Mercedes Sprinter 907 center speaker dominant. LI82.85-N-071147 

Did this a month ago and the stock factory sound system sounds much better, no longer like a speaker in a tin can.

Confirmed works. Make sure to swap the greys too… basically cables to each connector switch Sounds soooooo much better

Tanks from Portugal

I just did this took ten minutes and now its perfect

Did it. Very Nice...sound is a lot better.

I did this in my 2022 from Düsseldorf and I found it better, but still too tinny. Disconnected sounds better, to me.

I think its easier to clip the wires and use Wago type connectors than swap the wires with the connectors.

Worked for me

just unplug the connectors...trim the side tabs off...reinsert into opposite position they were in......fixed ! ...sounds much better
