Autokemat Car Audio Converter: 2-Channel Speaker Wire to RCA Line Output for Subwoofers & Amplifiers

Upgrade your car audio with a smart, simple adapter

The Autokemat Car Audio Wire to RCA Line Output Converter bridges your factory or aftermarket head unit and a powered amplifier or subwoofer. By translating speaker-level signals into RCA-compatible inputs, this compact adapter helps unlock potential from your existing setup without replacing the head unit. Expect clearer midrange, fuller bass, and more responsive dynamics when your system is properly driven by an external amplifier.

Key benefits at a glance

• Converts high-voltage speaker signals to low-level RCA signals, enabling new amplification without RCA outputs on the head unit.
• Supports 2-channel or mono configurations, letting you scale your system for a dedicated subwoofer or full-range amp.
• Gain adjustment lets you tailor bass and level matching from the install site, reducing the need for constant amp retuning on the road.
• Compact, easy-to-wire design that integrates with OEM or aftermarket radios, aiding a clean, tucked-away install.

How it fits real-world setups

• Ideal for adding an amplifier or subwoofer to a factory radio that lacks RCA phono outputs.
• Works with OEM system upgrades or aftermarket head units, providing flexible input or output options for your speakers.
• One dial provides precise matching, helping you achieve balanced bass without needing to pull over to adjust the amp.
• Relay-based power activation minimizes extra connections and helps power the new amplifier without extra wiring complexity.

What you get and easy install tips

• Package contents: 1 converter for two-channel use and a connecting cable, ready to integrate with most car audio setups.
• Install quickly by tapping into a speaker wire and connecting the converter between the speaker and the amplifier; it senses the signal and powers the amp via a relay.
• Tips: Plan routes to keep wiring tidy, avoid heat sources, and test levels with the vehicle’s ignition on to confirm operation before driving.
