I have a 2005 Chrysler Town and Country. I want to install a kenwood TMG 707a and a Alinco Dr235 t . I have a rigrunner power pole cables . The antennas are both mag mounts. I have external speakers for both. Where have you been able to snake the power cable through the firewall. My question is where to mount this stuff. I want to mount this equipment out of dog range. I have a crazy tri color tick hound who is like a bull in china shop.
