i realize this is an old thread, i purchased a 2011 Sport/w moon & tune ( had a 2008 se same deal) june 29th. i am now just getting around to "fine" toothing it. little background, i am a musician, drums for 44 years. i KNOW a little about sound and audio systems. #1 where are the extra 2 speakers in this car? i ran the speaker diagnosis and it is saying 10?!?!?! what up with that? #2 there ain't no way on God's green earth that this system is 390 watts!! i play with a guitar player 18 watts and a bass player 50 watts,beside me every weekend, kinda hard to make the 390 watt claim here. 390 watts would pop the windshield out, well not quite but still, bad info on this system, it would be nice to know frequency responses, sensitivity levels, distortion levels, etc., etc.. actually as much as i love this car and WANT to like the audio system i cannot! let's see, adjust bass up and down, adjust treble up and down, fade left or right or front or rear, pretty basic stuff here. oh well, it's all about the driving experience in the end right?
