I am new to my 2014 Range Rover, and when we got the vehicle it did not have a manual - so I am putzing around the on-screen navigation to find things out. The Harmon Kardon stereo system's sound quality is not as good as I expected. Right now I am running 320 KBPS MP3s through a USB stick (I am currently waiting to get the Land Rover > iPhone cable) - the speakers, which are not blown, sound fine, but the refinement of the bass/treble/mid settings does not really bring out any amazing quality of sound.

Are there more advanced tweaks that I can make to the sound system? How powerful is the stock amp, and how many channels is it? And, if anyone knows how to obtain a user manual and where - please let me know, and it would be appreciated.

Thanks for reading!
