Prior to acquiring an ACC cable to interconnect my KPA500 to the K3s I used an 
RCA WYE cable to allow me to parallel the KEY signal from both the K3s and the 
KX3 to the KPA500.  This has worked well allowing me to get about 350 watts out 
of the KPA500 when driven with the KX3.

After reviewing the KPA500 schematics it appears that pin 10 in the ACC cable 
is diode ORED with the KEY In jack so connecting the K3s via the ACC connector 
and the KX3 via the KEY IN RCA jack should work as before.

Is this correct?
