I have beep pokeing arround in my 2011 Base to try to find somewhere to stuff either a sub amp or a 5 channel amp (may do an alpine power pack + sub, not sure yet) and I am finding the designers did a very good job of using the space available to its max. Kudos to the designer, but where am I going to stick an amp out of the way. :P

 

Couple of folks have used the spare tire well... with or without the spare tire.
