The best factory upgrade for base and HiFi systems on a budget it's probably the best summary for this video. In this video I talk about the differences between all factory options, install HK speakers and play some test samples of different combinations of speakers. Previously I installed HK speakers in my BMW F20 with base system which was a great improvement however, the HK tweeters were always almost annoying due to a different equaliser to factory HK setup. I decided to do the same in my F87 which came our from factory with HiFi system and I ended up with the same problem. So, I decided to experiment and I found HiFi tweeters installed in F3x and F4x. As you will see in the video, they giving much more pleasant tone which isn't too crisp.
I have to apologise for bad quality from the installation but I had to film it with gopro and I had stabilisation off.
