Anyone know where the easiest location in rear of xc90 passenger side is to access the wires leading to the Bowers and Wilkins subwoofer? Also looking for a remote wire location in rear of vehicle if known. Looking to add a sub to the system

Figured this one out. Wires for the sub are purple and yellow/gray. I can tap into them by the fuse box in the cargo arra without taking any panels off. Thx

For anyone interested. I did find a good way to add additional bass to the bowers and wilkins system and I di not need to remove any actual trim panels.
Added a fuse to the rear fuse box for seat heater. Tapped into the subwoofer wires (purple and yellow/gray) right next to fuse box in rear cargo area.
Ran power off the battery in rear and ground to bolt near battery in rear. Then I simply ran a remote wire up to front and hooked it all together. Running 22 speakers now.
