Default best place to run power wire through firewall??

Where is the best place to run power wire off the battery into the car? I only see one rubber gromet with wiring behind the battery but could't fit my hand to see if that was it.
any advice?

it makes it a lot easier.... what i did was pull the battery out.. then pull the entire firewall grommit out, took my knife and slit the grommit.. it takes a little work because the rubber is really tough.. pull the power wire through the grommit then wire everything. after you've got enough slack and everything is where you want it, silicone the grommit around the area where you stuck the power wire, then place the firewall back to how it was.. it's not the quickest way to do it, but it's the proper way to do it if you want to keep moisture out

Yea you have to pull the battery then i just used a hanger to carefully poke a hole through the grommet and then i taped my power wire to the hanger and pulled it through.

that must be really small gauge wire for it to be able to be pulled through by a clothes hanger... you definitely won't be able to pull a 4 gauge through.. possibly an 8+

All you have to do is tape the power wire really well so it wont slip off and the hole will get bigger
