Awesome, I was looking at a sub like this, so I hope that I can get your feedback on it once it's installed!
You should be able to do this yourself. It should be pretty straight forward.
I would think that you'd take the positive cable and run it along the driver's side floor, tucked away behind the trim of the doors and then up through the dash and through the firewall. From there, you'd just connect it to the battery. I'm assuming there would be an inline fuse close to that connection as well.
You should be able to ground it in the trunk.
For the remote turn on, I'd think you'd need something coming from the head unit and that's the part I'm least sure about. I think I've heard that people splice into the rear speaker for that since it's close and would be pretty easy. Can anyone confirm?
