I have the tech pacakge, but my speakers are Dimension. I can't seem to find any reference to Dimension on the Santa Fe Sport so I'm a little confused, unless Dimension is Infiniti which I was unable to determine.
Castaway nailed it! I've heard both and while the Infinity does sound better, the Dimensions system is nothing to shrug at. I would have been perfectly content with the Dimensions. The Infinity, however, will blow the panties off hot girls within a three block radius. It's science.
I have the 2.0T with the non-infinity system. It was okay, but this was the first car I had owned in my life without putting in aftermarket equipment in... so I've been used to good sound since i've been driving.
After about 3 months... I put in a kicker subwoofer. 10" powered box - $500 after install. Now, much better....
