I am currently tied in behind the factory sony amp to my RF 360.2. Not really happy with the sound and would like to tie into the lines before the amp, however i cannot find any diagrams that detail the colour codes of what should essentially be pre-amp level connections befopre the amp?

Any opinions or diagrams to help?

 

not immediate help, but factory service manual/wiring diagrams always pay for themselves (at least for me). i buy them for everything.
