A bank of many smaller capacitors tend to be cheaper than a single 10,000µF capacitor. Also, a big cap tends to take up a lot of vertical space, while a bank of smaller caps will take up a lot of horizontal space. So the dimensions of the box, and the space available on the circuit board plays a role here too. Plus, smaller capacitors will charge and discharge faster than a single large one. This improves transient response time - basically, the speed in which current can flow in and out the capacitor to the rest of the unit. The faster this current can flow, the less the signal is distorted when there is a sudden, high current demand, and the sooner the caps can recover after being depleted (or nearly so). This results high frequencies sounding better at high volumes, and bass notes retaining their "punch" at high volumes. But every capacitor has leakage. This is a tiny amount of current lost within the capacitor. No capacitor is perfect. And when we add a bunch together, we add up the leakage. So we use special capacitors with low leakage - but slightly more expensive. And using capacitors rated at double the voltage for their intended use also lowers leakage - again, more expensive. Thus, a 35v application would use a 70v capacitor to minimize leakage. Cheap engineers and/or manufacturers will use caps at or near their rated voltage to save money. Too much leakage, can reduce the voltage available to the unit, reduce efficiency, and reduce the life span of the caps themselves. Also, each cap has a tiny chance of failure at any given time. So a large bank of many small caps increase that chance of failure by the number of caps. Sometimes you will find a small cap in parallel with a large cap. This small cap is called a bypass cap. It's there to handle those fast transients (high notes at high volume) while the big cap handles the bulk of the current demand. it's not as effective as a bunch of small caps, but the failure rate is far less, and it takes up less real estate on the circuit board. You may notice that some boards have all kinds of free real estate, while others are crammed with electronic components.

[@Fk8td]

This absolute explains why my JL hd1200.1 amp has so much more punch than my previous infinity k1000. Both used the same input signal and keeping same settings it sounded so much more punchy.

[@polluxcastor1143]

When you put bunch of them in parallel it also reduces the parasitic resistance aka ESR...

[@godzilla12325]

This kinda knowledge is priceless and was explained very well, even a dumbfuck like me could fillow that 😂 cheers bro 👌

[@robertbox5399]

High voltage caps have a much higher ESR than lower voltage ones so you will more of them. Using caps rated at higher temperature and voltage drastically improves their lifetime (doubles for each 10deg below their rating)

[@billgatesXP]

Wish there was distortion, intermodulation, and also more circuit layout discussion like we get on ASR forums. Parallel caps have lower ESR than usually can be achieved in a single larger can. I think Panasonic doesn’t even make large value snap-in capacitors anymore.

Yes, due to the lower series resistance and inductance. Less power loss and heat dissipation = longer life.

Many smaller caps will have a lower ESR resulting in faster and higher current capabilities. Also, you can distribute the current across more conductor with many smaller caps to distribute (heat) current load across more conductor, resulting in better cooling.

Had 2 of these amps die at the same time in a build. Power supplies both went down virtually simultaneously. Very surprised. No apparent reason why. Was told this is not uncommon under prolonged low voltage conditions- which were seemingly not the issue on this particular build. Not sure if that’s accurate or not. Owner repaired at $400/each and have been fine since. A couple lemons maybe? Nothing against JL. They’re okay. Basically the Apple of the mobile/marine market though. Price to performance ratio is sub par at best.

There is a saying that goes "buy it nice or buy it twice". Furthermore, these are the same people that sate those who buy Ferraris are fools when they can easily buy a corvette for a third of the cost because it does the same thing.... really bro, really... jeez

[@h1nicolas]

The smaller capacitors that are tall rather that wide, this has a better geometry to reduce inductance in the capacitor, ESL (effective series inductance) . As a result they can transfer current better at high frequencies. Since the power supply switches at tens of kilo hertz, this is beneficial since it can deliver power with minimal impedance. The effective ESR (effective series resistance), this has to be low to minimize heat generated in the capacitor, this is stated as you can see on the capacitor "Low ESR", this not always the case.

[@drgenerico83]

Love your videos. This is one where I wish you had done a sub test. It's always good to see.

[@JimP226]

Oddly enough back in the 90s when I was big into this stuff, you were expecting to pay $1 per watt, for real world clean power. At least in Canadian dollars anyway, which at the time was about 35% less than USD. I do like that JL hasn't sold out it's brand and turned it into garbage.

[@tomb9566]

I go back to 1990 JL audio 12 w5's dual 8ohm, and when the w6's triple stack, I had them, and in 99 or 2000 when the w3's came out I was first in line. I have 5 10w0's now. JL's quality has never disappointed.

[@BlackPanther-oo4zj]

Salute! Solid reliable quality amp. You get what you pay for. Buy what you can afford Bassheads.

[@FrankStPeter]

JL is the best😂😂😂😂

[@ZoeyR86]

The smaller caps have a few pros. Reliability, life expectation is higher. Better temp stability. Reduce fire hazard IF one fails. Lower internal inductance for a faster response. Cons Cost more the higher price of a single cap is generally less then the combined cost of 3 or 4 smaller caps plus most caps are installed and soldered by hand so more costs with more assembly. Board trace layout and space. When placing multiple round cans you take up dead space between them. Batch control Generally you want all the caps together to be from the same batch or match esr and inductance so they share the load evenly.

It would always be an alpine head unit, a CD changer, a JL audio amplifier, those custom boxes and a JL audio sub either 10 or 12 inch class.

smaller capacitors with the same total capacitance of a larger cap do not recharge faster or have better thermals. there are caps, big and small that have the same temperature rating. the main advantage to using lots of small caps vs. a few bigger ones would be lower esr (resistance across the cap), handle higher ripple current, and better high frequency rejection.

[@ehrenkrause9861]

@@bensonak47 The only reason I brought up the thermal capacitance wasn't the rating but the volume of mass more mass you have the more he can take at a longer period of time before it degrades.

All things have thermal detegration and usually the slower the Thermo cycles the log or something will last.

Hey WA Lab… I wanted to see if you can either answer or both answer and show amps that have best efficiency. By efficiency, I mean amps that do not tax an car’s electrical system too much, and would/could possibly perform well without huge power output upgrades. Many of the amps you show with decent power take so much amperage to run, that an 100-150amp alternator would barely put out to keep up with most of those 1k amps. And since most newer car’s electrical systems are really sensitive to voltage spikes and drops, that would be a cool series to help people that want to bump & retain an unmolested factory electrics- or mildly upgraded ones that just need a cap or additional battery.

Dunno about this xd line but the HD 1200 is the best I’ve heard. Put up against a taramps 5k and even at same volume or louder the JL is just more detailed. I really tried to make the taramps good enough but it just can reproduce the detail like JL can

[@McTroyd]

Armchair EE nerd here. Electrically, the equivalent series resistance ("ESR") of a capacitor is a big reason why a choice would be made between giant bulk capacitors and an array of smaller ones (as JL has). Just like with the woofers when paralleled, more small capacitors will have a lower ESR, allowing the capacitor array to handle a much bigger peak power draw, as one would see with a thundering subwoofer in a typical music application. There are other considerations as well: -Heat dissipation (more capacitors = more surface area for cooling) -Space usage -Cost of bulk capacitor vs. capacitor array I don't think any of those are a major concern for JL Audio in this application, because: -The enclosed housing and cluster of capacitors wouldn't do much for dissipating heat from the capacitors -They clearly have plenty of space -JL seems to consistently prioritize quality over cost. (I do too.) Thanks for covering, Big D. 👍

[@ROTTBOXX]

Comments are funny 😂. ANY amp can be blown. Jl isn't a Chinese alibaba catalog amp. They have been in the game a long time. And more geared towards the sq crowd or people that just want a little bump. Had the og w6's back in the day. And numerous pairs ov w6 v2's and v3's. Jl will always have my respect.

[@NicoleCil-qo7vy]

Great video!! Can you test the Audiopipe APMOX Amps?? They’re tiny - I can’t believe the power handling 😳

JL is not a cookie cutter brand....JL for the win!

[@josephsaucedo8691]

The RCA not Tiffany and no bass knob ouch for the price no low ohm load for how much 🤯🎶🎵🛠️👌👍✌️

[@smellsuperb1]

Because it's sound quality you're buying, not SPL output. And these amps are tanks when properly powered. Seen plenty running just fine after 12-15 years.

[@josephsaucedo8691]

@smellsuperb1 there other amp that coast less that last just as long when properly used and im positive 90 percent of people aren't going to be able to hear this and say I can tell that it's a JL audio I can hear the sound quality difference . JL good but in my opinion way over priced on a. Lot of there models and most people that are willing to pay way more for some of there models are paying just because of the name like the w7 there cost per sub for the material under 300$ the other 700- 1200$ your pay depending on when and exact model for the name patient and tooling for JL not because the quality that much more. money then any author sub out there again my opinion from what I've seen and if the are so much better you wouldn't see quite a bit of them damage and selling dirt cheap on ebay compared to normal what it originally cost 💯👊👍✌️😉

[@smellsuperb1]

​@@josephsaucedo8691 you're confusing perceived value with actual value. Using FB marketplace as your guide is misleading, bc you're only telling one side of the equation. Also, some people are just selling things out of desperation, they're not concerned about market value. I currently have a car audio store and I've been selling car audio for almost 30 years on and off. JL Audio holds value better than any other US-based brand and I have the sales records to prove it. JL isn't using off-the-shelf motherboards and capacitors, their higher end amps are bespoke. Again, it's not an SPL brand. SQ or SQL, yes definitely. And for every brand that can do similar for a lower price, you have others that can be much more costly (Focal, Audison, Mosconi, Braxton, Morel, etc etc). I'm never going to tell anybody what they should spend, but I will absolutely tell them best overall value for their long-term dollar. And if that happens to be JL for their application I'm going to tell them. You can get better performance from a modern 6-cyl twin turbo Toyota than a 1970 Chevelle SS LS6, but the Chevelle guy isn't wrong for wanting a muscle car.

[@smellsuperb1]

​@@josephsaucedo8691also, 70% of equipment failure is user error/abuse. Don't blame JL for the actions of negligent buyers.

[@WEVA111]

​@@josephsaucedo8691It's comments like this shows me who the brokeys really are Sure you can buy a cheaper amp but the quality is going to be crap forcing one to eventually buy another amp which effectively will make it cost more. There is a saying that goes "buy it nice or buy it twice". Furthermore, these are the same people that sate those who buy Ferraris are fools when they can easily buy a corvette for a third of the cost because it does the same thing.... really bro, really jeez

[@frankgatto9778]

In general 1 per watt is the bar and has been for 20+ years in my book. That's just a very general rule of thumb that's rare to go wrong. That obviously changes the more you understand audio. Love the videos big d! Stay cool

[@alconyers2003]

The bar is 10 cents in 2023. You can’t tell me this amp is better than a CT sounds or D4S.

[@frankgatto9778]

@alconyers2003 no I'm definitely not saying that. That's old technology, depending on how old you are that was the height of technology 20 years ago and was the same price, we didn't have those options. So what I'm saying is that this is something that someone buys that has more money than brains nowadays. Now there's so many options it makes me jealous, I can barely keep up. Now big box brands aren't even on my radar.

[@narmale]

look at the Taramps... 26k RMS power at $3,500.00 not to mention 1/4 of the size of the old stuff... its crazy

[@c31979839]

1$ per watt was always my rule of thumb and expected over the past 30 years or so. But I also remember getting Orions the size of surf boards back then. Amp tech has definitely come a long way, but I do still wonder if the audio quality is the same now as it was back then, or if all people care about nowadays is just pushing the subs, and audio quality comes second.

Multiple capacitors can charge up way faster than a single capacitor. This allows for much faster power response.

I would assume the smaller caps charge and discharge more efficiently. Just a guess.

[@K-Effect]

I’m sure I got this wrong and I’m going to get a bunch of flack for this. Did the engineer who designed the PPI art series amplifiers go from Precision Power to Xtant and then finally to JL? If so then the JL amplifiers at least the ones from around the late 2000 would be the final descendants of the art series lineage?

Hey. I enjoy enjoy your videos and you have become my go to when looking for power on a specific amp. On that note. Is there any chance u could do a test on the DD audio M4? Not m4a or b. But just the last generation m4? I’ve looked all over and haven’t found that on a dyno. I went to that from the sundown salt 4 and it seems significantly more powerful. I ran them both at .5 ohm. Thank you.

[@robertjefferson8275]

Thanks D for another cool video. 😎

[@ranchosdelnorte]

I thought this was going to be an amp from the mid 2000's based on it's size, looks, 2ohm load and regular rca's. I didn't realize it was an amp that was actually currently for sale. It just appears a bit dated and doesn't seem like it has enough features to warrant it's price tag other than implied quality.

JL is one of the last companies from the 2000s trying to cash in on their name.

Thoughts on a used JL 1000/1 like this or the JP23? I have 2 X JL 12W3s and had a JP8. I felt I was maxing the amp and the speakers wanted more than 400 watts each that the JP8 was providing. Ive had XTANT in the past, so Im familiar with quality and damping of the amp. I just want to make sure Im getting loads of easy clean power to the subs.
