Hello, everyone! I installed a Kenwood subwoofer in my 2003 Volvo V40 and now I want to unplug the cables of the stock one because I don't need it anymore. The problem is I don't know how to reach the inside of the plastic cover on the right side of the trunk.

Just to mention I don't want to remove the sub, I just want to unplug the cables so that it stops working.

Appreciate all replies!
