Product Description

When you see a moderately priced amplifier loaded with chrome and lights, you know that the money to pay for the bling came from somewhere, and that 'somewhere' is under the hood. By contrast, when you inspect a JL Audio JX amplifier, you will see that nothing is spent on gimmicks, blue lights or chrome. Instead, we apply our no-nonsense, pure performance philosophy to specify oversized output transistors and rugged MOSFET power supplies that ensure ample current and thermal capacity. These beefy parts operate well under their limits to deliver stable performance and vastly better reliability than the wimpy devices commonly found in many competing products. It all adds up to solid bass definition and cleaner, louder high frequency output that gets the most out of your speaker system. To get your system dialed in just right, we also include flexible signal processing capabilities with fully variable crossover filters, pass-through preamp outputs and a Bass EQ. The monoblock models also include a port for an optional Remote Level Control. Active Crossover Features Fully variable 12dB/octave filters controls offer excellent tuning flexibility. Remote Bass Level Monoblock models also feature the ability to control the bass level from the front seat with an optional RBC-1 Controller (sold separately). Hi-Level & Low-Level Inputs JX amplifiers have both Hi-Level (speaker level) and Low-Level (pre-amp level) inputs for maximum installation flexibility. Class D Amplifier Circuit The JX1000/1D employs an advanced Class D switching design that allows it to produce 1 kilowatt 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. Preamp Outputs Pass-through pre-amp outputs permit interconnection of multiple amplifiers. High-Mass Heatsink. Rugged MOSFET Switching Power Supplies.

No need for earth shattering bass for me though.

Its a great amplifier, JL always makes great stuff, unlike other manufacturers - JL is honest with their customers.

I bought this amp to power my 12" JL W3 V2. It took me a while to get it tuned in, but the sub sounds amazing. If you buy this and find that you aren't getting any output from you sub, but everything else checks out, try turning the input sensitivity up just a bit. I had this problem with mine; also if you purchase the remote level control, make sure to tune your amp with this UNPLUGGED. I had to call JL tech support a few times before I figured out what the problem was, but they were very helpful. I highly recommend this amp!

Quality Amp. This is another great piece of equipment from JL. The amp is powerful and clean. We used it to power the JL CP108LG-W3v3.

This amp may only be a 250W but it sounds perfect. I paired this with a JL 10" low profile. AMP has protection mode (awesome), is great for single sub application, and looks great. No complaints.

I have this paired up with a JL 10W3V3-4 and I love it. I'm not trying to break windows or ear drums with this setup, but I can if I choose to.

This amp provides excellent power flow for any quality subwoofer, though I wouldn't hook this up to something rated above 600 watts simply because you wont be able to push the sub to it's potential with that, but if you're running something similar to what I am, this am will run all day.

Pros:
JL, everyone loves JL, they're the best for a reason
compact, has a very small foot print and can easily be stealthed away or mounted to a seat with little difficulty.
easily adjusted filters and well laid out connections
4 GA power/ground, not that you need that much juice to run this, but it doesn't hurt to have the capacity.

Cons:
It's not Class D.

I don't know much about amps but I know this one overheats. Maybe one day when I have time, I will raise it off the floor a little to let heat escape more freely, but this amp will last only about an hour if it is mounted closely to the floor. I didn't do the install myself, so when I have time I will fix this problem, but other than that, my speakers get really loud with this bad boy.

Paired this with the JL CS112-WXV2 and the remote bass control and fill an FJ Cruiser with nice bass. Had the amp turned way down and still found myself turning the remote bass control down. Highly recommend!

paired this with the JL RBC-1 and JL 12" WxV2. Considering it's all JL parts, they all work PERFECT together.
