Connection SLI 2.3
The two-channel high/low adapter Connection SLI 2.3 is a reliable solution for connecting an external amplifier to an original car radio that lacks low-level RCA outputs. Thanks to advanced technology and precise workmanship, it ensures clean signal transmission without interference or distortion. This adapter is designed for easy integration into modern OEM audio systems and provides a stable foundation for improving the sound in your vehicle.
This adapter uses high-quality transformers that preserve full bandwidth and provide galvanic isolation between the signal source and the amplifier. The STOP NOISE technology effectively eliminates electrical interference and noise that often occur when installing additional audio equipment. The robust and compact shielded aluminum chassis also provides mechanical durability and protection against external electromagnetic influence.
Integrated DIP switches allow the adapter to independently set the attenuation ratio for the front and rear inputs. You can choose between High-Power mode (ratio 8:1) for integration with powerful factory amplifiers with voltages up to 35 V RMS, or Low-Power mode (ratio 4:1) for standard factory radios. The device also features speaker load simulation on four channels, preventing error messages on modern OEM units that detect speaker presence.
For maximum ease of installation, the adapter is equipped with automatic switching based on the presence of an audio signal, which works reliably even with radios without BTL output voltage. When a signal is detected, the adapter generates a stable 12V Remote output to trigger the connected amplifier. The connection is simplified by clearly labeled wiring with a durable Molex connector and a wiring diagram printed on the bottom of the aluminum chassis.
