I had a service writer look it up for me. The SS 1LE specifically doesn't have a separate amp, like we deduced. It just has the 8" display and the "receiver", which is located fore of the glove box. Here's a drawing I was given, the perspective is looking from the front towards the aft of the car.

I was also told there isn't the ANC in the SS 1LE, due to the lack of a normal amplifier, however the wire colors going to the speakers is still the Blue+ & Brown/Blue-, and Yellow+ & Yellow/Black- for the front speakers. Sourcing from the rear speakers is an unknown and might not be full-range. Use at your own risk obviously.

Based on my searching in my own car it appears the easiest way to tap into the front channel high-level signal is at the bulkhead connectors behind the footwell kick-panel trim. It's not easy to get to, and you'll have to cut factory wires to splice in an external amplifier.


I hope this helps.
