You could use the speaker pins on the rear DB-15 of the transceiver itself & bring them out of the consolette. There are no speaker outputs on the 2 DB-25 connectors on the rear of the consolette, according to this info here:

Unfortunately, there's no way to adjust the speaker volume if you go with the above.
I've paralleled an external speaker off of the MC3000 remote, hardwiring with the standard 2-pin Spectra speaker connector & securing that to the remote chassis. Worked well.
