A beast 5ch amp - D4S JP95T distortion measurements

[@TokenTombstone]

Thx for testing and posting the info about this amp. I'm a poor so instead of jp95 I bought a Recoil 1800.5. Right now they are less than $200 on amazon and have a bit more power. So far I'm happy with the Recoil.

[@oceanairbrush]

I bought my jp95 on their black friday sale for $195

[@TokenTombstone]

@@oceanairbrush NICE! The bass knob looks great.

[@oceanairbrush]

@@TokenTombstone first one i ever used. The voltage and temp monitor is awesome.

[@BillLambert]

I also got a Recoil 1800.5 a few months ago, mostly because of prime next-day delivery as my old amp was cooked, and so far I like it just fine. I find it quite funny that my DSP is worth more than the amp, but I clamped that Recoil at 1300w to my two 12s and it barely gets warm. Crazy how affordable these things have become.

[@takuachev8885]

@@oceanairbrushI bought mine from a store in Tampa, well traded because I bought another from their store and they have a no return (got wrong ohm) amp but ended up getting it for my mid/highs, I do notice the hiss from my coaxial speakers but ngl, kinda used to it and also better then old blown out stock speakers😭

[@oceanairbrush]

I have one if these installed in a 14 scion tc with two kicker comp r 12's and 4 6.5" hexicones. The hexicones are 8 ohms each and the 4 channel portion is bridged to them. The clarity and sq us just outstanding and the subs slam.

Morning Raw!

[@AcidDeathRitual]

Not bad, bout what I would expect, maybe better. We'll see how mine sounds next week. Probably sound better if my mirror kit and leds come in at the same time😅 I found out why my 90s T-bird doesn't sound like ass from the factory, they shockingly put a bunch of butyl deadner on the floor pans, so my doors aren't necessarily great, the noise floor was just lower. Shockingly well built car aside from dash plastics.

[@christiandshatto7765]

Excellent video, AGAIN! I used one of these, the newer 95t, and the sub output is what impressed me! I liked it better than the d4s jp8, and jp13. ( As a reference I use the mosconi pro430/410 for highs, mids, and tweeters.) The hiss was noticeable, active on my tweeters. Still a very GOOD Value, and if someone runs this amp passive to their components, I bet the hiss isn't there, depending on the quality of the components. How does the titanium look in person? Ty👍🏼👍🏼

[@RAW-CAt]

I love the titanium colour in general🥰 It's not bland as black, not standing out as the coloured ones and looks better than normal silver.

[@cedoman1]

Ha.. "What a time to be alive"... i like that when companies put messages on their boards like back in the day..

[@Silentroller93]

Awesome man, can you test an MM1004? I’m am curious how it stacks up against your Alpine amp.

[@RAW-CAt]

Unless D4S will send me one for some reason. I really have no use for it myself.

[@BarryWhitfield-dj7xf]

Excellent video as always! In the Honda Jazz project, you put the sub enclosure in the spare wheel well. I have a 2010 Mazda 6 station, and I'm planning to do something similar, only I have two subs. What, in your opinion would be best? Mount the subs next to each other parallel to the rear of of the car and as far back as possible or parallel to the sides of the car, one in front of the other. My thinking is that the latter option would be better because, it may help with cancellations. What's your thoughts on this?

[@RAW-CAt]

I would put them as far back as possible.

[@BarryWhitfield-dj7xf]

I'm guessing that will give and over all lower frequency response?

[@dsk-xx]

Another version of big D old school stereo channel. More D4S stuff to come soon

[@RAW-CAt]

Nah, that's the last of D4S,more Alpine coming soon😉

[@kiklop8362]

Please no..... it is just generic amplifier. You can find better ones used. This is just made as cheap as possible based on asian common designs.

[@curbowbass6124]

@@kiklop8362This is an SQ channel. Those Alpine amps he’s using are EXTREMELY clean, which is why he chooses them. No floor noise, unlike D4S and stupid low THD. Cheers!!!!

[@TrealFOET]

Cant get mad at big d for gettin his money 🤑 Jonathan keeps sendin him amps so its free content 🤷🏾‍♂️

[@anandshah71]

How would u compare this amp to a Sony ES series 5 channel amp and Alpine 5 channel r series amps

[@RAW-CAt]

No idea about the sony es🤷

[@therealjohnymexican]

@RAW-Cat different amps, very similar graphs. Is this because they come out the same build house? Maybe different mosfets or different caps? I’d like your insight. Thanks.

[@RAW-CAt]

Most likely. The output will be limited by the power supply mostly, so with the 810 having 8 channels, the power supply is loaded more than on this one, maybe that's why this does more power🤷 But looks to be the same design and most likely same parts. This is how you offer a lot of power for a competitive price.

[@candyman6828]

Hi, greetings from Italy. I'm curious on how to tune a SQLoud car, the "listen behind the car with doors open style", maybe you can make a video about it?

[@RAW-CAt]

Not really. My system has infinite baffle sub and midbass. They don't work with doors open.

[@jw191]

I think someone should make some 7 channel amps; tweeters, mid-range, mid-bass, woofer. Integrated DSP would be good also. I know Helix have the V8, however that’s no good for the woofer 😢

[@408SPLKINGS]

JP D4S does 7 channel 🔊💨💨💨🫠🤯

[@jw191]

@@408SPLKINGS you’re right …

[@brian6029]

How do you get rid of the hiss in the tweeters? I have a morel amp that does it and drives me crazy! 🧐

[@RAW-CAt]

A have another amp for them. My Alpine v12s are hiss-free😉

[@motorax.service.motociclete]

hi, how do you find the sound of these d4s since you have some installed for some time? warmer like a zapco or genesis etc.or more analitical/surgical like a Helix or class D? For example i've had the Crunch GTX 4800 brand new for a couple of days and had a very pleasant sound and full and bass was full (that's even mentioned on hifi magazine) even tho is kind of budget amp. My helixes are much more analytical and almost i don't like them :)

[@RAW-CAt]

They definitely don't sound warm. More clinical as they are very clean THD wise. Noise is what "kills" them for SQ.

[@motorax.service.motociclete]

@@RAW-CAt thanks would love to see you measure that crunch gtx 4800 it's stuck on my head for about 2 years, maybe will find a dealer who will agree? and maybe will find a dealer to share that awave 12ch dsp for testing ...i keep praying :))

[@eustahijelifetips]

Do you run your amplifier through a dsp or hu? Does it have noise at idle? Bought a class d hifonics baby amplifier, runs good and takes a beating but coupled with daytons noise and alt whine makes me listennto music really loud all the time

[@RAW-CAt]

@@eustahijelifetips in my system HU sends digital signal to the DSP and then to amps. As I mentioned already, this specific amplifier has slight hiss on my tweeters. Not all amps do.

[@motorax.service.motociclete]

@@eustahijelifetips just an Alpine head unit on comercial Ground Zero RCA. I don't have any alternator whine/noise. Hifonics made powerfull amplifiers even before. Quality dropped since they have been bought by chineese company

[@cedoman1]

So what do you think about D4S in general.. quality?.. Worth it?

[@kiklop8362]

Check online forums you will find the answer very fast :)

[@RAW-CAt]

Definitely worth the money. They are NOT SQ amps. Loads of power for midbass and subs. Buy the correct gear for the purpose. Every amp can be blown.. We all know that people buy them after watching Big D amp dynos and abuse them to death...and then complain when a 900W rated amp blows pushing way over 1k just because id dynoes that🤦

[@kiklop8362]

​@@RAW-CAt The problem is that it is the selling strategy of D4S. Show how underrated they are and people thinks that they get some free power with them... I think that I am a bit biased about them :)

[@dsk-xx]

Is that 2 set of supply rails? Or one supply rails with 2 transformers ?

[@RAW-CAt]

I would imagine two rails. The power supplies are just sharing the same input terminals for power.

[@dsk-xx]

@@RAW-CAt the layout of transformer doesn't seem like that

[@kiklop8362]

If it is made correctly and has a good protection ( doubt it ) it should not work when you blow any channel. Also one PSU can have influence on second so this should be tested.

[@RAW-CAt]

That is a fair point about the protection. I would like to test it all channels loaded, however my test setup is not designed for that.. however from my previous tests loading all channels vs only one (same as loading one power supply vs both) will have differences in an order of measurement error.

[@kiklop8362]

@@RAW-CAt Yeah the main impact will be probably in power output if it is done correctly and again..... :)

[@bennyblanco14]

I have a question.you mentioned how the damping factor at 50 isn't bad, but i have amps with damping factors from 300 to 1100 @ 4 ohms . Now, i know damping factors aren't everything, but if I remember correctly. The higher the sample rate, the tighter the bass would be so, does the mean at a damping factor of 50 means that the subwoofer is less controlled?

[@RAW-CAt]

Based on my measurements damping factor has zero influence on the bass. At least anything above 20 or so.

[@666nacirema666]

Im just not interested in this amp whatsoever

[@RAW-CAt]

That's understandable. What are you interested in?

[@666nacirema666]

@@RAW-CAt Would be very cool to see some folks create custom roms for that android head unit youve got. Then have you try them out and note any improvements or make suggestions. Can you get older eclipse amps over there? Would be nice to see those tested more. I have a couple that I love but am not setup to test them like you yet. Decided on an interface after testing several I already own and ended up buying a motu since the price was alright and the performance was better than any that I own other than some older firewire options that are just too large and couldnt easily be used in car if I wanted. Gotta get the resistors and everything else now. Id actually like to see more of the amps from brazil out there tested. Anyone over there have a ganfet amp theyd let you test?
