Through a rubber grommet already in the firewall. It's tight but you can do it.

And if you do search you can find answers to most system work here on the forums. When I did mine, I referenced through the search feature at times.....and helpfully

If you pop the grommet out, and carefully exacto or razor blade a slight cut to get the lead through (like a coat hanger) you may be able to do it, I ran thicker wires in a snake for my fogs through one - then a little tug on the wire stalk should pull the grommet back into place.
It was easier than I thought - trust the stalk - you can pull it to get the grommet to pop out and back in

Use a wire, usually 10 gauge, and tap into the fuse block. This piece is called a fuse tap and any auto parts store has them. The fuse tap gets shoved into some secondary power fuse on the fuse block and pick it whether you want power on all the time or not. The owners manual has this information, if yours is absent just dl it. I have done this in the past and always spliced in a fuse of the appropriate amperage in the wire for a safety.
I dont like crawling around under the dash and to me this is the easiest and best way.

I've run 0 gauge through my gen5 as well..only thing was, I drilled a hole through the firewall and got a grommet to fit the whole so there's no harsh rubbing.. One thing I'll mention when you're working with 0 gauge, pull apart your driver seat and the rear seat it to run the wire, it makes life SO much easier..run the wire under the carpet but at an appropriate location so you dont feel or see the bump from the wire.. yours should be very easy to bend and move because kicker is pretty flexible...

don't forget to do the big 3 either :) that will help you greatly till u get a H/O alt. I'm still using an factory alt :(
I've got an Rockford Fosgate T2001 mono on two 12 Image Dynamics IDMAXs, and a alpine mrp-345 4 channel.

just my .02

I just ran it through the grommet and ran it under the door sill thing and it looks like fine like there's no wire under it at all. yeah in my old camry i was running the same setup im going to put in the new camry. I had a 160 H/O alt i bought off ebay and it worked great. I saw a h/o alt on ebay for the gen5. Yeah i also did the big 3 in my old car but in this car im installing anything until the h/o alt is installed first. I'm getting it custom built from excessive amperage for about 375 shipped he quoted me.

I have an 07 V6 and needed to run power from the battery to the rear and had to break down and take it to a stereo installation shop. It's not in my nature to pay someone for something I can normally do myself. I could find NO traditional rubber plugs and he couldn't either. He searched all over and under the car and eventually nicked a hole to the side of the steering shaft seal and used that point to plumb the zip cord. He snaked it up, around and through some of the other engine wiring and hydraulics before it led to the battery where it was fused on both poles. If these cars have other grommets in the firewall that are useful for pulling wires, I'd love to know where they are, exactly, if for no other reason than to just know.

yeah man it took me a while, but i finally found a gromment on the firewall its so big idk how i missed it lol. if you look under your steering column towards the upper right you will see a whole bunch of wires and then pull the carpet out a little and then you see the gromment. I just took my hyperflex 0 gauge and pushed it through and pulled it out and it worked out good. Then i ran hid it under the door sills on the driver side all the way to the back of the trunk. keep in mind i have a I4 so idk how much room there is in a v6 i heard its pretty congested.
