What I would like to do:

Keep the factory HU.
Keep the factory speaker wires.
Add amps
Add subs
upgrade speakers.

1. Is there a part number for a plug adapter to the amp? I dont want to replace the HU but would like to avoid splicing.
I see fully inclusive kits that have them....but none seem to be available by itself.
2. If no adapter is available is there a correct JBL wiring diagram? Everything I have found is for older JBL or non.
3. Does the factory HU send line level signals to the amp I could tap off of? I would only need a L-R line signal. I would like to avoid line level adapters off the powered side of the amp. Being able to tap off of the line in would be better.

Anyone have advice on this? I know the 'jbl' thing has been beat to death but I have not been able to find an answer in weeks of research.
