2012 Stereo Question

Anyone know what package comes with the ENTUNE radio and the sub behind the rear seats? Or do all the Double cab 2012's come with a sub mounted behind the rear seats? Have also heard about speakers located in top of the cab? truth or rumor? Has anyone heard what this system sounds like?

 

i just purchased a 2012 trd double cab v6. It comes with the entune but to the best of my knowledge there is no sub behind the speakers...unless you get the power pak i think.. I would just like to know how good it actually is. I hate these bluetooth systems that dont actually do what you tell them to do... even when you tell them to f off..haha..
