I did it. Once I removed the screen along with the cubby. There are spaces you can feed a wire over to behind the glove box. From there zip tie it out of the way and wire into the fuse box. I did not take any pics or videos b but it was pretty simple.
I'm seeing $799 on there website as well. The subwoofer in the box alone is $350. I had the stealthbox for my Toyota Tacoma and loved it. That one was $1000. They build them right here in Florida. Great product, but you pay for it. Maybe if I ever get some time and feel like getting into car...
