I would like to somehow adapt the sub harness to plug into the RCA connections and the "on" lead on the Sony deck.
Since the Subaru sub only has speaker-level inputs, the easiest
way to install it would be to connect to the speaker outputs on your Sony deck.
The sub automatically activates when it senses sound on the left channel, so there's no need to use the Sony's "remote on" line.
Assuming you used a wiring adaptor ("forward" harness) to connect the Sony into your 911, you can buy a reverse subwoofer plug
from me and wire that in between the Porsche forward harness and the Sony harness.
Or if your sub came with the factory T-harness, you can cut off the long leg and wire it in between the forward and Sony harnesses. If you're careful not to cut any of the wires running between
the two 14-pin connectors, you can sell that portion to a Subaru owner who wants to wire an external speaker amp to their factory radio.
One of the guys on the ScoobyMods thread (see link from my HU FAQ thread) talked about the possibility of hacking the sub to use line-level inputs, but unless you do that kind of electronics tinkering a lot, you'd be better off just buying an after-market sub that can take line-level inputs, like the Clarion SRV303
