Hi, I'm looking for a shop that will run a power wire from the battery through the firewall into the cabin. I want to install some amps myself but getting the power wire through the firewall seems tricky. Would like to find a shop that has experience on the best way to do this on my car. 2017 Prius prime. But the 2016 and newer Prius should be similar if not the same. Location near mid wilshire Los Angeles, or Buena Park is preferable. Thank you.
