Mosconi HLA-Slim (HP)

The Mosconi HLA-Slim (HP) is an exceptionally compact 2-channel high-low adapter designed to integrate additional amplifiers and DSP systems into existing car audio systems. It converts the speaker signals from a factory radio into high-quality RCA signals, thereby enabling the retrofitting of car hi-fi components even without existing preamp outputs.

Designed specifically for modern OEM audio systems, this adapter is suitable for high-performance factory radios with BTL speaker outputs. The built-in remote detection uses the DC voltage present at the speaker outputs to automatically turn connected amplifiers on and off. A separate remote wire from the car stereo is therefore not required.

Thanks to its extremely slim design—which eliminates the need for an additional plastic housing and connectors—the HLA-Slim (HP) can be installed directly in the vehicle’s wiring harness or behind the car stereo to save space. High-quality signal processing with low distortion, high signal-to-noise ratio, and reliable interference suppression ensures clean signal transmission.
