JL Audio's XD800/8v2 amp packs a wallop far beyond what you'd expect from something so small. This compact 8-channel amp plays your music with true fidelity and impressive impact, without straining your car's electrical system. A cast alloy heatsink and an advanced cooling system keep this amp at optimal temperature, eliminating thermal shut-downs so your music keeps going strong without interruption.
You can set up this versatile amp for just about any system so you'll never outgrow it, no matter how your audio plans may change. It can:

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.
Superb amp gives me exactly what I was looking for. Powers JL 6.5" in front doors and rear side panel (75 watts each), and a pair of 6.75" Kicker Subs in the rear deck (150 watts each (bridged). Perfect amp for my 2004 Pontiac GTO. Great job JL!
Pros: Design, quality, flexible input and output options, bridgeable, lower power consumption than my old 600 watt amp.
Cons: None to speak of.

8-Channel Full-Range Amplifier: The JL Audio XD800/8v2 is an eight-channel, Class-D amplifier utilizing NexD ultra-high speed switching technology to deliver outstanding fidelity and efficiency. The amp can be operated with a wide variety of source units and system configurations.
Specifications: The XD800/8v2 is rated at 75 watts RMS x 8-channels at 14.4 volts, measured into 4Ω from 20 Hz to 20 kHz with no more than 1% THD+N. The bridged output is 200 watts RMS x 4-channels at 14.4 volts, measured into 4Ω from 20 Hz to 20 kHz with no more than 1% THD+N. Each pair of channels (1&2, 3&4, 5&6, and 7&8) is independently bridgeable, so the amp can be used in 8-channel, 7-channel, 6-channel, 5-channel, and 4-channel mode. The 2Ω output is 100 watts RMS x 8-channels at 14.4 volts, measured from 20 Hz to 20 kHz with no more than 1% THD+N. The Signal to Noise ratio is 104 dB at rated power and 84 dB at 1 watt, both A-weighted, 20 Hz to 20 kHz.
NexD Class D Technology: NexD is a switching amplifier design that combines exceptional audio quality with excellent efficiency and less complexity. This results in an affordable compact amplifier with exceptional audio quality and total efficiency.
Advanced Rollback Protection: The XD-Series amplifiers employ advanced thermal and low-impedance protection to virtually eliminate annoying amplifier shut-down events. Should any XD-Series amplifier overheat, its intelligent, unregulated power supply reacts by limiting available peak voltage until the amplifier returns to a safe temperature range. Likewise, if an impedance lower than optimal for the amplifier is present at the outputs, the XD amplifier will roll back peak voltage to protect itself without shutting down.
Differential-Balanced Inputs: The amplifier features differential-balanced input architecture to effectively control noise and ensure compatibility with a wide variety of source units, including many OEM systems. Without resorting to line output converters, you can directly connect most OEM source units to the JL Audio amplifier without creating any noise or compatibility issues. Unlike conventional single-ended inputs, the differential-balanced design does not connect one side of the audio signal to chassis ground. This eliminates any voltage sensitivity between one input terminal and ground and greatly reduces the incidence of alternator whine in a typical car audio installation.
Note: You will need up to four speaker wire to RCA adaptors (136XDCLR2S, sold separately) to connect this amplifier to your headunit via speaker-level.
Protection Circuitry with Status LED: There is a single multi-color LED on the top panel to indicate the amplifier's operating status.
Cooling System: The outer shell of the JL Audio amplifier is designed to remove heat from the amplifier circuitry. For optimum cooling performance, this outer shell should be exposed to as large a volume of air as possible. Enclosing the amplifier in a small, poorly ventilated chamber can lead to excessive heat build-up and degraded performance.
Control Panel Cover: The XD800/8v2 features a Control Panel Security Cover which protects and hides the amplifier's controls. When installed, the cover ensures that the amplifier's settings are not accidentally changed, while creating a clean aesthetic look for the amplifier and your installation. The cover is installed at the factory and must be temporarily removed for access the amplifier's controls. The security cover is secured by two 2.5mm Allen-head machine screws.
Gain Setting: The XD Series amplifiers have independent gain (input sensitivity) controls for each pair of output channels; in this case, 1&2, 3&4, 5&6, and 7&8. Using JL Audio's guided set up requires a digital AC voltmeter and a test CD (item number 503CD104, sold separately) with a sine-wave test-tone recorded at 0 dB reference level in the frequency range to be amplified for that set of channels (50 Hz for subwoofer channels, 1 kHz for a midrange application).
Input Voltage: The input voltage range is broken into two sub-ranges (the sub-range is set simultaneously for all inputs, but each pair of channels has an independent gain control to set the specific voltage):
Remote Level Mode: When the optional HD-RLC wired remote is added, use this switch to set which channels are affected:
Turn-On Mode: There are three options for turning the amp on, selected using the Turn-On Mode switch:
Crossovers: Each pair of channels (1&2, 3&4, 5&6, and 7&8) has an independent crossover, with its own mode and frequency adjustments under the removable cover plate:
Power/Ground/Turn-On Terminals: The amplifier features screw clamp terminals for the power, ground, and remote turn-on connections.
Note: The Amplifier is not equipped with a fuse. An external 80-amp fuse (not included) must be installed on the power wire. If a wiring kit is used which includes a fuse with a value other than 80-amps, the original should be replaced with an 80-amp fuse.
Speaker Output Terminals: The XD800/8v2's sixteen screw clamp speaker terminals will accept 16 to 8 AWG speaker wire. The included 2.5mm Allen wrench is used for making connections.
Preamp Inputs: The amplifier has four pair of differential-balanced RCA jack inputs; each pair has a dedicated gain control designed to match the input sensitivity of the amp to the specific signal source feeding it. In addition to preamp level signals, the RCA inputs are also used with speaker level signals (136XDCLR2S required and sold separately).
Remote Level Control: The amplifier features an RJ-14 telephone jack for adding an optional wired remote level control. With the addition of the optional wired remote (item number 136HDRLC, sold separately), you can control the volume of 2, 4, or all 8 channels of the XD800/8v2 from the front of your vehicle. This is useful for subwoofer level control or even as a master volume control for your system. If desired, multiple XD amplifiers can be controlled from a single HD-RLC controller using a simple phone line splitter and multiple phone cables (all sold separately).
Note: All inputs and outputs are located on one side of the amplifier to make installation simple and neat.
