PERFECT Car Audio Sound! JL Audio's Signal Processors EXPLAINED!

[@eblkheart]

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.

Car audio has now become Rock It Science!.... I was an old school installer and then got into auto upholstery...(now I'm an x ray tech) All kinds of listening needed with hands on kind of work environment.... I feel so undereducated in this stuff now! Haha!

[@408SPLKINGS]

Thank you Sir for all your videos audio tutorial commentary demo editing & lessons taught. Your channel is such an underrated & useful valuable tool

[@sardal1930]

I have the twk 88 and it helped clean up my sound so much. I highly recommend it for any aftermarket system

[@CarAudioFabrication]

Thanks for sharing 👍

[@cardsin2005]

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!

[@silverevans7763]

Did you go active and after a year how has the twk88 been working for you

[@gregroles69]

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.

[@Gunny559]

I seriously was jus looking for a video like this and here it is! Seriously your timing was perfect 😮

[@zacharyhalterman]

Same here! Didn’t want to go with audio control but there wasn’t really any good vids on JLs line. Then boom!

[@riderreviews3737]

I've been waiting for this video for a long long time. Recently bought the twk88 and running my kicker cx360.4, jl audio 600/6 v2, and ct sounds 2000.1d with it. Sounds amazing

[@Beavy]

I replaced an ageing audison bit one with a twk d8 thanks to your recommendation and couldn’t be happier. Thank you!

[@Mad21X]

I have the 86 paired to the 88 feeding a rd 1500/1 and xd 800/8 the audio is amazing

[@themodifiedlife2774]

I’m thinking of running the same thing

[@Grayback1973]

I love me some JL Audio! For the money it is the best as far as I'm concerned.They have been making high quality audio gear for decades now and it seems they just keep improving!

[@joshuahebert7405]

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.

[@BruhMan_5]

Ive had the fix and twk for almost 10 years and never got them tuned. I should get that done

[@orhunokcu8660]

Great video. However, I think a dsp with both high level and low level input could be made.It's definitely a marketing strategy.

[@djparra41]

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??

[@djparra41]

If this isn’t possible what is the actual function of the feature? And how you best utilize it?

[@davect01]

I wish I had known about this kind of LOC before I spliced and diced in the one I have

[@ronmerkus5941]

Imagine using a 2 channel head unit into a twk 88 , and then configuring the DSP to output all 8 channels, now Imagine that type of stereo setup in your car !!!

[@theaaronimal]

Wow, this is such a great breakdown. Thank you!

[@marko6394]

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]

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]

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.

[@canadoescalling1800]

Can a Fix and or Twk help correct all pass filters in newer Toyota systems? Love to reuse my JL equipment but not sure how best to combat these pesky all pass filters. Thanks for all the great content 👍 👍

[@robertdelgado5236]

Excellent video

[@jasonerosewrx]

@CarAudioFabrication can you do a video on limiters and how to set them. have searched everywhere and can't find anything. If not a video can you explain? Love the vids, keep it up!!

[@mikejuarez6989]

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 ?

[@frankpaul3204]

Mark , do any of these devices restore the attenuated bass from oem headunits ?

[@jacksondavid8758]

great content. Is the Twk 88 and the DSP in the MVI/VXI amps the same? I ask as I have several good amps and it would be much cheaper to incopropate a twk as opposed to converting to mvi/vxi's

[@JBOsurf]

Is there a multichannel amp on the market that also does what the Fix and Twk do, so everything is in one unit? I just want to plug one thing into my factory system and run new speakers in the factory locations. Does the new Alpine Optim8 do all this including flatten factory eq?

[@shakenfake]

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?

[@bfytw2125]

Love my TWK88.

[@silverevans7763]

[@bfytw2125]

@@silverevans7763 actually had it more like 4 years. Still a great dsp option

[@georgeb7050]

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?

[@j0hn22]

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]

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

[@j0hn22]

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

[@girthquake9655]

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.

[@shawnsanderson3695]

The resembles Audio Control products.

[@williambasiege4355]

I have a 15 Mercedes GL550 which is good for changing the digital signal to analog I have JL HD amps

[@squibcakes74]

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.

[@OscyJack-]

Question. I was going to buy a TWK88 off diymo, can I just use a t harness and correct the factory EQ via TuN? Or is it recommended to have a fix in front of it. Thank you!

[@ATALETN]

Which one of these would you recommend for a 2022 Honda accord? Am doing a upgrade and have amps and preamps but need a good output converter.

[@Gunny559]

I’m have a new Rav4 Hybrid with the JBL upgrade. I’m bringing over my three JL TW3 subwoofer&amp. Which LOC do you recommend for me? I don’t want an audio shop to up sell me. Been enjoying your videos for years!

[@gingeroutdoors6254]

I need your help to design my sub box! I am want to run dual 12s and dual 15s on the same box.

[@antoniogaxiola4569]

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.

[@themodifiedlife2774]

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]

I would also like to know this!

[@prky009]

Which is better JL TWK 88 or Alphine PXE 0850 X if I could get both under the same price

[@derekhallett6946]

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]

A Fix 86 I would think.

[@dabloesco]

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

[@hotjesssica954]

Do any of them. Use. Bluetooth. To be able to tune. From phone with an app?

[@seancarignan4387]

If I want to run the audio through a Bluetooth controller and run a 5 channel amp - which DSP is best?

[@cliffordsawyer2994]

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?

better, low input, or high input ?

[@MikeInNorCal]

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

[@CarAudioFabrication]

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.

You can expand via the pass through optical to add as many as needed.

@CarAudioFabrication does the dsp software recognize additional modules as a channel continuation or a separate. Meaning if I have 2 modules does it display channels 1-16 or would you have to separate groups of 8?
