When installing an aftermarket car audio system you will need a way to interface between your source unit and your aftermarket amplifiers. When integrating into a factory system with either a factory head unit or amplifier there is often times issues that need to be dealt with like factory EQ and time delay. Additionally if you want to to be able to tune your audio system it is best to add a processor which allows you to do so in the signal path.
JL Audio's LoC, FiX, and TwK products are great for addressing these challenges, but what does each one do, and which is best for you? Let's discuss the LoC-22, FiX-82, FiX-86, TwK-D8 & TwK-88!

I use a twk88 in my 2019 Dodge Challenger. I never knew how much I was missing until I had this installed. It's makes angels sing. Seriously. I send a digital line to it from my factory head unit (from my pac) to my twk88. That unit then sends to my JL Audio RD900/5. This works perfectly after running the TuN software. Get one if you're questioning it. You will NOT regret it.

@cardsin2005 Год назад

Massive improvement in tuning quality with the twk88. I used a MiniDSP before, but tuning was a nightmare with REW. A lot of the heavy lifting was done by the JL's TUN software. It is truly amazing, and JL was nice enough to allow anyone to use it for FREE!

@gregroles69 7 месяцев назад

Before you get your heart set on this setup, make sure your country has all parts available, I'm in Australia and JL Aust has never imported a D8 nor were in a rush to do so. Given they aren't that popular, I had to look far and wide and spend a bomb to get one from the USA, given I'd already bought a local 82 and was committed by then....also a further caveat is that the FIX works ONLY at the volume you calibrate it at, some people report the factory volume works ok, but realise the idea is you set it and then ONLY use the remote knob for true linear volume, there's no guarantee the factory volume will work correctly anymore.

I used to have a Fix86, before I knew about PAC Amp Pro, mated to a Twk88. The sound summing, especially up top, is much cleaner on the PAC Pro than I ever could get it on the Fix86. The PAC also has a wire harness that let's to clip straight into your factory infotainment center rather than cutting up all of your factory speaker wires. I know they don't have one for every vehicle but I HIGHLY recommend it mated to a Twk88. Would love to see your thoughts on the PAC Pro CAF.

thanks for video. explained way better than jl's video's on there web site. so buy fix or a new head unit? then the twk. I have a ford focus upgraded sony package . i bought jl's rca's for each chanels and splice in after the factory amp. i have front c2 components and c2 6x9 there way and a jl10w7 enclosure .jd1000 and jd 400/4. I feel like I can't tune the sub just right. bass only sounds good at a quarter volume. and the mids/high drowned the bass at higher volumes, which is where i like it. what do you recommend ? do I need a head unit or fix and twk or more sub's lol?

@jacksondavid8758 7 месяцев назад

If I have this correct. My 2020 Silverado only really needs a LOC-22 since my simple setup im going for would only be an aftermarket amp for a front stage and amp for a subwoofer ?

@marko6394 Год назад

My 2011 Acura TL has a factory amplifier with separate front, rear, center, and subwoofer inputs and outputs. However, I found that the front channel input signal is a full range. It doesn't make sense to me why there would be separate inputs if they aren't crossed over prior to reaching the amplifier.

@JonathanDFielding 10 месяцев назад

I've never understood why would anyone ever buy the TwkD8 for $500, when you can buy the Twk88 for $50 more, which is way more flexible and future proof by adding the extra 8 channel inputs! I've got the Twk88 and it's awesome! I use abQualcom Apt-X HD Bluetooth puck via optical digital audio so technically could get by with a TwkD8, but previous setups used the analog input, like when I want to connect to the stereo for some reason instead of streaming Spotify over my phone

@gregroles69 9 месяцев назад

For me it was space and a cleaner install, pairing a Fix 82 with a D8 with just a short optical cable. Optical cables also make the power lines easier to run around them as they are not going to interfere. I've never seen a fader as necessary, apart from when I had young kids and they might have been asleep.

@shakenfake 7 месяцев назад

What “OEM system” are you highlighting? I have an 06 Sierra with Bose and I believe that is what you are using. I want to keep the stock head unit because I believe it keeps the vehicle original. It seems like the Fix 86 and the TWK88 would be perfect to do the job. I was under the impression the stock Bose system the front speakers and tweeters were on the same line. Is that true?

@cliffordsawyer2994 Год назад

I have a 16 ram 1500 with the alpine system im confused between this jlloc22 and the LC2I/PRO... The only difference i see is this plays waaaaaaay lower to 3hz? And the LC21/PRO stop at 30hz and 20hz? both will correct my bass roll off though correct?

@antoniogaxiola4569 3 месяца назад

What happen if I use a Audison Bit One Dsp and the output voltage for Amps are below 1 volt, So I try up the gain from Dsp to 0 dB and is the same thing. My question is, should I add a LOC before my DSP? I have a Mazda 3 2017 without BOSE.

@dabloesco 9 месяцев назад

Ok so im just trying to understand if this is basically only for cars that have not had their factory head unit replaced with a assumably high-quality unit with high band EQ settings and yes I know not as good as a dedicated device, but low pass filter, high Pass filter, etc. I’ve always thought it was only for having the ability to adjust say a tweeter versus the mid range of component system or something. Are there any other benefits that will be noticeable to someone who has high band EQ 5 V output, time alignment, and a bunch of other features I haven’t used really. I’ve been considering buying a AC unit Trying to research If it’s going to be more benefit than what I’ve already dumped into this full replacement system

@ceavalencia4767 Год назад

@squibcakes74 3 месяца назад

The fix 86 can work fine without the extra remote volume control? Seems pointless to add this if the calibration goes out as soon as the driver adjust the factory HU volume… I really want to get this but adding a remote volume kinda defeats the purpose of maintaining the factory controls.

@djparra41 4 месяца назад

If the Fix82 has an Input Clipping Detection than why can’t we use that to find out the max volume from the stock head unit while playing the test tone??

I got rid of my audio control for a JL loc and the sound was night and day. I spent hours with my audio control trying to tune it and the bass didn't sound right. I switched over to JL loc and it took a few minutes to set the gain and the bass was more punchy and low. I'll never go buy another audio control product.

@derekhallett6946 10 месяцев назад

Need some advice, current car is a Tesla X with the UHFS system, although i'm only running 8 speakers, 3 way active in the front, coaxial in the rear doors and an aftermarket subwoofer. Amps are VX800/8i for the speakers and XD600x1v2 for the subwoofer. In trying to run a wired DAC as an auxillary, I took up inputs 7/8, however I believe since the Tesla head unit is limiting the bands to each channel, I need to sum the frequencies first so I can redistribute them at the VXi back out to the appropriate channels. I also want to control the XD amp signal so when I switch to a different preset (running my DAC), that I can still control my sub. Right now the sub is on an LCi1. Any advice?

@gregroles69 9 месяцев назад

A Fix 86 I would think.

@themodifiedlife2774 8 месяцев назад

So can the fix 86 work just with a subwoofer amp? Basically a temporary loc? I know it’s made for a full system integration but I plan to just start with a sub system with my factory bose then eventually do a full Bose replacement but found a good deal on a fix 86 now

@lazytechguyltg 6 месяцев назад

I would also like to know this!

@j0hn22 Год назад

I have a 2021 Mercedes-Sprinter with only two channels out (Front L/R) and I'm planning a system going to the vx700/5i. Mercedes' stock system is super basic and obviously won't require the summing of the FiX 82, but it's unclear to me if the input signal is heavily tuned by the OEM, or relatively flat. Considering how little thought they put into the factory sound, I wouldn't be surprised if it's not even tuned for the 99-cent speakers in the doors. That would render this FiX 82 unnecessary. According to JL, OEM "digital-domain corrections can vary from subtle to dramatic, depending on the amount of equalization engineered into the factory audio system." Is there anyway to know? Or do I need to install in TuN to know (and then possibly return the FiX 82)? Another options is to get a simpler, far cheaper Kicker 47KEYLOC, which will just ensure an equalized signal is sent to the VXi amp. This doesn't have multiple channel summing of inputs (which I don't need since the Sprinter only has Front L/R), and doesn't have time alignment fixes, but would Mercedes have introduced time delay to front L/R channels? Maybe... the L/R Fronts are installed with the 49-cent tweeter separate, so would they really have time delayed the mids versus the highs? Who knows? Only person I can think of is Mark...

@derekhallett6946 10 месяцев назад

Did you ever come to a conclusion on this? Im wondering the same thing for my Tesla X.

@j0hn22 10 месяцев назад

Sorry, no. I put the project on hold and installed an Atmos system in my house with an Integra 8.4 (7 surrounds.4 ceilings.2 subs) instead. I did conclude to just go ahead and buy and install the JL Audio FiX 82 since I'll be ripping the whole interior apart, and it's likely Mercedes just loaded a factory tune from another model, so I'd guarantee a clean signal before tuning it again with the JX700-5i. I figure it'd be best to match JL-Audio w/ JL-Audio.@@derekhallett6946

@MikeInNorCal Год назад

If my aftermarket stereo has 3 rca outputs do i need to run 3 sets to the amp or just one set?

@CarAudioFabrication Год назад

Depends. Usually 3 sets would be front, rear, sub. There will be controls on the head unit like fade that change front and rear level, and subwoofer settings on head unit that impact subwoofer output. But you could just use the front signal for instance, and in software of something like a TwK break that signal out into different outputs. Really depends on the application.
