Introduction
Thank you for purchasing Bimmer Tech products! We strive to deliver the most functional, reliable and
high-quality BMW retrofit upgrades on the market. Our kits are do it yourself friendly, but if you’re not
fond of working on your car don’t worry. You can always take your kit along with these installation
instructions to one of our recommended installers or to any other professional installer in your area. If
you will be handing the installation over to a shop from outside our recommended list ideally it should
specialise in BMW vehicles.
If you will be installing the kit by yourself then it is recommended to do so in a clean, spacious, well lit
and climate controlled garage without pressing time constraints. It’s also possible to perform the
installation in a driveway or parking lot if you prepare the correct tools.
We have a dedicated amplifier installation video for the G05 X5 chassis albeit in a regular Hifi car as
opposed to a Harman Kardon equipped one. There are a couple of differences between these
installations though:
1. The power cable has to be connected to the power terminal of the battery while the ground cable
needs to be connected to a nearby ground post. Any nice and thick unpainted bolt attached to the
chassis will do.
2. Instead of connecting the PnP harness to only one module - in a HK G20 our amp needs to be
connected to two modules.
3. At this time we do not have a bolt on amp mounting solution for G05 X5’s equipped with the
Harman Kardon system. Our mounting solution for Hifi X5’s made use of an OEM bracket (which we
supplied in the amp kit) that was not present in Hifi equipped G05’s and in HK G05’s it is installed from
the factory and occupied by the second factory audio module called the Booster.
For these reasons you will need to find a suitable spot for the amplifier nearby the factory audio
modules. We specifically made the PnP harness fairly lengthy to allow placing the amplifier further
away as needed.
Here is our Hifi X5 installation video:

The installation requires disassembly of various areas of the vehicle so it’s best to take your time, be
gentle, careful and diligent in keeping track of which screw and clip came from where in order to
reinstall the parts correctly.
