    Good Morning,

    I own a 2018 Prius 2 eco and want to add a small sub and amp in the back. I see plenty of threads on doing this however none seem to address the issue of getting 12v from the battery under the hood to the hatch area of the car.

    Please, if you have solved this share how. I really don't want to drill holes in my firewall.

    There is no free thru holes in firewall at all? Maybe between some another cable etc?
    Just make sure that you paint edges of the hole good if you go and thrill hole. That way it wont rust so easily.

    Personally i am against for thrilling any holes to car. That opens road to rust always and what ever you do to cover it, wont be as good as original paint was... just IMO.
    EDIT: i see you are from Las Vegas and i am from north, so i have to deal harsh winter salt what you dont:)

    The second day I had the car a friend and I tore the whole dash apart looking for a way in. I was in a small panic seeing all the panels scattered across the garage, so I can feel the passion in your effort. Thank you for sharing!

    There is a fuse panel to the left of the driver's left knee that has accessory power. I used a fuse tap (use Google to search for one) to power my Fog lights.
