560SL Amp Wiring
 

I tried this in the car audio section, but no one responded....so maybe someone knows in the general help section.
I have installed an amp in the trunk of my 87 560SL. New speakers in the rear deck. I have been trying to find a good way to get the wiring from the passenger compartment to the amp and back again so I can use this new system. Does anyone have a location or way of passing wires through?

open the trunk and you will see the panel against the fuel tank.i think there are about 20 small 10mm head screws on the floor and on the top holding panel.take these out and you will see many ways into the pass compartment.
