Just taken my system out of my old escort to run the power cable from the battery to the amps. Right, in my last escort i had to drill a whole to feed the cable through, it ran just behind the glove compartment and down the left side of the car.

My problem now is just bought another one and i dont really wanna be drilling a through hole. I've looked at the side of the battery, the left wing seems to have a big area open and to feed it down and through that area would be perfect but i'm not sure where it comes out.

I just need to run the cable without drilling any holes (if possible)

Pointers if possible or advice please
