Yes you can! Just be aware that if you are running more than one Paragon3/Paragon4 locomotive on the rails at the same time then you will need to have CV212 set to a different value for each locomotive (the receiver will scan channels 1-4 over and over again by default until a valid channel comes within range). A valid channel would be any locomotive with CV212 equal to 1, 2, 3 or 4. Two locomotives on the rails at the same time with the same value programmed into CV212 will interfere with each other. It is possible to have two receivers feed one sub woofer using a "Y" cable: Click here for purchase Plug one end of that cable into your sub woofer, each of the other ends to a receiver, and then set one of your receiver's lower and upper scan channels to the same value (CV142=1 and CV143=1 for example). Next set your other receiver's lower and upper scan channels to a value that is different than the first receiver (CV142=2 and CV143=2 for example). Finally, set CV212=1 in one locomotive's decoder, and CV212=2 in another locomotive's decoder, and this way you will have one receiver dedicated to each locomotive, and they will both play through the same subwoofer. Be aware that if you send too many locos through the sub simultaneously (you could theoretically send 16 receivers through one sub all at the same time if you wanted to by utilizing a mini mixer), eventually it just starts to sound "garbled" because there is only one speaker cone trying to produce sound from several different sources all at the same time.
