I installed a JL Audio 8W3V3 in my B&O 2016 RS7 with the stock amp and love it .
You definitely have to heat the box to stretch it to get it in the stock box if it isn't deck mounted.
Do you have a 6 or a 7?
Lots of options but plenty of info to peruse, and probably some new options as I did this 3 years ago
