High-Low adapter premium 2-channel Line Driver

High-Low adapter

A high-low adapter is used when the OEM radio does not have low-level outputs / RCA outputs to provide signal to an amplifier.

The speaker outputs are connected to the high-low adapter and the transferred signal from the RCA outputs of the high-low adapter is used as input to an external amplifier.

Vehicle-specific T-cable harnesses are used as an installation aid for trouble-free retrofitting of an installation.

Line Driver / Extender

Line Drivers amplify weak preamplifier outputs from devices to match the RCA amp input for optimal tuning.
Signal level boosting prevents noise caused by interference in the signal path.
