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

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.

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

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.

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.

I’ve got an Android stereo in my 2015 Jeep Compass. It’s great in every way except the RCA outputs for L/R and sub have low voltage. This unit boosts the signal so you can set the gain without cranking it. The signal is nice and clean, and it’s easy to install this unit behind the Android stereo somewhere because it’s small. I love this little thing and for $50 you can’t beat the price and quality. Frequency response is 20hz to 50khz, so it’s fine for my uses. Just make sure to set the switches and settings right. Don’t max out the output knob, keep it at 90% or lower and adjust the amp gain accordingly. It’s always best to have a little headroom in every component for the cleanest signal.

I love this thing. I'm glad I didn't chince out for one of those cheap options. Using this to piggie-back a couple ancient 8ohn speakers onto my 5.1 left and right channels. Works like a champ.

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.

Turns on soon as u turn on the car and its nice and small doesn’t take up alot of space nor does it take alot to set it up

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.
