300W RMS 4-Channel Amplifier + NVX 4-Channel L.O.C. + 4 Gauge Amp Kit
• RMS: 75W x 1 @ 4 ohm, 75W x 1 @ 2 ohm, 75W x 1 @ 1.5 ohm
• Total RMS Power: 300W
• R.I.P.S. (Regulated, Intelligent Power Supply)
• Dual N-Channel MOSFET power supply
• Absolute Symmetry™ Class A/B Circuit
• 13.4"L x 9.25"W x 2.36"H

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.
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.
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.

Awesome product for the price
I was overall satisfied with everything in the kit. The wire was great quality and easy to run. I liked that it came with a plastic grommet for my firewall. I think the fuse was really nice and looks great under the hood. Just make sure you have a 4 gauge crimping tool which I did not have. I ended up crimping with some pliers and a hammer to tighten up the terminals.

Good kit for the $
Used this kit to install a 4 channel amp and had plenty of wire to do the job.

good amp kit
The amp kit works well. The installation was very easy. I had plenty of wire. For the power and ground wires I soldered on my own copper lugs. The only real drawback is that this kit is cca instead of ofc, but that is why it is so cheap.

excellent value
this had everything you need in it to do an amp install. I was impressed with the speaker wire as it was a heavy gauge wire. 14awg I think. it was listed to have 20ft of speaker wire in product description but had 65ft in package, (nice). all the wire was nice and flexible (easy to work with) unlike some cheaper wire I've seen or used that's real stiff. couldn't ask for anything more.....

Worked Perfect
Great price and fast shipping. It was all I needed to hook up my amp and composite speakers. Plenty of length on all can cables.

Really Good Quality!!
Got this wiring kit at a discount after purchasing together with amp, so ended up at around $37. Ive bought 4 gauge wiring kits before at local radio shop for the same price, but not the same quality at all! The power and ground wire are super flexible, great for passing through firewall and bending around tight corners. Great quality anl fuse, and was surprised to find 20 ft of equally good, thick, speaker wire, just enough to rewire my whole car! And loved the 4 twisted rca cables that make install a breeze, and helps keep everything looking neat and clean. Perfect for a 4 channel Amp Install.
