Anyone know anything about the Nissan factory amplifiers? Power output, input level, location, pinout etc? I have a '99 Maxima I'm currently installing and I'm having limited success. I know factory stuff isn't popular here but I want to exhaust all possibilities before ripping it out. So far I've tried speaker level signals and line outs but neither seem to match the factory level, speaker being too high and line being too low (sigh).

 

Do you have the base or Bose factory system?

I have the FSMs for most maxima years in .pdf format. I could email you the EL section for a 99.
