Audio again. Kicker key 200 from enfig.

I have posted here recently concerning wanting to upgrade my stock audio in my 2024SE. You guys have been very gracious and helpful thank you so much. I have decided that I don’t want to do a lot of change to my stock system.

I sat in my Tiggy on Saturday evening and listen to some Handel Concerto classical music with my eyes closed. And it was just beautiful. I love all types of music from hard rock to classical. But I love being able to hear individual instruments in clarity. From what I have read here in reviews and on other forums, the kicker key 200.4 amp from enfig should give me a little bit of upgrade in clarity without having to do major modifications of my system

Now, having said that my question is for those of you who have installed this amp in your Tiguan, how easy was it? I have watched the video on the enfig site. I’m 62 years old. I used to install my own stereo equipment years and years ago. But I don’t want to do any damage to my new car. I’m pretty confident I could take the glove box out and install the amp, my concern is putting it all back together.
