AudioControl LC1i 2-Channel Line Output Converter & Line Driver – High-Performance Signal Booster for Car Audio, Clear Noise-Free Audio Upgrade

Very good LCI YOU NEED THIS UNIT IF YOUR CONVERTING YOUR ORIGINAL CAR STEREO TO A AFTERMARKET AMPLIFIER I HAVE TRIED DIFFERENT LCI BUT THIS ONE WAS THE BEST

これは最高の商品ですね

Installé dans une sono de voiture afin d'éviter de mettre le gain de l'ampli à fond. La raison ? Bien les autoradio Android venant de Chine ne délivre pas assez de volt dans les RCA, le LC1i est donc nécessaire afin de ne pas pousser l'ampli à fond. J'ai choisi la sécurité et ajouter des fusibles en plus dans le coffre, histoire de protéger les câbles. C'est pas donnée comme produit mais très utile (acheté 125€ le jour de ma commande)

Works great easy to install with provided detailed instructions.

Hooked this up to 2, 10 in speakers (one box) and it works perfect, sound is not distorted by any means, relatively easy to set up great for the value, build quality is great. Had slight issues with the remote but worked it out after wires were hooked up. Over all, quality is great

Using factory head unit in my ‘21 Kona, connections are simple. Only using the front speakers as input which than hooks into my amp. Amp is 4 channel but 2 are bridged to run sub. As it relies on an input signal from head unit, if volume is very low it will not detect the signal and not turn on also if what you are listening to has a quiet spot or dead air, it will shut off after 30 seconds or so, power save feature.
