To build a high-quality sound system, start with a clean slate
You want to upgrade the sound system in your car with new speakers and amps but without replacing the factory radio. However, your factory system uses unusual EQ curves and preset time alignments that work well with the cheap factory speakers, but will prevent your aftermarket gear from reaching top performance. JL Audio's FiX 82 digital signal processor removes the factory system's equalization, crossover filtering, and time alignment, providing you with a completely flat and focused audio signal that your aftermarket amplifiers and processors can turn into high-fidelity music.
Integrates into almost any system
The FiX 82 was designed to get its input signals from your vehicle's speaker wiring — no outboard level-matching devices are necessary. The FiX 82 automatically re-synchronizes any signals that have been time-delayed, returning precision to the sound. It takes your system's 2-way, 3-way, or 4-way outputs, matches their levels, and combines them into two full-range stereo signals. Then dual 1/3-octave equalizers automatically flatten the frequency response, leaving the system ready for your custom processing and amplification.
Digital features and calibration
It doesn't come much easier than this: pop the calibration CD or loaded thumb drive into your receiver, hit play, push in and hold the FiX 82 calibration button, and all the processing is done in about 30 seconds. The 24-bit 48 KHz digital processor ensures clean, low-noise signal handling and output. In addition to the standard analog RCA outputs, a digital optical output lets you connect to compatible devices with the highest fidelity possible.
Add customized tuning via PC
You can plug your laptop running JL Audio's TüN™ software into your FiX 82 to visualize and correct the system's frequency response. The graphic displays the response curve before and after the FiX 82's corrections. The 10-band graphic equalizers on the output channels let you fine-tune the sound to fit your car's acoustics and your musical tastes. The TüN software helps when you're setting up your FiX 82, giving you direct control over its factory calibration processing and allowing you to correct the polarity of any of the inputs.
Optional remote for volume control
You'll set up your FiX 82 with the factory radio's volume control at 3/4 full. Once the system is calibrated, you can use the optional DRC-100 Digital Remote Controller (sold separately) to control your system's level while maintaining the processor's EQ restoration. You can still use your radio's volume control without a DRC-100, but the factory volume-dependent equalization will affect the tone at different settings.
In addition to volume control, the DRC-100 features a Handsfree Optimization Mode that disables the FiX 82's time-correction and adds a high-pass filter to the audio to clarify the sound when making hands-free phone calls. A multi-colored LED on the remote report the operational status of the FiX 82, so you'll know what's going on from the driver's seat.
Important Note: Some factory radios and amplifiers will not work without sensing that its speakers are connected to their outputs. If you don't have output from your factory system after installing this FiX processor, you'll need a FiX-LSA-4 load-sensing adaptor (sold separately) to correct the issue.

This is an awesome "black box" that does exactly what it promises. 10th gen civic Si's will cut the bass pretty drastically, this unit flattens everything out and allows me to keep all the functionality of the factory head unit. It does have a very slight noise floor when using the factory headunit as the main volume control. It's not really an issue though because it's masked as soon as the music starts playing or if you are driving. I would definitely recommend this unit for anyone who is keeping their factory headunit. Note: a black box is a piece of equipment that is set once, installed out of the way and has no user controls unless you use the optional DRC.
Pros: Does exactly what it says it does
Cons: Very slight hiss between tracks when the car is stopped and engine is off.

The TUN is user friendly as long as you have at least basic knowledge of car audio. I used the Advance which is perfect for what I wanted. Because of the unit I was able to run my front components as active and remove the crossover. The highs sound more crisp; whether it is directly related to the TWK or the ability to run active doesn't matter. So far I love it and have a lot more hours of listening and adjusting for ultimate liking to my taste. It will be a lot of time but I am excited about it. Last note: with the use of the TWK and combined with the FIX my sub signal is far better and distortion has decreased significantly compared to the stock signal. The OEM volume will still work and I find myself using both the OEM volume with the TWK volume for desired sound depending on music genre I am listening to. So I can personally say if you have a 09-14 F150 with Sony the FIX TWK combo is a definite.
Pros: User friendly
Cons: Non yet

Bought this unit to create a flat frequency response signal for an aftermarket subwoofer on my 2014 ctsv Bose factory system. The Bose amplified speaker signals have so much unnatural EQ that I was left with finding a DSP that could sum multiple channels to create a subwoofer signal that at a minimum would span from ~20Hz to ~100Hz and time correct between the various channels. Initial use of the Fix did not work well, the output signal after it's initial calibration was quite poor as there were peaks and valleys in the output response of over 10dB. JL was very responsive when I reached out for their help, I would give their tech support 5 stars. Had to obtain a usb to usba cable to connect my PC to the Fix box (don't buy the expensive JL product, just buy a cable), then had to download and update the firmware for the Fix box, and then had to download and use JL's PC interface TUN2.0 software to do the calibration, once all that was done the unit now works as advertised. In addition to installing the box and feeding it enough channels to give it full range audio signals, plan on spending a few hours doing the above to get desired results. The results were a flat sub signal from 25Hz and up, plus there is an EQ in the software that allows a bit of adjustment. And remember to go into the TUN software preferences to ensure the time correction features are turned on, the software is simple but there are some pages that requires some exploring to find
Pros: It works as advertised
Cons: Requires firmware update and you will need to use the PC tuning software

Works great for integrating custom audio with a 2015 Chrysler UConnect stereo. Easy install using using the signal from the front tweeter and midrange speakers to create a flat, full-range 2 channel signal to send to the aftermarket stereo. A JL load sensing adpater was used to keep the factory radio from muting once speakers were disconnected from the stock amp. I added the DRC-100 knob for the optional bluetooth mode that removes the lower frequencies from hands-free calls for better audio quality. Works as advertised and now that a TWK D8 has been added the aftermarket stereo works great and has a lot of tuning capabilities.
Pros: Easy Install and setup procedure, works as advertised.
Cons: None yet

Excellent item! Easy setup, installation, and works great to correct the horrid factory settings.
Pros: Easy to install, setup, and works perfect
Cons: Would say price, but it's definitely worth the cost for retaining your factory head unit, but getting great sound!

Do not waste your time with this. If you are a true audio fan this will surely disappoint you,as it did with me. Weak bass , I am running an alpine 5 channel amp with a type R ten, Weak Weak!

Owning a 2016 ram 3500 I had to take the 8 lines from the stock amp to make it into a single 1 channel analog or digital toslink connection which makes all output flat meaning there is no ability control highs lows front rear sub it's one channel for everything (toslink) those who say it works as is needs to realize it's not working 100% and for those that are frustrated I think they know why? JL will be releasing the TWK in a month or buy a helix dsp 6/8/10 now you will be able to control everything properly Connecting fix 82 to factory amp under the dash then the connect to the DSP for full range not flat then connect output to your 1/500 and 6/150 you would then need a helix 8 extra cost of $600 a lot of time needed but this solution will work for any car/truck I can think of simply cause I have a ram they have everything integrated now into the 8.4u decks it's cheaper then the alpine integration deck of about 15-20 hours labour and cost of about 4K for the actual unit
Pros: Easy install cheap fix compared other methods is small and fit almost anywhere under the dash
Cons: Extra cost of a DSP helix as an example was used 6/8/10 channel whichever you go it will work with this method for all stereo types with the intergration stereo and pre adjusted factory amplifiers

I absolutely love the sound! Crisp signal going to my Alpine 4 Channel Amp. I installed this along side a 4 Ch Amp, Apline Type S Components and 6x9s. All using the factory head unit. When calibrating, I set my volume at 54 when turned up my amp 1/4.
Pros: Small, Easy to Calibrate. It takes the guess work out of getting a flat signal. There are other signal processors that give you much more control. However, if you are trying to flatten out the signal ensuring clipping doesn't occur.. It can be difficult. The only way to properly do it is with an oscilloscope. This simply takes out the guess work!
Cons: I wish it had gain control.

Purchased this to integrate a JL XD700.5 amp into my 2015 Jeep Renegade. Hooked everything up properly, but could not get unit to calibrate. Unit passes signal through to amp with no problem, but won't calibrate via the FIX82 file provided by JL's website. Jeep Renegade does not have a CD Player. Tried many, many options in the troubleshooting guide. Unfortunately, Crutchfield support was not much help either. Hate to return it, as it seemed the best option for me.

2 good to be true always is. This this is far from what JL promised. Stick with Audio Control. Levels are off. Bass output to sub is anemic. It's just bad. Save your money. I am requesting a return. I installed it then thought I should let the pros do it and guess what. Same result. Not sure what these guys were thinking with this thing. Stick to what you know JL. Wasted my time, money with this thing. 200.00 for the installer to try to get it to work gone. I should have just gone with the lci8. Works great in my 14 ram. This thing is garbage.
Cons: Sound quality, poor bass response, signal not flat, poor dsp, price and false advertising

Since this is a new product I had a difficult time finding the Fix-82 locally. Crutchfield had it and it completed my custom JL install. System works loud and perfect.

Since there are no reviews on this unit yet, I thought I would put in my two cents. I ordered this direct from JL as Crutchfield was out of stock on it. I read really good reviews on the cleansweep and thought I would take a chance on this unit. I installed it in a 2015 Toyota Tundra crewmax. After modifying 2 harness to bypass the factory amplifier, I got all of my leads in order for the front and the rear and screwed them into the phoenix connectors for the front and rear channels. Once I had my HD900/5 installed, I fired up the head unit, flattened out my bass, mid and treble and ran the calibration disc. In less than 20 seconds, it processed the factory sound into a usable signal for my new amplifier. I had some positive and negative leads crossed on my rear channels at first so I heard a "hiss" coming from my speakers. After I corrected the problem on the harness the problem went away and I was blown away by the sound quality. No noise or hiss, just a clean signal. I highly recommend this unit if you're trying to keep your factory stereo in place.
Pros: Sound quality, Easy setup, small footprint, gives you a 12volt remote signal out
Cons: If I can nitpick, the phoenix connector going into the unit could grip the signal leads a little better. Also you have to remote the phoenix connector from the unit to screw in the terminals as the flat head screw holding the signal cable in is on the bottom.

More details on the JL Audio FiX™ 82
Overview: The JL Audio Fix82 is a digital signal processor designed to give world-class sound from a factory audio system without replacing the OEM radio. Its 24-bit DSP processor can combine 2-, 3-, and 4-way factory outputs, while automatically level matching into a flat, full-range stereo signal to be passed on to an aftermarket amplifier. The Fix82 will automatically correct factory time delayed outputs before summing the signals and equalizing them with dual, 30 band, 1/3 octave equalizers. Its differential-balanced inputs accept virtually any OEM analog audio signal, from low-voltage line-level to high-power, speaker-level outputs (up to 30V RMS).
Calibration: Basic calibration of the Fix82 is done using the Calibration button on the top panel of the processor. If the button is pressed for 5 seconds, the unit will start the calibration process which takes approximately 30 seconds. The button also serves as an EQ Bypass if pressed for 1 second. By connecting the processor to a PC (via USB) and running the included TuN 2.0 software, you can also access a complete suite of diagnostic panels that will show the frequency response of the input signals, as well as the corrected outputs. This also allows you to adjust the input polarity, muting, and filtering as well as initiating a new calibration. The output can be user-adjusted with a pair of 10-band graphic equalizers.
Turn-On Mode: The Fix82 offers three ways of activation via the top panel Turn-On Mode switch: Signal, DC Offset, and Remote.
- Remote: When the Switched +12 VDC terminal gets 12 volts, the processor powers on.
- DC Offset: Automatically turns on/off by detecting a small DC signal on the OEM speaker outputs.
- Signal: Automatically turns on/off by detecting full-range audio signals on the OEM speaker outputs.
- Input: Factory audio signals are run into the Fix82 through four 4-pin Euroblock connectors for a total of 8 available input channels. Each terminal can accept up to 16 AWG wire. Along with the audio inputs, the processor includes a USB (Type-B, 2.0) port to connect to a PC for running the TuN software.
- Outputs: The processor has two main audio outputs, analog and
- Analog: These consist of a set of stereo RCA jacks outputting a 4 volt (RMS) signal.
- Optical Digital (S/PDIF): The digital port will output a PCM signal at 24 bit/48 kHz resolution. This was intended for use with JL's TwK System Tuning DSP (sold separately) or other processors and amplifiers that have an optical digital input.
- Power/Ground Connector: A 5-pin Euroblock connector provides the inputs for +12 VDC Battery, +12 VDC Switched (remote input if Turn-on Mode switch is set to Remote), Ground, Remote Out (provides a +12 V remote signal to trigger aftermarket amplifiers), and a Valet In. This is provided to attenuate the overall output level by 15 dB if the Fix82 sees a ground on this terminal. This keeps other people from possibly damaging the speakers by turning the volume up too high while the vehicle is being serviced or valet parked.
- JLID Port: The Fix82 has an RJ-45 port for use with JL Audio's optional DRC-100 Remote Controller (sold separately).
DRC-100 Remote Controller: This under-dash mounted rotary control can be used for Master Volume Control or Handsfree Optimization and includes a status LED.
- Master Volume Control: When used as a Master Volume Control, the OEM headunit's volume gets left at the same level it was at during calibration, and the DRC-100 becomes the main volume control. This maintains a linear frequency response and best signal-to-noise ratio at all volume levels.
- Handsfree Optimization: In this mode, the DRC-100 is used to optimize the clarity of the factory Bluetooth hands-free system. By pressing the rotary knob, this disables the processor's time correction and applies a 100 Hz high-pass filter to the output, making Bluetooth phone calls clearer to understand.
- Status LED: The DRC-100's multi-colored LED will show the Fix82's
- Constant green: Normal operation
- Slow flashing green: Valet mode is active.
- Constant amber: Handsfree mode is activated.
- Flashing or constant red: Input signal is clipping (lower volume control on OEM headunit).
Status LEDs: Four LEDs on the Fix82's top panel display both the Input Status and the Calibration Status with two LEDs for each (Left/Right channels).
- Input Status:
- Green: Signal present.
- Amber: Power on, no signal.
- Momentary Red: Input signal is clipping.
- Calibration Status:
