I wasn't sure about the upgrade to alpine hifi, I was reading every thread about it and finally decided to give it a try.
The standard sound system was...too "standard" I was driving a BMW X1 2013 listening a 1950 car sound system
I did the upgrade last weekend and it's an amazing upgrade. Tweeters, Powerful sound and Clear. If you love music, you will be very happy with this.
PS: no coding required
