After looking at all the setups here, I think I went overboard. I've got 2/0 coming off a group 31 battery to a Safety Hub 150 under the hood.
I then ran 6 gauge wire to the back of my drawer system where I mounted a DC-DC charger, distribution panel and fuse block for my radios.
Next, I ran the low-voltage control/speaker wires up the driver side sill plates and up to the center console. I have a Gamiviti wedge dashboard mount to which I mounted the heads and speakers. This isn't completed as I was in a rush to get this in before a trail run that happened last weekend.
The antennas lines run inside the passenger cargo area plastic shroud, up the D pillar, above the headliner, through the dust boot to the rear hatch, and out the hatch via 2 plastic plugs on either side of the hatch to mounts on either side of the roof rack. You can see one of the plugs that was removed and a Ford grommet part put in it's place that fits perfectly. The other colored wires you see are for rear hatch lights that I haven't put in yet.
The antenna base is a Diamond C213SMA (13.5' line) on a Diamond Super Gainer K540 mount. The antennas are both 2m/70cm Diamond HR770HB.
I'm running the Kenwood TM-D710G and the Wouxun KG-1000G. I know I could use the Kenwood for GMRS comms, but I wanted to keep within FCC regs. Plus, this setup is really what I was looking for, because I can have 2m trail comms on A SIDE of Kenwood, APRS beaconing on B SIDE of Kenwood, GMRS trail comms on A SIDE of Wouxun, and weather alerts/one-on-one comms on B SIDE of Wouxun.
The antennas fared well on the trail. They did bend but didn't break and I was able to bend them back. If I can ever get front and rear bumpers, I'll probably move them to those locations.
Next steps are cleaning up the wiring mess that is the center dash mount. I need to make wirepassthrough cleaner for all that you see. Then, I need to figure out the issue with the Kenwood mic. It's a known issue that when you extend the Kenwood mic line, you can introduce a 10Hz clock signal on your transmits. I have tried crimping my own CAT8 cable to isolate all mics within a foiled pair of wires, but I can't figure out a way to ground that correctly to eliminate the ticking. I'll get there eventually.
