Our take on the AudioControl LC2i

by Zak Billmeier
AudioControl

Looking for great sound from your factory radio? Would you like to upgrade your car's premium system? AudioControl's LC2i line output converter takes amplified speaker-level signals and converts them into high-quality preamp signals that can be fed to another processor or amplifier. In other words, it lets you create an awesome car audio system without disturbing your factory controls or features.

Get your bass back
Some factory radios dial down the bass as you turn up the volume to protect their speakers. The problem is, they don't give it back when you upgrade to a nice set of aftermarket speakers. AudioControl packs the LC2i with their AccuBASS™ circuitry that reverses the factory bass rolloff, giving you the bass you need to enjoy your music to the fullest. Place the LC2i between your factory system and your bass amp, and you'll hear a huge difference in bass response.

High-voltage signal for great sound
Some premium systems use multi-wire speaker cables for systems with multiple speakers. The LC2i features two speaker-level inputs that let you connect amplified signals up to 400 watts, including cables from Bose® and other premium factory systems. The LC2i then sends out a high-powered preamp signal — up to 9.5 volts RMS — that helps every amp perform to its maximum ability.

Convenience
The optional dash-mount remote control allows you to adjust the level of your sub channel on the go. The speaker-level inputs sense incoming signals and turn on the LC2i, while a built-in 12-volt trigger tells your amps or other gear to turn on when you start your car.

Highlights:

  • 2-channel active line output converter
  • designed to work with most factory systems

Specifications

Features

Overview: The AudioControl LC2i is an active, high-voltage OEM line converter. This compact, two-channel processor with active input circuitry, accepts speaker-level signals of up to 400-watts per channel from factory-installed source units or amplifiers. It then converts the speaker-level signals to high-quality pre-amp signals that can then be directed to after market processors and/or amplifiers. You no longer have to compromise when performing basic amplifier additions to factory installed audio systems. You can enjoy maximum sound quality while maintaining the use of your factory volume and steering wheel controls.

Compact Chassis Design: The AudioControl LC2i active, high-voltage OEM line converter features a compact chassis for an unobtrusive installation.

Two Channel Speaker-Level Input: The AudioControl LC2i features two channels of active speaker-level inputs that accept up to 400-watt signals. The two-channel line-output converter features four removable flat-head set-screw terminals for quick connection.

9.5V Preamp Outputs: The AudioControl LC2i is equipped with 9.5-volt preamp outputs w/ level matching controls. It features a pair of Main preamp outputs (for full-range amplifiers) and a pair of Bass preamp outputs (for subwoofer amplifiers).

Active Circuitry: The active circuitry used in the LC2i provides dramatically better sound quality and does not compromise the bass response.

AccuBass: The AudioControl LC2i features AccuBass processing for correction of bass roll-off. AccuBass processing automatically corrects for the bass roll-off that is common with many factory installed audio systems. AccuBass Bass Compensation works at any volume level.

Threshold & Level Controls: Simple "Threshold" and "Level" controls allow users to optimize the bass response to match their speaker system.

GTO (Great Turn On): The AudioControl LC2i utilizes selectable GTO auto sensing turn-on circuitry so no remote wire is needed. The LC2i turns on using the unit's speaker-level inputs. It also provides a 12-volt trigger output to turn on your amplifier.

Remote Level Control: The AudioControl LC2i is equipped with a Bass Control Input (RJ-11) for optional remote bass level control (sold separately).

Mounting: The LC2i features integrated mounting flanges to mount the unit under a seat, in the trunk, or under the dash. No mounting hardware is supplied.

Power Connections: The AudioControl LC2i requires a hardwired power and ground connection to your vehicle's 12-volt electrical system. The line-output converter features removable flat-head set-screw terminals for simple connection.

Wow, this thing is great. My '14 Silverado came with the Bose soundsystem upgrade. It sounded good, but needed more bass to sound "complete". The LC2I is the magic link that makes the addition of a subwoofer to a late-model vehicle so transparent and easy.
Pros:
Ease of installation, fits just about anywhere, works as advertised, economical
Cons:
vague connection information/no schematics

Great device

Written By ToddH, Milwaukee, WI on Sunday, December 15, 2013
Crutchfield Customer Review (What's this?)
 
I purchased the LC2i to addan additional subwoofer to my factory subs in a Chrysler 300. This device made it simple to just tap off one of the existing sub's speaker wiring for an input and gave me line level outputs to my Alpine amp for the new sub.The Great Turn On (GTO) circuit works well to provide a trigger for my added amp. All I had to do was run battery lines to the amp - a great benefit since finding a "switched" 12 volt signal on this car is about impossible with canbus control of just about everything! The Accu-bass circuitry works really well, too, providing me with just a small shelved boost in the lowest frequencies, since my factory radio already has pretty decent frequency response at all volume levels. I would highly recommend this unit for newer vehicles, especially if you have canbus controlled power everywhere.
Pros:
small size, well thought out design, excellent performance, virtually silent.
Cons:
documentation could be better, but still easy enough to figure out.

Big Difference!

Written By rolfer85, Oak Lawn, IL on Sunday, October 13, 2013
Crutchfield Customer Review (What's this?)
 
This product was advised to me by a Crutchfield tech support member. I have an 06 MINI cooper S that I removed the Harman Kardon system from and replaced with an Arc Audio MINI 4 channel amp driving Inegral Audio 6.5" Infinity 2 ways up front and 2 6" JL 6W3v3's in the rear. I called Crutchfield to seek help from a lack of bass. I would have to dial my stock radio's bass setting all the way up and crank the volume in order to get any sort of noticeable bass output from the subs. This was also after I dialed up the output on the amplifier. The tech support recommended the LC2i which I have since installed and immediately it has made a major difference.

The sound quality even from my front 2 ways are improved. Overall Rock, Alternative and Classical music all sound great with the LC2i knobs all at the center position. Rap music however is overpowering for the bass and I have to turn the bass knob down a couple clicks on the radio when playing bass.

Also, the automatic turn-on feature worked great for the LC2i, however for whatever reason, installing this no longer kept the functionality of the automatic turn on for my amplifier. No big deal though, I used the remote on output from the LC2i and wired into the remote turn on input for my amplifier.

Overall this has been an excellent product and probably the best <$100 upgrade I've made to my audio system yet.
Pros:
Small package- easy to fit/hide Great sound output Simple set up, I actually like that it only allows 2 channel mode F&R Well balanced output for everything but Rap
Cons:
Lack of 'troubleshooting' in the included 'instructions'- had to google what the red light meant (means on) Automatic turn on works for LC2i but killed the function for my amplifier Too much bass output for Rap music

Not bad

Written By gman9966, MA on Thursday, June 13, 2013
Crutchfield Customer Review (What's this?)
 
I think its ok. I dont listen to RAP and the bass boost is probably more suited to Rap which is more boomy. I like rock and I would have prefered a more dry punchy bass you can feel. What I get instead is boomy rap sound. I have played my sub that I used in this sytem in other vehicles using aftermarket headunits and I know what it supposed to sound like. This definitely adds the bass back, but the accubass it too boomy for me to give it 5 stars. Many of you younger folks listening to todays music will be delighted. It gives you very loud very strong pounding bass...its just too boomy for me.
Pros:
clean signal. Good for adding an amp to a stock head unit.
Cons:
should have had better control to shape the bass to what you prefer. dry or boomy

Didn't work for me

Written By MissileCrisis, las vegas on Monday, June 10, 2013
Crutchfield Customer Review (What's this?)
 
I must be the only guy thats had a problem with this LOC. I purchased it to based on the fact it had a 5 star rating from this site. And I'm always down to spend the money and get something thats right for the job. Long story short everything was hooked up "right" because redid it 3 times after the LOC wasn't working. The LOC has to be a defected product because I did my research and this LOC was acting in the manner that a defected product does. So waiting to get the same new one and will try this again people. Note that this review is based on the fact that I'm the rare person who has had problems with this LOC. This product seems legit and thats why I'm getting the same one. One more Note: the remote subwoofer adjuster didn't work when we plugged it in. Thought that was weird too :(

AudioControl LC2i

Written By Tom R., Upstate New York on Sunday, May 12, 2013
Crutchfield Customer Review (What's this?)
 
After researching different options, I chose the LC2i to add a stealth subwoofer to a newly purchased VW Golf. I have done numerous installs in the past, but this one differred as it is a "grown-up" application, meant to be undetectable (except to the ears). This Audiocontrol device is oustanding. The quality and quantity of the signal provides clarity and low noise, and the GTO function works perfectly, and in fact provided a switched 12 volt supply for the amp that was installed with it, a Rockford Fosgate R500 1D. The setup instructions are "subtle," to put it nicely. However there is a wealth of information available, as well as great customer support with Audiocontrol.
Pros:
High quality signal Tuning flexibility Excellent build quality
Cons:
Vague instructions

Worth every penny!

Written By Hags, Stafford, VA on Saturday, April 06, 2013
Crutchfield Customer Review (What's this?)
 
I installed this on my 2012 Dodge Challenger and this is one amazing LOC. I tapped into my rear right speaker and it gives an amazing, strong signal to my 300watt Sony amp. The signal quality is just as good a RCA output on an aftermarket radio but this device allows me to keep my Bluetooth, steering wheel controls and Satellite radio on my stock system. Install is easy for a rookie like me, took about 2 hours but most of that time was spent making a nice clean setup. I used a line tap(from auto zone) from my fuse box to power the LC2i.
Pros:
Great for amps that don't have adjustment knobs, signal is strong and just as good as an RCA, automatically turns on with your factory stereo
Cons:
none

LC2i Mustang Shaker 500

Written By Ernest, New Mexico on Wednesday, February 20, 2013
Crutchfield Customer Review (What's this?)
 
Product helped get me more sub-woofer volume from the stock mustang system that I installed an amp and a 10" sub in the trunk. The speaker level inputs from the Shaker 500 weren't doing a good enough job supplying my amp with a good signal. Tried two different brand loc's, went pure line level and I even bought another amp trying to nail down this issue. Since adding the LC2i I can now turn down my amp gain and have plenty of room to spare. Didn't notice any depth improvements in the low frequency ranges and the GTO didn't work but the sub-woofer volume range is improved and the whole system sounds much richer as a result. For me it was worth the money, thank you Crutchfield.
Pros:
Definitely improves signal strength to the amplifier inputs.
Cons:
GTO feature didn't work with my application and wish the lows were a tad bit lower.

Crutchfield Customer Review (What's this?)
 
I hooked the AudioControl LC2i up to my stock stereo in my 2012 Subaru Impreza with no issues. The directions were straight forward and easy to understand. After I hooked up my amp and sub woofer, I plunged the battery back up and was anxious to test this product out. At first, the amp didn't kick on with the remote wire that was attached to the AudioControl LC2i, but I quickly figured out that my fuse was blown on my power wire that connected my amp. I replace the fuse and was extremely excited that everything was working and the base that came out of my sub-woofer was amazing!! I am very pleased with this product and everything worked like it should. I would recommend this product to anyone.
Pros:
Easy to install, Great base sound from stock stereo, small and easy to hide
Cons:
None that I can think of

2012 mustang shaker 500

Written By Anonymous, Jacksonville, AR on Thursday, February 14, 2013
 
Works great with my shaker 500, you just have to set the accubass Threshold to the lowest setting then you can turn the bass level up to what you desire. The AccuBass you can leave in the middle or turn it up to add deeper bass to your radio since the shaker 500 does not have roll off bass.
Pros:
Best way to add bass to a factor radio Company support response time
Cons:
no directions for dealing with radios that don't have roll off bass

Highly recommended

Written By Jason, Greensboro NC on Tuesday, January 29, 2013
Crutchfield Customer Review (What's this?)
 
I first purchased a vehicle specific sub enclose with a 10" sub and built in 300W amp with built in hi-level inputs. It was rather high end and rather expensive. I tapped into the rear speaker wires for the input. I was so disappointed with that setup I wound up returning it, output was just subpar and even with the gain all the way up I could not get the bass level high enough compared to the other speakers. Thinking it was the equipment I went back to what I knew, a JL Audio 10" sub and this time a 600W amp to drive it. The amp also had built in hi-level inputs and I hooked it up the same rear speaker inputs. I once again was not happy with the volume level and had to resort to using the bass boost on the amp to get the sub volume up and was not happy as the bass response was no longer linear. Being more familiar with the equipment I now knew the issue wasn't there, it simply had to be the level of signal going into the amp as compared to the volume going to the speakers. I needed a stronger, louder input going into the amp. I picked up an LC2i and the difference is amazing. I went from being disappointed with the amp gain at 5/6 and the bass boost at 6db to now the sub hits very hard with the amp gain at 1/2 and the bass boost at 0db. (I'm not even using the AccuBass) I had no idea an external converter could make such a difference but the ability to control the signal level going into the amp really helped to get the full potential out of my amp and sub
Pros:
Sound quality and additional volume
Cons:
None really. It's another device to install but it's small.

Crutchfield Customer Review (What's this?)
 
I installed this product plus the optional bass remote on my Daughters new 2013 ford focus with my ford touch/sony hd/navigation radio with factory amp and factory sub in the trunk. I simply ran a power wire from the battery to the trunk where the alpine mrp500 was placed under the trunk mat. I used the the wires going into the factory sub for the input of the lci. No turn on wire required. Used the 12 volt off the alpine amp to power the lci. Boom turned on all the system and the two alpine twelves sound great. I did not even adjust the lci just used it how it came and turned the gain down to half on the amp which is powering two alpine type s shallow mounts. The bass knob on the dash made it great to turn it up when needed which is does need to be at all. Going to buy one for my new ford f150
Pros:
Easy install and way to add amp to factory system

I recently added a subwoofer and amplifiers to my factory receiver and have tried many line output converters including the pac models, but was less than impressed with the sound quality of these converters. I recently decided to try the Audiocontrol LC2i converter and was amazed at the improved sound quality! The extra dough for the audiocontrol LC2i is well worth it !

2011 F-150 Sony Factory Sub Replacement

Written By Steve, NC on Monday, December 31, 2012
Crutchfield Customer Review (What's this?)
 
Like many others, I don't normally write reviews on products purchased online. However, I rely heavily on these, so I thought it only fair that I write one that might help someone else. I purchased this to install in my F-150 Platinum in order to replace the Sony factory subwoofer and maintain the factory system. I used a JL 500/1 amp and 10" JL sub with an enclosure I built myself to place under the rear seat. I had already set up the amp installation with a local installer, but after deciding to purchase the LC2i (because the installer said he would need to use some sort of LOC) I thought maybe I could try this myself. 20 years ago I used to install car audio systems as a hobby, but a lot has changed with factory audio and the wiring has gotten a lot more complex. After researching some online forums I found that running the power from the battery to where I had the amp and LC2i mounted would be pretty easy. It wasn't until after I looked a little closer at the LC2i that I noticed it had the GTO feature. It took about an hour to run the power from the battery and get everything wired up (used both sets of DVC factory sub line inputs for signal), but once it was wired the LC2i worked like a champ. Using the GTO feature I avoided having to find a remote wire for the amp, and the LC2i picked up my incoming audio signal immediately. While I haven't finished tuning it, I can tell you that this is a MUST HAVE if you are installing a mono amp to replace your factory sub.
Pros:
Ease of installation and the GTO feature in place of a remote turn-on wire.
Cons:

Small than it looks

Crutchfield Customer Review (What's this?)
 
Ya know, my pet peeve is trying to hide these factory add on pieces just because you already have to find a place for the amp and wiring, but man this thing is tiny, it fit behind my wife's focus factory cd player no problem. Used wire taps (I know I know not the wisest choice, but they are holding strong) and the unit turns right on with the car. I went ahead and used the audio sensing feature but if it quits working I will tap into the switched 12v for the remote, but at the moment not necessary. The 9V max pre-outs are awesome, puts a super strong signal to your amp, I bared had to use the gain/trim. Great overall build and product, seems the company really stands behind their products. Didn't find any use for the accubass feature, I left all the dials in the middle and it worked out just fine, figured I would use the amp as my gain/trim....worked out just fine.
Pros:
Perfect for factory stereos, strong pre-outs
Cons:
None that I know of...so far

Awesome Sound

Written By Dave, NJ on Thursday, November 08, 2012
 
This thing is awesome, read a prior review by someone with a WRX and got nervous because it wasn't a good review, but I think that user installed it wrong. In the wrx you need to tap the front speakers as the EQ pushes everything to the fronts. The sound vs using the high level inputs on a kenwood amp is night and day. Sounds like it should sound. Love the adjustability and it just sounds insane! Get this now.

Works perfectly

Written By Johann, Elk Grove, CA on Saturday, November 03, 2012
Crutchfield Customer Review (What's this?)
 
The Audio Control LC2i works perfectly as advertised. My Mustang w/ Shaker 500 sounded good, but it lacked deeper bass. There are no Line-Outs on the head unit. The LC2i took a good audio signal from the door subwoofer outs and gave a strong signal to my new subwoofer amp in the trunk. The remote control for it works well too and it is easy to mount anywhere. Because the LC2i only draws 150mA, tapping for power was simple. A few caveats... the settings are a bit tricky to get right, but work well once you figure it out. The youtube video helps. A more detailed technical instruction sheet would have improved things. Lastly, the compact size made it a breeze for mounting. This LOC made adding an amplifier to my Shaker 500 a breeze and I would wholeheartedly recommend it to anyone wanting to improve their factory sound. A+ Product.
Pros:
Perfect design, flexible audio settings, compact, remote control accessory works well too. Not too expensive.
Cons:
Paltry instructions.

Audio Control LC2i - 2007 Range Rover

Written By Ben L, Ann Arbor, MI on Friday, November 02, 2012
Crutchfield Customer Review (What's this?)
 
I bought this unit to be able to add an aftermarket amp and sub in my 2007 Range Rover (LM 322) with factory stereo/nav/logic 7 surround sound. The car came with a weak factory sub/amp so I removed the stock sub and tapped into the wiring from the stock amp, after the stock sub. I was told to keep the stock amp because of the way the Range Rover electronics work. So I took the wires from the stock sub and wired them to the LC2i +/- line inputs.

What is nice about the LC2i is that it has Remote In, Remote Out, and a 12V+ terminals on it to be able to turn on/off the amp when turning on/off the car. You don't need a separate remote turn on. So I wired the 12V+ to a constant power source, and the Remote Out to my aftermarket amp, and both the LC2i and aftermarket amp only turn on when the car is is switched on.

Since I don't have one of those factory radios that plateaus the bass levels as the volume increases, I just adjust the LC2i's settings accordingly. I turned the Bass Threshold knob all the way up (clockwise), and then the AccuBASS knob + Main level knob + Bass level knob all the way down (counter-clockwise). However, I had to search online forums and what not for proper adjustment settings because the LC2i didn't come with any detailed instructions based on the kind of stereo you had. It just explains what the GTO and AccuBASS are.
Pros:
Remote Turn-On Two Sets of Line-Outs for adding up to two amps Level Adjustments Size
Cons:
No detailed installation or sound adjustment instructions

Best thing since sliced bread!

Written By Scott A, Paducah, KY on Tuesday, October 30, 2012
Crutchfield Customer Review (What's this?)
 
I'm 38, and back when I was younger, I used to install alot of stereos for friends, etc. Things have come along way since then, and this product is definately one of the best things I've seen! Its simple to install, and the adjustments are very straight forward. Its really compact, and I love the fact that it automatically turns on when it senses a signal from the speakers inputs. It also has a remote out connection, so you can hook it to your amp, and it will turn the amp on and off automatically too when you turn your radio on and off. It makes putting amps, etc so simple when running along with factory radios, and speakers. I highly recommend this to anyone looking to upgrade their factory system.
Pros:
compact design, auto on, off, and the ability to run a remote wire from it to your amp, and turn it on and off automatically too! The sound reproduction is excellent also.
Cons:
NONE

Works Perfectly!

Written By Todd M, Jackson, MI on Wednesday, October 17, 2012
Crutchfield Customer Review (What's this?)
 
Awesome product and it works as advertised in my 2011 Chevrolet Malibu. Here's a quick run down of how I installed this to help everyone out there. The really nice thing about this product is that you only need to run one wire from the front of the car to the rear and that is the power cable for the amp. Then I grounded the amp to the tailight bolt. So once that was done I tapped into the rear speaker wires from each speaker + and -. Ran those to the LC2i. Then I ran a small power and ground from the amp to the LC2i. Hooked up the RCA cables from the amp to the LC2i and speaker wires to the sub and that was it! The really nice thing about this product is that there is no need for the remote wire, as the stereo signal to the rear speakers does this for you. Tip- adjust amp to lowest level then go from there tuning the LC2i and the amp to find the best sound. I recommend this product as it did everything that it advertised.
Pros:
Easy install No remote wire needed Made in USA
Cons:
Instructions could be better

Simply Fantastic

Crutchfield Customer Review (What's this?)
 
This thing works! I didn't want to buy a new head unit for my '08 Maxima because I have OEM Nav and that would leave me with a big blank screen and no display for many things. I also wanted my car to appear stock to anyone with thoughts of breaking in. My car came with Bose speakers, so we just added this LC2i, 0 gauge wiring, a JL fuse block, a stinger distribution block, 2 12" JL Audio W3's and a JL 500/1 amp to run them. I was skeptical, but am now very pleasantly surprised. Highs are loud and clear and obviously the bass pounds. Perfect set up for me!
Pros:
Everything

Fixed 2011 Dodge Ram with Factory Radio

Written By JasonK, Olathe, KS on Friday, September 21, 2012
Crutchfield Customer Review (What's this?)
 
Had an issue of a severe lack of bass from a subwoofer I installed to my factroy system in my 2011 Dodge Ram 1500. The lack of bass was present when listening to Sirius Radio or mp3's. The cd player was ok. This little box fixed it! The bass is loud and proud. The rep I called at Crutchfield didn't think the LC2i would cure my problem. Let it be known, it cured it in a big way!! I would suggest this item for anyone needing a line out converter for integrating anything into a factory system!
Pros:
Awesome product that really works. Well worth the money!

Doesn't turn on, doesn't sound good once turned on

Written By Steve H, Nashua, NH on Friday, September 07, 2012
Crutchfield Customer Review (What's this?)
 
Ugh, where do I begin. I reviewed this product on multiple sites including this one to find out it is the best solution out there for using your OEM head unit with an aftermarket amplifier. Well, I can't say I agree. This is going to be one of those one off reviews where people gloss over it because the majority of reviews are heaping praise on the product and people won't take it with a grain of salt but humor me and listen.

I have a 2011 Subaru WRX and I'm keeping the factory head unit so I don't need to buy an aftermarket head unit, bluetooth and steering wheel adapter. Anywho, I tapped into the Right Rear speaker with a soldered connection for optimum connection and ran the wire to the LC2i. Ran the power cables from my capacitor to the unit, ran the remote wire from the unit to the amp (the amp is properly connected to the cap also), turned the car with the radio on, AANNDD nothing. The LC2i just sat there and slept. I played around with the jumper to make sure it was in the proper auto detect position, still nothing. I checked all the wiring again and again and still nothing. I resorted to running the remote wire from the accessory wire from behind the factory stereo to the LC2i and that turn the thing on, FINALLY. Phew. But the quality of the audio signal is less than ideal. The knobs to control the volume and quality didn't do anything and the overall volume was inconsistent, kept cutting out.

Needless to say, I'm getting better quality going directly to the amp.
Pros:
The concept is great. Small and lightweight
Cons:
Everything. The auto turn on didn't work. Once I got it turned on, the volume was inconsistent and kept cutting out. Power terminals too close to each other which leads to risk in the wires crossing and arcing. The signal it processed was causing the sub to only hit and not be smooth.

Pros:
Simple install, LOVE the GTO function!

This device was many great! I very much enjoy the bass now. It provide many sub levels that were not able to be heard. My bass was very missing on certain frequencies and I could only listen to street bass and metal-house, but now I can listen to hip hop! Make sure you turn down your bass boost on amp the lc2i and the amp will fight the battle of the bass.
Pros:
Easy to install . Accubass is the chronic I got a new girlfriend because she loves to booty shake to my bass
Cons:
Didnt come with a second one that I could give to my installer as payment for his many great hours of work put into my car

Crutchfield Customer Review (What's this?)
 
This product works very well. I have an MK6 GTI with the 300W DynAudio stereo system. I added a sub and quickly discovered the OEM stereo rolled off the bass. I was able to tune the LC2i perfectly using a SPL meter and test tones, and I'm thrilled with how well it worked. No more constantly adjusting my sub volume, and it hits cleaner, harder, and deeper! Great product!
Pros:
Corrects bass defeat in OEM stereo systems for a great price.
Cons:
Not the best setup instructions, but was able to figure it out.

Works as advertised

Written By Mike, Arlington, VA on Sunday, April 29, 2012
Crutchfield Customer Review (What's this?)
 
It takes speaker level inputs and converts it to something useful for my amp. I'm using this in my Audi A6 w/B&O to add a large subwoofer to the system. The auto-on feature upon detection of signal from speakers works well on the standard speaker lines but it doesn't for *my* install which is off the subwoofer line. Not a big deal, just needed to hook up a 12v source to turn it on. I'm pleased with the product.
Pros:
-Works well -Handles the 'high' power from the premium system -Tunable bass compensation (nice touch for those who need it)
Cons:
The remote bass control really should have been included in the kit rather than a separate add-on. It's a telephone cable and (probably) a variable resistor. Can't dock a star for this though as it is not a part of the package.

After being frustrated with numerous $20-$30 Line Output Converters, I finally coughed up the money for the AC LC2i. The price is more than reasonable for what the unit delivers. I LOVE that I can keep my factory head unit, steering wheel controls, nav, etc. The signal this thing sends to the amp is crystal clear. I used mine for a simple amp+sub install, and it sounds great!

Stop wasting time with cheap LOC's. This thing is perfect.
Pros:
Small size, easy installation, works exactly as advertised.
Cons:

The LC2i is probably the best investment I have made for my car. I have a 2003 Mercedes E320 and didnt want to remove the APS 50 radio that came with the car since it has navigation and I like the appareance. What I did is remove the original subwoofer in the rear deck of the car and hook up the LC2i from those cables and man does it do a good job. Everybody said that I couldnt install an after market radio because Mercedes uses fiber optic. Naaaahhh!!! With this little guy in my car, my car is loud!!! I also install dynamat in the license plate and there is absolutely no rattle just solid bass. I cant recommend the Audio control LC2i enough to anybody that wants to add amps to their car without removing the OEM radio. If youre installing an aftermarket amp in your mercedes completely remove the OEM sub to let the air go into the cabin and youre good to go also since the OEM sub is a dual voice coil you can use the second pair of cable to add a second amp to connect your door speaker if you want to change them. Awesome just awesome!!!
Pros:
easy install great voltage ouput for your sub accubass module for any OEM radio
Cons:
nothing at all!!

I hardly ever leave reviews on products, but I felt like I have to for this one. I have been a big car stereo enthusiast forever and always add subs to my cars. Normally I do aftermarket equipment but I like my factor radio and wanted to add some bass to my '12 VW CC.

I originally purchased a top of the line PAC converter hoping to get some good sound from my radio. After installation and tuning, it sounded decent, but very muddy and distorted when I turned it up. I delt with it for a while until I heard my buddy's aftermarket stereo and subs he just installed. I knew that there was some way to get my factory stereo to sound like his. I did a lot of research and ran across AudioControl's LC2i. With all the positive reviews and low price I decided to give it a shot. I ripped out my PAC with a smile on my face hoping to improve my sound. After I ran all my wires, hooked up the LC2i,I turned on the receiver and the light on the LC2i turned on. As soon as that first bass note came out of my subs, a huge smile appeared on my face. I couldn't believe how incredible it sounded before I even tuned it. I followed the instructions included with the LOC, and the sound that is coming from my car is unbelievable.

Anyone who is installing an aftermarket amp and sub with a factory radio, don't waste your money on anything else to get an RCA out. BUY THIS product and you will not regret it. Words cant express how awesome it works. Great job AudioControl!
Pros:
Best sound quality I have ever had with a factory radio Price is great for what you get American made Installation was simple Still baffled how good this product is!
Cons:
Not a single thing

Crutchfield Customer Review (What's this?)
 
Sometimes the highest praise is...it does what it says it will do. My JL 12W0 was not gaining volume like the front speakers and this wonderful machine gave me the bass I knew I should be getting from my Challenger. They shipped it without plugs and that annoyed me so I called Crutchfield and they had plugs in the mail the next morning. I emailed Audio Control and a real live human being called to apologize. I might have preferred it if no mistakes were made, but I got great customer service from both companies. I look forward to adding an Audio Control EQ over the summer.
Pros:
It gave my amp a great signal for the highs and fixed the factory limiting low signals.

Read all other reviews and was a little skeptical, but with 5 stars, they cant all be wrong. Simple to hook up, just tapped off of bass wires on the rear deck speakers, ran power to amp feed and mounted under rear deck, done! Wow, what a difference! Like other reviewer, had to cut bass setting on factory deck. My bass would drop out at number 15 on the head unit,adjusted the threshold at number 15. Difference of nite and day! Bass was still a little strong, so I fine tuned the accu-bass and gain controll. I was going to replace the head,but was debating cause I would lose control panel display. But Now I have all the bass I need and more! Thanks again Crutchfield for another great product.

I put this in my 2010 Toyota Tundra. The only problem I had was that I got my left channel out of phase (swapped the high level inputs plus and minus) oops. The subwoofer was muddled and wappy. After a quick call to tech support we got it fixed and BOOM! Tight,crisp, deep bass from a factory stereo. (I am running a 13 inch subwoofer with a 350W RMS amp) What a difference. The bass adjustments are extremely effective and the entire unit seems to do its job very well. The amp GTO signal sensing turn on unit works flawlessly as well. The LC2i is an excellent product.
Pros:
Excellent product that will put the Bump into your factory system.

Crutchfield Customer Review (What's this?)
 
I bought the LC2i to replace another bass restoration device while adding a full system to my car with the OEM head unit. The LC2i adds back all the bass that the OEM head unit strips out, gives a nice high voltage output to run to my amps and provides a remote turn on line by sensing power to the speaker-level inputs. The LC2i is very clean, no audible distortion added to the signal, unlike the device it replaced... I cant say enough good things about this device. The noise floor is finally low enough that there is dead-silence between tracks.

Installation was a breeze, power ground, speaker signal inputs and RCA and remote turn on outputs. Setup once installed took 5, maybe 10 minutes at the most and half of that time was playing with the device to see what it could do.

I was skeptical at first, as I suspect most people will be, but I am living/driving proof that this device is everything its advertised to be, and I couldnt be happier. Its worth every penny.
Pros:
Quick and easy setup powerful RCA outputs very clean (no noise added inline) small footprint
Cons:
Nothing

This is by far the best interface to use if you are just adding a subwoofer to your factory stereo. The stereo in our 2011 VW was already very nice sounding, just needed some sub bass. Added this in addition to a JL amp and Stealthbox and the sound is unbelievable. The bass doesn't roll off like a standard line interface would at high volumes. A++++

Written By Anthony, Pittsburgh, pa on Monday, September 19, 2011
 
This L.O.C. is great, i was previously using another loc, in my 2011 forester, and the stereo i built didnt sound much better than the stock stereo in my subaru. i had the loc ran into and equalizer, and still the bass was muddled and flabby, the highs were inconsistend and the mids were just awful, so i bouth the lc2i and what i difference it made. i took this stereo out of the last car i had, and put it in my subaru, the only difference is that i am not using an aftermarket head unit, and this loc sounds better than the exact same system with the aftermaket head unit. The only reason i didnt give this 5 starts is that i am only using the main outputs to run into my equalizer, and you loose some of the bass control with the unit when you do that. but if you are not using an equalizer, this things is perfect, its made in the usa, and its only this much, you cant beat that.

Ok, I went through three Maxxsonics MX-1's. After that, I was temporarily using a ten dollar LOC converter. Then, I decided to try a name brand LOC. It was the same result as the ten dollar one. So, next I decided to read up on the LC2i and thought that I would give it a try. Immediately it made a difference, but I had a little trouble tuning it. The Accubass function is a little challenging without a test speaker or an osscillascope. So I brought it to a local audio shop to have them tune it. Wow! My sub hits so hard and so clean now. Thank you Audio Control, Crutchfield, and Lakeside Audio.

Bought this product because my new JL 500/1v2 amp could not sense the high speaker level inputs to turn the amp on, but it worked on my other JL 250/1 amp. I have an 08 Chevy Avalanche with Bose and wanted to keep the factory look so I spliced into the sub speaker level outputs of the factory amp and ran them to my JL 250/1 amp. Worked flawlessly, but after upgrading to the 500/1v2 it would not turn the amp on using the signal sensing.(factory Bose amp only sends lows to sub...both manuals state that the high inputs need to be full range in order for signal sensing to work. Not sure why it worked on the 250/1 and not the 500/1) So, I needed to find a remote 12v source but came across this product with it's high level inputs , high voltage outputs, signal sensing with remote turn on and decided to give it a try. My only concern was that this product was not going to sense the sub inputs and not power up without a remote in. Well I hooked it up to my factory sub outputs and problem SOLVED! It powered up the unit which also sent power to the remote output (GTO) to power my JL and it works perfectly. All I need to do is fine tune the LC2i and my amp. Very happy, YEAH BOY!

Crutchfield Customer Review (What's this?)
 
I've never reviewed anything on the internet, but I wanted to say that I have recent experience w/ both the Scosche LOC80 and this product. I first bought the Scosche because it was $20 and I didn't think there would be a huge difference. I had it professionally installed (along with some other gear) and my system sounded like absolute hot garbage. There was only muddled flat bass. Nothing that punched me in the back or rattled my rear view mirror. I was adding a JL Audio 10" sub and a 2 channel 250-watt amp. I knew the potential for the system to be much better. After listening to my system for a few months (all the while trying to figure out what I could do to make it sound better) I researched this product and finally broke down and bought it. I just finished installation of it (fyi, it does need it's own constant power cable, ground and lead...which i borrowed from the amp connections) and it sounds AWESOME. I used to have my stock head unit on +5 on the bass (out of 6) with the Scoshe and now I have it set to 0 and it absolutely thumps. I'm going to tweak it a bit more but I didn't want to disturb my neighbors in our quiet neighborhood. Trust this post and remember that sometimes you do get what you pay for. $20 vs this price is a lot, but I feel is completely worth it.

Amazing product.

Heard about this product on Hyundai Forums and purchased one for my Sonata GLS. I installed the sub and amp from my previous vehicle and expected a similar sound. I was astounded to find out that I had not even come close to the full potential of my sub and amplifier until I HAD to get a line output converter.

Do your research on line output converters and you'll find some from 15 dollars to 500. The LC2i is super economical for the results. It is worth every penny. If you have a sub and amp direct plugged into RCA outputs from your head unit, UNPLUG IT, buy the LC2i, and run the audio to your sub with this instead. I still cannot believe the results.

OEM Intergration at its finest!

Crutchfield Customer Review (What's this?)
 
When looking at putting subs in my 2006 Chevy Impala LT, I wanted to go with an
aftermarket cd player. However, GM vehicles have these weird harnesses and not
to mention that I have steering wheel controls too. Therefore, I researched line
out converters. I chose Crutchfield because the price was the best :) I bought
this one and was highly skeptical about the whole factory radio and subs. I must
say that I have been pleasantly surprised by this
product. It sounds great in my car alongside my 2 12" Memphis PR subs and 1000
watt amp. I also bought a wired remote (from eBay) for tweaking when a mp3 has
too much or
not enough bass for my liking. Installation seemed simple... I didn't install it
but I observed the process. If you are going to keep your aftermarket radio, I
would definitely recommend this product. You won't be disappointed.

OEM INTEGRATION HAS NEVER BEEN EASIER

Crutchfield Customer Review (What's this?)
 
I have held off on a system upgrade in my 2011 Mustang GT since it was purchased four
months ago. I decided to make the move once I read reviews on the AC LC2i ALOC. I
received it from Crutchfield in two days and had wired up the amp kit in advance so it
was literally plug and play. Two Boston G3 12" subs in a custom enclosure and an
Alpine digital amp, a 1.2 farad cap, and this little guy pushing super clean signal and it
is amazing. I am using the pass through channel to feed a second digital Alpine
powering a set of 1" tweeters mounted in the sail panel. What an easy install and the
end product is phenomenal!!! The Shaker 500 has come alive and it sounds like
thousands of $$$ has been poured into this system. The Accubase feature is flawless,
the incorporated line driver is maximizing my amp's potential, and the augment of much
need bass and high-end support has turned my system into an audiophile's dream!
The Crutchfield team was awesome - as always!

Everyone seems to be purchasing this item to add a sub/amp. I have a 2010 F150 Screw with the Sony system and all i want to do is keep my factory sony bass from rolling off. Is this the product for me? [ Michael  Mar 28, 2014 ]

  • This is a really nice unit. I installed into a BMW 330i because I wanted to add in an older bazooka tube with an older amp I had. The processor keeps the bass appropriately up for the volume range. The end result is the bass is heard with the volume down and it isn't distorting with the volume up. I'm impressed with just how good it made this old gear sound. [ DAVID   Mar 31, 2014 ]

I replaced my factory door speakers, however now I need more power for them to sound good. I want to keep my factory HU and I do not plan on adding a sub. Is this the processor I am looking for when I want to add an amp to my existing sub-free system (factory low power HU and 4 new Polk 6.5" door speakers)? [ Zach  Jan 30, 2014 ]

  • The LC2i should work great in that application. The only drawback is that you will not have a fader. You can install a dual amp balancer or an EQ to to get fade control. [ MITCHELL   Feb 13, 2014 ]
  • Zach, installed this unit in an 08 Avalanche with factory premium Bose/Nav HU. I added an amp and sub to my factory unit using the LC2i. Simply tapped into the factory rear speakers, and powered the amp and sub. The set up gave me what I was looking for without losing the control functions from my factory HU. No regrets on my end. I feel I get most of this stuff, but I do admittedly get stumped with installation and set up at times. I've purchased a few items from the folks at Crutchfield, and their tech support has been great to work with. Don't hesitate to reach out to them... [ DANIEL J   Feb 04, 2014 ]

Ao it says 400 watt rms on it, you can still hook up a 1000 watt amp, right? [ Kyle  Jan 26, 2014 ]

  • I would certainly use it. I think my bass amp is above 500 watts and this unit is excellent. I'm super happy with it. [ DAVID   Jan 27, 2014 ]
  • Hello Kyle, yes you can use this unit with your 1000 watt amp. The 400 watt max. Is referring to the maximum wattage that can be sent into the LC2i from your existing equipment. The output will be low level (pre-amp) . Safe for any type amplifier. Mike [ MIKE F   Jan 27, 2014 ]
I believe that I understand the concept with this device but just wanted to make sure. I want to add an amp/subwoofer to my existing system. The input to lc2i is from the existing right and left speakers. I simply tap into the wires to those speakers and those speakers remain directly connected to the head unit...right? So in other words the lc2i is connected in parallel with the existing speakers? Second question; when properly connected, the existing head unit will control the volume of the existing speakers (obviously) and also control the volume of the newly added subwoofer, right? Thanks. [ MIKE  Jan 06, 2014 ]

  • I am using the unit to supply signal from a factory deck to a 1000w amp and Rockford Fosgate sub box. So the input wires I am using are tied into the same wires powering the stock rear right and left speakers. The existing head unit will still control and volume up and down for all components of the system. There is a gain setting on the LC2i where you can pre-set the drive you want to send the amp and sub. [ MARC L   Jan 20, 2014 ]
  • Yes you are right. It has worked great for me and I still have all of my steering wheel controls. It sounds great. [ SHAUN A   Jan 10, 2014 ]
  • Mike, you are correct with your assumptions and you can also add an additional remote to the LC2i to adjust the bass if necessary . Good luck on your system build. [ OSCAR   Jan 07, 2014 ]
  • Yes everything you said is true. The lc2i will have a gain (bass) adjustment as well. Make good thorough connections and this thing works flawlessly. [ ROBBIE   Jan 06, 2014 ]
  • You are correct you just have to tap in to the existing speaker wires [ DAVID   Jan 06, 2014 ]
  • Yup, you've got It right. It's really seamless and easy once you set the levels (which is painless) and acts like a factory system. For easy bass level adjustability I used an alpine amp with remote knob mounted discreetly on my dash. [ TRAVIS M   Jan 06, 2014 ]

  • I believe you have it correct. Make sure you are tapping the front speakers, in most systems the rear's aren't an ideal source. You'll need to fiddle with the various gain settings to get the sub to blend with the existing system. In my case I was adding two amps, one for the front stage and one for the sub. I cut the wires coming from the factory amp to the front speakers and ran a set of speaker wires back to the LC2i. Ran RCA's to the new amps and then speaker wire back the the existing front speaker wires. This is a very good Hi-Low converter. You can tell it's working hard to reject any noise. Just don't count on the bass restoration feature. It's only effective at adding a muddy bottom to the music. Get a high quality sub-amp like the PDX's and count on the RUX-knob to add and subtract bottom as needed. [ ROBERT   Jan 06, 2014 ]
  • That is correct! Splice into the speaker wires and go directly to the lc2i. And yes, your main volume will control all speakers and subs. Although you only need input from one speaker, not both left and right speakers. I used input from my passenger side rear door speaker. The remote turn on to the amp is located in the " left " input on the lc2i. So I hooked up positive and negative from my speaker into the left input on the lc2 to act as a remote to turn on my amp. For the power and ground for the unit, I simply ran 18gauge wire directly into the power and ground located on my amp. Works flawlessly for 6-8 months now. Hope that helps! [ CODY D   Jan 06, 2014 ]
  • Mike C, I bought one of these and installed it in my 2013 Durango. The answer to your questions is yes. The LC2i gets the signal from your rear speakers and converts it to work as the signal for your amplifier. Your head unit will then control everything from volume to the equalizer. Your existing speakers will work as normal and your amplifier will receive a great signal to power your subwoofer. Kris [ KRISTOPHER   Jan 06, 2014 ]
  • Answers are yes and yes I do suggest you get the remote for it as well though as obviously of you want less or more bass you can control from that instead of head unit it also gives you more flexibility when running [ GABRIEL   Jan 06, 2014 ]
