You did fine on the speakers. If I had my fat, 240lb, 6' 4" *ss up in my trunk, damned near anyone can do it.
Getting in the trunk on a normal g body isn't a problem, getting into a 2+2 is the problem! I can barely fit a 215 wide spare tire through the gap. There is about a 8 inch opening max.
It's like spelunking I guess 🙂
