AudioControl LC1i Active 2-Channel Line Driver/Line Output Converter, Provides Input Signal to Add Amplifier to Factory Car Radio, Impedance Matching, Distortion Free

Works great easy to install with provided detailed instructions.

This thing is awesome. I bought an nvx xbbr2 but it seemed to amplify the wrong frequencies from my pac audio APSUB-TY12. So I decided to get this to amplify the 5v outputs of the PAC. Well worth it too. Still trying to figure out the parametric eq settings from the oac but with this I get the punch I want out of my system now. 2018 highlander limited with nvx 500w fitted box for highlanders hooked up to a stinger audio amp. Super small and only needs a 1 amp in line fuse. Worth it if you just need to amplify a signal without modifications. Noise level is good. No remote control was included. Setting it up was super easy too, just piggy backed off the amplifier power, I have the gain turned up all the way on this and still no distortion form my sub (about 3/4 gain on amp) . Maybe I'll have to switch out to my 700w sub instead.

Excellent quality, clear , powerful bass without distortion, worthy every penny, easy to install, the device practically comes “adjusted” from factory however I recommend that you set the output level knob to the minimum before you tune your amplifier to your own taste.

Works great. Easy setup. Just read the instructions. Makes sub install wayyyy easier.

This makes it so easy to connect an amplifier and subwoofer to a stock stereo.

I have a new ford explorer xlt and to change the radio isn’t that simple the infotainment system in the new explorers is very costly to add an aftermarket radio and changing the radio requires so many accessories and the radios available all change your heating and ac and power seat controls. Too much to risk. With that said I added a kicker line out comverter to add an amplifier. When I hooked everything up my sub sounded like trash and the signal was muffled and a lot of bass ranges on songs were missing. I spent over a month researching products to fix this issue I even tried a smart line out converter but that helped only a little. I found this line out booster in a car audio forum as a recommendation instead of the 1000$ I was about to spend on a digital sound processor and digital amp. I ordered this item thinking it wasn’t going to do much being this cheap. I was sadly mistaken. I added this to my stereo before my amplifiers and it boosted and cleaned up the signal beyond my wildest expectations. Every song is crystal clear and my sub works like it was hooked up to an aftermarket radio. If you’re adding a sub to any factory radio do yourself a favor and add this. I just added a distribution block to power the device and plugged in my rcas accordingly and tuned it to my amps. All in all took 20 minutes to install and my stereo is mint. If you’re not really a review person trust me and this review you’ll save yourself the stress and money… Edit: could just be the unit itself but after having for 4 months I’m now having to replace this unit. I’m running a pretty heavy system so with that much power things happen but was hoping would last longer. But totally worth the money

Installed several of these, never had an issue, always top quality, have never had one fail. Direct line converters are cheaper, but seem to always crap out and eventually start buzzing. If your going to dump money on after market speakers, amps, & subs, go ahead and pay for this now installing it correctly, than eventually end up doing it later. Also, remember you can run single power and split to amp and this converter, and also use the automatic remote function that picks up the signals from the audio to turn on your amp, so you don’t have to run a separate remote wire which I think is awesome. Good luck on your install.

I bought this because I have an Alpine head unit with very low subwoofer output; a common issue with Alpine and some of the other head units these days. I had to turn the gain on my sub up to 95% and the head unit sub out up to 100% to get an acceptable volume. After installing the AudioControl LC1i, signal level is improved, but not by the amount I had expected given the specs. I now have the Alpine head unit at 95%, the LC1i at 90%, and the sub gain at 60%. No perceptible noise or other issues, but I was expecting more of a line voltage increase than I got.

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)

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.
