Four-Channel Line Output Converter

The Earthquake Sound HLLC-200 converts speaker-level signals from a factory stereo into four RCA outputs for aftermarket amplifiers. It includes adjustable output levels and an automatic remote turn-on circuit for the amplifier. Nickel-plated RCA connectors maintain clean signal transfer. Professional installers value the detailed workmanship and integrated noise elimination.

Suited for factory stereo upgrades

This converter suits owners adding amplifiers to a vehicle with no pre-amp outputs. It accepts two speaker-wire channels and expands them to four RCA channels for multi-amp systems. Buyers who already have dedicated RCA outputs on their head unit do not need this device. Vehicles requiring summed signals beyond two input channels should verify compatibility before purchase.

Questions about this item

How does the 200-watt rating affect the signal level sent to my aftermarket amplifier?

The 200 W figure indicates the maximum speaker-level power the converter can accept from the factory stereo before converting it to a clean, adjustable RCA signal for the amplifier.

What connection standard do the RCA outputs use and does it limit cable length?

The converter provides nickel-plated RCA connectors carrying an unbalanced line-level signal; cable runs up to several metres are practical without audible loss.

What mounting space and wiring access does the unit need inside the vehicle?

The compact chassis fits behind the dash or under a seat and requires only speaker-wire input leads plus four RCA output cables and a remote turn-on wire.
