The DSP4086 gives you serious tuning power, including time alignment, variable crossover slopes, phase adjustments and signal summing. It's a jack-of-all-trades that you can configure the way that makes the best sense for your particular vehicle.
Each channel offers 40 watts of amplification at 4 ohms, or 60 watts RMS at 2 ohms. The DSP4086, despite packing a lot of processing power, is very compact so you'll have more options for placement. Fine tuning is possible when you connect the amp to a Windows computer, letting you tweak the sound to your heart's content.

i put one of these in my 2021 Ridgeline. what a difference it made even with the factory speakers
I come from the era of Phoenix Gold M and MS, Punch, and old JBL GTi speakers. The things that tech can do now days is just amazing. The amount of power they can make for the amp draw is insane. We spoke of 48 volt car systems back then, if it ever comes to fruition it's going to get even crazier.
Amazing for sure! What are some of your favorite current models?
Can you run only 2 sets of RCA inputs into this and assign them to still get 8 channels of output? Thus connecting the third preout set from a HU directly to a more powerful monoblock amp?
Hi James, if your source unit offers 6-channel preamp outputs, you can connect the front outputs to inputs 1 and 2 on the amplifier, and the rear outputs to inputs 3 and 4 and then specify your exact setup via the audio settings you make. Keep in mind, none of these channels are designed to be bridged.
It's a shame you can't bridge channels as that would help massively with a sub woofer, or would it be possible to run 2 channels to a DVC sub? and link the outputs
Channels 7 and 8 can be assigned as subwoofer outputs. It is possible to wire one channel to one voice coil on a DVC subwoofer. We cover this and more on our web page for it and here's a link to that page:

Is there any benefit to using the front 2 channels only for the door woofers, and the rear 2 channels (RCA's) for only the tweeters (2-way components without their external crossovers)? Does summing from the front channels in the mixer to both the woofers and tweeters provide full wattage to both the woofers and tweeters, or is it halved?
Also, how would I use the dsp to control a stronger bass amp that doesn't have speaker level inputs?
The best setup will depend on your exact speakers and preferences. The amp has 6 input channels that can be summed and assigned to any of the processor's 8 powered output channels. The audio signal from any input channel can be assigned to any output channel. Multiple input channels can be summed to the same output channel, allowing a full-range speaker to get its signal from separate tweeter, midrange, and woofer signals in a factory system.
Each channel can have its own 31-band parametric or graphic EQ, high- and low-pass crossovers, with selectable slopes, time delay, and more, all configured using you connected Windows PC.
My boss elite has front L&R Back L&R on the preamp out puts. So do I have to cut the wires from the harness to do all 8?
You would not need to cut any wires from this amp's harness. Any unused RCA inputs can be left in place and any unused outputs can be capped off.
Noticed people (elsewhere) talking about higher failure rates on this unit. May I inquire as to whether or not Crutchfield has noticed numerous faulty unit claims from customers?
I had one arrive DOA.... However I bought a Reconditioned unit from eBay ... Either way Harmon (JBL) and Road entertainment made it right and I've been using the replacement unit well over a year in the toughest environment on the roughest roads in the nation without issue..... It in the saddlebag of my motorcycle with minimal cooling in Louisiana where our potholes are landmarks

Will this work in a 2010 Titan with Rockford Fosgate factory system and how difficult it is to install?
You would have to bypass the rockford system, and replace the speakers in the truck. I'd say it's a 7/10 on overall install, as you will have to run new wires, and replace the speakers. One of our advisors would love to help you get it all sorted! bit.ly/2KP1zS3
I have a y62 patrol, I think it's an Infinity qx80 over in the states.
It has a Bose "premium" system with sub ect.
I have no idea how many watts RMS that has, but it literally has a bass and treble slider, no eq, nothing.
I'm keen on this unit to splice into it, but not sure the RMS power of this amp is going to be sufficient for decent volume?
We do not have the watts RMS rating for the stock speakers in the Infinity QX80 SUV's. We recommend replacing the speakers with some aftermarket models that can work with the JBL's power
@crutchfield What would be the top 2 DSP+AMP options for Focal ES165 K2 (Front) + Focal 165AS (Rear)? Been recommended the Helix M Four DSP but looking for more affordable alternatives w/o sacrificing SQ. Thanks Crutchfield Fam! :)
We're glad to help. What is your preferred budget for the amp?
I can’t figure out how to save my equalizer setting to the amp fully it sounds good after I edit it on the computer once I turn my car off the amp goes back to a default setting it makes it sound flat again with 24db slope on all speakers I can’t figure out why it’s doing that
The manual does not give any troubleshooting steps to help resolve your issue. Did you connect its power wire to the battery? If you didn't, then that could be causing the issue. If you did, then you will want to speak with a technician to troubleshoot the issue. If you purchased it from us, you can contact our technical support. We include their toll free phone number on the order invoice
My wife wants to keep the factory head-unit on her 2015 Buick Enclave with a factory BOSE system... Can this unit overcome the funny things that BOSE does to the audio signal without needing to buy anymore equipment to flatten the signal prior to processing? Thanks
Adding the new DSP and EQ is a great way to clean up the sound. Your best bet is to add new speakers and wiring as well.
Hi, I have a 2017 Toyota Tacoma with the jbl set up . I recently swapped the speakers and put JBLGTO. I have that stock amp and sub woofer that it comes with,was wondering if this amp would work??
For better help matching the amp with your speakers and integrating into your OEM system, I would reach out to an advisor! bit.ly/2KP1zS3
Yes it works. Take the front, rear and sub channels from the factory amp into the input of the 4086, use the software and it will work.
Hi
I have Bwm328i 3012, that have 7 speakers including 2 underseat subwoofer
Will this amp work for me ?
This amp could be used to power aftermarket speakers installed into the stock locations in your vehicle. At the time of this post, we do not have a subwoofer that will fit into the factory location and would need to install that elsewhere. If that is ok, we recommend contacting an advisor to get help building a replacement speaker system for your BMW. Here's how to reach us for this help:

I have the JBL 4086. I am getting speaker pop after the car is shut off from an amp that I have hooked to the remote out. I put the power on delay to 20 seconds but I'm still getting speaker pop?
We cannot find any troubleshooting steps in the manual for resolving a popping sound and recommend contacting technical support for help. If it was purchased from us, you can contact our technical support for help. We include their toll free phone number on the order invoice
I know this comment is a year old, but just installed this on my Tundra and getting pop when turning both on and off. Were you able to fix it?
Can i use this with my current speaker sir
Proton Preve Stock Head Unit
Front Speaker
JBL Stage3 607CF
50Wrms, 250W peak
Rear Speaker
JBL Stage3 627F
45Wrms, 225W peak
This DSP amp can work with those speakers and still have extra channels should you decide to add more
Can I use a Stadium 4 with the DSP4086 to increase power? Thank you.
Yes they can be used together! The 40 watts RMS output of the amp does not exceed the maximum input level of the Stadium 4 amp!
@@crutchfield Thank you very much, this is very helpful!
Anytime!
I just bought this I hope it really sounds better than the factory amp. I have aftermarket speakers
Great choice! What is your exact setup?
@@crutchfield kicker CSC65 all around. Looking to rout 2 tweeters 4 6.5 and 2 3.5 .
A vehicle with that many speaker locations is likely to have a DSP in the factory amp and that type of factory amp can often have different impedances it is expecting with the speakers. This JBL just might do the trick!!
@@crutchfield they guy I bought it from didn’t ship. I was thinking of going a different route. Can I connect some speakers to crossovers then over to a Lc7 i then to the amplifier ?
You could connect the stock amp to the LC7i, then to this amp and then to new crossover and speakers
how much louder is this that say a factory radio. in my case F150 non sony 2017 truck with 8" screen. When i see 40 watts i think that isnt alot compared to what i am used to seeing on other amps. not planning on using for subs only running active fronts
You're right, 40 watts doesn't seem like much but it really is more than it sounds. A stock non-amplified audio system in most cars only produce about 3-5 watts per speaker. Amplified systems like Bose, Harman Kardon, etc don't produce much power either. So realistically 40 watts rms x8 is going to give you a lot more volume than a 5-25 watt stock system. The sound quality will also be much more clear and crisp. More power driving speakers will allow them to perform better and you'll be able to hear detail you were missing before. Since this amp has a digital signal processor built in you're going to get even better sound since you can really fine tune your system with the 31 band eq.
I am having problems with the program to set up the amp
Who can help me ?
If you got the amp here, please call our Tech Support. Their direct number is on your invoice.
I bought it on ebay
Do I have the support ?
You can reach JBL's Customer Support at 800-336-4525.
Man if they added 1 pair of RCA outputs for subwoofer amps. Maybe the next generation would include this and stagger the power so the mid-bass drivers get 100watts.
Not needed, high level connections are fine most amps support it.
@@dj4monie more chance for noise to enter. I have to have a low noise floor.
@@ericperry72 not really..... High level inputs are higher voltage and typically a cleaner signal.... But you could still use one of the supplied RCA adapters as a low level input and dial the output voltage back in the software..... It has a 60 point adjustment range
How to order?
Hi Christian, we do have the JBL DSP4086 available for order here: www.crutchfield.com/I-rYALc921/p_109DSP4086/item.html
Why don’t they just send it with a microphone like the kicker key. I would have absolutely NO idea how to tune the timing and everything just sitting in the car with a computer pressing buttons.
We believe this unit is geared more towards the users that like to tweak the settings because there is no autocalibration mode in it. Maybe that will come in a second generation model!
Do the timing with a tape measure. Set the crossovers based on which speakers you have. If you want to tune further, you are in for a certain amount of commitment anyway, just buy a mic at that point.
Shut up and take my money
My boss elite has front L&R Back L&R on the preamp out puts. So do I have to cut the wires from the harness to do all 8?
You would not need to cut wires but would need to use the DSP in the amp to distribute the audio from the 4 RCA inputs being used by your radio to the any of the 8 channel outputs. The unused output can be capped off so they don't touch anything.
