I'm not able to find any hole through the car interior to exterior at the driver side of my car. I need to run my power cable to the battery.

My car is Mazda 323 2001 model, can someone give me leads ?

 

Sounds like you are running a power cable from an extra amp or something.
If you remove stuff underneath the brake pedal area and remove the car battery, you can get a real good look and just drill a hole and put a rubber grommet around it or some silicone. Make sure you add an aextra ground wire to the battery as well as your stock ground won't be enough.

 

thank you !
