JL Audio XD400/4v2

JL Audio XD400/4v2 - XDv2 Series 4-Channel Class D Full-Range Amplifier

This potent 4-Channel amplifier employs JL Audio's high-speed NexD™ switching design to achieve unprecedented efficiency and amazing power output in an ultra-compact chassis. Don't let the small size fool you, though... this amplifier is capable of serious power, delivering a full 400W of continuous total power into a 2 ohm load (14.4V, 1% THD). Targeted specifically for an audiophile-grade four satellite system, the XD400/4v2 includes a variable mode low-pass/high-pass filter with a continuously variable cutoff frequency selection from 50-500 Hz. The XD400/4v2 also features the v2 Spec feature set, which consists of automatic turn-on capability (via signal sensing or DC-offset sensing), and a dual-range differential balanced input section able to handle a wide range of input voltage levels. With the addition of an HD-RLC remote level control (sold separately), you can control the volume of one or both channel pairs of the XD400/4v2 from the front of the vehicle. This amplifier features a black powder-coat finish and a gasketed, brushed aluminum cover for the controls.

Advanced Rollback Protection

JL Audio's signature Advanced Thermal Rollback protection system eliminates annoying thermal shutdown events to keep the music playing, even under the most demanding conditions. Should the amplifier reach an unsafe operating temperature, a special circuit rolls back peak power output, without changing gain, until the amplifier cools down to a safe operating temperature. The red "Thermal" LED will light to indicate this condition has been reached. Once the amplifier cools down, the circuit restores full peak power output and the red "Thermal" indicator reverts to its normal state. The operation of Advanced Rollback Protection is inaudible in most cases.


NexD Switching Technology

From the same minds that gave us the technology found in the 'Slash' amplifiers, JL Audio has taken the simple fixed PWM design approach and enhanced it with a very high switching frequency. Full-range NexD™ amplifiers and channels feature a variable, ultra-high speed version of the NexD™ technology (switching at well over 400 kHz). In these designs, a self-oscillating modulator with "feed-forward" sends information about the instantaneous power supply voltage to the modulator, combining this with the input signal to cancel out any distortion due to supply voltage fluctuation. This reduces distortion prior to applying feedback, simplifying the overall feedback loop design.

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....

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.

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

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!!!
