AB  - In this paper we investigate stresses on loudspeakers in an automotive audio system using real world scenarios and thereafter develop a test procedure for evaluating their power handling capabilities. At first some general considerations about a given automotive audio system and the measurement setup, including measurement signals, are made. Then measurements of several state variables are made using automotive speakers, automotive amplifiers, and a selection of worst-case music content. After analyzing the state variables under load, we generate a measurement signal. To validate the method the same measurements with the same loudspeakers are made in a lab-setup, using the derived measurement signal. Those measurements are compared to derive a test procedure.
