2015 Sportwagen TDI S, MIB2 upgrade. Stock tweeters in the A pillars, stock front and rear door speakers, and it has stock rear door tweeters.
EQ set to flat.
57 sounded very muddy and bass heavy, mids and highs were quiet. Sounded almost like the speakers were rear biased, not driver focused, with overpowering bass.
60 sounded "louder" with the mids and highs more pronounced, bass was also good - gave more of a true "flat" EQ sound. More driver centric sound stage as well. Tweaked the bass EQ up 2-3 clicks, turned mids down 2 clicks, kept treble at middle. (How I usually set up my EQ in a car, mostly listen to rock and metal. Sometimes I bump up treble but that's not needed in this car with the front tweeters) I like this method because it gives me some headroom to turn up the bass for other genres if needed, opposed to #57 where the sound was bass heavy and unbalanced.
Couldn't tell the difference between 57/97 or 60/98 honestly. MAYBE a hair quieter, but nothing notable.
Awesome upgrade for the price. Also, if anyone buys this from VW right now, there is also 15% rebate for VW Accessories.
