Our take on the JL Audio Slash v2 Series 1000/1v2

by Buck Pomerantz
JL Audio

My system has plenty of power. Who needs an amp?

You might think you don't need an amp because you have a 400-watt system in your car, or because your new stereo puts out 50 watts a channel. But those are peak wattage ratings, which may boil down to 15 or 20 watts per channel, using the more realistic RMS rating. An amp sends your speakers the power they need to deliver your music with clarity and impact, whether you're using factory speakers or high-performance components. And low-frequency reproduction requires lots of power, so an amp is an absolute must if you're adding a sub to your system.

Consistent power for performance you can count on

Inner works of Slash v2 amp

JL Audio's Slash v2 amplifiers aren't just powerful, they're smart. As your battery voltage fluctuates while you drive, the Regulated, Intelligent Power Supply™ system maintains steady, consistent power at any impedance between 1.5 and 4 ohms and at any voltage between 11 and 14.4 volts. You'll get all the power, all the time, even with a wide range of speaker combinations.


1,000 watts of reliable power

The 1000/1v2 mono amplifier puts out 1,000 watts RMS of clean power to your subwoofer system, and JL Audio's patented Class-D amp circuitry keeps a tight rein on cone movement. The cast aluminum heatsinks dissipate heat quickly, giving these amps long lifespans and reliable operation. You'll find all controls, inputs, and outputs on the front panel, for easy access and a neat installation.


Minimize external noise

Differential inputs for low noise

JL Audio amps use "differential-balanced inputs" to isolate the signal's ground from the chassis ground, reducing noise and making Slash v2 amplifiers compatible with almost any system, including most factory radios.


Fingertip control

Tunable frequency filters and a parametric EQ bass boost give you precise control over your bass sound, and the optional RBC-1 wired remote lets you dial in the right amount of thump from the front seat.

Features

Mono-Channel Subwoofer Amplifier: The JL Audio 1000/1v2 is a class D monoblock subwoofer amplifier that is rated at 1,000 Watts RMS x 1-channel in 1.5 to 4-ohm at 20 to 250Hz with a signal-to-noise-ratio of 95 dB and a total harmonic distortion of 0.05% while receiving 11 to 14.5 Volts. The JL Audio subwoofer amplifier's frequency response is limited to the range of 5-250Hz and is not designed for driving midrange speakers or tweeters. Every aspect of the amplifier's operation has been optimized for low-frequency amplification.

R.I.P.S. (Regulated, Intelligent Power Supply): R.I.P.S. stands for "Regulated, Intelligent Power Supply" and is a central feature of the JL Audio's Slash v2 amplifier. The JL Audio R.I.P.S. System ensures consistent power delivery over a wide range of battery voltages and load impedances. This technology provides optimum power at any impedance level between 1.5 ohm to 4 ohm per channel and at any vehicle voltage level between 11V and 14.5V.

  • Regulated Power Supply: "Regulated" means that the power supply adjusts its operation so as to maintain the amplifier's rated power output and low distortion operation over a wide range of vehicle voltages (11V-14.5 V). This allows the JL Audio Slash v2 amplifier's the rail voltage and clean power output to remain stable in real-world car-audio systems, resulting in superior fidelity and stability.
  • Intelligent Power Supply: The "Intelligent" portion of the R.I.P.S. System is a circuit that actually monitors output current to optimize the amplifier's output power over a wide range of load impedances (1.5 ohm to 4 ohm per channel). The R.I.P.S. System detects the actual impedance being driven and adjusts output rail voltages to deliver optimum output. The entire process is seamless, automatic, and results in incredible dynamics for satellite channels and consistent power output for a wide range of subwoofer configurations. It also takes into account the real impedance of your car-audio system, rather than relying on often inaccurate assumptions based on a speaker's rated impedance.

Monolithic RealSink Plus Advanced Heat Management: This Slash v2 amplifier features a real cast-aluminum heat sink with vertically-oriented fins that are highly effective at dissipating heat from the amplifier via convection and radiation. The design of this heat sink is achieved through extensive finite-element analysis, resulting in an amplifier that keeps cool under the most demanding conditions. If a Slash v2 amplifier should ever reach an unsafe temperature, our unique Advanced Rollback Protection circuit also adjusts power until the amplifier cools down, without ever shutting your music down. As an added cosmetic benefit, the cast-aluminum end-caps of the Slash v2 amplifier replicate one-half of a full heat sink fin so that when two or more amplifiers are mounted end-to-end, you get a totally seamless custom look.

Class D Circuitry: This JL Audio Class D subwoofer amplifier utilizes a proprietary Class D circuit. JL Audio's Patented Class D output circuit utilizes a discrete control section and a unique feedback loop design that results in outstanding power regulation and a damping factor greater than 500 at 4 ohms (>250 at 2 ohms). This is vastly higher than other Class D designs and also higher than most Class A/B amplifiers. The benefit of this exclusive JL Audio technology is tight, clean bass reproduction with the efficiency advantage of Class D amplification.

Differential-Balance Inputs: The JL Audio amplifier features differential-balanced input architecture to effectively control noise and ensure compatibility with a wide variety of source units, including many OEM systems. Without resorting to line output converters, you can directly connect most OEM source units to the JL Audio amplifier without creating any noise or compatibility issues. Unlike conventional single-ended inputs, the differential-balanced design does not connect one side of the audio signal to chassis ground. This eliminates any voltage sensitivity between one input terminal and ground and greatly reduces the incidence of alternator whine in a typical car audio installation. The Slash v2 amplifier provides range switching on each of its inputs via the "Input Voltage" switch. This permits connection to a wide range of source voltages while retaining excellent sensitivity setting precision.

Note: You will need a speaker wire to RCA adaptor (136XDCLR2S, sold separately) to connect this amplifier to your headunit via speaker-level.

Flexible Preamp Outputs: The Slash v2 amplifier features flexible preamp outputs that make interconnecting multiple amplifiers simple. The 500/1v2 subwoofer amplifier features fully-independent preamp output filters with independent frequency (40-200 Hz), mode (LP or HP) and slope-selection controls (12 or 24 dB). The preamp outputs can also be configured to track the amplifier's low-pass filter directly or as full-range outputs.

Protection Circuitry With Status Indicator Lights: There are four status indicator lights on the top of the amplifier:

  • Power (Green): This LED lights green to indicate that the amplifier is turned on and operating normally.
  • Thermal (Red): This Red LED lights to indicate that the amplifier has exceeded its safe operating temperature, putting the amplifier into a shelf-protection mode, which reduces the power output of the amplifier. The red light will shut off and the amplifier will return to normal, full-power operating mode if the heat sink temperature drops back to a safe level.
  • Low Ohm (Amber): This amber LED lights to indicate that the impedance of the speaker load connected to the amplifier is lower than the optimum impedance load range for the amplifier. When this light is on, a protection circuit engages and reduces the power output of the amplifier. The amber indicator will also light when a short-circuit is detected in the speaker wiring.
  • Low V (Blue): This blue LED lights to indicate any dip in supply voltage below 8 volts.

Note: There is only one condition that will shut down the 1000/1v2 completely and that is if the battery voltage of your vehicle drops below 10 volts.

Controls

Simplified Gain Setting: The amplifier's R.I.P.S. feature also allows for easy gain setup. Because the amplifier will always deliver the same amount of power within its operational range of impedances and supply voltages, the maximum, unclipped output is very predictable. This makes setting the gain level of the amplifier via the input sensitivity control very simple. All you need is Digital AC Voltmeter (142TK12V, sold separately) and a Test CD Disc (503CD104, sold separately) with a sine-wave test-tone recorded at 0 dB reference level in the frequency range to be amplified for that set of channels (50 Hz for subwoofer channels).

Active Crossover: The Slash v2 amplifiers provide a comprehensive crossover network to fine tune your system effectively and accurately. The variable filter design employed in the Slash v2 amplifier crossover sections allow you to seamlessly switch slopes, easily change filter frequencies and address what frequencies the preamp outputs will pass. The 1000/1v2 offers the following crossover adjustments.

  • Filter/Slope Mode: The amplifier features low-pass 12dB/octave Butterworth or 24dB/octave Linkwitz-Riley alignments allowing for more precise integration of subwoofer. You can also turn the amplifier's filter mode off.
  • Variable Frequency: The amplifier offers fully-variable frequency selection from 40-200 Hz on subwoofer channel filters with a detented frequency selection potentiometer for precise adjustment by sight or feel.

Bass Controls: The bass control functions on the JL Audio subwoofer amplifier include the following.

  • Variable Bass Boost: The amplifier's variable bass boost features a single, parametric band of equalization with variable "Q" (0.5 - 4.3), center frequency (20 - 80 Hz), and boost (0 to +15dB).
  • Infrasonic Filter: This filter is a defeatable, fully-variable 24dB/octave infrasonic filter with adjustable cutoff frequencies from 15-60 Hz. Ultra-low frequencies that cannot be reproduced by a subwoofer do not become sound but become unnecessary oscillations, which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to speakers. Setting the Infrasonic filter switch between 15-60Hz cuts the frequencies below the respective frequency to improve the reproduction performance of the speakers by eliminating harmful distortion.
  • Remote Bass Port: The amplifier is equipped with a connection for a wired Remote Bass Control (136RBC1, sold separately) that allows fully variable boost control from the front of your vehicle.

Output Polarity Switch: Depending on the distance relationship of your mid-bass speakers and your subwoofers in your car audio system, it can be desirable to reverse the polarity of the subwoofer system in order to produce a better transition between subwoofer and mid-bass speaker output. The amplifier's Output Polarity switch allows you to perform this polarity inversion with a flip of a switch without removing any wires.

Connections

Power and Ground: The JL Audio amplifier's set-screw Power and Ground connections are designed to accept 4 AWG power wire.

Remote Turn-On: The Slash v2 amplifier's set-screw turn-on lead will accept 18 to 8 AWG wire.

Speaker Outputs: The 1000/1v2 amplifier's set-screw speaker terminals will accept 16 to 8 AWG speaker wire.

Preamp Inputs: The amplifier features one set of differential-balanced RCA jack inputs. The amplifier's input level can be set to Low (200mV-2V RMS) when connecting the amplifier to a low-level preamp signal or set to High (800mV-8V RMS) when connecting the amplifier to a high-level speaker signal.

Preamp Outputs: The amplifier also features one set of preamp outputs so you can send audio to another amplifier in your system. The preamp output is switchable and can be set to a Full-Range, Amp Filter or Out Filter.

Note: All inputs, outputs and controls are located on the front side of the amplifier to make installation of the amplifier simple and neat.

Extremely high quality...

Written By Beau, Nashville, TN on Tuesday, September 29, 2009
 
This amplifier is one of the best amps sold today... The raw power that this thing produces is astounding, and it has many settings which can shape bass better than just about any amplifer made. Besides being a JL Audio quality product, one reason this amp is under rated and in a high-class category is that it will maintain over 1000 watts RMS of clean output with any normal voltage & also into 1.5 - 4 ohm impedances. I have this amp driving the CS312RG-w1v2 JL Audio enclosure (three 8 ohm 12" w1v2 subs wired together in a sealed box at 2.7 ohms)...This impedance makes for a higher amplifier damping factor than a 1 or 2 ohm load. I have the amp's gain at the halfway mark and on certain songs I can barely stand to sit in my Explorer- i mean it HOUNDS ! Buy the bass boost knob for it- you'll see why this amp is definitely one to buy... When you merely remove this thing from its box & plastic and feel its weight you'll be proud of your purchase. It's simply JL Audio quality at its finest.

SOO MUCH POWER

Written By kevin, Loudon Virginia on Monday, February 02, 2009
 
I got this amp and never looked back. It has so much power. I have it on a JL 10inch 3v3. the lights do dim but that is because there is so much power. the only thing was that it requires so much power that I had to get a more powerful alternator because it fried the old one. after that it is the best amp i have ever had and i have gone througt a lot of them. i also have the black one and it looks crazy.

Amazing

Written By quisp, Los Angeles, CA on Tuesday, November 11, 2008
 
This thing is just absolutely incredible. I originally got the 500/1 since I was unfamiliar with how powerful the JL Audio line might be. I have a single 12w7. The 500/1 is pretty outstanding to be sure and made my windows flex while giving me a back massage in the process. The only problem with the 500/1 was that at the very top when I really wanted more it would distort. Although happy with the 500/1 I decided to trade it in for the 1000/1. I have never heard anything in my life get that loud while remaining clear and undistorted. The power is absolutely fantastic, so much so I can not stand it in my car. Buy this amp and you will be happy.

WHAT!!!

Written By Bama Boi, Tuscaloosa, AL. on Sunday, September 28, 2008
 
I have this big boy installed in my Avalanche powering 2 12" JL Audio subs.
I can say it's definitely putting out 1000 watts unlike some other brands
that are putting out less than what it says it does. If you want quality I
then go ahead and spend the money and get what it's worth out of this
amplifier. Great job JL AUDIO.
