JL Audio DSP Fix 82 and Fix 86 Tutorial and Review!!!! 

That's my Prius that Matt is showcasing and I will say that the system he installed is incredible - what a difference. The best part is the sound, including the subwoofer does not over-power the environment of the car, or the ears of any passenger - just pure, clean beautifully EQd music. Thanks Matt!

If only more customers could see just how jacked up the factory eq curves are they would understand why these units cost so much money. good video man

This is one of the best car audio videos I've seen. Thorough, clear, and easy to understand. Thanks.

I need one of these for the Honda. It would be absolutely perfect. I love that you showed us the difference in frequency response. Thanks, dude.

Just put the TWK88 in my vehicle and love how easy and user intuitive it is. Great video Matt.

I'm curious about what the FiX does on the Loudness compensation filters. For those who don't know, this is a volume dependent EQ (usually set around 80 Hz and 10 kHz) which compensates the lack of bass/treble that we feel at low volume levels (higher boost at low levels than high levels). If you make the FiX calibration at 3/4 of the volume, the Loudness should already be disabled. I guess, if the FiX doesn't monitor other volume levels during the calibration process, the Loudness is maintained - which can be a good thing in most cases.

Top notch! Good video...love the RTA before and after.

Very informative video. You've really explained in detail some of the concerns I have with my install. I recently sold my 2011 F150 that had Focal ISS570 5x7 components in the front and Infinity Kappa coaxials for rear fill all Driven by a Hifonincs Brutus 4 channel amp. Pioneer shallow and a D8601 for bass and full Hushmat and baffle install. It sounded GREAT! But I didn't have any factory integration even with my Sync OS. Fast forward, just bought a new 2017 F150 and thought I would invest in some nicer equipment. Unfortunately I rushed ahead, as my friend had recommended a FIX82 and I jumped on board without doing much research. So I purchased one along with a pair of Hertz Mille 165.3 Components and some Gladen Alpha 165 coaxials, retaining the Pioneer shallow 12" and pairing everything to a Hertz HDP5 5 channel amp. I really had high hopes. My installer did a decent enough job but they did some damage to my paint and I won't be returning to them. Don't feel like asking for their help any further. The first thing I noticed was the loss of my fade/balance. When I try to adjust, I can never truly isolate one door without getting sound from the other, whether it be front or back. Isolating a side isn't a problem. The Mille's also sound completely anemic and under powered, or maybe unrefined would be a better way to put it. Definitely not the air moving mids I expected from a Hertz set. The Gladen's on the other hand fill the rear pretty well. They also draw a 3ohm load so that might explain the contrast. Any ideas/suggestions? I really thought this setup would be performing better. Do you think the FIX 82 is the right piece for my setup or should I make the switch to the 86, or a different product altogether? Thanks in advance. New subscriber here! -J

Just got this thing, will put it in front of my dsp and amps which I can't get to sound right (vw polo 2018 oem HU). Crossing fingers. A bummer I had to purchase the usb cable, thought they could put it in the box for this price!

Wow this is great information for us audio lovers i seen thise and never understood why they existed im also installing a fix86 and a twk88 on my stick radio thank tou for your information very dtailed cant wait for more im sunscriving hopefully you keep making them great videos not just a click n bait switch

Great Video Matt. Thank you, this helped me decide to get the Fix86.

Thanks for the video and all the information. I'm try to learn about tuning car audio for sq. This helps a lot

Great video, really like how you walk through everything (clear, simple, knowledgeable). I've subscribed! Did you ever do such a video with the Twk?

good lookin out..thx

Just curious, you told that you need 1 preset for oem head unit and another preset to run bluetooth through the Astell and Kern. Ive got a FIIO M11 which got the coaxial output and a dsp with coaxial input. For now, I play songs through dsp directly to my dsp with a preset. With digital coaxial input, can I use same preset or I need to do another one ? Awesome install 👏🏻😍

Hello, can I use the Fix 86 with ARC Black Bird amp with built in DSP? Thanks👍

great job with your explanation

Good information about DSP.

Glad I found this video. Thanks so much for making this video. I will be getting this processor soon

Question ... my the lights on the left side goes amber after awhile if i go back and recalibrate it they turn green then at some point goes back to amber any reason it keeps doing that

Was hoping you'd of shown the wiring.

My one issue with the fix is that the eq adjustments is limited in power and let's be honest no one really wants flat sound. Because of this you need a twk 88, now you're up to $1100

Great video! It answered all my question but one. Do I need a DRC-205? Some reviews say it's a must but I'm not sure. I do not have a sub, just 4 aftermarket front and rear speakers and amp. Thanks.

Why do you need the TwK 88 for time alignment when the Fix 86 supposedly corrects this during calibration?

Great explanation!

JL amplifier i own they have enclosed DSP Why I been suggested to use it. What equipment you use for tuning? Thanks

I have 2017 Acura TLX V6 Base. It has an OEM Factory Amp. I'm updating car 4 speakers, 2 tweeters, Subwoofer and Amp. I use JL Fix82. Do I run from Factory Amp to JL Fix82 to New Amp? Also when doing calibration, what volume I should set to? The max headunit vol is 40. Thank you

Hi, good video. Helped me with my install. One question, in the TUN software, what are the output settings for when using the Fix86? There are 3 settings where you can change the output voltage (Front, Rear & sub). It defaults to 1.0V. When would it be necessary to adjust these settings?

Is the only benefit of the 86 vs the 82 the ability to keep oem fader control because of its six output rca channels (Front/Rear, L/R) vs two (L/R) of the 82? Or does the digital output of the 82 able to keep fader control as well?

Good video homie!

If I had the fix86 going to a JL 900/5 would I get the DRC 100/200 to adjust level input/bass. Or would it be better to get the HD-RLC?

So what do you do if you have a factory three way system in the front seeing that it only has four inputs for the front? In such as case 6 inputs are needed for the front to get a full range system. Also, many systems today does not even have a cd player. What then?

So are you taking the post Fix signal through a mic in the car or making an XLR to RCA adapter? Also what does an RTA go for now days?

Not sure if anyone will read this or assist. I've had to order a replacement DSP and needs calibrating again. I have a JL audio amp like the one in the video and need to know what values I need to set them? I've tweaked them around in the past and wondered if I need to dial all of them at minimum similar to the video showing in 9:16 and do the calibration from there?

Great video. Do you turn down the gains on the amp before you tune the 86 ?

Would it be worth using this with a stock '22 sprinter with the MBUX system?

Hello Mr Schaefer I was wondering what kind of audio cable do you use when installing a portable player and does it plug into the unbalanced or balanced receptacle in the top of the player. I currently have a AK SE180 player and looking to hook it up to a dsp

What happened when the Toyota has a factory JBL system? Thank you.

So is the goal to have a flat signal sent to your amp then speakers, or do you want to tune the now flat signal with a twk/dsp after and send that to the amp then speakers?

Question? Do I have to get the signal from the factory stereo before the factory amp or it’s better to get the signal after the factory amp?

Question for you. On the old cleansweep unit you could always here when the DSP kicked in at certain volume levels. is the new clean signal on the fix always the same or does the new flat signal change at different volume levels? Is that maybe also dependant on what the factory set up does at different volume levels. Some factory units will drop out the base at higher levels but have more bass at lower levels. what has been your experience with this.

Hello, Great video, I have a 2016 Honda Civic and I'm trying to upgrade the sound system but I must keep the OEM head unit, William this JL audio fix will a better choice than the AudioControl LC2i? my problem is I'm on a budget... I know the LC2i won't help with curve but will it keep up with the bass at higher levels? any suggestions? thanks for the help.

Why most installers still require you to install Audiocontrol LCQ1 or DQ-61, is there a problem with the JL Fix 86, i've spoken to at least half a dozen of these guys, different stores too. I'm sensing they're lazy to move forward and embrace the new tech. A couple of those stores are JL Audio Authorized dealers too and they refer you to a non-authorized dealers and they charge so much, the worst thing is they don't want you to touch their setting after they set your EQ, plus they say that they're saving you money but they're labor to install is astronomical, example to install a Fix 86 cost almost $500 with the unit, which they order from their source, if you bought it somewhere they trick you and they say it's no good and they'll sell you their product saying there's a lot of noise coming from these units, One of the LCQ1 that was installed in my car got so warm that it shut my sub off so they messed around with the jumpers and ran the system into a whole system, it sounded bad at front with the highs so fatiguing and the rears so boomy, it lost the dynamics and coherency of the whole system, I'm running Audiofrog G60S front and rear with a JL Audio XD 700/5v2, and a JL sub, you think I should get the Fix 86 and install it myself, you spend so much and read up on certain products then you'll just be bummed because the installer says it's no good.

Matt, thanks for the informative video. Is there an app or way to adjust the EQ with the FIX unit?

Local dude represent!

Is the fix 86 active? And I have component speakers front and rear on the standard ford/sony head unit will 6 channels be enough?

I currently run a Clean Sweep, are there any advantages/disadvantages to changing it out for a Fix 86?

im looking to buy a DSP im stuck with my oem HU. i have purchased aftermarket componentss(alpine type R 6-1/2) should i buy fix 86 or audison bit 10 D??

There are 12 track in the calibrate CD, do I need to wait until all 12 are done or just do track #1 Fix calibrate?

How do I calibrate if my oem bed unit doesn't have a cd player?

Great video 👍👍....Quick question though....Are the functionality of the steering wheel controls retained?....TY

350$ Its great and all that but i got the same "FIX" using the LC7i. its not quit idiot proof like the JL product but if u can use an RTA it works just as well. I can also adjust the bass with the knob they supply for half the price.

Great video Matt. I recently upgraded my Toyota Tundra crapy Entune factory sound system with all Image Dynamics package. Two ID 10 woofers, two sets of IDQ65CS, and I 5800 Amplifier using the cheap Mloc 740 convertor ($25). Very disappointed ! sound is not clear and rear speakers are very weak and passenger rear speaker is louder than the driver side, at this point i had it check out by a pro and was told that i have a great system, but shitty convertor, so i ordered Fix 86, do you think that would play a big role in sound clarity and quality ?? Thanks in advance !

Does this also allow EQ on the output like an Audio control LCQ?

What do you like jl fix 86 or audiocontrol lc7i?

Hi, if I didn't care about fade (I've never used it in my life) would the 82 be sufficient for a simple sub amp and 4 channel install? I understand it only has two outputs but a simple splitter would solve that.

If I was only adding an amp/sub, would it be a good idea to use something like this?

Hey Matt, help me out here. I am an old school (mid 90s) IASCA competitor. I understand wanting extended control over the peaks and dips in a system but a flat curve doesn't sound good to most people. I ran 2 banks of AudioControl EQLs, 1 set for the listening tests and a second set flat for RTA, and would bypass one or the other. The flat EQ wasn't thrilling to listen to. This doesn't seem like a great default process. Also, were there upgraded speakers in the Prius? You only mention the amp.

since this seperates front, back, and sub outputs, does that mean it does crossovers? if it does, what are the crossover points?

Hey what do you use if your car doesn’t have a CD option and does this make you retain all your factory functions like steering control and all

In my old car, installing an aftermarket head unit resulted in a large improvement in sound, even with the stock speakers and sub. Would installing just the FiX 82/86 be the equivalent of that?

Is this better than the Audio Control DQ61

Ok so I have a question. I want to upgrade my sound system with keeping the factory radio of course. Does this mean that I have to buy the fix 86 just to flat out the signal and then also buy the twk 88 to be able adjust everything??? Or did I understand wrong? Does the twk 88 let flat out the signal and let u adjust it all in one?

How would you run the software if your system does not support CD/DVD drive? Would it work to transfer to thumb drive and install via USB port?

Currently have a Bit Ten but seems outdated now, do you think this will work well if not better than the Bit Ten? (car is a 2016 Mazda 3)

how does this work with stock HU's that have base roll off? and after it flattens the signal coming into it can you then run pinknoise through your HU and fine tune the EQ?

What if the vehicle (2017 Chevy Cruze) does not have a cd player?

What about this vs audio control ?

MY DSP Fix 82 has no sound coming to speakers, and the top left bubble is flashing green. Any suggestions?

Does the fix 86 act as an LOC?

Need some help please. I have a 2017 f150 with a fix 86 in it. The installer didn't give me the CD program that came with the fix. I am missing the mid bass big time. I would like to reprogram it by pushing the button for 5 seconds. But what test tone or sound do I use? Just a regular radio station work? Thank you.

curious, what if your car doesn't have a cd player? My 17 Corolla IM is a double dine but has no CD.

Can you hear a difference?

how the heck can that little car support that amp?... larry

I need someone that can calibrate my fix86 and my slash amps here in LA

Will it fix the low volume noise in my ford sync?

Do you still use a LOC?

Ata at absolute electronix thinks this is garbage and hates them. But, if you would see what they did to my car recently, you would understand why you should never take your car there or listen to his advice

Not a pro at all but that's one flat signal. I've been looking at the German Match pp86 definitly more money.

why not just buy a proper headunit
