I'm looking to install a set of powered backbox speakers (including separate amplifier) in my Tron Pro (2012). I found this reference to where one can solder in the wires to capture the audio pre-out (unamplified) from the SAM MPU board, but I don't have any schematics for SAM and I was unable to locate them visually.
STERN SAM PRE-AMP OUT
Stern Sam: Does not appear to be on a connector but test points are your friend. (TP10-Left, TP11-Right, grab GND from CN4 pin 7)
Can somebody post a picture of the SAM board with the location of these test points highlighted (and/or where I can get the schematics for the SAM boards)?
Much appreciated!
