Answer
Hi Ted,

According to my information, the subwoofer amp is mounted right on the subwoofer.  You can connect the SOEM-T there, if you can access the wiring between the amplifier and the subwoofer's speaker terminals.  This would probably require unbolting the amplifier assembly from the subwoofer to get to the wires.

You might be able to connect your amplifier to the Bose subwoofer amp's input wires directly, simply by cutting the ends off some RCA cables and splicing them directly to the signal wires at the amplifier.  However, since you already have the line output converter, you may as well use it provided that you can get to the high-level wires between the amplifier and the sub.  

The yellow, black and blue wires are used with the SOEM-T's amp turn-on feature.  Yellow is meant to be connected to a constant power source; black is grounded, and the blue wire is connected to your amplifier's remote terminal.  When the SOEM-T detects an audio signal, it automatically turns on the amp.  However, you don't really need to connect these wires unless you want to use the auto turn-on feature; in your case, you can just connect your amplifier's remote wire to the blue/red wire at the Bose subwoofer amp, and it will work just as well.

Hope this helps!
