JL Audio HD900/5 Amp Dyno Test and Review [4K]

[@nbrowser]

And this is why some car audio amplifiers are better than others! I remember back in the late '90s/2000s when setting up IASCA competition systems for SQ, you wanted amps that had tightly regulated power supply sections because the stability of output power does indeed affect RTA curves in repeated testing. I guess this is a reason I refuse to use cheap amps in my systems to this day whether the system be in my truck or my home. Quality amplification is where it's at!

[@wal]

Great point

[@msh6865]

For those that think this amp is overpriced, you're paying for the research and development that goes into a proprietary design. Meaning, you don't get an amp like this from some generic buildhouse. There are no cheap copies or clones of this amp available. If you want to pay less then you can find something cheaper that will do the job. But, it won't have the same technology and will be of lesser quality. Not saying a cheaper amp won't suit your needs but, in this case you truly do get what you pay for. For me personally, the only downside to this amp is the country it is made in. Excellent review Dereck!

[@joseluisruiz3789]

Nice, man! That R.I.P.S. (Regulated Intelligent Power Supply) Technology is Why Their Amps Are Pricey. You can get your promised power output from as little as 11 volts to 14.4 volts. The downside is that if you put more voltage power to it, it won't make a difference to give you more power like other amps. But for systems where you can't add extra batteries or High Output Alternators I think this is a win. So many people have argued with me on my other youtube channel over this but im glad you made this video to show what these HD amps can do. The sub amps like the HD750/1 HD1200/1 and even this one here on the video give you more power at 2 ohms vs 4 ohms or 1.5 ohms. I need to bring those dudes who were putting these Amps down to your channel so they can see exactly what you just showed. 😎👊

[@mikemarkel9203]

But where the RIPS amps shine is in their efficiency %. They usually run much higher than unregs do.

[@msh6865]

Well said. I think a lot of people are hung up on price versus the quality and uniqueness of JL amps. They offer several different amps across a variety of price ranges. Their RD amps for example are very reasonably priced and feature unregulated power supplies. Great value amps.

I have been running this 900/5 amplifier since 2017, its excellent! I paired it up with a JL Tweak88. Amazingly you can get digital optical audio from a stock Ford SYNC headunit with a PAC adapter that has a TOSlink output! unbelievable how good you can tune things with Tweak88 and a laptop, and get some excellent sound from a stock headunit. I was a car audio installer back in the 90's, and I never imagined the equipment would get this good. I run 2 JL Audio 8w3v3 subs, and a custom component kit with big Hertz ML 280.3 tweeters and some fancy front door speakers (I honestly forget what they were lol). The crossovers are high pass for tweeters in custom pods, bandpass for door midrange speakers, and lowpass for the subs, with the TweaK88 running 6 channel to the amplifier.

[@Van1018s]

I have always, for about 25 years, been a huge JL audio fan. I was a JL audio dealer from 96-02. I had a vehicle I competed SPL in IASCA with 12 500/1 and 12 15w3. I had a vehicle I competed IASCA in the pro 301-600 class and placed 9th, 7th, and 6th, in the world in 98,99,2000 using JL audio subs. I own this amp. Purchased brand new direct from JL audio, and it did not work out of the box, so obviously zero quality control or testing was done. They did promptly send me a call tag and immediately got me out a new amp, which worked perfectly. Kinda. I have it running a c5 component set in front, c5 coaxial in rear, and a single 12 w3. The entire amp is run at 4 ohm. I can tell you it is very efficient. My stock charging system with the big 3 upgrade maintains 14.2 volts at max unclipped volume. The lack of dynamic power makes this amp very not “musical”. Is it unique? Yes. Will it hold its value well? Yes. Do I like it? Hell no. As I said the lack of dynamic power makes it seem very underpowered. At moderate-high volume, but still 2-3 volume notches below clipping it overheats and goes to like a limp mode after about 30 minutes. Listening to rock. Not rap or heavy bass songs. It still makes sound, just zero bass and low volume until it cools down. It is in a well ventilated area and keep in mind I’m maintaining over 14 volts and the amp is running at 4 ohm. I could go into more detail, but I’ll just say compared to what else is available I would personally not recommend this amp. If it was $500 maybe. $1249. No way. Just my 2 cents.

[@skofdoggy]

So what would you recommend thats 5 channels, same wattage as this but better? Eh?

They sound great and can be purchased for a lot less than their advertised MSRP at a good local dealer (some are more willing to deal than others).

Basically they are all the same general form factor, highly efficient, and sound great! Loved that the PDX and JL were designed to easily be "stack mounted" if needed.

And then you put it in a car. Never understand this...who cares? If it was going into a studio environment then great...but its going in a pickup or Jeep or Hyundai.

[@jasonliss2644]

The best thing I see in this design is flexibility. You get 1200 watts from 1.5-4 ohms. This makes this amp useful over multi car installs. You change subs, you are not stuck with choosing a particular ohm rating to get desired wattage. With so many amps being the same underneath, the labels and heat sinks only separate them. Yes, it has a higher than normal price point, but the beauty is its flexibility. To me as an old school guy working on an daily SQ built, I see the value.

[@damon323]

Absolutely!! Plus its consistent power at all range of voltages also is a huge plus! Most standard amps only put out the rated watts at spec at 14.4V. Well what if your vehicle doesn’t? My 4Runner as well as a number of other Toyota’s alternator/voltage regulator fluctuates from 13.8v at startup. And then sits at 13.2v. That 1.2v difference doesn’t sound like much, but you end up losing a lot of output. With fluctuations, your stereo can sound great one minute, and then sound weaker the next.

All of us are waiting for those amplifiers since it's basically the cab 22

[@bobadingo]

Compared the JL HD 900 to the Alpine PDX v9 and the Alpine clearly was the better sounding amp, with a much cleaner audio output & absolutely zero distortion, and was compared back to back multiple times just to verify. as of now 10 years later the Alpine Is Still performing flawlessly, driving 14 speakers and a12-inch sub! This is surely a testament to the Alpine quality, durability and reliability.. .

[@jasonklemm8017]

Those PDX amps sound horrible to me. I've owned several, and they sound incredibly sterile. I've been running my entire setup on a JL HD900/5 and couldn't be happier with the output and quality of sound.

[@pwnedatcod]

Have you done the jl audio hd600/4 amplifier?

[@cartlopez4581]

hey great video!!! could you tell me which size are de four bolts ffrom de corners? m10 or 12?

[@Drsteezymcgee]

I've never had a sheet of paper that was 1.9" thick before 🤔

[@delvinchandler]

Lol

[@wal]

🤦‍♂️

[@Drsteezymcgee]

🤷‍♂️

[@michaelhollon5332]

At 1.9 inches thick wouldn't that be considered wood?

[@flight2339]

Someone got reamed here..he was pretty thick sheet 😂

[@zacychan1]

Had to watch a review on the amp I have in my jeep 🤣. This power supply is a big selling point in my buddy’s f150 now since his voltage fluctuates for his oem agm (raptor), see this a lot on new vehicles with fuel saver mode alternators. I’ve also heard these type of power supply doesn’t do great on a load like this? Same with amplifiers like the Mosconis?

[@mikemarkel9203]

I guess I'm lucky to have been out of the 12 volt industry just long enough that I didn't see this amount of junk come through the doors of our shop{meaning the knockoffs}. We only had to worry about things like DUAL or BOSS and we could just look it and kinda giggle inside to figure out how to tell the customer their stuff was junk. But then again almost anybody likes to say they're an Installer nowadays.

[@greggcleaver3282]

Saw an add for an RD 900/5 that was upgraded to an HD 900/5. Not knowing much about amps, would you recommend looking into it, or staying away. Thanks

[@greggcleaver3282]

Never mind the last question, seller put in wrong information.

[@BuildTheWallAlready]

I would love a video dyno test of the JL Audio RD 900. Please and thank you.

[@IRQ1Conflict]

I see you have some unifi 52 2.0's. How you liking them?

Can you do a dyno Test on a BavSound amplifier? That one would be amazing to get real results! 😭 thanks !

[@russsmith9042]

What's up Big D? Speaking of bespoke I got an old- school custom Linear Power 5002 wanted to know if you wanted to put it on the bench. As soon as I get it back from Ray at LP I would like for you to test it and see what this old beast will do. Of course only if you're interested. By the way I love watching your videos and where do you get the Amazer Lazer soundtrack or song or whatever it is?

[@damon323]

That is insane how much the sub channel put out at 2 ohms! I’m ordering the marine version of this cause I can get a good deal!

[@matthewmassey2333]

I have learned running JL Audio equipment you don't need a lot of power when the output of the amplifier is clean and dynamic 👌.

[@chriscomda]

What known brands are considered as copies? Would like to have some names.. please

[@cpufrost]

Solid amp with great loudspeaker control.

[@xLedezma]

W7 10" or 12" for 5th channel in hd900/5?

[@dicmccoy]

Is there a way to test the built in amps on Home Audio Subwoofers on your amp dyno, to see if they're putting out the power as advertised? That would be cool to see. Thank you for the awesome vids. Have you considered either of these songs from No Copyright Sounds for your playlist? 1 - Lost Sky "Fearless" 2 - Lost Sky, Chris Linton "Fearless Pt. II"

[@wal]

Absolutely and thanks for the tracks. Search for Polk audio, Yung and Dayton Audio Amp Dyno vids and you’ll see me testing the plates from these subs

[@dicmccoy]

@@wal I found the video. Thank you. It's too bad I live way up here in Canada or else I'd send you in one of my JL Audio Dominion D110's to test the power output of the plate amp to see if it does it's rated 750 watts.

[@SDG-cv4br]

How does the fuse work? The manual says it requires a 60 amp inline fuse but all the test show it pulled more than double that (I saw 152.4 @ the 9:42 mark).

[@wal]

So I ran all channels full range which is unlike most people would use the amp. Worst case scenario on the amp

[@jeremybreeden4228]

Hey Big D I really enjoy all of your videos man. You're channel Inspired me to start finding out the actual RMS power the Amps I come across when doing installs for people who are Interested in knowing exactly what their amp is capable of as well. Have you ever put a Memphis Audio viv900.5 on the Dyno? I'm just wondering because I'm looking into getting one for a good price and just wondering if it puts out it's rated Power. Keep up the good work man I'm sure your videos has saved a lot of people a lot of money on Amps they would've been disappointed in.

[@wal]

Thanks for the suggestion

[@93nyjetsfan]

My first system was almost all JL audio. Best audio decision I ever made was to not buy another JL product ever again… price for performance is bad. Great quality products but in this hobby results mean much more

[@Van1018s]

Couldn’t agree more. Extremely overpriced for what you get on all their products.

[@randyowens3633]

Is there any way you can do it dano on a memphis audio prxa1000.1 I've heard A lot of bashing about itBut I'm never had a problem out of the one I got

[@tommylee9339]

Can you test the Power Acoustic RZR-2500.1D at 1ohm? I've seen it tested at its rated 2ohm load and it met the rating, but I've got one at 1ohm and it rarely goes into protect. I really enjoy seeing what amps put out below the rated ohm load. Keep the tests coming, super informational!
