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.

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.

1000 at 2 ohm is not bad. Would be a decent single 12 inch setup. Thinking back I always saw these amps used in installs that for example, a friend of mine who does not work on cars, went to a shop and just had a single 10 inch system installed with the custom made boxes they sold designed for each model of car to fit in spare tire spaces or where the jack would normally be. 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. I remember the one in my buddies firebird was a 10 inch JL in a sealed custom box that came out to be just under one cu ft stuffed with poly fill.

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.

JL Audio has always been a company that delivers well-thought-out, well-designed and reliable products. And these things shouldn't be cheap. The question is whether it can compete on price with European or Japanese amplifiers. If we talk about real SQ, I will always choose a European or Japanese amplifier for not powerful (60-80 watts per channel) 4-channel amplifier for midranges and tweeters. As for subwoofers or subwoofer monoblocks, JL Audio has succeeded in this. Thank you for your test and review.

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.

Good video Big D

One thing JL Audio always provides is super clean and deep sounding bass, especially when you pair their amplifiers with their subwoofers. I always enjoyed the tonality and accuracy of JL equipment. The numbers on the amp dyno don't really address that (SQ) aspect, but it's very important, and its why they are justified in asking a higher price, imho.

My buddy had the old version 1000.d that he cranked all day long. That thing would get warm and that's it. It powered 2 kicker comp r 12's. Not the most powerful, but you probably won't blow it

A caps tolerance is typically plus or minus 5%. The bigger your cap the bigger your tolerances need to be. By using smaller caps you can tighten your electrical tolerances.

Though i myself do not use any JL audio stuff i can say sometimes the high end priced stuff does last. I have a buddy with a rockford t1500.1 that has been pounding away for sooo many years now without a care in the world.

Hey, Big D. Power acoustic has a powered 8" sub at Walmart. Comes with a bass remote. Would like to see a review of this.

multiple caps in parallel allows for less resistance.....but can cost more. but each situation is unique (obviously) -JL amps are extremely well designed and very high quality.. anyone who bashes on them has no idea what they are talking about (unless its about price! LOL)

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

thats cool never seen a amp that rapidly went in and out of protect

ok big D since this isnt a mi9ckey mouse operation which would you buy D4S or JL A?

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. 👍

Using more small caps help distribute the power more efficiently

Does what they say it does, that carries a lot of weight these days. Never had a JL anything and probably never will, but this is a nice amp. Oddly enough, I like that they don't rate it below 2ohm. I'd rather run a higher ohm load and still get the wattage than to have to run everything at 1 or less to get better numbers. Then again, for the price of this one... I could buy a bigger amp from another brand and just run it at 2. I'll keep banging my D'Amore though since it's already bought and paid for.

Great 👍 video.

Many caps in parallel is lower internal resistance. No point having large cap if it can't discharge fast

Capacitors have internal resistance.. more caps less resistance.. so the power supply can handle short high current power draw..

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

I like JL audio Big D but I've ran some of their amps and they didn't last long. I don't play my music super loud and I even got more power to make sure they were not driven hard but maybe a year to two and stinky bombs. 😅

Thank you for the vids Is there any chance you could Test the JL 10w3v3.4 sub?,thank you

Big D still waiting for the hifonics colossus vi test you promised about 10.5 light years ago

I'm still waiting on that cha ching you promised! Goteem!

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?

Im glad that the Brands like JL and RF are still around showing the world what engineering looks like. Beyond reliability and quality. There is predictability. You can depend that their ratings are pretty solid and makes it easy to choose the correct speakers to pair. Most blown speakers these days occur. Because some Korean, off the shelf amp, with no real regulation was used. Then they set their gains the "Reddit" way and clip the signal. Pop even more subs.

Let me guess, you think steve meade is the best too?

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

7:15 The idea is supposed to lower the Equivalent series resistance of the capacitance. The theory is the smaller caps should discharge much faster.

Good vid, but missing the waterside and sound waves outro... 😔

Does it sound better then a Fosgate? Honestly when i have the budget Fosgate makes a great amp, right now my wallet is on a Skar audio budget but man for $500 i got a box with x2 12s and a RP 1200.1d and it hits smooth low and clear. I notice with Skar tho has to be turned perfectly it's my experience after owning 3 dif Skar amps mechanical clipping you can hear, so feed them propper power and tune them accordingly.

Can you elaborate more on why a bunch of smaller capacitors would be better than a few bigger ones? My guess would be more efficient? Easier to fill up a bunch of smaller than a few bigger? Thanks Big D!

You can pack more of them on a smaller footprint and maybe financially it is more better

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

I would like to see you test a sundown audio SAZ 2000

Well the old slash series seem to be a better deal. 1000/1 did 1000W from 1.5 to 4ohms. Back in the day these amps were absolutely some of the best.

I got mine for 50$ on offer up without cover . It works

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.
