Hello, sorry if this is a stupid question but I need help setting the audio equalizer so that I get maximum treble and bass from my sub woofer and sound system. I recently had two headrest monitors installed and that reset my N2 to the original factory settings which sound pretty bad in my opinion. Anyway I'm not great with the N2 and would appreciate if anyone could provide information on setting the equilizer, loudness, etc... so that I get a good mix of treble and bass. Thanks in advance.
