you have another version of the Fujitsuten Hu , it is the first time that i see a HU with a Pioneer amplifier but it can be because all the "screens" (oem monitor) are Pioneer and the ML version is only a MArk levinson amplifier with a Pioneer HU
. For finding you need a multimeter ,set it in AC mode and test each wire until you find a signal ,more easy is to get an osciloscope
I doubt about directly use the ouput converted as rca , the general ohmeter is not the same as speaker level or RCA level you will take the risk to get whine noise or noise floor

It seems it is difficult to pick the signal cable before the pioneer amp then go into the new amp.
Instead, I may pick the speaker cable after the pioneer amp and feed into the new amp by high level input.

Any idea for picking the signal cable before the pioneer amp?

Honestly I have always pick after the factory amp and never had any problems with noise or what so ever. I personally think u should wait until I give u the diagram. So at least you kno what wire is what. So yours is the 8 speaker system?

That means pick the signal cable before pioneer amp and then bypass the pioneer amp and feed into aftermarket amp?

It seems the front woofer and tweeter are divided by pioneer amp.
Can I merge them in 1 channel then go into the aftermarket amp for amplifying?
