JL Audio Slash v3 Monoblock Class D Subwoofer Amplifier


JL Audio Slash v3 Monoblock Class D Subwoofer Amplifier

The original Slash amplifier set new performance standards for automotive amplification and became the best-selling premium mobile amplifier in history. The new Slash v3 amplifier is built on this legendary pedigree and technology platform, enhancing it in a variety of key areas; like radically improved thermal performance, a beautiful new black look with powder-coated cast alloy heat sinks and dozens of tweaks aimed at improving performance, flexibility and reliability. 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. Its these improvements that allow the v3 20% more power than the previous generation amplifiers.

With the proper utilization of the R.I.P.S System, the JL Audio Slash 1200/1v3 offers a solid 1200 watts RMS at any load between 1.5-Ohms to 4-Ohms with any voltage draw between 11V and 14.5V. To smooth out that power to your liking, the amplifier provides a very complete set of signal processing features, including a parametric bass EQ and fully variable infrasonic filter. There is no magic and no guesswork here... just pure technology, refined to the last detail.

Unparalleled Signal Processing

Unparalleled Signal Processing

Highly advanced crossover filters and a full complement of signal processing features offer ultimate control and flexibility. Its this control and flexibility that sets the Slash v3 apart from heartless amplifiers that care only about putting out brute power. A variable low pass filter with selectable slope allows the user to tune the driver in perfectly to its environment and filter out any unwanted harmful frequencies. The highlight of the 1200/1v3 is its Advanced Bass Control Section consisting of two primary components; a fully variable 24 dB per octave infrasonic filter and a parametric, single-band equalizer.


R.I.P.S. System

R.I.P.S. System

The 1200/1v3 employs JL Audio’s exclusive Regulated, Intelligent Power Supply (R.I.P.S.) design. This sophisticated power supply allows the amplifier to produce its optimum power (1200 watts x 1) over a wide range of speaker impedances. Unlike conventional amplifiers that require a specific impedance to produce optimum power, the R.I.P.S.-equipped 1200/1v3 gives you the freedom to use a variety of subwoofer configurations without sacrificing power output or sound quality. The operation of the R.I.P.S. circuitry is entirely automatic and adjusts itself every time the amplifier is turned on according to the lowest impedance present at the speaker load.

Slash 3 Review

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

I recently helped build my buddys system. He is using 2 of these on 2 W7 12s. Sounds great, no complaints except the HEAVY pricetag. Amp is durable and sounds absolutely amazing. He could have saved alota$ buying RFosgate i think, but it wouldnt sound as clean. If you want really loud and pretty clear get RFosgate. If you want loud and really clear get the JL. These things imo should be about 550$ would be a good price. My buddy just has alot of $$$. I personelly run W7s and Fosgate gear. Always jl speakers and fosgate amps i have found the best. Better have an xs power battery and atleast a 200amp alt as well cuz the Jl sucks alot of juice.

Quality sound

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

I have alpine SPR-60C in my doors and back panels, with a JL 300/4v3 running the high end. The low end is run by two JL 1200/1v3, each amp powers 1 alpine type X 12" sub. This is one of the cleanest sounding systems I have ever had. Lots of base, and I haven't even punished the subs yet. I still have to put in my 250 amp alternator.

JL Audio 1200/1v3

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

This amp is a monster it sounds clear and clean and will pump massive bass that's unexplainable and it needs a lot of power, it is expensive but its worth every dollar and will last for years and will not back down from no subwoofer it will blow any sub that has a weak voice coli this amp is built by the best audio company period, I had the 1000/1v2 and the v1 and they are out of this world, but i suggest a high output alternator and a deep cycle battery or your car won't last a week, and 0 gauge wire only, the best amp on the planet is back in black.

Great Amp

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

I have one of the old versions of this amp and it smoked 12 12 subwoofers in a month. I have this thing pushing two pioneer ts-w5102spl and it does not back down. would recommend this amp.

Awesome amp real power

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

Awesome amp. I didn't buy from sonic got it at my local shop which is an authorized jl audio dealer. Before this amp I had the hifonics brutus 2000 watt amp. Nothing against that amp I think hifonics is an good amp I have a review for that on this site as well but there is a big difference in the sound coming from the brutus amp and the slash from jl. Sound quality is out of this world true pure real power. Gave a demo to my co-workers and they were amazed have it pushing 2 jl w6 12's which also are amazing. YOU will need to upgrade alternator and get a second battery it eat up some power!!! It's an beast heavy and durable and huge but have an 2003 mercury grand marquis all custom install amp rack and etc.

The best amp ever!

The following review is for 1200/1v3, which is a part of the bundle you are viewing.

I've got the Slash 1000/1 and it is every bit of what I wanted from an amp. It's regulated power supply allows this amp to push the same amount of watts no matter what impedance you are running at. Fully loaded with all the features of any modern amp except JL has been making this amp for over 15 years and it is still 1 of the best selling amps of all time. I'm running mine at 4ohms and it barely gets warm after pounding for hours. It delivers clean power allowing you to push more of it w/ less noise at unwanted frequencies and getting the most out of your subs. I bought 1 of these way back in 2003 and it is all I will buy from now on until someone else makes something as good but I haven't seen it yet. It's aesthetically the best looking amp but it's performance is unparalleled. No longer do you need to wire down to the lowest impedance and squeeze every bit of power from your amp straining your vehicle and system. It's not necessary. If $ is not an issue just buy the right amp from the beginning and get the Slash, there's not a better option that I know of. Old school prices ($1 a watt) but Old School performance and an amp that'll last 20+ years.
