Where to run amp power wire through firewall???

[BeeMain]

Hi,

I'm running a 4 ga to the trunk. I'm at the firewall and I'm not seeing a good place to go.

There is a big gromet just to the left of the steering wheel shaft (when in the car). This doesn't look bad but it seems to be two sided. I cut a slot on the inside but it not through. Inside the engine bay I can barley see were it is. It's obstructed by the fuse box (which doesn't seem to want to come out!).

Any advice? it's a 03, 3.4L

What's the best way to get at the gromet I'm talking about above? (if that's the one to use).

There is anther one behide the fuse box and at the top of the firewall but it goes into the area under the wineshield whipers, doesn't really help.

Let me know.

thanks
