PAC LP3-4 LocPRO 4-Channel Passive Line Output Converter

The PAC LP3-4 LocPRO 4-Channel Passive Line Output Converter lets you add an aftermarket amplifier or powered subwoofer to a radio that does not provide the RCA preamp outputs your new equipment needs. Its transformer-isolated passive design converts speaker-level audio to an RCA-level signal without requiring a separate power connection. It is a practical universal solution when a vehicle-specific amplifier interface is not required.

At a Glance

• Four-channel input and four-channel RCA output
• Accepts speaker-level signals from a compatible factory or aftermarket radio
• Adjustable stereo gain for matching the source to the amplifier input
• Rated for up to 55 watts of speaker-level input per channel
• 20 Hz-20 kHz frequency response (±1.5 dB)
• Compact single-harness design with wire-tie or screw mounting provisions

Compatibility & What You Need

• Source: Connect to full-range speaker-level outputs from a compatible factory or aftermarket radio. Do not use a bass-only factory channel unless the new amplifier is powering only a subwoofer.
• Amplifier: Connect the converter's RCA outputs to an aftermarket amplifier or powered subwoofer with RCA inputs.
• Vehicle connection: A matching PAC vehicle-specific T-harness can simplify installation in supported vehicles; otherwise the factory speaker wiring must be identified and connected correctly.
• Factory load sensing: Some radios require an AudioControl AC-LGD-20 or AudioControl AC-LGD-60 load-generating device. Use only when the vehicle or PAC application information calls for it.
• Amplifier wiring: The amplifier or powered subwoofer still requires correctly fused power and ground wiring. Those parts are sold separately.
• Professional installation and gain setting are strongly recommended.
