About the JL Audio VX1000/5i

Amplifier plus DSP

We heard a lot of pre-launch buzzing about JL Audio's VXi Series amplifiers, which combine JL Audio's latest amplifier technology with powerful signal processing. JL Audio teamed up with micro-device maker AKM™ to create this customized processor-amp hybrid. They also improved the amp's Class D performance by shortening the signal path through the amp, placing the output capacitor banks nearer the outputs, and using up-to-date DirectFET® MOSFET output devices, resulting in higher efficiency, reliability, and audio quality.

Power and tune your whole system

The VX1000/5i 5-channel amplifier puts out 4 channels of 75 watts RMS, plus up to 600 watts RMS for a sub. It also features 7 channels of digital signal processing, giving you lots of flexibility in setting up a system. For instance, you can power a system with 2-way component speakers (tweeter and midrange woofer) up front and a sub in the rear, while providing a processed signal for a separate amplifier for  rear speakers. You could also use this amplifier in bridged, 3-channel mode to power a couple high-performance speakers with 200 watts RMS each and a sub with 600 watts.

Digital accuracy

The 24-bit 96 kHz processing for each channel includes signal routing and mixing, 10-band parametric EQ, time-alignment, high- and low-pass filters, and output level control with 0.1 dB precision. In addition to tuning the audio signal, the processor provides a master clock signal for the Class D amplification, increasing audio accuracy.

Remote control only

You make all your settings and adjustments from your compatible device running JL Audio's TüN™ software.

  • PC and Mac OS: TüN 3.0 — requires a USB connection (6' cable included with amp)
  • Android and iOS tablets: TüN Mobile — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately)
  • Android phones and Apple iPhones: TüN Express (for Basic setups only) — requires Bluetooth connection and the VXi-BTC Bluetooth communicator (sold separately)

Other accessories you may want with this amp

This VXi amplifier features JLid™ inter-device connection ports for JL Audio's proprietary network system for controlling data. The DRC-205 digital remote control lets you adjust the master volume, subwoofer level, switch between up to six preset tunings, and indicates the amp's status via LED. An optional VXi-HUB network hub comes in handy when you have three or more VXi amps in your system, coordinating all the adjustments and controls. A FiX 82 or a FiX 86 can be used to remove factory sound processing, for higher-fidelity factory system integration for your VXi amplifier.

JL Audio VX1000/5i

Crutchfield customer from Cleveland,OH on 8/10/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

Fantastic sound quality Can power standard 4 channel & sub or active 2channel & sub with infinite xover points & slopes for all. TuN app required to setup properly Bluetooth dongle allows use of phone or tablet Laptops are usually wired & allow most advanced settings & disconnected after settings complete. TuN can store multiple system setup profiles available at your fingertips with Bluetooth. You can have your profile for late-night driving, audiophile sound, or kick ass Boom. With the built-in equalizers crossover points & slopes, Made my factory car speakers sound like a $600 pr speakers. (W6 helps) I know sound! My home speakers were $12,000pr when I first released. Five Stars Aren't Enough

Pros: With Control of all of the different parameters of your car speakers sound, you can make your existing car system sound better. I have ordered car speakers but the VX1000/5i is making me reconsider whether I really need them or not !

Cons: Be Prepared to spend some time learning how to use the TuN app there is a tutorial onLine that is very explanatory and easy to follow. With patience you will be rewarded with great sound sound

One of the best amps for the money

Douglas from Baltimore, MD on 1/4/2019

Verified customer (What's this?)
Verified employee purchase (What's this?)

I had this amp in my truck since it was released. I have it powering my focal k2 in the front and focal flaxs in the rear with my Jl stealthbox. I came from the jl hd900/5 which sounded awesome. The sound is so much better coming from this amp. The infinite adjustments you can make with this amp makes it an audiophile dream. Also with the bluetooth dongle you can make adjustment with your iPad and or smartphone. I prefer using the iPad because you have more control over the functions of the amp. Also the knob is another great feature if this amp.

Pros: The infinite adjustment Built in DSP Toslink input

Cons: None

Super configurable, clean looking, clean sounding, Toslink!

Keith from Powell, OH on 11/13/2018

Verified employee purchase (What's this?)

What a fantastic piece.I am running Focals in my doors and a JL13T5 in the back. This thing handles all of it with no problem. I love that it has Toslink in/out as well which really cleans up the install. The Tun software is super simple to use and is endlessly configurable. No real complaints about it other than I wish it had built in blue tooth so I can use the mobile Tun software. I have to buy another piece to activate that.

Pros: Great sound/look/power/support.

Cons: none

Great amp not an easy setup but worth the cost

Michael from Bremerton, WA on 6/6/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

So let me start by saying the amp itself in fantastic. I have and replaced a HD900 JL Audio for this. My issue is I asked several questions regarding this from tech support. My question were I have the fix 86 and the HD900 in my 2016 F150 Limited with the not so great Sony system. My fix is a year old and the TUN software was not included and the adjustments that can me made with your laptop are great like on this new version. The issues was you could power the door speakers using a splitter into rca as this amp has no direct way to wire in speakers. So I purchased three of those and only the doors worked apparently to power the sub you needed a converter or sound processor like I already had and wanted to eliminate with this amp. So I tried a LC7I Audio control still not what it was capable of. So in the end I reinstalled Fix 86 and it is truly amazing with all of the adjustments tuning etc and the bass out of my JL Audio stealthbox is way cleaner and much more bass the HD900 not sure why but it is. So long drawn out review is for my application I was unable to just have the VX1000/5I run my system as I was told I could. The TUN software unfortunately the tech support guys just haven't had their hands on it enough but were a great help trying to figure it out with me. Not for the timid but it will amaze you every time you turn it on. I have Focal 6 1/2 ES165 KX2 up front and EC165K in the rear and the JL Audio Stealthbox they say doesn't fit but JL sites does.

Pros: tons of adjustments and small footprint and expandability and great power

Cons: No support from Jl Audio on their own software required to make the amp even work and the cost but when you want the best it will cost you

Amazing product

Crutchfield customer from Wheat Ridge, CO on 4/15/2018

Verified customer (What's this?)
Verified employee purchase (What's this?)

This thing is pretty great. It's not a do it yourself install though. It has to plugged into a computer with the right program before it will turn on for the first time. The dsp is pretty good but have it programmed by a professional. It will save settings so if you want a few different sound stage settings you can get a three function bass knob to control the settings. It's powerful and super clean. Of course I'm running Focals and a 10" JL W3. I was the first to bring this in to car toys and they kept the car for two and half days to figure out all the features. It's super small and will literally fit anywhere. Great product JL. Spendy bit worth it. Crutchfield is also the easiest company to to buy from and very tech supportive.

Pros: Awesome versatility and function

Cons: Pricey but you get what you pay for

Connections

Power/Ground/Turn-On Terminals: The VX1000/5i features a removable plug with C-Clamp terminals for the power, ground, and remote turn-on cables. This allows you to pre-connect the wires to the connector, then plug it into the amplifier. The power connector will accept up to 4-gauge power and ground wire, and 10-18-gauge wire for the remote turn-on. The supplied 3mm and 2.5mm hex wrenches are for tightening/loosening the C-Clamps.

Note: The amplifier is not equipped with a fuse. An external 80-amp AFS, AGU, or MAXI fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 80-amps, the original should be replaced with an 80-amp fuse.

Speaker Output Harness: The JL Audio VX1000/5i features a removable ABCD Speaker Output Harness with 18" wires, plus a removable Subwoofer Output connector with set-screw terminals. The connector's two set-screw terminals will accept 14-gauge to 10-gauge speaker wire. A 2.5mm hex-wrench is supplied for tightening/loosening the set-screws. The included 18" length of flexible loom is to cover the subwoofer speaker wire at its connection with the amp. The loom matches the look of the Speaker Output Harness, and makes for a clean, uniform look.

Analog Input Harness: The amplifier has a 25-pin D-Sub connection for the supplied 14" Analog Input harness. Four loom-covered cables exit the cable's D-Sub connector, with three pairs of stereo female RCA inputs, stereo female RCA preamp outputs (4V max output), the remote turn-on output (+12V) and Valet Preset Toggle lead.

Digital Inputs/Outputs: The amp has optical digital (Toslink) inputs for direct connection of S/PDIF digital sources, bypassing the A/D converter. The input accepts up to 24-bit/192kHz signals. There is also a Toslink optical digital output for sending a digital signal (24-bit/96kHz) to another VXi amplifier.

USB: A Type B USB port is provided for connecting the amp to your computer for interfacing with the TüN software. A 6' Type A to USB-B cable is provided.

RJ-45: Two RJ-45 modular ports are provided on the amplifier for optional accessories:

A
We don't have a way to track if any of our customers have tried using on various vehicles. I know that a vehicle without an amp would work with it as stock radio's will not output more power than this amp can take in. My Bio: https://www.crutchfield.com/bio/Paul
