JL Audio FiX LSA 4-Channel Load Sensing Adaptor - Compatible with FiX 82 & FiX 86 OEM Integration DSP - Perfect for Car Audio System Upgrades & Professional Installations

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 FiX-LSA-4 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.
