4-Channel High-to-Low Converter

Tapped into my factory head unit’s speaker wires and the RCA outputs came through clean — no noise or distortion even at higher volume. The compact size made it easy to hide behind the dash, and the 4-channel setup let me run my amp without swapping the radio. Install took under an hour.

Was skeptical about tapping into my factory stereo without RCA jacks, but this little guy made the install painless and the signal to my four-channel amp is clean with zero noise. The wiring harness is straightforward enough that even I could figure it out in an afternoon.

The compact size made tucking it behind the dash totally painless, and the 4-channel setup gave my factory head unit a clean signal for the amp. Zero noise or hum after wiring it up, which surprised me for the price.
