Got the wires all laid from the radio to the amp, along with a couple of hot wires too back and forth. The head unit and 986 cubbie hole are in but not secured. Close enough to the done sign.
The sound didn't come out very loud on my phone vid, but it's plenty strong in the car.
Here are the wires from the amp to the speakers.
Here are the wires from the head unit to the amp.
And finally, the wires from the head unit heading to the amp and routed under the passenger seat.
