3300W Battleship? Down4Sound JP33 Monoblock Bass Amplifier Amp Dyno Test [4K]

[@StovallsGarage]

Back in the late 90s early 2000s I would have laughed right in someone's face if they said they had a single 3000wrms amp then showed me something that size. Absolutely crazy how far things have come, 98% efficiency... that's borderline magical.

[@brandonsealey4511]

I remember the surf board sized monster amps people were running back then. It really is incredible.

[@Jamez84]

One of the many downsides of old school Class AB amps the horrific size of the amps, the horrific efficiency, etc. Many guys talk up the SQ of Class AB but less than 1% THD is the same if its a Class AB or Class D amp...

[@catch22frubert]

Yeah, look at the JBL Crown 6k that came out in 2005-2006. That was a huge amplifier. Now, you look at the same power from amps like this and the Taramps Smart 5k. They seem tiny for the power they put out.

[@jimbobdobbs1597]

I was calling people idiots last year when they were posting on a site asking if anyone had a used 4k watt amp for sale. I was going to shows when 10k watts was what the PPI van was sporting and had 3" plexi windshield in an astro (ci 1990- 91) , well i guess it was 2 years ago now. Amazing how far (and cheaper) we have progressed

Down4Sound really hit it out of the park with these and I hope they make a crapload of money off these and demonstrate to the rest of the industry that there is strong demand for high quality modern amps with old school looks.

[@wwlittlejOfficial]

With amp efficiency being what they are these days, I really wanna see more downsized, under-the-seat amps. I don't think people realize how loud a 1000w amp really is. Huge bass is mice but after 1-2k it becomes a game of big-box subs to make more bass. I like a decent 10 with 500w in a decent box, I also like storage space for things like people... and stuff.

Theres plenty of loud subs that have small box requirements. Sealed enosures the smallest. And some 12 subs that are 1k rms use 1.5 cubes per sub thats on a 3 cube box design it for ur specific car and the box will seem even smaller.

[@wwlittlejOfficial]

@@joshholden8561 ur missing the point. U can get PLENTY loud and deep with a smaller sub, 10" and like 500 watts, and that 500w amp can literally be the size of your hand. I wanna see more of those amps being tested. 3k is nice but if u run 3k into anything it's gonna be the size of a house. 500-1000w is damn near over kill in a small car enviro with a nice clean install.

Thanks for the beautiful bean footage brotha, keep em comin!

[@justinmurphy2227]

It's like JP literally listened to all the complaints about other amp's design flaws and fixed them. First thing I noticed was the spacing between each power and speaker connection. Next was the connections themselves....power and signal. Like you said, these are some of the best looking RCA connectors I've ever seen in car audio. The amp's preamp stage and the adjustments are just plentiful, they are useful! I know you said the power reminds you of the Orions but to me, the colors and rounded sides, remind me of U.S. Amps and if they decided to made some badass class D amps. I don't know how they could possible compete with these though. I realllllllllyyyyy want to hear a stereo version, 2 or 4 channel and just do some real world good old music listening for testing!

This deserves a re-visit. The JP-23 in uncertified mode draws 134 amps and puts out 1550 into 2 ohms. The JP33 draws 134 amps and puts out 1960 watts at 4 OHMS. so you get 500 watts with the JP33 wi ththe same draw. My electrical stock pretty much with a 145 amp alternator, the big 3 done and a Optima Red Top battery, so this would be huge for me.

im saying the same thing in my head cause at 2 ohm this amp puts out close to 3500 rms close to the 15 inch wdx 7k DB close enough but not over the rms but seems good to me

I'll take a smart 3k or smart 5k with same power at different ohm loads it will make more power at different ohm but these jp amp are awesome looking Tiffany rca should be on every amp in my opinion taramp needs better control knobs then I have no complaints but power to price u can get what 2 smart 5k amps for the price of 1 JP 33

And taramps makes full power at 12.5 volts these korean boards need huge amounts of power.

Taramps definitely wins as far as price to power output and the fact that it makes basically 6k at 1 ohm and 2 ohms. Some people don't care about the $$ difference though and they want a nice Korean half bridge they can run at .5 ohm. I can understand that.

But I've owned zapcos, phase linears, orion, Phoenix golds, and my favourite Rockford punch 150 from 1990 ish. Just something about these amps that just has a much better experience in sound presentation. Anyhow I subscribed to the xtras channel. Salute big d

[@basscaddy1449]

Love the videos you have done on jp amps!! If your were choosing an amp to run a sundown x15v3 which jp amp would you chose if electrical is not an issue I was going to get a salt 4 or 6 but I kinda like the FL orange jp amp would look nice in my set up

[@pantherplatform]

I haven't watched this channel in awhile. Been too satisfied with my skar amps and subs. My Grand Marquis has developed issues that can only be caused by extreme bass like the window regulators falling apart inside the doors and bulbs frequently burning out from excessive vibration

[@Contact_Info]

How many watts you running

[@msh6865]

We're quickly headed toward something I predicted a few years ago...1000 watt amplifiers the size of a wallet or even a credit card. We're not there yet but, it's coming. Such a great time for those into aftermarket car audio. Lots of power for pennies per watt. Crazy the way things have changed since the late 80's.

[@wal]

I agree sir! Hey you’ll like my upcoming video on WAE…the PPI ProMOS 50! Cool little amp!!

Thanks for posting I got this amp earlier today via this channel, but I got black not grey so you might not get any commission. The last JP amp i got via your vid is still kicking after several years of abuse. This tab was still open. Figured I would let you know.

[@bobit8742]

does that said 85c? i wonder what happen, the other amps d4s used 105c, wonder why this new korean amp use 85c. Not that it'll matter, i am sure it will last the lifetime of whatever car this hook up to, but it nice to have that reassurance. 😄

[@jamesvarner758]

Hey Big D, in your opinion, why aren't we going up on the input voltage to get even more power? Say 24v or 48v?

[@wal]

I believe it’s a huge change the industry isn’t ready for. Just like moving from RCA’s to mini XLR’s

[@bassjasinski]

Like the amp and specs just concerned if the bass knob pairing is secure so someone at a competition doesn’t walk around with one of those knobs in there pocket messing with cars

[@D4S-JAKE]

It’s linked only to the chips it’s by 5.0 so you can’t swap pair unless you disconnect like a by speaker with 5.0. I designed it and its also bluetooth certified

[@kabco99]

It's funny how amp's are going the other way now, we went from joker way overrated amp's to quality way underrated amp's, i seriously think JP d4s should rate them a little closer to there actual power output. People will buy them thinking they are close or around the stated power, and build a system around that, just to possibly have their subs blown out because the amp is WAY more powerful then expected.. Just a thought. Great vid Big D👍

[@wal]

I don't have a way to drop my voltage into the 12's with my setup currently, but I'd tend to bet this amp will do it's rated 3300W in the high 12's and unfortunately many people who buy these won't have sufficient electrical and will see voltage drops to there or lower

[@Jt19702]

@@wal can I run this amp with a single run, or do I need to hook up both power/ground terminals? Will be running @ 4ohm

@@peacefrog57 that’s what I was going to buy an AAK4K or Salt 4, but they have such a large footprint compared to this new JP33 amp. What are you running for electrical? I have a northstar 27F AGM and a mechman 340. Two runs of 0. I just ordered a limitless 12k to prepare for the next upgrade.

Great video brother. I have a d4s 4 channel in my Powerstroke. It’s been a good amp and sounds good as well. Doesn’t get hot either. Once I get a 300 amp alternator my Orion 3000.1 will be powering my phoenix gold titanium elites in my truck. If I was looking for a sub amp I would definitely get a down 4 sound amp.

[@wal]

Awesome 👏

[@curtchase3730]

Dayng! Dat beast has enough juice to jump start a locomotive! That amp is the least expensive part of an install. The support equipment will cost over 3x what the amp is going for.

[@wal]

It’s true and people need to understand the importance of strong electrical

[@kriptic22]

Jesus, that amp pulls in some massive current. 😳

[@wal]

Takes power in to make less power out. That's why efficiency is so important. The higher the efficiency, the more output per input

[@Jt19702]

Awesome content Big D. In order to use this amp 4ohm, the use of both power terminals have to be used?

[@wal]

No, the speaker terminals are in parallel. Use one set or both, doesn't matter

[@Jt19702]

@@wal thanks for your reply D. I was actually referring to the Power inputs. I know I will be limited on the power output of the amp. Just wanted to clarify what possibilities are with this amp.

[@WifeBTR123]

I was totally guessing this was a full bridge amplifier. Very surprised it isn't, based on it's size.

[@wal]

I was told it’s the first all surface mount design Korean Half Bridge. This helps keep it more compact. The heatsink is thick and active cooling works well
