Most products today (cars included) do not last as long as older models. Most items are throw away and meant to last just past their warranty. Sad but true in my experience. When companies over build a product the warranty usually indicates that. In my case I am lookong for a couple years of usuage. Anything more is a plus in my book. By then things may have gotten better technology wise. I would like the choice to upgrade and not be forced, but you don't ever truely know unless the warranty backs it up.

Great dynamic headroom, indicative of a overbuilt amplifier! As for the caps you would be surprised how good some of those Chinese caps are. The Eton Core which is an extremely high end SQ amplifier with the lowest distortion of any amplifier in the world… It uses Chinese capacitors (Yuscon but it’s Yuscons high end line) so I think that is a good example of the Chinese making quality components. To get Genuine nichicon capacitors, you have to import them from Japan into China for amplifier assembly so it’s not just the cost of the capacitors its the cost of importing them instead of buying domestically inside of China. I would guess it would add a solid 20 bucks if not 40 bucks to the cost of the amplifier

I ordered a jp23 refurbished amp. Removed my ctsounds ct1500.1d amp that has been faithful for 6 months. Slide the jp23v1.5 in its place, checked preamp voltage, im running oversized 1/0 ofc wire, 2 agm xs d3100 batteries. The amp blew a cap on the filter side within 5 minutes of me having the amp. Thankfully the bottom is clear and I took a picture straight out of the box. You could see the cap was leaking when I got it. So I had to send it back the same day I got it. I have sent it in and I am waiting to see what they say. I was told they would replace all the caps. I wondered why they didn't use better caps myself, the filter caps sax 25 volt caps are only .08 cents each. I trust down4sound will take care of me. Just sucks I waited a week for the amp then had to ship it right back to the repair department. I asked if I could pay the extra money for a new amp and was denied. The listing stated 1 year warranty but it only has 30 days. I'm frustrated, but as long as they make it right is all the counts. Customer service has been great to work with, he is polite and patient. However, he can only do what he is allowed to do. It's up to the company to inspect products and step up when at fault.

Better caps? A great video would be to take an amp (this JP amp would be a good candidate) and recap with high-end caps such as Nichicon or something similar. Then re-run the dyno tests and see if power or distortion specs change. There’s some work to do on selecting the correct replacement caps. Once you pull the stock caps it would be good to analyze them out of circuit for basic characteristics such as ESR. Same for the high quality replacements. Then solder in the replacements and run the dyno tests. I’m happy to help where I can (I’m a EE but not a good one, mostly do software these days because $$$) and can support with tools if needed. If you aren’t comfortable with the recap work, a local repair tech can knock it out in minutes for little coin, just bring him/her the board and caps.

The manufacturer covered it because it was defective, but it cost me $70 in shipping fees, and I had to wait 4 weeks to get a new one. F Down4Sound.

As for better caps, they could make it a special/limited edition of 250 or 500 units. I dunno how much better it'd make an amp in this power range but it'd certainly be interesting to do a head-to-head. (D4S might have an arangement with their supplier that doesn't allow this subisturtion or makes it prohibitively costly) I suspect you'd need to do more than just a brute force output power test. Fidelity in, versus Fidelity out, dunno what test equipment that'd require though so perhaps it isn't a practical showdown.

The caps on most big brands are generic like these. For most they will never experience issues with them. Brands like Nichicon, Panasonic, Rubycon, etc. are used by techs and have lifespans of tens of years. You won't find these caps in virtually ANY amp under $2000 due to the added cost of integrating into the manufacturing process.

Although its funny I have old Alpine amps (T757, 1505 etc) with busted open Nichicon caps but the other caps inside are fine, while I have so many different "cheaper" amps that use these special low profile Chinese caps and none have popped their top on me yet

The issue with putting in supposedly better caps is that most people buy amps based on power and price. If someone else sells a more powerful amp for the same price or less then a lot of people are going to buy that amp thinking it is a better value. In part because most people have no idea what quality parts are. Then again, simply because we have an opinion about one brand versus another doesn't mean we're always right. Is Nichicon always better or is that simply the only name of a brand appreciated for quality that you happen to know? Do we have evidence that Yuscon is always worse or that there is a functional and meaningful difference in their caps that could be heard and appreciated in the noisy world of car audio. As enthusiasts we often assume our desire and passions are shared by everyone but that is almost never the case. If an amp lasts ten years regardless of the brand of caps within it then to most what difference does it make if it doesn't allow them more power for their dollar? And if, say, Kenwood is doing it or ROckford and you have to price your amp fifty dollars more because of the caps you use you will not sell many people into car audio on higher quality when known name brands feel that lower cost caps are just fine. Maybe D4S should do like Kenwood or JL and offer this regular line amp and a pro line like the the Excelon or Slash series with better components, better specs and a better warranty.

It wouldn't cost more than $15-20 per amp for quality caps, taking bulk purchase into consideration. Outside of the caps, everything else in the amp is also going to be lowest common denominator. Hence why similar bic lighters don't last.

As consumers we have known Nichicons to be superior caps for decades but I wonder if we need to accept the possibility of other brands approaching existing standards. Is there any data out there that Capxcons are significantly less reliable? We now accept Korean build houses to be trusted so maybe we need trust them in their sourcing for amps in this price range. I’ve had Nichicons in Eclipse amps fail in the past while the Capxcons in my 5 plus year old Skar in daily commute use are still fine.

Seeing as they would be buying the caps in large quantities I couldn’t see it being more than $20 more in cost per amp for Nichicon or Panasonic. I buy capacitors in the hundreds and thousands and restore vintage electronics for a living. Excluding the large main filters I would say it costs me about $80 or so in capacitors to fully recap them. They have at least triple the amount of capacitors that these car amps have, and seeing that they would only be paying the difference in cost of what they’re already paying for these cheap caps I really can’t see it being more than an extra $20. I’ve purchased new electronics only to replace the cheap caps as preventative maintenance. Too many times have I fixed an electronic for a customer that has failed because it’s 5 year old “Xicon” or “Shanghai” cap has died.
