Anyone ever seen a genuine parcel shelf with original integrated speakers?

I found this yesterday morning, an original Renault parcel shelf with integrated speakers.

I was wondering if anyone else had ever seen it or knew if the speakers in it were any good. Also how would it of been connected up in a stock clio.

Not seen one for real, but I believe you have to disconnect your existing rear speakers to connect these.
