Introduction to AudioControl's LC2i "what is and how to use AccuBass"

[@Grizzleback07]

You guys just saved me hours of headache trying to get this to work better. I totally forgot to adjust the threshold and was getting pissed my DSP was sounding like crap when it wasn't even getting a good signal to begin with.

[@aang6421]

What DSP are you rolling? Curious on the setup, instead of just running everything into the DSP.

[@markg5916]

To this day this is the best explanation of this devices function on KZbin.

[@goldberg34]

Always love your guys' content. My trusted local installer suggested the LC2i when I wanted to add a subwoofer + amp to my 2014 Mercedes E350, instead of a cheap LOC. He tapped into the premium Harman Kardon subwoofer to the LC2i, giving signal to an old Alpine mono amp powering an old Alpine 12" in a sealed box. Long story short, it sounded awesome. I was most impressed of how this setup played ultra-low bass notes. Currently, I transplanted the LC2i, alpine sub & amp to a 2019 Rav4, non-JBL system. The same installer tapped the front speakers to the LC2i. For the most part, the bass hits very hard. The downside is, it doesn't play the same ultra-low bass from the same tracks compared to when the system was in the Mercedes. I'm wondering why this is the case? My Rav4 has the OEM stereo/speakers, so there is no factory amp, and I doubt the OEM speakers have passive crossovers or bass-blockers. I also add that the OEM radio does not decrease bass signal as the volume is turned up, which is what AccuBass is for. I suspect that the OEM radio was designed to cut down ultra-low frequencies at all volumes to save the OEM speakers. What are your guys' thoughts?

[@jcwilliamsii33]

I am having problems with car audio system installation. I have a 2015 Dodge Journey R/T. It has a stock Premium Alpine Audio System. 6 speakers 1 subwoofer. I have an AudioControl LC2i LOC tapped into the stock subwoofer. I have the GTO in the bypass position, as I am using a toggle switch to turn everything on and off manually. Tuning the LC2i is fairly straightforward. Your KZbin videos helped with that. My issue is with tuning my amplifier and subwoofers. I have an Alpine MRV-M1200 Monoblock Amplifier powering 2 Alpine DVC 2 ohm + 2 ohm SWS12D2 Subwoofers (trying to power anyway) wired in series parallel to 2 ohm final impedance. Correct me if I'm wrong on the wiring terminology. The RCA wiring is driving me crazy. When hooking them up I barley get any bass. Even after adjusting the Gain and Bass EQ. When only one RCA is hooked up I get better sound. Do I need both RCA's hooked up. I also noticed in your video you only had the one RCA hooked up when demonstrating the tuning process. I also don't know anything about the Low Pass Filter or where it should be set at. Thanks for your time

[@jokezpaine3408]

hey where's is the stock sub in the 2015 Dodge journey rt.

[@pedroc6823]

1-If you only connected to one side of the input of the LC2i only one side out will work, Use a y connector out to your amp. I have found in most cases the thresh hold was off or turned all the way left counter clock wise. The Thresh hold was intended as a place for the accubass to start. I turned it all the way Right so its always on and adjust bass on top and accubass to my taste. I used my amplifier out from my stock sub woofer to the LC2i also, I connect the HL to the left side and used wire jumpers to the right side.to feed both RCA out. I just thought it looked better.

Great video and informative about what the threshold does on the accubass but you gotta make sure maximized isn't blinking because that means you're clipping

[@pedrorubio950]

Yes ! now I can remove my amps built in high to low to this !thank you

[@pearlwsz7]

Fernando what such a huge help.

[@poxcr]

I installed a JBL BassPro SL2 powered subwoofer on my 2016 Volkswagen e-Golf (non Fender audio) by tapping the front speaker outputs and connecting them directly to the sub’s high level input. I noticed the head unit output now clips at a much lower volume and it gets unusually hot. It is impossible to set the sub amp gain as the levels are all over the place and slight changes to the amp gain cause the sub to cut in and out. I verified the polarity of all connections on both ends and everything seems alright. I would assume tapping into the speaker outputs effectively lowers the impedance seen by the head unit onboard amp causing it to go crazy. Wondering if using an LC2i instead of the sub’s high level inputs would make any difference.

[@nibelungvalesti]

So..what do I keep my amplifier gain levels at while tuning my lc2i? Should I let me lc2i handle gain levels and not worry about amp tunes?

[@pedroc6823]

That is the intent of the unit. at one point I fixed amps and found that some amps Volume all the way down was like having it off. barley have the gain on the amp turned, at most not more than 1/4 turn or less. But some amps cant handle the voltage of the LC2i so it may need to be turned down a bit. Mine is set to about 9 Oclock.

[@vonjose888]

You guys are fantastic. I'm reviving my old system from high school and putting it into one of my daily drivers after years & years. 02 Chrysler 300M. JL12W7, JL 500/1 &...stock deck...yes I know. But its the RB1 NAV & its gorgeous. Anyways. I have the LC2i & the M's have 12 speakers in 9 locations or w/e it is wonderful Infinity system with a ~366watt OEM amp. *My Question is* can I splice into the wires on the OEM amp's wiring harness to run my LC2i? I'd sort this out myself but I realized at 1AM I had broke my big inline fuseblock for the power wire many years ago removing the system from the original 300M. -_- lol so its a "tomorrow thing".

[@tmright18]

@@FiveStarCarStereoInc I like that 500 RWS @ 4 ohm amplifier that has this built into it more. It's a monoblock though.

[@adamwaselich7315]

If you are using the remote gain knob for the Lc2i instead of one on the amp- where do you set it while tuning? All the way up?

[@adamwaselich7315]

Solitionwas: turn the remote gain to max. Then max out the threshold adjustment on the side then adjust the accubass knob on the top to your liking.

[@LTSRIDE24]

Or unplug the knob.

[@YouEsseNetworks]

Can the main output and bass output put out the same bass levels so if I were to put two amps in with their own subwoofer on each they’ll have the exact same sound? I don’t want one sub to have deeper harder hitting bass than the other but I do want each amp to have their own set of channels instead of splitting the rcas between the two amps.

[@pedroc6823]

Accubass and thresh hold only works on the bass out put.

[@dunnoyolo2238]

So didn't CT Sounds basically copy this with there CT-LC2 ?

[@MrWalterbanks]

Hi Dean and Fernando, Thanks all the valuable knowledge you share. I have a PioneerGM-9605 5 channel amp on order. Would I gain anything in audio quality with an Audio ControlLC7i over the built in speaker level inputs of the Pioneer? Going in a 2017 F150 XLT, no Sony, no nav. Standard audio. Infinity Reference components and a Pioneer 10” shallow mount sub enclosure also coming. Thanks, Walt

[@luanpham989]

I have the exact question... I do have a LC2i don't know if I should get the LC7 or just use the LC2i since I have it and take advantage of the input functions on the Pioneer GM-D9605 . Thanks

[@purepetroleumjellly]

any updates? did you pull the trigger and get the LC7i? or just stick with the built in loc on the 5 channel amp?

[@MLProductions.1]

What's you end up doing I'm going through the same thing on a 1500watt Rms Memphis amp. I already bought this just in case I'll probably test both out and if high level input sounds as good or better I'll return it

[@Nahyoutrippin]

Great videos as always. Question? I have a 2015 Mercedes C class w/Burmester system. I tapped from the subwoofer outs to the LC2. During the setup, I turn everything down on the lc2, can't get it to light the maximize(or clip) when the volume is increased. Any reason for that?

[@bumpylump9236]

Did you figure this out why it didn't clip? My guess is you reached the lc2i max signal. This is good news tho, you can now go full tilt on volume, just adjust your amps down a bit. Acu bass you turn right under half and turn screw on side down. Then turn radio up.....way up like 85% turn bass knob to like 25%, now turn little screw real slow. This os when the magic happen. Your little clip light. If you turn this little screw too far you can send a too strong signal to amp. Amps has voltage input limit. Look that up and don't go past that.

[@PhilGoode]

@2:42 so, it's a preventative measure by manufactures to keep from blowing out the factory speakers?

[@FiveStarCarStereoInc]

Yes, they don't want to replace subs all day. It is just one of the many problems you run into when interfacing with a factory radios. Keep in mind not all manufacturers do this, some actually just use better equipment.

[@tonyzeno2715]

Question for you guys.. I have a vehicle that had a Factory subwoofer, I have since added a component sub with a 300 watt amp and I have an LC2i which is getting the input signal from the Factory Subwoofer Wire/output. Now i have the accubase threshold turned all the way up and if i keep the Accubase knob and the Bass knob both at the 12 o clock position as a starting point this sub is banging like crazy I have to turn the gain on the amp barely up?? Is this correct or should I lower the Bass knob completely and turn the amp gain up?? I havent been able to find a good starting point for the LC2i when its getting an actual factory sub signal as opposed to it usually a full range signal.

[@joek1980]

Hey guys thanks for the great vid as always! I have a 2017 Wrangler with the factory Alpine subwoofer in the trunk floor. I want to add an aftermarket sub and amp. Do I connect the factory subwoofer’s speaker wires to the LC2i’s input?

[@FiveStarCarStereoInc]

Yes that or get the PAC Audio Amp-Pro for a true Pre-Amp output

[@micahpoole9699]

Five Star Car Stereo do I need to have speaker wires to the lc2i from 2 different speakers and can it be any speakers

[@coeyoejones7339]

I have one question...i have a 8" bass sub. Do i wre the lci2 to the factory sub or factory 6x9. For better sound to my 12's

[@OxaudioPhilly]

Coe Yoe Jones the correct answer is to have the tools such as an rta to see which driver plays your sub frequencies. However if your 8” is a true subwoofer that should be the driver you are after, unless your 6x9’s play full range 20hz-20khz and you are using the lc2 to provide signal to more than a sub amp. Really depends on vehicle and how its set up, but your best bet with no test equipment is to grab signal from the 8”.

[@LTSRIDE24]

Sub for sure! Especially, given the fact that it's more than likely located right next to where you're going to mount your AudioControl

[@Grayback1973]

So in a 2018 Terrain with non-Bose I want to use a PAC LP7-4. I am adding a 4 channel amp for doors and a mono amp for subwoofer.I plan on sending the 4 factory high level signals into the PAC for the 4 channel amp and then just using the RCA output plugs on that amp to feed the mono amp.Will the mono amp be starved for low frequency because of the factory bass rolloff? Is the LP7-4 a bad choice for what I want to do?

[@nickdemattia4875]

your better option would be the Audio Control DQ-61 .Key Features : Signal Delay: Because of speaker placement limitations and the seating positions in a car, it is almost always the case that the driver of the vehicle is in an incorrect acoustic alignment. This exists because the driver is close to the left side speakers and further away from the right side speakers. Thus, the sound from the left side arrives much sooner than the right side. By delaying the appropriate speakers for just a few milliseconds, the DQ-61 is able to allow the signal to arrive at the same time putting the driver in perfect acoustical alignment. AccuBASS: To protect OEM speakers, car manufactures often limit the bass frequencies at higher volumes. AudioControl has developed a patent pending circuit called AccuBASS circuit to compensate for this factory roll-off. The AccuBASS circuit automatically engages at a preset volume level and reverses the factory bass roll-off to give you the music the way the artist intended it to be heard. Speaker Level Inputs with Selectable Summing: The DQ-61 is equipped with six high-impedance speaker level inputs that allow it to accept amplified signals from any factory installed amplifier, even Bose. Unlike an inexpensive passive line output converter, the DQ-61 offers the highest possible sound quality and performance . Equalization for Maximum Control and Performance: Like all of AudioControl's high performance signal processors, the DQ-61 is designed to offer maximum audio performance and control. All six output channels are equipped with highly accurate graphic equalization filters. This equalization allows for the taming of the most demanding car acoustical challenges or correction of factory radio response curves.

So I doubt you even check this but I’m gonna try... So... I have a 2012 Chrysler 300 SRT8 with the HK 19 speaker factory system. Here’s my dilemma... I used the LC2i tapped into the factory sub and add a monoblock sub amp, my custom fit box with two 10 but can’t figure out which one I dial in first the amp or the LC2i and more importantly HOW do you do it? That would be a great video as I see many people asking and answers all over the place. PLEASE HELP

[@dcole302]

Same question. Did you get any help?

[@faction95]

Another excellent video Five Star Car Stereo! On the LC2i, do the Sub outputs put out a full frequency or just the lower sub frequencies? I'm trying to figure out if I can use the LC2i or if I have to get the LC7i. I currently have a 4 channel LOC that the rear channels pass through my sub amp to the rear channels on my 4 channel amp. Also, will AccuBASS restore the bass frequencies that my stock head unit seems to filter out around 35hz and lower at all volume levels?

[@FiveStarCarStereoInc]

+FACTION95 the bass channel is only for bass. It will only fix bass roll off as the volume goes up. It is not an EQ so it can not fix the DE-EQ problems of the factory radio. For that we use the LCQ-1

[@faction95]

Thank you so much! You guys rock! When are you going to open a store in Southern California?

[@FiveStarCarStereoInc]

+FACTION95 haha, it is a nice place

[@patsjoholm]

Can the lc2i show when the head unit is clipping or does that need a different device to test with?

[@Jose-ew6hj]

Okay for the main output how to I connect a 4 channel amp to it. My amp has 1-4 rca inputs but lc2i has 1 rca output

[@sublovelows]

I was wondering if this increases voltage once you have already set your amplifiers voltage. Would you have to readjust the amp voltage to the increase in acu bass?

[@jaydavis226]

When adjusting bass for sub in video you switch phonic to sub outputs. What happens to the mid outputs? Are those being adjusted as well. Is there a switch to adjust each outputs separately? I don’t want to have a sub, subbing and my mids distorted. Thanks in advance

Hey guys I’ve got a quick question, I’ve got a 2018 Honda Accord Sport and the factory head unit cannot be replaced so what I did was pay for a professional installer to install all of my high end JL audio aftermarket component speakers which are JL’s C3-650 with crossovers , two in the front and two in the rear deck and a JL 10Wv3-2 in a boxed which sits in my trunk. To control the power from my amp and to control the volume of the bass sub the installer installed a JL-DRC-205 Digital Dial Rotary controller with integrated push button & LED Indicator. Next they installed a JL FIX- 86 OEM Integration DSP. And last a JL RD 900/5 900W 5-Channel Amplifier. I’m happy with the sound of the system I cannot fade from front to back or from left to right The alignment on my screen on the head unit, the dot Hass to be right in the middle of the car for the front and the back to play simultaneously but you cannot fade from right speakers to left speakers from front speakers to back speakers, I cannot do that.

[@pedroc6823]

yes it can they have two different roles. The Lc2i is mainly a line driver with bass boost. and the epicenter is a bass restoration unit that can let you restore a certain frequency and how wide from a center frequency. I can see this creating pretty bad clipping if not done right. If your amp has a bass boost like a 45hz, set up the LC2i first and add a bit of bass boost at that amp frequency. I always see this unit with all the settings set up too high almost 90% of the time.

Thank you. You can tap into the factory wiring leaving the radio to play the factory speakers. The AudioControl can then go to give the aftermarket amp signal.

If I’m thinking about this correctly, the front factory amp just carries a remote turn on and speaker level outputs to the sub (it doesn’t amplify the sub), so is it even worth it to use the lc2i from the front factory amp to the new JBL sub, or should I just bypass the speaker level outputs from the factory amp, and instead use rca cables from the 5v pre-out in the Kenwood head unit to the JBL sub? I’m not sure, but I don’t think it matters if I bypass the factory amp (and ditch the lc2i), because the subwoofer isn’t amplified from there anyway. Am I correct in thinking this way, or in my case, is there still a benefit in using the lc2i?

[@zopound7688]

Need advice, so I recently had 2 10’s installed, a bass amp, lc2i, and an extra battery to my 16 challenger 8.4 inch factory radio. The issue I’m having is that my two front door speakers seem to only have bass coming out of them, while the dash and rear speakers I can hear more clearly. Did the installer do something wrong? Because I want to hear sound other than bass coming from my two front door speakers. Please help with advice.

[@steelydan8421]

Nice video, as always. Question, can the LC2i be used with the Kicker Key 200.4 and a CX600.1? While still utilizing all of the Key tuning features? TIA

[@flightmedic7169]

I have a question. I know this has a control knob but my amp has one too. Do I have to install both or how does that work? Thanks

[@archiesanson6871]

do i need to disconnect the lc2i from my after market amplifier before applying one of the option? I'm leaning towards the option 2 as i can't determine if I am losing base when I turn the volume up. i have 2016 accord touring. please let me know. thanks.

[@dfiggs915]

Great information, I had a question you stated that when using 40hz tone to set bass level the maximize light should not turn on. But it's ok for it to come on and off when playing music. Is that correct ? Just wanted to make sure

[@iiishception]

When the light comes on means there is distortion. For certain subs they have tolerance for such. I have kicker comp c and tuned my gain to where the light comes on every 2-3 seconds. Mostly when there's a kick in the beat. The thing with distortion is that it's a form of DC current while speakers take AC. The voice coil in the subs is supposed to go back and forth. Too much distortion and it gets stuck in one position or the other which heats up the voice coil and detaches it from the speaker which is known as a blown speaker. So the point is that the light is distortion, but don't be worried just figure out if your subs is a quality brand that can take it. The light coming on every second or 2 second isn't anything that can damage it as it's not receiving DC current fully. Now if the light was on solid then that's something to worry about.

[@mfrancis706]

Another great video guys, most informative. 3 questions please... Is there any difference in the LC2i and the LC2i Black, other than the colour? As I wish to utilise the remote turn on feature, should I also be fusing the power into the LC2i? You said the Acu base is almost like a "reverse base boost eq" my question is, If I tap of one of the 8" stock underseat subwoofers, to this LOC which will be connected to 2 12" subs. will the Acu base also restore the base curve to the 8" stock subs, as it it conected to the 12" subs? Hope you can understand what i'm trying to describe... Marcus.

[@FiveStarCarStereoInc]

M Henry thank you. No difference just color. We just use the power coming from the amp, so there is no long run of power if you are going to run a power wire to the battery put a fuse at the battery. No it will not help the factory subs. They are before the LC output so the can not be helped.

[@Bassrob1983]

Hey there so I don't have bass roll off so I turn threshold all the way up.. so what do i put bass on.. I notice my amp clipping a bit too soon so I'm assuming too much voltage from lc2i .. my lc2i accubass is half my main is off and bass is half.. gain on amp is half and premature clipping..

[@pedroc6823]

The bass adjustment setting acts like the input voltage or volume on your amplifier. They should have labeled it volume. if you have it too high and your amp too high of course it will clip. if you play a tone and have at least your radio 3/4 up adjust the bass/volume until the clipping indicator comes on, back it off until it goes off. Your volume of your amplifier should be almost off or all the way down. The unit is providing all the input voltage you need. Warning some amps cant handle such an input. . FYI, My small amplifier could not handle such a voltage of almost 9 volts. I ended up setting the bass volume at around 8-9 oclock. The main is only for additional speakers or amplifier , though it does improve bass also and the main adjustment is for the same purpose but for the main output only. if you are not using additional speakers it plays no role. So if you are clipping lower the volume on your amp, or if it cant handle the voltage of the LC2i reduce the bass /Volume to about 8 O clock and at most adjust your bass amp 1/4 of the way not half. One or the other could be up but not both. Good luck.

[@ryanlilly1427]

I want to add 2 amps to my Nissan Frontier, one for a subwoofer and one for my door speakers. Is the LC2i the line output I want or would the LC7i a better choice?

[@FiveStarCarStereoInc]

If you like front and rear fade get the 7 if not go with the 2

Thanks for this video guys. Between the LC2i and LC7i which would suit me better? Stock Wrangler headunit, 4 PolkDBs, Stealthbox JL Sub, everything to a AlpinePDX amp.....THX!!!

[@FiveStarCarStereoInc]

If it is the basic factory stereo the lc2i will work unless you want fader. If it is the premium factory stereo you will need the lc7i for the summing capabilities.

[@dcole302]

I have a couple of questions. I have a monoblock amp that I'm using to hook up my subs. Do I need to plug the remote out on the lc2 to the remote input on the amp? I'm confused by the remote in and remote out on the LC2. Also, is it recommended I splice into my rear 6X9's or would it make more sense to splice into my factory sub? Since I'm adding a monoblock and only want bass signal...

[@FiveStarCarStereoInc]

The LC's remote out is there to turn on the amp if your radio does not have a turn on. You do not have to connect the LC's in to anything. Yes connect to your factory sub

[@jeffreycompton]

What frequency signals do you get out of the MAIN outputs? What frequency is the BASS output playing, I see it run 33 - 10k total, but I want to know if there is any separation

[@chrisvantuyl5554]

Hello. If I'm only adding a single subwoofer.. would I need this or the lc1i? Or use this and just tap into both rear speakers or just one speaker?

Little warning.. as you increase the threshold there is a slight delay in response to that setting.. make small changes and wait.

[@FiveStarCarStereoInc]

Auus Worrior it is ok if it is not coming on. It just means the LC is not clipping. If the gain on you amp is set right you are getting all the power. There is a balance between the LC and the amp. If one is down the other is up and vice versa

[@FiveStarCarStereoInc]

Shaun Russ if you are using the LC2I you will just connect the front left and right output only. If you want front and rear you will need the lc7i.

[@yankphan100]

Does the lc2i need both left and right input if I’m adding solely a subwoofer amp ? Can I grab signal say from my right rear speaker or do I need both left and right ? Thank you for a reply.

[@pedroc6823]

in your case you do not need both left and right as long as you at least use the left because it triggers the GTO. it will come into play if you fade to one side only. But you can use a Y connector to your cables any way.

You can use the Lc for what you are trying to do just fine. There is no way to turn off the AccuBass, but you can use it as a bass EQ. It can be very helpful if used correctly.

Hi 5 star. I have a 1998 Lexus gs300 w Nakamichi Premium sound. I am going to buy a Lc2i. I just want to add a 15 in the trunk and amp. This Lexus has a factory 10 in the trunk lid. My BIG question is. Do I tap before factory amp or after. Like should I tap into my factory amp harness that goes directly to factory sub(or just tap into sub) or should I tap into factory head unit? Thank you and any one elses comments would be greatly appreciated!!!!... Also my factory sub is single voice coil, if tapping the sub is a good idea, do I just "y" the two positives and two negatives...Im telling this car is so hard to upgrade because it has this dam Nakamichi premium system, no harnesses for aftermaket Head unit or any parts....lol...........Nick

[@FiveStarCarStereoInc]

You can tap at sub or amp, just has to be after amp either will work fine.Y the sub wire into both inputs.

[@nicholasfisher2729]

Thank you for the reply. Ok so after factory amp. So tapping in at factory head unit harness(before factory amp) to receive a FULL RANGE SIGNAL is not the way to go? I believe the stock sub does not have full range signal. Would this work for the EPICENTER PLUS as well?
