Hi, friends at pinside forum
Last month I received this tiny board that Lorenzo mentioned in this thread from pinnovators.com (I purchased the wire by myself to avoid shipping costs to Europe, but it´s nearly identical to the one they supply).

The board fits this way in the backbox, you can guide the output wire to the amp through the vent holes very easily (the other wire you can see here it´s an HDMI one from a DMD EXTENDER):

We connected it to a Pioneer A-204 Amplifier and two Sanyo 3-way-speakers with great results in a little tournament he had here in Granada, Spain:

There was a little background noise (almost unheardable, only at a very high volume), but I think attaching one of this filters around the sound wire the hiss would dissapear completely:

The combination is perfect for the public, they can have a great audio and video experience, enjoying a final without disturbing the players:

Of course you can attach the output of the tiny board to an external subwoofer, but I can tell you this way the atmosphere were outstanding.
THANKS TO THE STAFF AT PINNOVATORS FOR THIS PRODUCT!
All the best
