JL Audio's 1200/1v3 mono subwoofer amplifier puts out 1,200 watts RMS to your subs, so you'll enjoy powerful, moving bass in your car. Its patented Class-D amp circuitry delivers exceptional, natural sound with extremely low distortion, while a parametric EQ bass boost give you precise control over your bass. You can add the RBC-1 wired remote (not included) to dial in the right amount of thump from the front seat.
This Slash v3 amplifier isn't just powerful, it's smart. As your car system's 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.
The 1200/1v3 uses "differential-balanced inputs" to isolate the signal's ground from the chassis ground, reducing noise and making this Slash v3 amplifier compatible with almost any system, including most factory radios. You can adjust the variable infra-sonic- and low-pass filters to maximize the performance of your subwoofers.

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.
Without a doubt, one of the finest subwoofer amplifiers I have ever owned. I'm sure the up front price will cause a lot of average consumers to shy away, but this is a case of truly getting what you pay for. As head units become more and more simplified and lose features (fully active crossovers, etc.) it's nice to have a solid subwoofer amp that can be dialed in precisely.
Also, to the other reviewer who blew a fuse at the distribution block? You might want to re-check your power wire and setup. I've been running my amp for just over a year with a overall 150AMP fuse near the battery, and another 100AMP fuse about 12 inches away from the amp itself, and have never had a single problem with fuses blowing.
This amp originally powered two 12w6v3 subs, and everything sounded absolutely incredible. I've since gone to a more "compact" setup comprised of a single Fi Q 12" sub in a sealed enclosure, and it sounds stellar. If you have the cash to pony up for this amplifier, you won't be disappointed. As consumer electronics get cheaper and cheaper, it's nice to have an amp like this made of top-shelf components.
Pros: Clean Power, Precise Crossover Adjustments, Powerful Bass EQ and Q Features
Cons: Price, Size
I have this amp with two new JL W6v3 12" subs and I haven't even turned the sensitivity up due to the fact that I'm breaking in the subs, and my lights are dimming down to almost off and I blew the distribution block 100amp fuse. I'm definitely gonna have to get a better battery and new alternator. Just an amazing amount of power.
Cons: Nothing! Besides your probably gonna have to get an alternator and deep cycle battery.

Mono Subwoofer Amplifier: The JL Audio 1200/1v3 is a class D monoblock subwoofer amplifier. With its regulated power supply, the rated output is 1,200 Watts RMS x 1-channel into a load of 1.5Ω to 4Ω, with an input voltage of 11V to 14.5V. The signal to noise ratio is >95 dB and a total harmonic distortion is <0.05%, both measured at rated power (1,200 watts RMS). The amplifier's frequency response is 5-250Hz. (It is not designed for driving full range speakers.)
R.I.P.S. (Regulated Intelligent Power Supply): The JL Audio R.I.P.S. system ensures consistent power delivery over a wide range of battery voltages and load impedances, providing the rated power output at any impedance from 1.5Ω to 4Ω and at any vehicle voltage from 11V to 14.5V.
RealSink Heat Management: This Slash v3 amplifier features a real cast-alloy heat sink with vertically-oriented fins, very effective at dissipating heat from the amplifier via convection and radiation. This design is achieved through extensive finite-element analysis, resulting in an amplifier that keeps cool under the most demanding conditions. As an added cosmetic benefit, the cast-aluminum end-caps replicate half of a heat sink fin so that when two or more amplifiers are mounted end-to-end, you get a seamless custom look.
Advanced Rollback Protection: If a Slash v3 amplifier should ever reach an unsafe temperature, the Advanced Rollback Protection circuit reduces power until the amplifier cools down, without turning the music off completely.
Class D Circuitry: JL Audio's Patented Class D output circuit utilizes a discrete control section and a unique feedback loop design, resulting in a damping factor greater than 500 at 4Ω (>250 at 2Ω), higher than most other Class D and Class A/B designs. The benefit is tight, clean bass reproduction with the efficiency advantage of Class D.
Differential-Balance Inputs: The 1200/1v3 features differential-balanced input architecture to reject noise and ensure compatibility with a wide variety of source units, including many OEM systems. Without using a line output converter, you can connect most OEM or aftermarket source units to the amplifier without creating any noise or compatibility issues.
Note: You will need a speaker wire to RCA adaptor (item number 136XDCLR2S, sold separately) when using a speaker-level input.
Preamp Outputs: The preamp outputs make connecting multiple amplifiers simple. The 1200/1v3 features an independent crossover for the preamp output with frequency (40-200 Hz), mode (Full Range, LP, or HP) and slope (12 or 24 dB) adjustments.
Protection Circuitry With Status Indicator Lights: There are four status indicator lights on the top of the amplifier:
Infrasonic Filter: Ultra-low frequencies that cannot be reproduced by a subwoofer do not become sound, but unnecessary oscillations which affect sound by causing distortion. These frequencies also waste amplifier power and can cause damage to speakers. Using the infrasonic filter, variable from 15 Hz to 60Hz, removes the signal below the setting to improve the performance of the speakers by eliminating harmful distortion. The infrasonic filter can be turned off.
Simplified Gain Setting: The amplifier's R.I.P.S. feature allows easy gain setup. Because the amplifier always delivers the same output power within its operational range of load impedance and power supply voltage, the maximum, unclipped output is predictable. This makes setting input gain very simple; you'll need a Digital AC Voltmeter (sold separately) and a CD with a sine-wave bass test tone recorded at 0 dB reference level (item number 503CD104, sold separately). In addition to the continuously variable rotary gain control, the Input Voltage switch adjusts the gain range, set to Low (200mV-2V) or High (800mV-8V).
Low Pass Crossover: The built-in crossover allows you to adjust the frequency and filter slope of the amplifier's powered output:
Preamp Output Crossover: An independent crossover address what frequencies the preamp outputs will pass:
Advanced Bass Controls: The bass control functions on the amplifier include:
Output Polarity: Depending on the distance between the mid-bass speakers and the subwoofer in your system, it might be preferable to reverse the polarity of the subwoofer to produce a better transition between the two. The Output Polarity switch allows you to quickly reverse the subwoofer's polarity (0°/180°).
Power and Ground: The amplifier's set-screw Power and Ground connections accept up to 4-gauge wire (4-gauge minimum is recommended).
Note: The Amplifier is not equipped with a fuse. An external 100-amp fuse (not included) must be installed on the power wire. If the system has only this amp and a wiring kit is used that includes a fuse with a value other than 100-amps, the original should be replaced with a 100-amp fuse.
Speaker Output Terminals: The two pair of set-screw speaker terminals accept 12-gauge to 8-gauge wire. The terminals are internally shorted together, making it easy to connect two subwoofers.
Remote Turn-On: The set-screw turn-on lead terminal will accept 12-gauge to 8-gauge wire.
Note: If your headunit does not have a dedicated remote turn-on output, the amplifier's turn-on lead can be connected to a switched +12V volt circuit.
Preamp Inputs: The amplifier features one set of differential-balanced RCA 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 higher voltage preamp or speaker-level 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 can be full range, or the built-in crossover can be applied.
Note: All inputs, outputs and controls are located on the front side of the amplifier to make installation simple and neat.
