I recently got the Volvo subwoofer kit for a V70 but the package
was missing the installation instructions. Can anyone provide
guidance on the wire connections for the Volvo harness for the
speaker. I have the speaker connections and I am drawing
power from the proper fuse on the rear block, but I do not know
the grounding point that is suggested or the connection for the
small guage purple wire in the harness that I assume is the lead
for the remote power-on switch to the amplifier. Judging by the
lengths of these wires the purple wire should connect
somewhere in the rear fuse block and the ground should be a
few feet away.

Any and all help is greatly appreciated. Thanks in advance.
