The speaker in the instrument panel is identical with the speaker installed at the rear, left-hand side. Both have a resistance of 8 Ohms, are switched on together, and in the case of stereo radios, are connected at channel 1. The right speaker (4 Ohms) alone is connected to channel 2. For mono radios both speaker lines are connected with a special plug. For older radios, whose speaker connections consist of two round plugs, a standard adapter must be used to match the new speaker wire connectors.
