I am going to put this here as there really is not a better place for it.

As an amature radio operatior I need to wire a seperate power feed to my radios. I know that a lot of modern cars use power monitoring and extra power feeds can cause an issue with this unless it is done per the manufactorers directions. (VW has a big problem with this)

Does anyone one know if the CH will have with issue with extra power draws? Did Jeep make provisions for just this type of use?

I have no idea but being it was based off a car (Fiat) platform I am not sure they provided extra wiring harnesses. If they did your best bet will probably be a Trailhawk but I am betting you will have to experiment or go after market on this one.

Normally, I would too. But on some cars that perform voltage monitoring, wiring direct an cause issues with the monitoring system. VW is one os these and I noticed in the OM It states the CH also has a voltage monitoring system. I cannot find any information in the OM about wiring accessories.

I suspect the aftermarket is too new for this vehicle but they could at least touch base on it. I wonder how the Grand Cherokee handles this? The Wrangler probably has an older style wiring system.

The back of the owners manual has a section about wiring radios. They recommend running straight from the positive terminal on the battery (fused) and grounded to the body.
When I wired up my 2011 JK I just ran both wires straight from the battery and had no issues with the radio.

Great find. I was searching the owners manual and could not find anything on. Will go spelunking again. So they don't have an issue wiring off the battery which is good news. Easy enough to do.

I think it is funny they mention "Normal" transmitting power. What do they define as normal? Bet they are talking about 4W CB radios. Bet my 50 Watt Ham radio will give it coniption fits.

Depends on how well the resonate frequences of the transmission matches to the frequency of the vehicle electonics. Sounds like they have shielded them from the page you posted. I am guessing the VHF/UHF bands would have a greater chance of interferance than the HF bands.

And I do have a TS-450S that will put out 200 Watts I could try. :)
