Blue Tooth, Pandora, Navigation, touch screen, DVD...few other features other than better volume came with it too...
Driving with a girl recently: "You're playing a CD? You *burned* a CD? Does it stream? (I gave her a look at this point) Just how old are you???" ...young girls are so adorable
To get through college in style I owned a mobile audio and security shop in L.A. back when Viper Alarm was new. I used to hang out with Darrell Issa, judged IASCA, dragged in factory vehicles to sound offs, oh the parties, spiffs, and booze. I had 100's of T-shirts. Yeah, I'm old!
My 2003 Vue has a cherry sound system that was cheap and easy to setup. However, my 2008 Sky reminds me of trying and trying for years to get my VW Cabrio in L.A. to hit hard. Best solution was to board up the trunk access behind the back seat and put in two 10's with a Carver M120 running bridge-mono, each. Rear seats got 3 1/2" drivers in the panel with satellite tweeters at each upper rear seat corner, firing forward (or rear passengers would lose one ear's hearing). Doors got 5 1/4" with satellite tweeters in the doors. The tweeters, doors, and rear panels were driven by a single Carver M240.
The car totaled out at (RMS) 240w to each 10" and 60W to each corner of everything else. The 10's were Kicker free air's, 3 1/2's were Kicker, the 5 1/4's with matching tweeters were Polk Audio (super voice clarity), the rear tweeters were, hah, Magnadyne.
When I bought my Sky last year naturally I had fantasies about applying all the hard lessons learned in setting my my old Cabrio, but...
...I figured out it has the Monsoon system. I decided to only change the speakers, excluding the sub. I like the OEM look, don't want to deal with the systems integration they do these days, and the sound is acceptable. My Cabrio had a ton of hacking, chopping, laying of power lines and signal coax, and all the attendant debugging and fine tuning. I'm just not up for that again. Rather spend that time enjoying using the car, and save on the hassles. I can always "go Cabrio" on it someday if I like.
That said, I must agree that changing the speakers to the Infinity Kappa series (appropriate name!) only improved sound moderately. However, the Kicker 3 1/2" 2-ways I put in the rear panel made a big difference in imaging. Probably more sensitive, and, the addition of those tweeters helped.
The one problem I had was the inability to crank the volume of the amp anywhere near clipping on MP3 CD's. I solved this by increasing the dB of my MP3 tracks with a s/w tool called MP3Gain. It sets a parameter in the MP3 files rather than re-processing the track itself. Then, I noticed that I can increase the dB setting 6db higher for playback in my Vue (Pioneer MP3 player) than in the Sky's OEM player. The Sky will make clipping sounds at the pre-amp end at any volume setting. This kinda tells me the DAC's in the Sky's player aren't "as good" in some way, but that's not my area of expertise so I can't be more specific. I just bun CD's for both cars at the lower level so I don't need to produce two sets.
