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

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

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 4Ω nominal per channel in stereo mode (or 8Ω in bridged mode), power will drop by half with every doubling of impedance above 4Ω stereo / 8Ω mono. If you connect a load lower than 1.5Ω nominal per channel in stereo mode (or 3Ω 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.

BAD A**!

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.

Bad a**

Just do it, buy this amp, it's the only amp you'll need. Installed in a 2012 f150 supercrew with CL441dsp, C5 5.25X & C5 tweeters on all the doors. Two tw3 10's awesome the best sound

Great amp

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.

Phenomenal Amp

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.

Great product

I purchased this JL Audio HD900/5 amp because it had the option to power four door speakers along with a sub woofer. It works great. I have it powering the four speakers in the doors and have the 5th channel powering the sub in the back.

POWERHOUSE

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.

Impressive!!

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.

JL Audio HD900/5 Review

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!

Small and powerful

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 !!!!!

Small Amp that packs a big bunch !!! Took up 65% less real estate then my two old slash amps . Replaced 300/4v2 and 250/1v2 .
I gained room and a improvement in sound quality the extra amps really makes a difference .Sounds great even at lower volume

Breathtaking Sound

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!
