 Yes! what you need is a heavy duty ring pull latch, the exact same kind they use on drop side trucks.
i used these years ago on Barn doors (horn extensions) and what you also have to do is put speaker grill foam between the door and the the cab to stop vibrations.
another aternative is heavy duty ratchet straps, just shorten them and add a couple of rings (cab and door) to attach your hooks to.

1metre extension with DOUBLE the 1850 mouth area at big end.
 eg 4000cm- > 8000cm
 
3minute approximation of 1850 =
Your looking at +6dB or so near flare cutoff with one horn in 2pi + extender.
 
Im not fully sure what the flare is on an 1850/

Its no big deal. A flare extension for the labhorn would be much the same - double the area in a metre or 1.5metres path length. Ofcourse id brace it heavily(unequally) as the dimensions are getting pretty big and you dont want some added 120hz peaky panel wobble :P
