Here is the latest upgrade for the sound system in my 1998 Porsche Boxster. I replaced the factory Harmon Kardon amp with a 4-channel Alpine KTA-450.
This video shows the detailed process all the way from removing the old amp to installing the new one.
I have other videos on my channel that show how I already upgraded my speakers and head unit if you’d like to see the entire overhaul.
Hope this helps, as I could not find any good videos on installing an amp in a Boxster. Please like the video and subscribe! Some of the components I purchased are linked below:
