JL Audio HD 5-Channel Class D Amplifier

JL Audio HD 5-Channel Class D Amplifier

JL Audio's Flagship Series of amplifiers offer unmatched performance from an ultra-compact chassis. These Class D amplifiers require less power, generate minimal heat and take up far less space than the common amplifier design. HD Series amplifiers reproduce your music with outstanding accuracy, providing high-fidelity sound even under the most demanding conditions, thanks to a number of JL Audio exclusive technologies. Single Cycle Control (U.S. Patent #6,084,450), R.I.P.S System and Advanced Rollback Protection are just a few of the technologies that sets the HD Series apart from the rest of the market, all designed to deliver top-flight audio performance. In addition, behind every HD's removable security cover, you will find studio-grade signal processing with fully variable crossover filters to properly tune in your setup and put all the technology under the hood to good use.

Also included are JL Audio's noise-killing, highly flexible differential-balanced inputs with remote level control capabilities for the subwoofer channel via the HD-RLC remote level control (sold separately).

Advanced Rollback Protection + RealSink

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.


R.I.P.S. System

R.I.P.S. System

The HD900/5 employs JL Audio’s exclusive Regulated, Intelligent Power Supply (R.I.P.S.) design. This sophisticated power supply allows the amplifier to produce high power 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 HD900/5 gives you the freedom to use a variety of speaker 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.

Notes from JL Audio:
  • ¹If you connect a load higher than 4? nominal per channel in stereo mode (or 8? in bridged mode), power will drop by half with every doubling of impedance above 4? stereo / 8? mono. If you connect a load lower than 1.5? nominal per channel in stereo mode (or 3? in bridged mode, the amplifier protection circuitry activates a “safe” mode which reduces amplifier power to protect the circuitry from failure (the LED status indicator on the control panel will light up amber to indicate that this has happened). See page 15 for details.
  • ²When connected to the amplifier, the HD-RLC operates as follows. At full counter-clockwise rotation, the audio will mute completely. At full clockwise rotation the level will be the same as if the HD-RLC was not connected at all. In other words, it operates strictly as a level attenuator.
  • ²The RBC-1 Remote Bass Control used with JL Audio Slash, Slash v2, e-Series, A-Series and G-Series amplifiers is NOT compatible with the HD Series amplifiers. If you attempt to connect an RBC-1 to an HD amplifer, the control will not work. You must use the HD-RLC controller.
  • ³We do not recommend the use of “copperclad aluminum wire” or “CCA” wire because this wire is significantly less conductive than pure copper wire. Only use pure copper power wire, such as JL Audio’s Premium Power Wire. Tinned copper wire (silver color) is acceptable as the tin-plating is only a very minor component of the wire.
  • ³The HD900/5’s “+12 VDC” and “Ground” connections are designed to accept 4 AWG power wire. 4 AWG pure copper wire is the minimum recommended wire size for this amplifier. Use of smaller gauge wire (including cheap wire that is fraudulently sold as 4 AWG wire) can create a fire hazard.


Power Specifications - Full Range Channels

RMS Power @ 4 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

100 watts x 4 channels
RMS Power @ 2 ohms

The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far.

If the final impedance of your speakers or subwoofers equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound.

75 watts x 4 channels
Bridged RMS Power

Bridging refers to combining two channels on an amplifier to create one channel with double the voltage and an increased power output. A 2-channel amplifier will bridge down to 1-channel and a 4-channel amplifier can bridge to create 2-channels. An amplifier is most commonly bridged to drive a subwoofer.

Remember, once you bridge two channels down to one its final impedance will be 4 ohms unless otherwise specified. This rating lists the RMS power created once an amplifier is bridged.

150 watts x 2 channels

Power Specifications - Subwoofer Channel

RMS Power @ 4 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 4 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.
500 watts x 1 channels
RMS Power @ 2 ohms
The RMS power rating is the measure of continuous power that an amplifier can output, or a speaker can handle. It is the most accurate depiction of real, continuous power that the industry has so far. If the final impedance of your speaker(s) or subwoofer(s) equals 2 ohms, this is how much power this amplifier will supply at that ohm level. The higher the RMS wattage, the more clean and loud your music will sound. The 5th channel on these particular amplifiers are usually dedicated for driving subwoofers.

Amplifier Specifications

Amplifier Series
This designates the series of the amplifier. Many amps are available in a litany of different wattage and channel configurations, but maintain consistent features throughout the product line.
HD (JL Audio)
Amplifier Class

An amplifier increases the power of the signal being fed to it by taking energy from its power supply and matching the signal but increasing its amplitude. Amplifiers use many different methods for converting these electrical signals and have been categorized into classes.

Class A/B: Greater than 50% of the input signal is amplified while the other percentage is “off”. These amplifiers have a small amount of current flowing through the output transistors all the time which almost eliminates crossover distortion. Class A/B has great sound quality but is not as efficient as class D. These amps are most commonly used to drive speakers.

Class D: Also known as switching amplifiers, class D amps have output transistors that are completely turned “on” or “off”. This means that when the transistors are on, there is almost no voltage across them but when they are off there is significant voltage but no current flowing through it which makes these amplifiers very efficient at the cost of sound quality. These amps are most commonly used to drive subwoofers.

Other Classes: You may see classes such as GH, bD, X, FD, etc. by some manufactures. These amplifiers tend to be either class A/B, D or a hybrid of the two but with improvements to their designs that can make them more efficient or offer better sound quality.

D
Number of Channels
Each channel on an amplifier will power one speaker using a positive and negative cable. There are various types of amplifiers, each designed to power a certain number of speakers. Monoblock amplifiers, also known as single channel, are designed to power one or more subwoofers. These amplifiers often have very high power ratings. On the other hand, multi-channel amplifiers power multiple speakers, usually at lower power ratings. 2-Channel and 4-Channel amplifiers can power car speakers or low powered subwoofers. Occasionally you might see a 5 or 6-channel amplifier that can power speakers and subwoofers at the same time. The most common setup is a monoblock amp to run subwoofers and a 4-channel amp to run door speakers. Check out our Knowledge Base for more information.
5
Total RMS Power Output
Total RMS power is measured by multiplying RMS power per channel by the number of channels, and is calculated at the lowest level of operating impedance.

RMS power is the amount of continuous power, measured in watts, that an amplifier produces is called RMS power. The higher the RMS figure, the louder and cleaner your music sounds.

The RMS output figure is much more accurate than the peak rating when comparing products.

900 watts
Maximum Input Gauge Size
This is the largest gauge wire that will fit into the power and ground terminals of this device. The lower the gauge number, the thicker the wire is. For example, a 4 gauge wire is thicker than an 8 gauge wire and thus has higher current carrying capacity. Always do your best to get this size wire to reduce the risk of damage to your components.
4 AWG
Minimum Impedance Unbridged
The lowest impedance the amplifier will handle when it is not bridged.
1.5 ohms
Minimum Impedance Bridged
The lowest impedance the amplifier will handle when it is bridged.
3 ohms
THD at Rated RMS Power
The amount of change in harmonic content of the signal as it is amplified. A lower figure indicates less change and a more accurate amp. THD below 0.10% is inaudible.
.03%
Speaker Level Inputs
Speaker level inputs are commonly referred to as high-level inputs and vice versa. This input type allows you to get your audio signal directly from the speaker wire in your vehicle, instead of using RCA cables. The advantage of this is factory integration, as most stock radios do not have RCA outputs to run amplifiers.
Yes
Preamp Outputs
Many amplifiers are equipped with RCA preamp outputs which pass the original music signal from the source to additional amplifiers. This is known as daisy chaining because the source connects to the first amp, and the first amp connects to the second amp, etc. The advantage to daisy chaining is you only need one 2-channel RCA cable to transfer the signal from the head-unit to the amplifier, and then one additional cable for each amp being daisy chained.
No
Built-in Crossover

A crossover is a type of filtering system that permits only certain frequencies to play. A Low-Pass (LP) crossover allows only frequencies below its setting to get through which is good in the case of some subwoofers. A High-Pass(HP) filter allows frequencies above its setting to pass through, this is normally used on speakers.

When a crossover is set to FULL it means no filtering is added and the full frequency spectrum is allowed through the amplifier. Filtering is important because feeding a speaker frequencies it cannot reproduce effectively creates distortion.

Low-pass (LP)
High-pass (HP)
Full (AP)
High-Pass Crossover Frequency
The high-pass crossover frequency can be a fixed crossover point or a variable crossover range. A variable high-pass crossover allows you to select a specific crossover point which allows frequencies above the set crossover point to pass, while making frequencies below the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Low-Pass Crossover Frequency
The low-pass crossover frequency is typically used for subwoofers. It can be a fixed crossover point or a variable crossover range. A variable low-pass crossover allows you to select a specific crossover point which allows frequencies below the set crossover point to pass, while making frequencies above the set point gently or harshly roll-off, depending on the steepness of the slope.

The steepness of the roll-off slope is measured in dB/octave and refers to the rate of attenuation (lowering of volume) outside their pass bands.

50 - 500 Hz
Subsonic Filter
Allows you to block (filter) ultra-low frequencies that your subs cannot reproduce.
Switchable Off/30 Hz
Signal-to-Noise Ratio
This spec compares the strength of the signal to the level of background noise. A higher value indicates less background noise.
108 dB
Bass/Gain Remote
If the amp comes with a bass/gain remote you will be able to control the level of your bass from your dashboard. Typically bass remotes also include a 16-20 ft. wire for installation.
Optional (Accessory required and sold separately)
Fan Cooled
A great feature to have if an amp generates a large amount of heat. Cooling fans can help regulate the temperature to prevent the amp from overheating (burning).
No
Fuse Rating
The amperage and the number of fuse(s) an amp requires.
60A X 1 In-Line Fuse Recommended
Strappable
Some amplifiers can be "strapped" together in order to increase the output of a single audio channel. These amplifiers feature RCA preamp outputs, allowing you to pass the signal directly from one amp to the other to ensure consistency.
No
Sonic Certified Amplifier
Sonic Certified amplifiers have been tested by the experts at Sonic Electronix to meet or exceed the wattage ratings provided by the manufacturer. If this is marked as Yes, then you can trust the wattage ratings. If marked as No, then we have tested the amplifier and it did not meet the advertised wattage ratings. If marked as Not Tested, then the Sonic Electronix experts have not yet been able to test the amp.

BAD A**!

January 5, 2013

I have built many systems over the years and was faced with the dilemma of space in my C5 Corvette... there isn't any! While researching amps, visiting various forums I came across the HD9000/5. I never would have believed what this little jewel was capable of until I bought one and installed it. I currently have it driving two Boston 10" G-1104 of the sub channel, a pair of Boston Acoustic 6.5 Pro series on the front and a pair of MB-quart 6.5 QVL's bringing up the rear. The sound is awesome. I would highly recommend this AMP to any one looking for one amp to do it all. Well worth the price thank you Sonic.

May 15, 2013

I installed this amp in the rear area of a 2003 Ford F150 Harley edition. It is small enough to be entirely out of sight, it doesn't take any space I was using before, and it's a superb amplifier. If you're reading this review, just go for it. I really don't think you'll find a better value and I know you'll love it. Don't settle for some other amp you don't really want.

I chose this five channel amp to save space in my Ranger Supercab truck. It powers four speakers in the doors and a JL Audio 10 inch W/6 sub and and it is smaller than most high school textbooks. This amp amazes me every time I crank up the volume. The sound is clean and there is just so much power it's hard to believe it all comes from this little amp. It has a hefty price, but if you want great sound without a big stack of amps, you should consider the JL HD900/5.

JL Audio HD900/5 Review

February 2, 2010

I bought this unit and paired it with an Aline IVA-W505, Polk speakers and a JL W6 enclosed sub. The amp is absolutely clean way past reasonable listening levels. The highways in my area are horrible due to studded tires in the wintertime. This makes for a tremendous amount of road noise. The amp will drive the system cleanly past ALL road noise which is just incredible.

I highly recommend the product. When I sell my car the amp goes with me!

June 14, 2013

This amp just stomps. It's running a pair of JL C5-653's in the front, a pair of JL-C5-650's in the rear and a single JL 10W7AE sub. This amp keeps the system simple and it sounds incredible! No new alternator, battery or caps required. The amp is tiny, so I was able to mount in behind a panel in rear hatch area. It's the perfect amp for someone who wants a quality system, but wants to keep it simple. My system is plenty loud with accurate, clean and stable sound. So far the amp has been trouble free. It gets pretty hot, but i would expect that from a class D amp. Nothing unusual though. Can't say enough about the performance of this amp! The amp is a little spendy, but you have to remember is a full system amp. It's doing the work of 2 decently powered amps. 900 watts of truly clean power for accurate music reproduction.

I own a 2010 Grand Caravan. I just installed the JL Audio HD900/5. It is powering Boston Acoustic Pro Series 60 in the Front and Pro Series 50 in the rear. I am running a JL Audio 10" W3v3 in a ported Enclosure on the fifth 500 watt channel. I played my system for my two Teenagers 18 and 17. They said it sounds like a concert at the Bell Center. (Home of the Montreal Canadiens) There is no bigger compliment!

I'm using this to power 2 sets of JL Audio ZR650-csi speakers, and a Kicker CVT-10 subwoofer. I think these HD JL Audio amps are among some of the best amps made. They're small, run very cool and don't require a lot of mounting space, super flexible, powerful, and they sound great. I would recommend this amp or any in the HD line to anyone.

I cannot believe how powerful this amp is for its size. It is so compact it fits under my front seat without blocking the rear seat vents. The only thing I don't like it the lack of the Q, and the infrasonic dial has gone to a switch.

Great AMP

May 1, 2012

This AMP is outstanding. 5 channels and all that power. I got it for use in a jeep where I don't have the room for seperate amps for front speakers and subs. The sound quality is exceptional and it drives my dual 12 W3's perfectly. It is a little pricey when compared to other 5 channel amp (ie the alpine), but i think worth the extra money.

Best 5 Channel Amp out there... PERIOD

May 30, 2012

I've had everything from Soundstream to Polk Audio amps in my car and have had nothing but headaches with them... I put in one of these last year and I'm so happy to be done with all of that! This thing is powerful, sounds great, is suuuper compact and can be mounted just about anywhere, and it stays cool and doesn't miss a beat! I have this baby running 4 Focal Polyglass 165 VB components and two Diamond Audio DS3 10" Subs... in my Scion XD.... The Sound is Phenomenal!!!

People giving this a high ranking should also give a high ranking for Value... You get what you pay for and my experience is that is especially true for this amp vs any other 5 channel amp out there.... It's simply the best.

One of the Best Amps I have ever owned

November 25, 2011

I am in love with the power in this tiny package. For this reason it is the best amp I have ever owned. I like stealth installation and this baby makes it possible. This tiny little monster delivers a punch of clean hard power. This thing is low profile, sleek and stacks with their JL kit with other HD amplifiers. The only thing I didn't like was that it doesn't have RCA signal outputs; this is the only reason I didn't give it a 5 in every category. I understand its not having speaker level inputs in order to save size. If you have little space and need power, this is it!!

Amp rocks!!

March 20, 2012

I used this to push two 8" Wet Sound tower speakers, two 6-1/2" Wet Sound inboat speakers, and 500 watts to the JL 12" sub. It has plenty of power and sounds great!!

Excellent Product

August 31, 2012

I purchased this amp to save on space & money , by using only one amp, which is mounted under the RF seat. There is definitely more than enough clean power to drive a 12'' JL sub & Boston Pro speakers. The sound quality is excellent at all listening levels & I highly recommend this product.
