The battery is under the hood in the accord, you'll need to go there for your power.

There is a 10mm bolt used to hold the lower half of the rear seat down that can be used for your ground.

You will need to disconnect the anc module above the glove box. But, you can also grab your remote from the anc connector.

From the battery to the firewall. If you have automatic , then there is a stamp on the firewall where the clutch would go if it was a manual. I used a step bit, drilled a hole that fit a 4ga grommet and ran my power thru there.

Or just drill your own hole , it’s simple with a step bit. Just make sure you know whats on the other side. So you don’t drill into anything.

Once you run the power to the back seats, remove those back seats, very easy, there anre YouTube videos. and you will see a path thru, into the trunk. I used the step bit again to make a slightly larger hole to the already existing one. Also in that same area there is a factory ground point , I just piggy backed on there , no problem.

you can tap into the rear speakers easily, if you plan to just use as sub, since the signal is not full range.

I can send pictures of these locations tomorrow. If needed.

 

Thanks, I might have found your post on reddit last night. I likely won't get a chance to look at it before the weekend, but will reach out if I need the pictures. Appreciate the help.

 

In my 9th gen there’s 3 holes in the upper kick panel next to the door wiring access hole.
