I have a 2015 s550 without 3d sound. has anyone upgrades the stock non 3d sound systems?
I was hoping to add just a digital equalizer or something simple without touching speakers. they seem to be good quality. just need to separate the highs and lows a bit more.

any suggestions?

I just ordered new 3D rotary tweeters for my non-3D 2014. I will create a new thread with a review. Here's what I purchased...

has anyone experimented with amplifiers to inside speakers and aftermarket sub? I have an extra w3 laying around, thinking about buying 3d tweeters and overhead dual speakers to add on the inside.

does trunk of 3d sound equipped cars have sub enclosure from factory I can retrofit in? part number? I would like to keep things looking stock as possible
any ideas or advice is appreciated thanks

I've decided to leave my 2015 S550e Completely Stock and Not install the 3D Rotary Tweeter Set from Carphone Car Electronics Co., Limited, shown above. It can be installed in any 2014 to 2017 S550, it is Not compatible with the 2018 because the of 64 colors. I'll sell it $295. Shipped USPS Priority, Please PM me if you are insterested. Thank you! Bill

I know this is an old thread. But where do you get the tweeters in this video? Do the ones you were selling do this?
