Speaker Operation
Speakers turn electrical energy into mechanical energy to move air, using a permanent magnet and an electromagnet. The electromagnet is energized when the radio or amplifier (if equipped) delivers current to the voice coil on the speaker. The voice coil will form a north and south pole that will cause the voice coil and the speaker cone to move in relation to the permanent magnet. The current delivered to the speaker is rapidly changing alternating current (A/C). This causes the speaker cone to move in two directions producing sound.
The base (no amplifier) speaker system on the convertible also includes a self-amplified subwoofer. The subwoofer receives audio input from the rear audio signal circuits. The subwoofer assembly receives power and ground from the vehicle harness. The radio controls the power state of the subwoofer via the remote enable circuit.
