WOOOW! I’m super surprised! That has to be the best Precision Power amp built in decades. And I’m not a new school PP fan at all. Korean made, less than a buck a watt and it’s built like a little tank. You can’t beat that. Only time can speak for its reliability but the gut shot speaks volumes about how well it’s built. I’d buy it and that says a lot. I’m not a budget Audio guy at all.
So I ordered one and got it 2 days ago. I got 1200watts at 13.6v 114a making it just about 80% efficiency, NOT BAD AT ALL. Wish it was 90% efficiency so it wouldn’t get so warm (reached 160f after 10 minutes of sine waves).
I'm running a A1000.5D and love it. I was running A1000.4 and A900.1 together then decided to upgrade. I'm seriously considering getting one of these to run my subs while running some transducers on the A1000.5D sub channels. I have them running in a pedicab and they do well in the elements. They are in a unsealed storage area under the seat. Where it gets moisture when it rains.
Sweet!! Its amazing for the price. Next get 1 more strap them together and try .5 ohms strapped that's .25 ohms per amp. I used to have 2 Hifonics amps that were nice and I had them wired to .50 ohms strapped. Now I'm not sure if they can handle half ohms strapped on a constant certified amp dyno but it would make a very nice vid.
Companies are starting figure out over fuse it and sell more amps knowing we will try to guess power from the fuses , I have seen this trend with few others recently .
In the end you get 10w per dollar which is pretty solid. It is the same price and power as Precision Power's SPL30001 but that one is more cheaply made with regular rca's instead of tiffany style and spade type power inputs. I had some hopes for Soundstream's Reserve series(the full sizes ones, not the micro or digital), but now that they've been out a while their reviews seem to be not so hot.
not sure if it will make a difference but the maual shows its ratings are taken at 35hz would you be willing to retest at 35hz to see if it gets closer to rated numbers just for science???
Wish they would rate the amps properly if they rated it as a 1200 watt Korean amp for 128 bucks it will fly off the shelf they don't have to hype it up
They should keep it real and rate it at 600 watts at 1ohm, once people test it and get 1200 they’ll be shocked. More shocked than missing 600watts if you ask me. So 150 at 4, 300 at 2 and 600 at 1 ohm would be perfect numbers for this amp.
6061 aluminum has terrible thermal conductivity. I hope it's EC grade aluminum for thermal performance. It does look like a nice set of power components and layout though.
Thank you! Yea I try to do things more real world since most people’s vehicles are not at 15.5 yo 16v . The power you see from that voltage you will never see in your car unless you have a custom high voltage alternator and lithium setup.
@@HiFiVector all good brotha. Hey I’m so far super inpressed with the 700.4!!! It’s 5db quiter than my jp84. Both amps purchased this week. The jp84 is a powerhouse but a let down since I’m sq oriented and it’s the opposite of that but I took my chance on it wanted to see what all the fuss was about 😏 on the other hand this ppi atom is just a tick louder when idling than my original jl360.4 ab amp that’s been in this rig. My hopes are to find a suitable amp that’s smaller than my jl which is huge and hot but it’s looking like a challenging task in the budget price range ughhh foook man what do we gota do 🤣 I’ll let you know once I get more testing done with the atom I literally just wired it and powered it on havent audio yet since my biggest pet peeve has just been the on power hissing white noise but so far so good from how quiet it’s sounding from all the class ds I’ve tried and this is the 3rd so far. I can send you a gut shot if you give me an email
Why didn't run it up to the 16.8 volts to see if it would make its rated power that way people will know if they run this amp whats needed to get its power
I bought me one, plan on doing just that. Adding fan but I won’t swap out caps. Once I get it I’ll give it a good 4hr stress test to see if any issues arise.
Great videos brother as always. Had a question for you that I needed help with. It's about amplifier power matching to speakers. Why when Dyno testing amps with sine waves we get the rated power usually but when testing music, we get about like Half the rated power. Should we then buy an amplifier that is double the power for the speakers to get the most from them? Eg. Dyno on amp sine wave 1khz 500 rms. Midrange speaker is 500rms continuous. But when playing music, the amp fluctuates around 200 to 250 rms music power. So should I get an amp that is like 1000rms so the music power will be around the 500rms continuous for the speakers ? Thanks for any feedback.
With full range speakers like door speakers it’s not really needed as impedance rise is a lot less than a subwoofer. So with front speakers it’s fine just to match the rating. With a subwoofer impedance rise is a big factor so if you are looking at maximizing your subs performance and give it all the power it is capable of handling usually it is a good idea to go approximately 30 to 40 percent more on amp power. But the amount of impedance or box rise depends on the subwoofer and box design as a whole. Some setups have worse impedance rise than others and some less.
That has the same specs as kicker cxa 1800.1 besides kicker does 1800 rms at 1 and 2 ohm that amp for 3 times the money is 3 times the power and quaility. Ppi should under rated this amps specs instead of bloating to the max.
Stereo imaging does no good on sub frequencies. Stereo imaging below around 100hz functions the same as interference, and the human ear cant distinguish the direction of a sub frequency. Think about why people like bass - it feels like its all around you, no matter where its coming from. In short, panning it just makes one of your ears rumbly and the other not rumbly. Also, trying to stereo image a bass is like putting it out of phase with itself, creating interference patterns that sound awful in most musical contexts.
Recorded in stereo if it's duplicated and each recordings panned hard left and right for wider imaging but I know in 99.99999% of hiphop type songs it's in mono
@@TheGodofSEO You must not be a musician. Sounds like you like to feel the bass and not hear the way it was recorded. Unless all you listen to is hiphop.
@@jimt5683 I ordered and got one, did 1200watts at 1ohm @13.6v and 114 amps. Did sine waves on a resistor and am pretty surprised on it’s price to watts ratio, may not do 1800watts at 1ohm but am more than happy with 1200.
I'm sorry my friend I can't agree with you on this one I think it's a pig wearing lipstick,,, And I don't know which company it was from Korea But they got caught out sourcing to Malaysia,, Kind of like sundown Made in the USA
If you don't know which build house it came from, how can you suggest it was caught being outsourced?? And Sundown isn't made in the U.S.A but some of their subs are ASSEMBLED in the U.S which is totally different
@@jeanious2009 so are DD, Scott at Fi does the same, So does Rusty at DC... MMats, JL and so forth. All of them have subs assembled in the U.S with globally sourced components. It's been that way for decades, as nobody tools baskets, cones, spiders, and we don't mine...press or punch ferrite, and don't machine t- yoke and washers either.

With such limited information in your comment it makes it very difficult to take your word for it. You may be right but without providing any context tge comment is rather irrelevant.
stay away from anything that says max power on it, you want RMS not max power, go with down for sound or taramps or some other brand that doesnt advertise max power, dont feed these fools your money, can get a down for sound for around the same money with as much or more power than this garbage, guess no one cares about a warranty any more

Same old soundstream tarantula numbers for there 2k $128 with Tiffanys, strappable, bass knob is a steal looks nice
Also has balanced differential inputs ….major attraction
Don't let your neg and pos from speaker terminals touch, it doesn't look like it has a protection circuit for that

That's a great value and decent numbers. Beautiful gut shot. Once again, great great video
Looks very similar to JL audio slash boards.😮
Great looking amp thanks for another great video my boi .Keep them coming yeee
Love all the connections being on one side...can't stand the corners/legs. A steal none the less.

I bought this ppi last week hoping it was the correctly rated epsilon variant.
Im just curious, can someone list all the American brands that are now manufactured in Korea?
Have you ever tested the precision power traxx 1500d monoblock I would like to know what it's all about
No I haven’t tested that amp
Request can u do a .5 test i thinking to get 2 strap them and run them at 1ohms
looks like these amps can be stacked up vertically.
I can snag this for 130 atm on Amazon would this pair well with a American Bass xd15 1krms 2kpeak dual 2ohm?
Yea it would be a great addition and sounds great too
Didn't get it rating but very well built and decent parts
Can we talk ya into testing the Atom 4 channel?
I’ll keep that on in mind

Run it at 16 volts 😮
I juat dont understand why PPI just put its real numbers up..they are not bad numbers abd its a beautiful amp
honestly think you should o used dual runs of 1/0 bet you hit those numbers then
Same as rubicon nano- 1/3 power.
