BimmerTech Amplifier Upgrade review

Hi all,

Just wanted to share my experience about the amp upgrade from BimmerTech.

TL;DR - Service was great, the improvement on my H/K system is tremendous, installation took like 10 minutes max.

So after ordering my i3s and speccing up to the roof with H/K audio included I was quite extatic to pick it up from the dealer, however at the point where I have picked it up I found it severly lacking...

Severly lacking from the audio department. Thought to myself: "You have bought H/K option and it still sounds like this? You should have bought an JBL BT speaker instead"

Hugely concerned and disappointed in the disservice done at H/K by BMW I started looking for options, and there it was! The amp upgrade. Given it was costy, but I was more than willing to risk it just to "fix the issue".

After the order got shipped I got a call from BimmerTech with an ask "Hey, were you able to proceed with the install? Did everything go ok? Was there any problems?"

It was a really cool touch, after a while of conversing I was invited to go to their HQ to tune the car, there mr. Maciej helped me tremendously with setting the amp properly, supervising the install itself and many many other topics which at this point just waterfalled from my speaking hole.

I do recommend this upgrade, the sound difference is night and day and lately I have thrown in a subwoofer in the trunk using available channels on the amp, amazing!
