The Pro Series Line Output Converters all have AC-LGD's built into them!
The Pro Series LOC's are designed to present NO load to the output of the factory amp, which can make some factory amps upset and stop passing audio or change the way it is outputting to protect the source unit or OEM amplifier depending on your situation
The Load Selection feature tricks the factory amp in to detecting a speaker load so it will continue to pass audio.
20 Ω – Best suited for late model Dodge/Chrysler/Jeep vehicles equipped with OEM base sound system. (no separate factory amplifier)
