Line Output Converter Explained - How to Install & Features to look for!

When installing an aftermarket amplifier for subwoofers or speakers for a car audio system that you are keeping the factory radio, you need a way to take the speaker level signal from the vehicle and convert it to an RCA line level (low level) signal. The device that allows you to do this is called a Line Output Converter, or LOC. But do you need an active LOC, or passive? And what features do different LOC's have? How do you install a line output converter? Let's take a look!

Good info here! I used the Kicker KISLOC2 (2-channel line-out converter) for a number of years before getting the AudioControl LC2i Pro. The Kicker LOC does a nice job at doing what it designed for, but there is nothing to customize/tweek for your specific audio setup and needs. But at $15, the Kicker KISLOC2 is great if you need a no frills LOC. The AudioControl LOC's are definitely worth it though.. no regrets there!

[@user-kq6oi3yi8w]

Thank you. I’ve been looking for how to turn my amp off with it and your the only video to help

[@jamesthomson6304]

This has been really helpful. I just purchased a new car and love the head unit. And was dreading the idea of trying to replace it to put my subs in and had no idea how these worked.

[@evilinside5984]

For subwoofers, i suggest Audio Controls Epicenter micro, comes with a 2 in 1 Bass knob, the inner knob controls Total Bass volume, and the outer knob controls the amount of Bass restoration you want to add to music that hass little to no bass= this can add it! Its also an active line out converter!

[@khayreejoseph333]

Great stuff here. Thanks for the info. Now I have a question. Can you use the LC2 to run more than 1 aftermarket amp? Like a midrange amp and a sub amp? Can you use both main outputs and sub outputs at the same time?

[@stevenrulz225]

Hey mark ! When running the 4 wires for the R and L from the factory radio to my trunk. What is the best wire to use here ? I ran 16 gauge but then realized I could of just chopped an rca . Thank you !

Hi, I love your content and I’m about to start two project cars. For me it’s going to be the whole deal (DSP, two amps, etc). For my wife’s car I was wondering about adding a small kenwood active subwoofer, it already comes with the speaker signal input, would you recommend using the AudioControl LC2 Pro to feed the sub instead of going straight from the speaker wires? I mean, it’s a powered sunflower from a reputable brand. Thanks in advance

Super helpful information, helped me get the right gear that I needed for my truck. Thank you. Was looking at the epicenter to draw signal from my factory radio to my sub amp. Is that an active LOC as well?

[@evilinside5984]

Yes, they are active. I recommend the Epicenter micro, because its the only epicenter that you can turn off their Pfm= blocks low freq. ( most AC products with the Pfm is factory set to start cutting bass @ 33Hz, the micros Pfm, when set to on= 25Hz, but with the Pfm switch set to off=10Hz before it cuts bass output), and comes with a 2 in 1, ACR4 bass knob= inner knob controls total Bass volume, and the outer knob controls the amount of Bass restoration you want to add!

[@Verse914]

Is it possible to use the factory subwoofer wires to the LOC? I was hoping to replace the stock sub for an aftermarket amp/sub. I would only have one set of wires to connect to the LOC, so wasnt sure if that would be an issue.

[@tonka518]

Can i use this to get my factory sub signal and also get full range signal and if so which side do I put the sub signal and full signal? I would be using a mono block amp for sub signal and 4 channel amp for front and rear speakers. Also would I just splice into the front and rear speaker wires to run them to the 4 channel amp? So I would end up with 4 sets of spliced speaker wires

[@leinistavarez3715]

I have a 2017 Honda pilot elite , I’m planning to upgrade all the speakers to JL c2 and components to the front plus I want to install a 4 channels amplifier to run them and I will like to have the option that I want to add an aftermarket subwoofer later I could . The question I have is which converter do I need the LC2i , LC2i pro , LC6i , LC7i or LC8i ?

Do you have to run from the head unit or can you run off the back speakers 6x9 speaker leads?

I remember when i could just wired everything to my head unit and be on my way now that i have a newer car i have to figure how to get factory signals ugh. Thanks mazda for doing bose systems makes things difficult

[@SinisterScoundrel6562]

Some aftermarket head units are low voltage, and can only be tuned with an amplifier to a degree so there's no clipping signals. LOCs can boost that volume level to high and clear without any clips in the signals.

[@cptklutch26]

I'm hoping that's what's wrong with my system I barely get to the point where it sounds good and it's clipping. I hope this LC2i helps out with that so I can get more voltage to my amp.

[@evilinside5984]

@@cptklutch26 You have the Lc2i, not the pro? The Lc2i, has a built in Pfm= 33Hz bass cut off, so if you want lower Hz than that, get the Lc2i Pro= 20Hz, or better yet, the Best Loc for Bass, by Audio Control, in my opinion= the Epicenter micro, has a switch to turn OFF the pfm= goes down to 10Hz, has Bass restoration, plus comes with a ACR4 Bass knob= 2 Knobs in 1= inner Knob controls total output/volume of bass, and the outer Knob controls how much bass restoration you want to add( best to use bass restoration for music that has little to No bass present).Either of these Ac Locs can boost the output voltage very high if needed, up to 9.5volts of clean output! 99% of the time 4 to 5 volts is the most RCA output voltage you will ever need/want!

[@jimmytwotimes3048]

So what do you need a line output converter for a vehicle that already has a factory subwoofer? Or can I just splice and input those to my aftermarket amp?

I don't have room behind my headunit where I have my current loc. Would I be able to wire one of these under my driver side seat? Or would that be too far from the source unit?

This is going to sound stupid but I have a 2015 Durango RT with the Beats system in it. Looking to replace all the speakers with more powerful ones and same with the sub. Given that there are signal wires for the tweeters, mids and sub, should I buying 3 LOCs? Additionally, there are currently 9 speakers + 1 sub in the truck. I'm looking to add 2 tweeters and two mids to the mix. Should I be running 3 amps? Again, just here to learn

[@jman4573]

I wanna run a 4channel for door speakers and a mono block for subwoofer. Do I get a lc7i? Or what do you suggest.

[@Charley_Buehner]

So, with AudioControl being such an important long-term sponsor, do you get a little more "one-on-one" with the company compared to the rest of the world? Maybe connections to someone who can answer "when" (not 'if' LOL) they'll re-introduce a version of the ESP-2 and/or ESP-3? And maybe replacement controllers for the original models? The ESP and Epicenter have always been, and in my opinion at least, will always be among the most iconic processors in the mobile audio industry. They've milked the Epicenter for decades while leaving the ESPs bleeding out in a shallow grave. Any chance you've got ties to someone who can bring 'em back to life for us?

[@Dicklefart]

So if I were to run the remote wire to the amp, that will act as the remote for the amp to turn on and I don’t have to run a wire to the front? Or does that remote signal turn the loc on?

I believe that it should be fairly easy give it already has factory sub, No?

Question if I bought the epicenter micro do I also need to purchase a lc2i pro to deal with the stock audio roll off or can epicenter micro deal with both the roll off and bass enhancement?

The Epicenter micro, with the Bass restoration, can compensate for bass roll off, and even adds bass that was not there by sampling freq. above the cutoff of Bass notes. Also has a 2 into 1 Bass knob, outer Knob is for Amount of Bass Restoration, inner Knob is for Total Subwoofer Volume= Awesome, plus its an active line out converter!

[@bsegment]

Not sure if this will get a response but.... I have a 2019 Subaru that I've installed new door speakers with amplifier, subwoofer with an amplifier, and a plug-and-play android head unit replacement (replaces the entire center console area and retains all factory features). I enjoy the head unit, and the door speakers are loud and clear. But the subwoofer leaves much to be desired. I had this amp/sub setup in a prior vehicle so I know this side of things isn't to blame. The issue I'm having is the sub output is nearly non-existent at low volume levels, and then jumps to nearly max output at the top 10% of the head unit volume. One issue I see is the subwoofer output is a single RCA but the front channel is dual. I was wondering if I switched to a line output converter like this, if it might take care of this issue? Or if you had any other checks or suggestions?

[@johnvargo8050]

Hey just discovered your channel, great content! I know AudioControl is a sponsor, but do you have an opinion on the LC2i vs. the less expensive JL Audio LOC-22?

[@1maanarmy]

I use a DQ61 and I get an echo on the rear channel when I added a second mid and high amplifier for the back doors. Any ideas? There was no echo when I used a 4 channel amp using front and rear rca’s from the DQ61. Also when I use the pass through the front amp to the rear amp there is no echo. Only when I use the rear channel separate on the dq61 to a separate amplifier. Thanx.

[@CarAudioFabrication]

Because there is delay somewhere in the signal chain. Try using the same signal for front and rear. You will lose fade capability but everything will at least be in time. Or go all out and get a DSP so you can time correct all speakers.

[@jaylanwallace3257]

Will this work on a mono block amp if I just wanted to add subs

[@IzzYChannel]

Hello! I have myself a 2 door VW Mk5 Golf so I'm tapping into the rear 2 woofers(speakers) for signal for the Subwoofer AMP and I have a question... for the REMOTE IN where's best to actually get it from? Since I'm doing pretty much everything in the back of the car, even the battery... I wouldn't really want to go to the headunit with a wire for it. I have the regular LC2i. Thank you in advance!

[@BradyPetersonXXvXX]

I tapped into my center console cigarette lighter positive to get mine. Fuseboxes also work just make sure that whatever positive you're using is off when the car is off. Using a source that is active even with car off/key out will work to turn the amp on but will obviously keep the amp running until the battery voltage goes below minimum voltage for amp. Also, make sure that the positive has enough voltage for your needs...typically, you'll have enough power to turn on 1or 2 amps/devices via remote in using a 12 v positive.

[@vsolcarv]

But can you splice the wires so you can feed both the speaker and the converter.. or for example, if you just want to add subs do you have to sacrifice two speakers because you can not splice ?

Yes, you can but I recommend removing the rear speakers so you get more bass I side through those 2 holes and upgrade your door speakers.

[@tapig3322]

So if I understand this correctly, to remedy the roll off we use the threshold knob but this only affects the same music type it was tested on right? Some songs have stronger bass that will trigger it earlier in my experience

[@CarAudioFabrication]

In which case you would simply reduce the bass with an attached ACR knob.

[@tapig3322]

@@CarAudioFabrication I've also read from someone that you can maximize the threshold and turn down the amp gain but I haven't tried that yet.

[@googah.qq1]

​@@tapig3322using modern hu's for music usually sucks if there is a bass hpf on the outputs, best approach is getting an amp with a dsp or a dsp that has at least 2ch's with summing ability and a basic cheap loc to get the navigation sounds vice versa from the hu then sum those navigation and other hu sounds in -12db and use the other source of the dsp or an dsp'ed amp to stream music directly from your phone or a dac/player. bringing the bass back with the whatever algorithm these "bass bringer's" may give off unintended signals and simply act stupid, also although controlling the bass with a knob for each song is kinda ok its still not practical, especially if you want songs to play as the engineer intended.

This is a great question! The technical/most expensive answer is yes, they= Ac would recommend both. But do you REALLY need both= i dont really think so, here is why? The Epicenter micro has Bass restoration built in= it takes a sample of the full range freq. responce, and adds in freq. that either are not present, or are very weak, and increases the output by the amount you choose with included ACR4 (2) into 1 Bass Knob.( inner Knob= Total subwoofer Volume control, and the outer Knob= Amount of Bass Restoration you want to add!). Plus the micro is the only Epicenter with A Pfm you can switch off! Pfm on starts limiting Bass output @ 25Hz, and with Pfm set to off= 10Hz!

I have a couple of questions Mark , by using the right and left channel from the rear speakers do you piggy back off the speakers or lose the speakers in place of the amplifier? I ask due to signal degrading and it's effectively changing the ohm's? Obviously losing the speakers to fit an amp for a sub is not ideal would a 4 channel be best as to run the rears off 2 channels then bridge the others for the sub? Cheers

If I tap into rear speakers to get a signal for a subwoofer amp, how do I maintain a signal to the factory speakers from the point at which I connect the LOC?

[@ratherbeboyz4485]

I plan on doing the same thing. From what I’ve read it shouldn’t effect the rear door speakers but I haven’t tried it

[@evilinside5984]

You just splice= (cut back the speaker wire shielding, twist a new wire around the speaker wire, then soldier, and or use electrical tape around exposed wires), do this to both rear speakers, and run the spliced in new wires to the line out converter.

Hi, Can the LC7 convert bass output using speaker input that has bass filtered out? The rear speakers in my car is easiest to access and would like to use that to tap into my LC7 to plug into my underseat subwoofer with built in amp. I first had it setup without LC7 into the high level input subwoofer amp and it sounded terrible.

[@gavinhelms7581]

My lc2i pro’s maximized light does not come on no matter what level the bass output is set at, I only have one speaker input to the lc2i so I wasn’t sure if that was the issue or something else is going on that someone might know about.

[@evilinside5984]

You need both left and right speaker inputs. But you can just tap into those rear wires, you dont have to disconnect them from your speakers= just cut the speaker sheath/cover, twist a wire around your speaker wire( then soldier, and or @ least put electrical tape around the exsposed wires), and run it to the Line out converter.

I am installing an LOC in my Yukon and I am confused about how to set the output levels of the LOC. I know that the gain on an amp is supposed to be set to the same level of the RCA preamp output voltage, but an LOC effectively creates its own RCA output from speaker levels, and not all head units have the same output levels. I am using an aftermarket pioneer CD player(from 2005, lol) which has 4 volt RCA outputs, all being used currently, and am adding the LOC to the rear speaker outputs of the CD player to gain an additional subwoofer output. I am doing so because I am assuming that if I were to use Y adapters to split the sub output RCAs to 2 amps, it would effectively cut the output voltage the amps would see from 4 volts with one amp to 2 volts each with 2 amps. If that is not the case and amps see 4 volts regardless of splitting the signal, I would not need the LOC after all. Please advise.

Hi! Do I have to keep the factory amp or remove it?

[@evilinside5984]

Keep factory amp.

Hello. Can you help me? I have active subwoofer alpine SWE-815 but I want to install adapter low high because I don't have rca out in my factory Radio. Can I do this? Thanks

[@malaysiaairlinesflight3706]

Stupid question i suppose, but i bought an 80s vehicle and a buddy if mine suggested an LOC to remove the necessity to hook the 12v hookup to my battery so i dont have to go through the firewall. Is this a true statement for an LOC?

So I was recently told that there is loss of fidelity due to taking a low level signal, amplifying that, using the converter to bring it back down, so that it can be re-amplified. How much weight does this hold? No, I don't know what the suggestion for an alternative was yet.

[@brandonjohnson131]

It definitely holds some weight but most wouldn't notice the difference. The preferred alternative is a 4V or higher signal from the head unit directly to the amplifier, which is why he noted the caveat of people needing to keep their integrated units (stereo, nav, engine diagnostics, etc.) Since that is usually the case with newer cars, many go this route to retain the stock functionality of the multifunction unit while upgrading the amplifiers and speakers alone.

[@benpatterson5081]

@@brandonjohnson131 so the key is finding the wiring for the preamified signal from the factory stereo?

[@brandonjohnson131]

@@benpatterson5081 Yes, but good luck as that could be like finding the proverbial "needle in a haystack". Most OEM's don't use RCA outputs, instead opting for complicated wiring junctions to route signals. Like I said, most people cannot detect any sonic loss of fidelity from using a high quality LOC so you're probably good to use one if you want to wire in an aftermarket amp.

[@evilinside5984]

This is why you buy a Quality, Active Line output converter like this Audio Control unit. It will convert the factory high level signal, to a Quality RCA output signal( that can be adjusted to up to 9.5Volts of clean RCA output Voltage) for your aftermarket Amplifier! By the way, most aftermarket amps wont need/want more than 4 to 5 Volts of RCA output voltage.

What do you mean= plug n play amp? How DID you have your Lc2i hooked up, prior to your "plug n play amp? We have to know what you changed from before, to after, to know what to look for.

[@evilinside5984]

@@shaddyemelu8723 When you say head unit, is there a separate factory speaker wire output, or is that the same speaker wire, connected to the now powered, plug, and play, speaker amp combo? If its not separate, your new amplifier, may exceed the input voltage, that the Audio Control LOC, can handle, causing your distortion/unclean sound?
