I would like to take a look behind the cargo area side panels (2023 Outback Wilderness) as a feasibility assessment for installing a subwoofer and some audio amplifiers. I have not been able to find any videos or pictures and I don't really want to break anything. Any recommendations would be appreciated. I suspect that the cargo tie-down hooks cover some bolts, but I don't see a way to remove the tie-down covers -- I have tried a bit using my plastic trim tools.
