Original speaker Watts ?

[AMXguy]

I'm going to try to get my original 8 track to work but I know if you use modern speakers you'll trash these old radios. anyone know what specs the originals were?

the original radios were low watt output , I think the high output were 20 w or so
the real issue is matching the ohms generally 4 ohms
