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.

Was getting alot of distortion from my old Monster FX100 LOC. Bought the LC2i, installed it, and distortion was gone. Great product and the customer service is even better. Called customer service and Erik was great at helping me with the install.

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.

The adjustments control the 2XS signal output to your power amplifiers. The circuitry provides output level control to drive any power amplifier wirh up to 9.5 volts of input signal, which helps achieve maximun signal to noise ratio. Please note: the output of the 2XS is proportional to the input it receives. At aproximatly 5.6v the 2XS the should produce its rated 9.5v of output. Any less input voltage and output will dcrease. Output status leds Power: indicates when the 2XS is turned on, 3 volts: light up when there is 3 volts RMS present at the 2XS output jacks.this is more than enough to drive must amplifiers, so check your amplfier's manual to make sure the amp can handle it. 1 volt: displays when there is 1 volt RMS present at the 2XS output jacks. [ ISRAEL  May 30, 2016 ]
Yes, it needs remote power. I used 12 gauge but you can use 10 ga. All its really doing is converting the speaker wire cable into rca jack cable. [ Derek  Jan 04, 2016 ]
You can hook the remote wire to power antenna on your stereo or two a terminal in your fuse box that only comes on when your vehicle key is in the accessory or on position. You can use as small as 18 gauge wire, I used 14 gauge since that was what I had available. The other power wire needs to be attached using 14 or 12 gauge wire. This is not really an amplifier so you do not need anything larger. If you have to, You can just use one power wire that comes on in the accessory position and use a jumper wire from that power to the remote power. [ Jonathan  Jan 04, 2016 ]
You can if you bridge your 4 channel amp to 2 channel and wire your speaker in parallel to bring them down to 2ohms if they are 4ohms. Remember that you won't have front rear level control just right left. [ jean  Dec 28, 2015 ]
You will lose fader control from front to rear speakers. You only need to get signal from either front or rear speakers, not both. Get the 6 channel, you will have more flexability and be ready for your sub. [ dan  Dec 28, 2015 ]
Basically in my 2009 ToyCam I took the two rear speaker paired wires and connect them to the LC2i inputs, to do this - leave the factory rear speakers connected and splice into them - determine the positive and native leads for each left and right rear speakers by researching your specific vehicle. Connect to the positive line of the left rear using similar type wire (matching gauge [thickness] and strand type) into the input block of the LC2i, repeat the process for the negative feed. Use electrical tape or shrink tubing to cover all exposed bare wires that have lost their insulation or plastic coating. Repeat the process for the right speaker feeds. I have one sub with an amp, which has an RCA type connector feeding the AMP input. Interesting for my SUB install l used a home audio JBL sub which no longer worked because the 110v internal AMP burned out, I determined that it had a 75 max input, so i purchased a JVC 75 watt Amp with a bridged output capability, allowing it to be a mono output, from Cruchfield. I removed the 110v AMP and externally mounted the JVC Amp on the out side of the sub and wired the sub inputs to the mono output on the JVC AMP then connected the JVC mono input line by the RCA patch cord to the output of the LC2i - sounds great!! - hope this helps [ DOUG  Dec 08, 2015 ]

For details on fit or installation please contact an Advisor by phone (1-800-324-9695) or online chat. They will be able to pull up your vehicle and give you the details on if this will fit and what you will need for an installation in your vehicle. [ Krissy  Aug 12, 2015 ]  Staff
No, this does not have a subsonic filter or any crossove built in. The accubass feature is mainly to compensate for the factory systems that cut the lower bass at higher sound levels. This is a high quality piece, I've used it in two installs so far. I would turn off the accubass off, then start tuning your amp after that. [ Juan  Jul 07, 2015 ]
Well lets see here. The LC2i can be used with any amount RMS amp. The 400 watts power handling it is talking about is what can be input into the lc2i. Your stock speakers where you catch the signal will only be putting out about 25-50 watts, so you are good there. All the lc2i is doing is converting signal to rca where your amp can be hooked up to it, but its better than a cheap line out converter because it boosts the volts going to your aftermarket amp. It is great and i highly recommend it. Your amp, (Massive audio?), is only rated at 1200 watts rms at 1ohm, 650 at 2ohm, and 350 at 4ohm. You can never go by peak power, that number is pretty much irrelevant. So you have 3 kicker cvr's in either dual 2ohm or dual 4ohm version. If you have the dual 2ohm, and if they are all wired together correctly, you will have a 3ohm load at the amp. And at 3 ohms your amp is only putting out about 500watts RMS. Your subs are rated up to 400watts RMS each.. So you are only getting about 165 watts to each speaker, thats not going to thump too loud. If they are the dual 4ohm version, then you still only have 2.7ohm load at the amp, which is going to give about 600 watts rms. Thats still only 200 watts to each sub. It honestly would probably thump harder with only 2 subs, depending on which dvc ohm version you have, because you are robbing power from them by adding in a third sub and not having the amp large enough to push all of them efficiently. Check out this link for sub wiring diagram. http://www.crutchfield.com/S-uvMAEvjrghx/learn/learningcenter/car/subwoofers_wiring.html [ CODY D  Mar 07, 2015 ]

Sorry, forgot to include model year. it's a 2011 GMC Sierra EXT [ Tim  Dec 23, 2014 ]
Quite a lot of choices you have listed. I will tell you what I did with mine, and hopefully that will help guide you. I tied off the input to the 6" speakers in the roll bar sound bar, to the inputs of the converter. From there I went to the inputs of a 2 channel / 1000W amp. From there to a Rockford Fosgate sub box with dual 12's. Because of the limited capacity for power that the factory speakers (6) can handle, I left them on the power from the factory deck. Sub hits hard, and highs are good, especially with the factory super tweets. [ MARC L  Dec 18, 2014 ]
I have a JK also and I used the LC2i so I didn't have to remove the receiver. I installed it before 2 amps and 2 12" subs by splicing into the OEM subs wiring. Once set the LC2i let me increase the volume on both amps at the same time. The OEM amp in my JK is good enough for the components so I used the LC2i just for bass. The LC2i is designed just for amp installation with OEM receiver. Once installed use amp per instructions. [ DOUG  Dec 17, 2014 ]
Theoretically you could, but it would be better and easier to just go with the lc6i or lc7i. The lc2i will only provide you with 2 channels/outputs. [ BYRON  Dec 17, 2014 ]
I forwarded your question to an Advisor and they responded with the following: I would not recommend turning a 2-channel line output converter into a 4-channel line output converter via splitters. If you need to hook up more than 2-channels and still need a line output converter then I would recommend this unit by AudioControl. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Dec 01, 2014 ]  Staff
Power and Ground wires, plus a turn on lead and two of your speaker channels from your factory head unit for your inputs and RCA cables to your amp or amps for outputs. [ JOHN J  Nov 21, 2014 ]
i used the lc2i to replace my facoty sub and add a amp. so i just used the leads going into the factory sub itself then from the 2i to the amp then sub. great little piece for what i used it for works very well, but audio control makes great electroincs [ TROY  Nov 16, 2014 ]

More gain to the subwoofer having two remote level adjustments. [ JOHN J  Nov 21, 2014 ]
I believe the remote level knob is to boost frequencies around 35-45 Hz to give a little extra bass. Definitely worth the $30 to add. [ BASIL  Nov 18, 2014 ]
Sounds like you have what you need. The AccuBase control is what corrects the Roll-off. The Remote lead is for the Bass control just like the one on your powered unit and can be optionally installed for those who do not have a remote off their amps. You're better off Tuning this to meet the max threshold your Amp needs, tune your amp, and only use the Amp remote for any quick tweaks. Otherwise, you may not reach full potential since it probably functions similar to a radio Bass setting OR worse yet...it throttles the voltage. Take a meter to it to if still uncertain. [ lyle  Nov 18, 2014 ]
I used the LC2i in a 2014 Subaru Forester. It is connected to the front 2 speaker wires behind the stock radio. I used rca cables to feed a Rockford Fosgate P500X4D 4 channel amp. The front channels of the amp power a pair of Focal 165 KRX2 separate speakers mounted in the stock locations via the factory speaker wiring and the rear channels are bridged to feed a JL Audio CP108LG sub woofer under/behind the drivers seat. Since it was a new car, I paid a local specialty shop to do the install and line the front doors with Rattle Trap FatMat. The sound of a CD in the stock head unit is phenomenal but, this is also a function of the speakers and amp. In this configuration, I mute the rear channels. The LC2I does not add any static or color the sound. I would rate the unit 5 stars. If you are planning to add the LC2i to the rear speakers and expect the head unit to power both the rear speakers and the output of the LC2i, I would expect the rear speakers to have less output. You should use the LC2i to feed an amp which would then power the rear speakers and a sub similar to the setup I used. Hope this helps. The LC2i is a great little unit and I thank those on this site who positively reviewed it. [ MARK  Aug 24, 2014 ]
Ok thanks Jason, I'll be sure to ground it properly. Does this unit require a 12V constant? [ Kyle W  Aug 22, 2014 ]
in my experience with this particular product hooking closer to the speaker did not present any kind of an issue such as static and/or reducing the level from that speaker. I must say this product is very much worth the price, works beautifully. One note i may mention is to make sure you are hooking the lc2i to a non filtered speaker supply, meaning if it is a component style speaker system with a seperate tweeter from the woofer the connection must be made to the full range feed (woofer). I have also found that hooking two speaker inputs to the lc2i that are on the same channel (both left and right from either the front or rear) works best being that certain music notes may not be reproduced on just one side of the cahnel. Hope you find this helpful! [ JOEL B  Aug 22, 2014 ]
I used the LC2i to add 2 - 12" subs and I tapped into my rear left and right speakers and didn't notice that it quieted down my rear speakers. Technically I guess it could have quieted them down but my main concern was being able to keep my factory radio and keeping everything looking clean up front. The bass was pretty amazing. Just make sure you ground everything good and I think you'll be pleased with the LC2i. [ JASON  Aug 22, 2014 ]
As long as you have good connections to your amp, good power wire and good ground, you can tap into the power and ground on your amp. As far as being better than the cheaper versions, I haven't used cheaper but this has output level adjustments which come in handy. You may get a small pop sound when it shuts off your system. For the price it's not a bad LOC. [ BRIAN  Aug 19, 2014 ]
You still have to run a power wire for your amp, so this unit gets its power from the amp. I purchased one of these about a year ago and it was an amazing product until the remote terminal stopped working after a week. What this unit does is give full power after tapping into the line level inputs (speakers). Cheaper LOC's give you a very reduced voltage. this was a Great product till it went bad. I never returned it because the sub box was too big for my trunk anyway. (And I'm lazy. lol) Occasinaly you will get a product that has an issue right after you get it, but it is rare. And from what I hear Crutchfield has amazing customer service if you have an issue, so I would reccoment this product to anyone. Good luck! [ IAN  Aug 19, 2014 ]
There are many place you could tap the 12v too. I would tap it to my fuse box (that has a 12v signal with shut off) like your radio fuse. That way it don't drain your battery once the vehicle is turn off. Or connect it to your amp remote turn on wire. The advantage from the LC2i is, it better quality, Handle high rms from the source your pulling the sounds from, adjustable and it does not get burnt. I did have a schoshe and other brand, they just burnt/fry after a few month due to poor quality that built inside. Can't go wrong with LC2i. Might be expensive compare to other BUT think about it. Would you rather do it once and have a item that last you for years to come or you wanna be cheap and buy junk that last few months and die. That would mean you have to take it apart and waste more time and money that is not worth it. At the end you might pay more then the LC2i. LC2i is a great investment!!! Buy it!!! -Son [ Son  Aug 18, 2014 ]
I initially tried to add an amp and sub to factory headunit. Without a LOC, it just didn't get enough signal to make the sub sound good at all. Then I did a lot of research and got the audiocontrol LOC. What a huge improvement! You'll need to research how to tap into your 12v- google search through forums. This LOC is far superior to those cheap ones. This one can do so much more with ensuring level base sound at all volumes and is very adjustable. I wouldn't even consider the cheap alternative. [ DAVID  Aug 18, 2014 ]
Any ignition-tied 12v source will work (only want it on when the car/radio is on). A good place for power is the factory radio power supply. That way, if you have a system where the radio stays on until you open a door, the LOC will remain active. The main benefit of this particular LOC is its power handling (400 watts). This is very helpful when trying to tap off a signal from a factory-amplified subwoofer. Most LOCs cannot handle the higher power the factory amp will put out. Some would ask why they can't just tap off the signal BEFORE the factory amp. In some cases you can, but in others, the volume for the subs is modulated by the amp. So if you were to make the connection pre-factory-amplifier, the sub's volume may not adjust with the system volume. [ JULI  Aug 18, 2014 ]
I had a difficult time with that product. I never got it to work properly. I kept getting a ground loop noise until I took it out of my system all together and used the high level inputs that came on my amp [ DAREN  Aug 18, 2014 ]

Your adjusting the bass of your factory speakers if you get the remote you will have more adjusting capablity [ GABRIEL  Aug 17, 2014 ]
It would, I would suggest you turn the bass setting lower for the speakers inside and then use this unit to make sure you are still getting all the low end notes, if you want to keep the same tuning for notes but want to adjust the power of your subs I would highly recommend a remote for your sub amp also. [ Craig  Aug 17, 2014 ]
This is a good product for what you need. It will handle the low freq for the sub and keep your interior speakers playing the upper range freq. hope that helps. [ REGINALD  Aug 17, 2014 ]
Is your amp turned to LPF?. There should be a switch on your sub amp that says something like LPF/HPF. Needs to be switched to LPF. If you are getting music through the subs, not just bass, you probably need to adjust your amp. This unit helps boost the signal going to the amp and gives the sub more clean power than just a regular cheap line out converter. This unit is only used with the stock radio. Your stock radio will still control tuning on all speakers, including the sub. But you can set the bass higher with the lc2i, and pretty much turn the bass all the way off on your headunit.

The inline converter listed here takes your high output factory deck and steps down the output to clear the signal up before sending it to an amp. I bought this to use with my Jeep Wrangler factory deck, and am using a 1000W amp to a Rockford Fosgate sub box. I am very satisfied with it's performance and would recommend it to you. [ MARC L  Jul 17, 2014 ]
If you want to keep all factory controls functioning as they are and if you want a better/ cleaner signal to amp/ pre-amp, use the line converter. Additionally, some factory head units deliver substandard bass signals to protect cheap speakers (on some models). Again, if you want a solid bass response, the LC2i does the job. I paired this with a powered sub and factory head unit from Chrysler (MyGig RER) and it sounded great. Really can't go wrong for $100. [ MARK  Jul 15, 2014 ]
Yes you need it while utilizing the factory head unit because your factory head unit doesn't have the pre amp output the LCi2 does [ GABRIEL  Jul 15, 2014 ]
I forwarded your question to an Advisor and they responded with the following: If you choose to bypass the GTO circuit, you will need to run a switched lead to the Remote In terminal. I would recommend a constant circuit be used for the + 12 V terminal. This is how it would have been wired in the "good old days", before head units had a turn on lead. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat. [ Krissy  Jun 13, 2014 ]  Staff
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 ]

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 ]

yes you can [ Derek  Jan 04, 2016 ]
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 ]
Yes. You are spot on. [ MARK  Jul 15, 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 ]
