answering my own questions here but may help someone someday,
the four terminals are to run the amplified rear speakers,i ran them by connecting the #6 wire(white n grey from memory) to the amp/remote signal on the headunit and the speakers in the standard format,this works the speaker but with way to much gain,ie running full signal from the headunit plus the amps power.so what i need to do is connect these 4/5 wires to 2 rca and run them through the rca output on the headunit, or run straight speaker cables to the speaker and remove the factory amp

i presume you can do this (the rca adapter) will check jaycar and so on tommoz

rca output was to low and direct connection to high so i just wired them directly to the headunit (removing the inline amp) and all is well,worked out really well, nice headunit
