19 B&O upgrade NEED HELP

[PC 2015]

I have a 19 with the B&O in it. Want to upgrade but keep it simple. I was thinking the JL Audio factory location sub. But lost after that. Not trying to break records just little more bass and sound.

Thank you
Joe

Sub'd. I'm looking to upgrade the Shaker pro in my 2018 also. I've thought the B&O would have been much better in the 19 models and i was very disappointed that i missed out on that option.
