[. . . ] Causa/Solución El fusible se ha fundido. El cable de toma a tierra no está firmemente conectado. t Conéctelo firmemente a un punto metálico del automóvil. La tensión que recibe el terminal remoto es demasiado baja. ·No ha activado la unidad principal conectada. ·El sistema emplea demasiados amplificadores. Compruebe la tensión de la batería (de 10, 5 a 16 V). · El indicador POWER/ PROTECTOR cambia de verde a rojo. · La unidad se calienta de forma anormal. Emplee altavoces con una impedancia adecuada. ·Funcionamiento estéreo: de 2 a 8 ·Funcionamiento en puente: de 4 a 8 Las salidas de altavoz están cortocircuitadas. t Rectifique la causa del cortocircuito. Los cables de conexión de alimentación se encuentran demasiado cerca de los cables con terminales RCA. t Manténgalos alejados entre sí. El cable de toma a tierra no está firmemente conectado. t Conéctelo firmemente a un punto metálico del automóvil. Los cables del altavoz han entrado en contacto con el chasis del automóvil. t Manténgalos alejados del chasis.

In a 12 decibels/octave system where both a choke and capacitor are used in series to form a circuit, great care must be taken when they are connected. In such a circuit, there is going to be an increase in the current which bypasses the speaker with frequencies around the crossover frequency. [. . . ]
