Some factory audio amplifiers employ a load detection circuit that looks for a low-impedance load in order to enable audio output. When a high-impedance load, like the input section of a FiX™ DSP, is connected to these factory amplifiers, the audio signal will mute.
The JL Audio FiX-LSA-4 Load Sensing Adaptor for FiX-82 or Fix-86 is designed to provide a low enough load impedance to enable audio output in most of these situations. Simply disconnect the input connectors from the FiX™ DSP, insert the FiX-LSA-4 in-line and recalibrate with the FiX-LSA-4 in place.
Note: An additional FiX-LSA-4 will be necessary if your FiX™ is connected to more than four channels of audio from your OEM head unit or amplifier.
