standard hifi and not HK. I personally thought the standard hifi was average at best and wanted something better. I have to say after installing the new amp, it’s a 100% improvement. The sound is now clear and crisp, exponentially louder and the bass is booming. It truly is like being in a concert hall now where as the original standard hifi sounded flat and weak. The amp comes pre-tuned for your vehicle right out of the box, but also can be further tweaked easily right at home. I highly recommend this upgrade if you are on the fence about it. Beyond easy to install, and the sound difference is night and day! I feel like the X4 is now complete!

Awesome -
I have the HK sound system in our 2021 X3; would this improve the HK sound system??

Thanks for the review! This is likely my next mod. Love how easy the plug n play installation is.

I believe they have a separate amp for those that have HK and I think it would still be an improvement. I had HK in my previous X3 and this definitely sounds better.

Great to hear. I was on the fence about the HK anyway. Thanks for the update!

Just the amp and no subs?

Nothing but the amp. Talked with Bimmertech and they felt upgrading the amp alone would be a big enough improvement to start with and suggested I do that first before seeing if I still felt I needed to change out the speakers or subs. Honestly don’t think I will need to!

Just what I needed to hear -- er, read. Our X3 M40i can't be ordered with H/K, so seeking an aftermarket solution that's both effective and non-invasive. This fits the bill 100%!!

Can I ask how much the amp cost?

[Chief Orman]

Fantastic I have one in the box ready to install…

[bmwplow]

Thats awesome. Mine is stuck without HK too, so I will definitely be doing this upgrade.

sucks the price went up though

Did you have to buy the 75 dollar cable too?

Snagged it right before Christmas for $900 on a Christmas special they ran, but price has gone up since then.

[TC1856]

I was hoping a bit cheaper. I’m mostly sports talk radio. At $1k for the amp, I’m going to wait for car in March and see if I can deal with the base system.

Thanks for this. I think I'm going to do this too. How easy was the install? Can someone who is not A/V savvy handle this? Lol

Absolutely. Very easy to install. Truly plug and play! Took less than 30 min total.

Thanks for the review. I just ordered a X3 40M. I'm very interested in getting the amp and upgrading my sound system.

[Angelo_GraysonMiniBMW]

Thanks for the review and I will be ordering the amp once I get the production number for the m40i.

Nicee man. How much louder is it at 100% volume ? Not only does it sound flat too me,I feel like at full volume it’s not nearly loud enough. Maybe I’m going deaf lol

I spoke to BT and they said it’s 30% louder. Which wasn’t promising to me

I agree with you on the original sound being far too low. I literally had to turn it up so much just to feel even slightly satisfied and it still lacked. Once the Amp was in I had to turn EVERYTHING down! It has so much more volume and kick to it. Trust me, you wont be disappointed in that department.

I purchased a 2022 X3 with the HiFi system two weeks ago and installed the amp from BimmerTech three days ago. Very easy install. I am seriously impressed with the sound coming from the amplifier upgrade (for those of you wanting to know the cost please look at the Bimmertech site). It was an expensive purchase but well worth the cost in my opinion. I have had three BMWs over the past 20 years with the Harman Kardon upgrade, and have been generally happy with the sound. The BimmerTech amp upgrade (to me) sounds as good or better than what I heard in my cars with the Harmon Kardon equipped cars.
I purchased the Alpha One Speaker upgrade package as well. I am hoping to install the speakers this weekend and will provide an update when I do.

Looking forward to that review! I wasn't able to put HK on my build. I'm ordering the amp for sure, but curious to see if they speakers are worth it and how easy/hard the install is.

Upgrading speakers in my old cars (before my BMW days) was always a pain and left me with door rattles, broken door clips, general unhappiness.
