Got my ecoboost with 201A package. I expected substantial bass from the sub in the trunk but even when turning the bass up to max using audio controls I don't seem to be getting much of anything from back there. All the bass seems to originate from front speakers. Would love to hear from others with this package. Everything else about the car I love

 

I can tell you I have the shaker, non upgraded one. And it sucks. No volume or bass at all

 

I have the shaker and the car has plenty of bass for me, but I do agree the rear sub doesn't seem to do a whole lot in the grand scheme of things.

 

Mine has plenty of bass. If your expecting it to shake the car or annoy everyone around you with that low frequency thumping, your going to need to spend some money on a high powered sub. I am a big rock fan and, in my opinion, this system really does a good job of covering the sound spectrum.

 

Spot on post! I agree 100%.
