For those with the Boost CD audio system, I found something interesting...

Hidden under both front seats sit 2 little woofers. My previous car (2010 3-serie) also had subwoofers hidden under the front seats and out of curiousity, I took a look in my Countryman and was surprised to see those there!

Take a look under your front seats and you might find them!

 

Do you have the HK sound system? Those are a feature of it. Also they only have 20 watts running through them and can only handle 30 watts total. That's why there is no real thumping bass.
A member on here called theta has done extensive research into this.
