2 speakers in old style stereo in one port

I picked a mirantz stereo prolly from the 80s of the side of the road, and hooked up some national speakers to it that i had at home. I also have some Akai speakers, is it possible to hook up all 4 speakers to it either through some adapter or by putting two speakers in each of the pairs of ports (its the jam the speaker wires in the red and black clip style) would appreciate any responses thanks in advance
