JL Audio Slash v3 4-Channel Class A/B Full-Range Amplifier


JL Audio Slash v3 4-Channel Class A/B Full-Range 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 Absolute Symmetry Class A/B output circuit employs identical N-Channel MOSFET transistors for push and pull with true buffering from the load impedance. This is accomplished via a patented circuit that reverses the operation of one of the transistors in each pair to achieve absolute power symmetry and extremely low distortion over a wide range of load impedances. 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 300/4v3 offers a solid 75 watts RMS per channel 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 fully variable crossover filters with selectable crossover modes (Off/LP/HP). There is no magic and no guesswork here... just pure technology, refined to the last detail.

Unparalleled Signal Processing

Unparalleled Signal Processing

The 300/4v3 employs two separate, but identical filter sections for its front and rear channel pairs. These sections consist of a x1/x10 Frequency Multiplier, 12dB/24db Filter Slope Selector, Crossover Mode Selector, and a Fully Variable Crossover Filter for ultimate control and flexibility. Its this control and flexibility that allows the 300/4v3 to work well for a multitude of system configurations. Whether you wish to run a traditional 4-Channel Setup, an "Active" Full Range System or a Bi-Amplified System the 300/4v3 has the controls necessary to filter out the unwanted harmful frequencies from your signal.


R.I.P.S. System

R.I.P.S. System

The 300/4v3 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 (75 watts x 4) 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 300/4v3 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.

Best kit money can buy

The following review is for XKIT44, which is a part of the bundle you are viewing.

This kit includes everything I needed for my 4-channel JL Audio amp. I love it. The look of the fuse holder is awesome and the braided cable protector is great under the hood too. The RCAs worked like a charm and I had plenty of speaker wire included. No complaints.

great

The following review is for XKIT44, which is a part of the bundle you are viewing.

Have not installed yet but it seems to be everything it claims to be. Did recomend itnto a friend but he didn't listen and spent way to much for a kitat a local best buy. Did a lot of research before I bought this kit and it looked like the best value for my hard earned money. Having not yet installed is why I didn't go all five stars. Soon it will be going into my 89 olds custom cruiser with 4 12s....

This wiring kit is the best I've used so far. It bends very easy in tight places and this is the size wire that I actually paid for. Don't waste $ on cheaper brands...NVX is AWESOME!!!
