AudioControl LC2i PRO

The LC2i PRO join ranks with AudioControl’s most popular active line output converter, the LC2i. Adding a sub? Planning a full system? Either way, get the best possible signal from your factory sound system to your amplifiers. Load selection switches mean OEM integration has never been easier and the LC2i PRO will work with the most finicky factory sound systems.

Frequently Asked Questions (FAQ)


Check the "Trigger Mode" switch. If using the "GTO" (Great Turn On) setting, the unit looks for a DC offset from the factory radio. If your car doesn't provide this, switch it to "Audio" or run a manual 12V wire to the "Remote In" terminal.
A solid red LED means the internal signal is clipping (distorting). Turn down the "Main" or "Bass" output knobs until the LED only flickers occasionally or stays off. This ensures a clean, undistorted signal is sent to your amplifier.
This is "bass roll-off" designed to protect factory speakers. To fix it, turn the "AccuBASS" Threshold knob up until the "AccuBASS" LED lights up, then adjust the "Level" knob to bring the bass back to your desired punch.
This is usually a timing issue with the remote turn-on. Use the "Remote Out" delay jumpers inside the unit (requires removing the cover) or adjust the "Load Selection" switch (20, 60, or 20k ohm) to better match your factory amp's output.
Many modern cars (like Dodge or Chrysler) look for a speaker "load." Set the LC2i PRO "Load Selection" switch to 20 ohm. This trick fools the factory system into thinking speakers are still connected so it doesn't shut down the audio.
Yes. The LC2i PRO requires a constant 12V power source and a solid ground to function correctly. Do not "tap" into a small 22-gauge radio wire; use a 16-gauge or 14-gauge wire to a fused 12V source for stable performance.
Ensure the cable is "clicked" into both the knob and the LC2i PRO. Also, verify that the "Level" knob on the unit itself isn't turned all the way down. The ACR-1 acts as an attenuator for the level you have already set on the main unit.
Always tap into the factory subwoofer wires if possible, as they carry the full bass signal. If tapping door speakers, ensure they aren't "filtered" by a factory crossover, or you won't get any low-end signal for your new sub.

Great Product

The following review is for a previous version (LC2i).

I used this with a stelthmod from JL Audio. The amp and sub set up were nice, but this made it incredible! All the bass that was taken out by the head unit was restored with this. Check Youtube for the step by step setup instructions to get it dialed in, then sit back and enjoy the bass!

The best LOC IMO Period!!

The following review is for a previous version (LC2i).

There are many LOC's on the market and many different ones depending on your needs but this to me was just all around perfect and the performance IMO is off the charts. I called the company - Audio Control - themselves to ask some questions about the LC2i before buying and there customer service was really good. They were knowledgeable and friendly. My system goes - 2009 Acura TL Base with factory radio, bluetooth, hands free link, 6 dics cd, XM Radio, and USB iPod integration. I installed a 10" Infinity Kappa perfect pushed with a JL Audio HD750/1. The only thing I did was unhook the 8" factory sub and ran the LOC through the factory sub location. This gave me control of the sub through my factory head unit as my radio has controls for the sub alone. I did not have to remove my radio for this install due to the fact that I used the built in remote lead to amp function on the LOC this is one thing that drew me to this particular LOC as I didn't want to run a separate remote wire from my radio or fuse box. I read that this LOC remote wire function gives you the "Subwoofer pop" when first turning on the vehicle but I have NEVER found that to be the case. It is whisper quite at all times with no feedback at startup whatsoever. I have a dedicated power wire running straight from the battery to the LOC and everything else is standard install AMP, Sub etc. The BEST thing about this LOC though is the "AccuBASS processing for correction of bass roll-off" which in my setup works VERY well. It seems to really bring out those low notes that the factory amp tries to roll off and does it seamlessly. I would recommend this LOC to anyone. It has great control at a fair price with easy instal and great features.

P.S. I also installed infinity reference 6.5 all the way around in my Acura TL to replace the factory speaks. They are 2ohm speaks which are the same as factory. This combo with the factory head unit and the sub has been an incredibly affordable alternative to a full system redo and sounds immaculate while keeping all the functionality of the factory system with LOW power drain.

great for factory upgrade

The following review is for a previous version (LC2i).

I used this in my wife's 2013 Toyota RAV4 for a 3 channel amp upgrade. It was pretty easy to install and the small size enabled placement behind the dash. I did some research before I hooked this up that made the adjustment settings alot easier. The sound is amazing!!!! I will never use a cheap loc again!!! Audiocontrol is a must have in my installs from now on!!!

Not too bad

The following review is for a previous version (LC2i).

Connected it in my 2012 Acura TL with Tech package(ELS system). Works pretty good, needs some time to tweaked for the bass to kick in at the proper time but overall not too bad at all. Recommend.

Quality, but didn't work in my install

The following review is for a previous version (LC2i).

Great made product. Factory amp caused an obnoxious amount of distortion through this converter though. Had to ditch it for a new headunit.

Great product for Sub integration into a factory system.

The following review is for a previous version (LC2i).

AudioControl as always is wonderful. Super easy to adjust, easy to integrate into the stock system, and easy to tune. I would deffenetly recommend for a cheap $20 LOC the build quality and tunability will be worth the money.

A MUST if you use an underseat sub...

The following review is for a previous version (LC2i-4).

I wanted to install an underseat powered sub (Cerwin-Vega VPAS10) in my wife's SUV so she would not attract thieves or lose any cargo space. The factory system was nice, it just lacked bottom end. I considered a PAC adapter so I didn't have to cut or splice wires, but I ended up using the LC2i from my other car and I am glad I did! The LC2i sends a strong 8V signal to the VPAS10, and that makes all the difference withe those units. The accu-bass was just a bonus for me, it allowed me to turn down the bass on the factory speakers and dial in the exact amount of bass without the door panels rattling; the sound was just so much cleaner. It was a night-and-day difference with the LC2i, clean voltage matters!

Needed a boost

The following review is for a previous version (LC2i-4).

I'm running a sub off the rear speaker output from a stock head unit signal and due to bass roll off, the sound was not as full as I wanted it. I ended up setting the accu-bass feature on at all volumes because my bass roll off is not volume dependant. Now the sound is much more full and volume is not an issue. I am happy with the results, easy install, and would recommend to anyone with my type of set up.
