AV receivers never have bluetooth or any other wireless sub transmitter built in.
Many subs have transmitters that are made for them that can be connected to any receiver or you can buy a generic wireless sub system but your sub would need to have an RCA wired input that you could connect it too.
If the sub came from a JBL HTS system it may not be able to be used with anything else.
If the sub uses bluetooth you could try connecting a standard bluetooth transmitter to the sub woofer out of the receiver.
