Retrofit Subwoofer on High Performance w/o Subwoofer

[thermal-fixity]

I've ordered a B&W sub. Fortunately, the seller also had the wiring plugs from the B&W set. Decided the full B&W system is a bit pricey - will consider it later if one pops up for a good price.

How did you run the wire from the AUD to the sub? Is there a factory diagram or something?
