Internal speaker loudness will vary dependent upon external speaker impedance.

With a 4-ohm or 8-ohm external speaker, most of the audio will be directed to the external speaker and it will be much louder than the internal speaker.
The internal speaker may be completely disabled, if desired, by unplugging it inside the radio. Refer to radio service manual for control head removal instructions.
Connect radio main power leads to a constant (un-switched) power source.
Connect this cable's single red lead to a fused +12V ignition source and program radio to enable ignition control.
