In general it has a separate amplifier. If the radio has a big grey cable with a plug on the end, that plugs into the amplifier. If the radio has speaker output(s) on the back of the radio, then it does not take a separate amplifier. I think there might be one Mexico model that doesn't have a separate amp, but that is the exception to the norm.
FWIW, DIN plug becker stereo amplifiers are compatible with all becker stereo radios. Monos with monos.
