I have a 2014 durango with a K9 hot n pop system to open the windows and bl9ws the horn to alert the handler it's too hot in the truck. For some reason the horn only sounds 2 or 3 times and no more. This is from the system and by pressing the actual horn. I know it's a positive trigger horn. But is it operated through resistance or sommething? At a loss here.

AFAIK it uses a relay (located in the fusebox).
Maybe you battery is weak or the horn(s) require a high voltage (ie, when the engine is running) or there are bad connections.
IMO "only sounds 2 or 3 times and no more" suggests a battery problem else bad contacts in the high-current path.
Voltage testing would be good, but otherwise I'd suggest the usual rotate all fuses as well as disconnect & reconnect connectors. I'd assume the battery terminal connectors are fine otherwise the engine shouldn't crank (but it's worth confirming with a DMM voltage check).
Could even rotate (swap) the horn relay, but it's unlikely to be the (high resistance) problem. Nevertheless, its removal and refit should overcome connector corrosion as well as allow inspection.
The above assume all wiring is fine, and the horn/s is/are grounded and working properly. (First check - remove/inspect/refit horn ground?? And the horn working fine with engine running rules out thermal failures.)
I know it's a positive trigger horn. Usually they are -ve (GND) triggered - eg, grounded thru the horn ring - and the relay connects the +12V (inverts or converts polarity etc).
[ Traditional horn relays were 3 pin but these days normal 4-pin etc relays are used with 86 to 30 to +12V; 87 to horn +12V, 85 to grounding trigger (else GND to 85 & reconnect 86 to +12V trigger). ]

And AFAIK the only make using POS trigger to the relay is BMW.

While I haven't done a '14 Durango, I have pretty much stopped connecting the R/S's Horn output wire to newer
Chrysler products with my installs.
It seems to me that they are running the horn through the computer now-a-days. There is a distinct time lag
between when you press the steering wheel horn button and when the horn actually beeps. This lag makes
the R/S horn output time duration adjustment difficult. Too short a pulse ( 10 mSec ) and you get nothing and
at 1/2 second, it's too long/loud.
Using the horn wire found inside the vehicle is problematic. You could try using relays and going directly to the
actual horn in the engine compartment. ------------- Soldering is fun!
