Features

Monoblock Amplifier: The JL Audio JX1000/1D monoblock subwoofer amplifier that has been optimized for low-frequency (20-150 Hz) amplification of connected subwoofers.

Note: The JX1000/1D is not designed for driving full-range speakers, midrange drivers, or tweeters.

Class D Amplifier Circuit: The JX1000/1D employs an advanced Class D switching design that allows it to produce 1,000 watts of clean subwoofer power while drawing significantly less current from your electrical system and generating less heat than a conventional Class A/B or Class B design.

MOSFET Switching Power Supply: The JL Audio JX series monoblock amplifier employs a rugged MOSFET power supply for outstanding reliability and operational stability.

Amplifier Ratings:

JX1000/1D Amplifier Specifications Ohms Watts Channels Frequency Response Signal-to-Noise THD

3 750 1 20-200 Hz 75 dB 1%
2 1,000 1 20-200 Hz 75 dB 1%
Rated Continuous (RMS) Power @ 12.5V 4 500 1 20-200 Hz 75 dB 1%
3 700 1 20-200 Hz 75 dB 1%
2 900 1 20-200 Hz 75 dB 1%

High-Mass Heat Sink: A heavy extruded aluminum heat sink is designed to keep the JL Audio JX series amplifier in a comfortable thermal range during demanding operation. This high-mass, extruded heat sink removes heat from the amplifier circuitry, extending high-power operation. This improves reliability and reduces the frequency of thermally related shut-down event.

Protection Circuitry: The JX1000/1D's protection circuitry automatically shuts the amplifier down if thermal limits are exceeded, a short-circuit is detected in the speaker wiring, or if low supply voltage limits are reached.

Status Indicator Lights: There are two status indicator lights on the right side of the amplifier.

  • Power (Green): This LED lights green to indicate that the amplifier is turned on and operating normally.
  • Protect (Red): The Protection LED lights Red to indicate the amplifier's protection circuitry has been activated to prevent product failure due to thermal overload, a short-circuit, or a dangerously low impedance connected to the amplifier's outputs.

Controls

Input Sensitivity: The Input Sensitivity Control is used to match your source unit's output voltage to the input stage of the amplifier for maximum clean output.

  • Low-Level Input Range: 200mV-4V (RMS)
  • High-Level Input Range: 2V-10V (RMS)

Low Pass Crossover: The JL Audio JX1000/1D monoblock amplifier is equipped with a 12dB/octave Butterworth low-pass filter with variable frequency selection from 50 to 200Hz.

Bass Boost: The amplifier is equipped with a variable 0 to +12dB, 45Hz Bass Boost.

Remote Level Control: The JX1000/1D is equipped with an RJ-25 connection for an optional wired Remote Level Control (136RBC1, sold separately) that allows volume level adjustment of the amplifier from the front of your vehicle.

Connections

Power/Ground/Turn-On Terminals: The monoblock amplifier features set-screw terminals for the power, ground, and remote turn-on connections.

  • Power and Ground: The JL Audio amplifier's set-screw Power and Ground connections are designed to accept 8 to 4 AWG power wire. A 2.5mm hex-wrench is supplied for making connections.
  • Remote Turn-On: The JL Audio JX series amplifier's set-screw turn-on lead will accept 18 to 8 AWG wire. The same 2.5mm hex-wrench is supplied for making connection.

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 a 80-amp fuse

Speaker Output Terminals: The JL Audio JX1000/1D features four set-screw speaker terminals for an easy parallel subwoofer connection. The monoblock amplifier's four set-screw speaker terminals will accept 16 to 8 AWG speaker wire. A 2.5mm hex-wrench is supplied for making connections.

Preamp Inputs: The monoblock amplifier features one set of stereo RCA input jacks. The amplifier features a dedicated Input Sensitivity gain control for these inputs. These controls are designed to match the input sensitivity of the JX1000/1D to the specific signal source that is feeding it. The amplifier's low-level input can be set between 200mV-4V RMS.

Speaker Level Inputs: The JL Audio JX1000/1D also accepts speaker level signals, including those from factory systems (without the need for a line-output converter), via the supplied 10" speaker-level harness. The amplifier's high-level input can be set between 2V-10V RMS.

Preamp Outputs: The JX1000/1D incorporates a pass-through preamp output sections, so that additional amplifiers can easily be connected to the same signal(s) feeding the monoblock amplifier. These preamp output signals are buffered to prevent noise and are always preamp level, regardless of the level of signals feeding the amplifier's inputs.

because of the12W7AE i bought from you guys [ CHRIS  Jul 04, 2016 ]
A
I've owned several different brands of high quality mobile audio amps, and JL Audio is superior to all of them in many ways. I have been using JL for over 15 years, and I will probably never change. [ David  Feb 01, 2016 ]
A
I love JL's subwoofers, they're my absolute favorite. The sound quality can't be beat. I don't like my car to rattle, I like that nice clear sounding bass. JL stays on point. So I bought this amp to pair them up, I can't wait to hear how they sound. This amps give me a few options to run 1000w or 500w. I'll start off with 500w. The sound quality can't be beat.

Q
Can you run two 12s and a 15 inch subwoofer with this amp?
[ Presentacion  Mar 01, 2019 ]
2 answers
A
IMHO yes, BUT, only if you really really know what your doing wiring wise. You will have to do a series/ parallel combo and make sure your math is accurate for the ohms & Watts combo or you will fry your amp and subs
[ Scott  Mar 02, 2019 ]
A
Yes. This amp is a monster and will push just about anything you throw at it. You need to figure out the final impedance of the total speakers you use to not drop the amp below 2 ohms and you'll be ok
[ Robert  Mar 02, 2019 ]
Q
Would this amp work the best with a W7-10? Also can I connect this amp to my existing JL 4 channel for power?

JL Audio 12W3v3-4 Would be best that's what I have and it's also I would recommend it to anyone
[ MATTHEW  Sep 20, 2017 ]
Q
If I use both outputs for two subs. one output to the first sub and the second output to the second sub (both at 2 ohm) do both subs get a rms of 1000w or does the power get split because I'm using both outputs and each speaker only get 500 ?
[ krimsen  Jun 22, 2017 ]
1 answer
A
No. The amplifier is only one channel (mono). The two sets of output terminals are provided for convenience when connecting multiple subs. The amp is not 1 Ohm stable so, you cannot wire two 2 Ohm subs in parallel. You can wire two 4 Ohms in parallel and present the 2 Ohm final load when you do. This will get the full 1000 watts RMS from the amp with each sub getting up to 500.

Q
Will the amp be enough power for 2 15s cvx?
[ David  Apr 06, 2016 ]
1 answer
A
I can't actually answer the question, because I am using my JX1000/1 to power my one Alpine SWR12D2. I don't know what vehicle you have, but I can tell you this. I can make everything shake cleanly in my 2008 Toyota Corolla. Like all JL Audio products, it is an excellent amplifier!
[ David  Apr 07, 2016 ]
Q
using 2 Rockford Fosgate p3 subs with this amp is it best to wire it to 1 0me load or tow ome loads?
[ Timmy  Dec 30, 2015 ]
1 answer
A
This amplifier is not 1 Ohm stable so you'll need to be able to wire the subs for at least 2 Ohms. I hope that helps!
[ Ryan  Jan 01, 2016 ]  Staff
Q
with the variable low-pass filter can the amp be tapped into the rear speakers of a car? or does it need the line in converter still?
[ andrew  Jul 05, 2015 ]
1 answer
A
I forwarded your question to an Advisor and they responded with the following: The JL Audio JX1000-1 has speaker level inputs so you can tap into the rear speaker wires. You don't need a line output converter. If you would like to discuss further you can contact an Advisor directly by phone (1-800-324-9695) or online chat.

Q
I just bought an alpine typer swr12d2. I have the jdx1000-d amp. It says I can only wire the sub at 4 or 1 ohms.I am currently running at 4 ohms like it suggested but i'm not impressed and think it can be a lot louder. Should I return this amp and get one that is compatible with my single dual voice coil type r or is the amp capable of running at 1 ohm ?
[ K  Mar 10, 2015 ]

My set up consists of two JL Audio 10W3V3-4's & the JL Audio JX1000/1D. The subs are 4ohm but I'm going to wire them in parallel so they each can get the 500 watts the amp can deliver. With one sub there are limited options so my recommendation would be to go with two subs. It is a bit much for my main genre of music which is jazz but I do like old school hip hop & R&B along with some new school music. Point is when I want clean, hard hitting bass I have it. Take into consideration how much you are willing & can afford to spend & your style of music & hit up the advisors. That helped me a great deal & helped me understand the components & what is suitable for my flavor of music. Oh, almost forgot...space! How much of your vehicles trunk or hatch back or SUV space are you willing to devote to your sub box because it is going to take up space. My box build will be complete next week so I'll let you know how my system turns out. Til then, happy listening!
[ Tarick  Mar 14, 2015 ]

What's up K! I have not put my system together yet because I am building my own box so I can't offer up any credible feedback on performance just yet but when I was shopping for all my components, I asked a lot of questions as to the amps capability. I am almost certain it's capable of running as low as two ohms, if you were using two subs like I am. I can research this a little further and get back to you but I think it's safe to say no...it can't go as low 1ohm...but don't quote me just yet.
[ Tarick  Mar 13, 2015 ]

I have the same mono block amp but it set at 2 ohms and its is pushing my JL 10w6v3-d4 sound good also I install the JL clean sweep which is an Oem integration.. To have the clean crisp sourround sound...

Send it back and get a better amp, I bought the same amp and I am not impressed at all
