How do I route power wire for amplifier in 97 musang GT

[rodamp]

I a have a 1997 Mustang GT and I am trying to route a power cable for my amp in the trunk. How can I get the cable from the battery in the engine compartment into the car? I don't see any hole cut that go through the firewall. All the holes that go through already are filled.


Thanks in advance.

If you have an automatic, you can usually drill a hole where the clutch would usually go, check for clearence before drilling.
