AudioControl LC1i Active 2-Channel Line Driver & Line Output Converter for Adding Subwoofers or Amplifiers to Factory Car Audio System, Replace OEM Head Unit, Impedance Matching, Distortion Free

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.

What else can we say besides IT WORKS! I used it to replace a passive line converter. This allows me to send a significantly stronger signal to the amp. Set it and forget it!

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 works great as a line-driver

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.

Works great easy to set up.

Needed to add a sub to my stock system. This work as expected.

They sent me a returned item first and I had to request a replacement in order to get what I paid for. There was a return label on it ("LPN" number and qr code) and the package was opened. This really has nothing to do with the product itself, just Amazon or whomever thought that was a good idea. Thats the reason for 1 less star. As for the LOC itself, so far so good. Unfortunately I have a factory radio that turns bass down as volume gets turned up so this wont be in car long, but it does exactly what it said and has worked flawlessly, allowing me to integrate an aftermarket subwoofer and amp with my factory amplified system. GTO works great and gave me a remote wire to use for aftermarket amplifier. Very easy to install if you know what you're doing and you can easily get settings adjusted by following a few videos. Its rather compact and easy to operate thanks to its design.

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.
