MASSIVE AUDIO HiLo Car Subwoofer Line Converter

SKU CH-1ZFC-5FJWY

Converts speaker-level signals to 4.5 V RCA outputs with auto turn-on and remote 12 V trigger

  • Plug-and-play converter adds a subwoofer without losing factory features
  • Auto music sensing turns the amp on whenever audio plays
  • Balanced 4.5 V RCA outputs deliver clean, low-distortion signal
  • Ground-noise isolation keeps the audio path free from hum
  • Compact housing fits behind the dash for a tidy install

Factory Radio Integration

This HiLo converter connects a factory speaker-level stereo signal to any Massive Audio amplifier, producing a clean 4.5 Volt RCA output without giving up steering-wheel controls, navigation or hands-free phone features.

Ideal for Lease or Daily Drivers

Buyers who want a simple subwoofer upgrade without cutting factory wiring will benefit; installers needing adjustable gain, crossover or EQ controls should look at a processor with those features.

Supplied Molex Connector Simplifies Wiring

The included plug taps directly into rear deck speaker terminals, while automatic music-sensing turn-on and a 12 Volt remote output eliminate the need for a separate trigger wire.

Questions about this item

What existing speaker-level outputs does this HiLo converter tap into for its signal?

It connects to the left and right rear deck speaker terminals using the supplied Molex connector to capture the factory stereo signal.

How does the converter integrate with the vehicle's original 12 V electrical system for remote turn-on?

It features music signal sensing for automatic activation plus a dedicated 12 V external turn-on lead that ties into the factory wiring for reliable amplifier triggering.

What RCA output voltage should I measure to confirm the converter is delivering the correct line-level signal?

The dual balanced outputs are fixed at 4.5 V, so a multimeter reading near that level on each channel verifies proper operation.
