Two things brother, first a question would you take this 4k over the Orion HCCA SPLX3000.1D and 2nd those Kicker quad boxes used their lower end L7's I wonder if the box itself could hold up to 4 of their Q class L7's and would love to see how that performs both in just demoing and on a meter in comparison to the lower classed woofers the box came with! 🤔🤷♂️💪🔊🔊🔊

I just got 1 of the 7k models, and let me tell ya this Surge 7k is 1 of the most beautiful designed amps I've personally ever owned. I haven't installed it yet, but so far, in my opinion, these Surge amps remind me a lot of the Sundown SALT series amps, and again, that's just my opinion. Anyways, another great video, sir. I always enjoy, plus, learn stuff when watching your videos.
10:58 It,s nice that in the pover supply section 105°C capacitors are used but i would like to see 105°C in the amp section too. The little 47µF in between the coils also looks like a standard 85°C type. But that,s "nörgeln" on a high level [using , instead of ' because it,s more efficient on a keyboard with german outlay].
Installed my 7k this weekend. Hungry amp. My cyber 12k lithium with 320 amp alt can't hang with it. My Wolfram 5k never dipped under high 13volts. This 7k dropped to 12.3 volts after slamming for 15 minutes.
I'm about 1:59 into this video and this surge 4k looks damn near identical to my deaf bounce aak 4k. Its only missing the clip button and has a clip light on the amplifier.
@Sacred-Mountain Wolf I have 2 brand new VXF 12's that I'm planning on running but I think I'm going to buy 2 Fi HC 12's for my 7k. But at the moment that 1 VXF is absolutely slamming and in the last 5 years that I've had it this sub had never hit so hard!
I been looking at that 7k for over 6+ months now. But then might as well get the 10k and never need another amp again lol. They're pretty fairly priced amps!
To put those numbers into perspective, the 2nd amp is putting out more than 2X the amount of power a oven will draw and 3X what a central air conditioner will draw.
I garauntee the brand will grow as long as the quality of the products doesn't drop. I honestly think that you're not going to find a better comparable amplifier for the price per watt. Take advantage of the pre-sale opportunities if available. I've always received the products I've pre-ordered from previous orders of Wolfram Audio and Surge Audio. I own the 4k,7k,and just got the 10k . Pretty sure the 10k is a 12k Amp in sheep's clothes. The 7k is an 8k I. Sheep's clothes for sure. I love my Korean sound if you don't know the difference between half bridge Korean and anything else please do yourself a favor and buy a Surge Audio Amp.
I noticed there are several amps on the market now that all seem to have a very similar build and bass knob like the D4S amps. Wouldn’t be surprised if they were made by the same manufacturer.
IMO the best SPL related amps are built by S&I. Several companies use them, JP, Surge, Deaf Bonce and many more. It still boggles my mind a 4kW amp can be in such a small footprint. This would have been a 150x2 amp back in the day (90's)
Very nice units, slick design and color scheme, but looking at the amperage draw I'm hugging the fire extinguisher! Holy molly! Great test, great amps, keep it up.
You'll def need a change in your voltage setup with these. They draw big amperages. But you cannot get power without so its expected. Big 3 recommended.
Thanks for another great review! I noticed that the amps drew less amperage at .67 than they did at 1 ohm yet produced more wattage. Very cool. Still, at around 500 to 700 amp draw when pushing them they will absolutely require some beefy electrical upgrades. That said I agree with you, they are very well made amplifiers.
Don't forget these tests are using test tones, music is much more dynamic unless you listen to rebassed stuff. You still need beefed up electrical but not the 320aH of LTO that I have
@@wal Right on. I've just upgraded my Suburban big 4 to 2/0 gauge in anticipation of upcoming changes to my system. 1/0 would have been fine but I found a killer deal on r larger wire so figured why not 😆
Bid D Wiz thank you for doing these videos. Do you know anyone who fixes the old Fosgate amp or have a direction you can point me to? Thank you. Watching from Houston Texas.
Desert audio specialists are the guys I sent my amps to for fixing. They are the actual old school rockford engineers and rockford fosgate pointed me in their direction.
Do ya'll recommend running the 7K @.5ohm if you have the electrical. I have BrandX 390, Dual 0ga power/ground runs everywhere and dual copper 0ga amp inputs on each pwr/ground terminal on for the amp. Oh and 80ah CES Lithium bank. Will be pushing 2 B2 Audio Rage XL 12's. They are rated @2500rms each.
@@ubeuonly Nope. It was for me. Always played music loud at the house and when driving I normally bumped when on the highwys or empty roads. I didn't need to call attention to everyone around me on a packed street. City driving I had my subs turned off or turned waaay down.
@@edtexas5064 as I said, buy some headphones, you're not putting thousands of watts into an audio system in a car for the people inside the car, be real for a moment. I'm not even ghetto mentality but I've always have systems and every car as I've been in the industry for 45 years, never had over 500 w a real power in any car and my system was always capable of 135 decibels and I'm suffering some hearing loss from occasional high-volume use. Big woofers are ignorant and from the streets and made for playing ghetto ass music, and that's not something to be proud of booming down the street. Attention and nothing more.
I'm so glad you tested these amps . There really put out the power . These an the wolfram's are good choices . Being there are very stable under one ohms load. Definitely having lithium battery banks is a must to have them doing the job, preventing clipping on your expensive subwoffers . Thanks again big D wiz love the channel your doing great things . Can you maybe try testing one those , ( RUTHLESS AMPS).
Im kinda confused. I watched another dyno of this amp by Hi-Fi and the amp did 6619 dynamic at 1ohm. This one only did 5575 dynamic at 1ohm. That's a huge difference. Something doesn't seem right. I don't think they are running that much different power wise to test them are they?
I’ve ran a very similar wolfram at .17 on speakers. As long as you rolled into even test tones it never protected. Only protected if you burped tones at clipping. Pretty typical for high quality Korean. Done it with DB aak and salt series also. .33 on speakers is always fine with these types of amps. Just expect a lot of current draw. Great video 👍🏼👍🏼
Somebody math ain’t mathin’. …… .17 load = my 🍑 Good lawd, What’s next? Negative ohm load? That’s what I wire my omega 40k to bro! -.68 ohm load, Do me and I owe you one style!! When you wire reverse (negative ohm load) it’s like a Tesla when it regenerates during braking!
@@caseytbss yes my math is correct. I currently have 3 db aak 20,000.1 wired at .4. They don’t even get hot. Clamp about 21k an amp on speakers. I’ve spent $15k on electrical. So they stay above 16 volts.
Wolfram was basically twisted sounds same exact board different heatsink. As soon as they swapped to the new model amps they started sucking my old 4500 which was number 67 in production was my favorite amp I’ve owned. Got a aw5000 and couldn’t even get 5k out of it. My 4500 clamped almost 6500
@@Chuck_Sanders As I said on my other post: "I think your confusing rebadging with copying. Its two different things. When I first started looking into all these "rebadged" amps I thought just like you. They seemed identical. It wasn't until I looked deeper and did more research that I realized what I though was rebadging was actually different companies coping the same design. Even when you have similar looking products coming from the same builder. You have to look deeper. Look at the components, count the winds on the transformers, disect the mcpcb. Different amp companies can tell these build houses to make a product to different standards. Use a cheap transformer in this brand and a more expensive one in that brand. This is why you see similar looking amps perform differently, even when they come from the same build house. Different component tolerances, thicker board traces, etc... The average person does not pick up on these nuances. They look at the underside of an amp and see that the basic layout is the same as this other amp and just assume they are identical. Its simply not the case. Even amp repair techs like Barevids will tell you they are not identical. He often will say they are the same, but what he means is they are the same layout and basic design, not that they are literally the same."
@@JasonWW2000 so, I have had 3 comments removed. We work and have worked with S and I out of Korean as well as Zennon. We work with Sound and Power, AF, JLD and more out of China, as well as a few other build houses. About 65% or more are rebadged products. They have different heatsinks...and maybe use metal pots and gains attenuators versus a plastic one, and some use "Tiffany style" rca's where others don't. Again, I have dozens upon dozens of cloned SounDigital amplifiers from a few build houses in China, and one in particular makes about 7 brand names and are 100% identical through and through, component for component...and a few have a Big Brand name on the boards, and they just use a black fabric tape glued over the name. The same goes for S and I amplifiers, and with Zennon. Each company brands and pays the premiums for a custom heatsink and silk screening, or etching. Most of these aren't anything new, and are advertiseded with under rated power ratings, as it helps to sell better. Hell, a CAB22 and the Power Acoustik Vertigo 10k are the same, except the CAB22 cheaped out and used less fets. All other components are the same. That's one example only. Subwoofers/drivers...mids to tweeters are no different, as many are just a rebadged speaker/subwoofer. I have been in audio as a whole for over 3 decades, so none of this is new to me. Rebadging/Me too branding is everywhere. From full bridge to half bridge, to speakers and subs...it's more prevalent than you want to believe.
@@Chuck_Sanders Ah, it is good to have someone here who is familiar with manufacturing. I've worked with certain Chinese manufacturers helping design flashlights. I know it's not the same as amps, but it's very similar as far as companies cloning and copying each other. I think we are pretty much in agreement. Your saying it's not rare based on what your seeing more recently plus you have a broader definitionof the term. I'm saying it's rare based on hundreds of brands over several decades plus a narrow definition. So I think we can both be correct depending on the number of brands involved and how we define "rebranded". I think what we are referring to is a bit murky. I don't consider it an exact item if there are changes other than cosmetic. So different rca, different pots, etc... I consider it a clone and not a rebadge. You consider it a rebadge. That also makes my estimation of rebadges smaller than yours. No big deal, I think we are both right. 😁 It would be cool if you could help me educate audio people that just because two amps have similar board layouts it doesn't mean they are exactly the same. It's such a common problem I see. It should always be on a case by case basis and not just assumed. Sometimes they are exactly the same item (Teampie selling to PBoyz, PowerHogg, EMF, JonesSS, etc...), but most of the time they are not (Audiopipe AP3000 and Taramps HD3000). That's really the point I want to get across. Don't assume it's the same. It might be, but not likely.
I forgot about the 1 question I have about this Surge 7k I just purchased. I'm upgrading from a Skar RP3500.1 and the ANL fuses I've got installed right now are 300A. So my question is do I need to go to a larger fuse or is 300A good to go? Any advice is much appreciated because I've been out of the bass scene for quite some time so I'm basically learning about car audio all over. Thanks any and everyone ahead of time!!
Love the video Big D!!! I think it would be awesome if you also did testing comparing the differences as far as the reactive real world in the car clamping the inputs and outputs of an amp to see the differences idk I think it would be cool 😎! Love this little beast of an amp and love the colors!!!
I don't think that kind of testing would be consistent or relevant. There are too many variables. By doing tests in a consistent manor you can better compare different brands and models.
@JasonWW2000 if he was to charge at 14.8 wired to a set of d2 woofers down to 0.5 ohm it would show us, A what the amp could do real world wattage and current pulled after introducing impedance rise I think that would be a petty awesome relative test.
@@justforlaughs8988 Thats both too specific and not specific enough. The impedance curve of the drivers will be influenced by the type of enclosure, size and tuning frequency they are in and the size of the vehicle. The impedance curve is how the amp makes power. We can already infer what the amp will do at lower impedances. So the test you describe would be useless. How would your test be relevant to a person using a Cmax battery? Not very. Most people running really big amps are using lithium. I guess your asking for these tests because you don't know how to take the info from the bench test and translate it into how it would perform in your specific setup. Thats valid, not everyone can do that. You don't really need specifics, you just want a general understanding of how it would work on real music. The only way to know for sure is to try it yourself. Get your subs and play them in your vehicle, watch the impedance change, measure your current draw, see how low your voltage dips, etc... If your setup only ever dips down to say 2 ohm then you know at max unclipped volume this 4k amp is gonna draw about 275 amps. Can your alternator and battery supply that kind of current? If not, limit the volume so the amp draw is less. It really is that simple. Once you know what the amp does you can put that info into your situation and determine if its going to work for you or not. If you want, you can tell me your setup and I can recommend what amp size you should get.
I saw these amps before I purchased my deaf bonce apocalypse AAK.. I had never heard of them before, but I was intrigued. I didn't see much research on these, so I didn't. Now I regret it.
@@wal yeah, but they cost a bit more, and require a lot more electrical. I had a 320 alt, lithium, two agms, and a supercap and still had voltage drop. Hard. From 14.2 to 11.8.. and then clip city.
Is that subwoofer box an off-the-shelf buy or is that a custom made enclosure? I'm definitely gonna buy the 4000 watt amp and want to run a quad woofer setup in my mk4 jetta.
Amazing Power🤯🤯🤯 Brutal Monsters...but they are looking great, nice an smooth... undercover Qualtity?!?!?! Good job as always man... big thumb up for this vid👍🙋♂️
Very nice. I notice the power output counted up very smoothly. Does this translate to better sound quality than ones that don't do that, or is that not noticeable with bass amps?
Another thing I wanted to comment on Every time a amplifier goes into protection it slowly damages components ?You know how I know? From experience? Blowing up amplifiers with not enough current supply to the amplifiers?
Like he said the reason why the amplifier goes into protection at. 5ohms because there is not a impedance rise? If he was using subwoofers it would be. 8ohms or 1ohm
Hi boss i was wondering if when u do the amp dynos do u have to turn up the gain on the amp or not even have to mess with it o was wondering how that works
The gain on the amp is set to the head unit with 10dB of overlap using the DD-1+. Amp won’t produce more power if gain is higher, it will just reach max power sooner. This may be a good video topic 🧐
Absolutely love this amp! I'd trade my salt 8 for a surge 10k, np. Freaking love their bass knob. Way cooler than the salt knobs. These amps take a damn beating too. Well made!
You would need the surge 10K to compete with the salt 8 and the bass knobs are pretty much the same. They're made in the same factory along with the JP amps and the ruthless audio amps.
@@glennonheinrich8185 really, they're made in the same s&i factory in Korea? They're the same bass knob? Wow! You really seem to know your stuff. Thanks bud. Derp.
Layout looks exactly like my D4S Jp23 I know this is a 4k mono and mine a 2.3k mono. But suspect they’re sourcing from same vendor. Even the boxing was similar bass cable same, bass knob similar. Apparently vendor will customize. Also similar is sound Qubed and even CT sounds.
@@shanecunningham6082 It is a company in Korea. I'm not sure if Glennon is just making assumptions of their origin or if he has actual evidence. Typically companies keep it secret who makes their products.
👋 hello Big D Wiz. I've been enjoying your videos for years. I have a Cadence QRS 1.3000D that I would love to have you do a video on. It's for sale and has a very unique design. I can't seem to find any useful examples of these online, which leads me to believe not many were produced. You're the first tech that came to mind back when I purchased it. If this interests you, please let me know. I really would appreciate a thorough bench test. I have other amps that you don't have videos on that would draw some attention. Thanks, Chris
Man I wish they had amps like this when I was in high school back in the late 90s and early 2000s these amps are so cheap per watt compared to back then

Very nice units, slick design and color scheme, but looking at the amperage draw I'm hugging the fire extinguisher! Holy molly! Great test, great amps, keep it up.
Beastly amps.
Congrats on the Sponsorship. Hopefully you get discount codes to share with viewers.
I love how clean it counts upto and past rated power
You'll def need a change in your voltage setup with these. They draw big amperages. But you cannot get power without so its expected. Big 3 recommended.
Crazy stuff! This test was so intense it caused an earthquake in Turkey.
Thanks for another great review! I noticed that the amps drew less amperage at .67 than they did at 1 ohm yet produced more wattage. Very cool. Still, at around 500 to 700 amp draw when pushing them they will absolutely require some beefy electrical upgrades. That said I agree with you, they are very well made amplifiers.
Don't forget these tests are using test tones, music is much more dynamic unless you listen to rebassed stuff. You still need beefed up electrical but not the 320aH of LTO that I have
@@wal Right on. I've just upgraded my Suburban big 4 to 2/0 gauge in anticipation of upcoming changes to my system. 1/0 would have been fine but I found a killer deal on r larger wire so figured why not 😆
Bid D Wiz thank you for doing these videos. Do you know anyone who fixes the old Fosgate amp or have a direction you can point me to? Thank you. Watching from Houston Texas.
Desert audio specialists are the guys I sent my amps to for fixing. They are the actual old school rockford engineers and rockford fosgate pointed me in their direction.
I love it when BigD drops a new video!
Do ya'll recommend running the 7K @.5ohm if you have the electrical. I have BrandX 390, Dual 0ga power/ground runs everywhere and dual copper 0ga amp inputs on each pwr/ground terminal on for the amp. Oh and 80ah CES Lithium bank. Will be pushing 2 B2 Audio Rage XL 12's. They are rated @2500rms each.
Love the surge audio amps but they need to make a 2000.1
Always enjoy your vids and this one is no exception. How about that amp draw! Going to need a serious alternator and and extra battery or two.
John price should sponsor this channel along with skar, sundown, and kicker.
Im going to try this amp out
Good testing we’re is he 10K amp test we got the 4K and the 7k the 10k will be great Test 👍🏻
Budget Gem tested the 10k. It’s linked in the video description
Man, I miss driving around bumping my old system. Not been able to drive a car since 2017 and I 100% miss being a basshead.
Buy some headphones. Bumping bas in the car is not for you. It's for others...not good for your ears...not the most respected either
@@ubeuonly Nope. It was for me. Always played music loud at the house and when driving I normally bumped when on the highwys or empty roads. I didn't need to call attention to everyone around me on a packed street. City driving I had my subs turned off or turned waaay down.
@@edtexas5064 as I said, buy some headphones, you're not putting thousands of watts into an audio system in a car for the people inside the car, be real for a moment. I'm not even ghetto mentality but I've always have systems and every car as I've been in the industry for 45 years, never had over 500 w a real power in any car and my system was always capable of 135 decibels and I'm suffering some hearing loss from occasional high-volume use. Big woofers are ignorant and from the streets and made for playing ghetto ass music, and that's not something to be proud of booming down the street. Attention and nothing more.
I'm so glad you tested these amps . There really put out the power . These an the wolfram's are good choices . Being there are very stable under one ohms load. Definitely having lithium battery banks is a must to have them doing the job, preventing clipping on your expensive subwoffers . Thanks again big D wiz love the channel your doing great things . Can you maybe try testing one those , ( RUTHLESS AMPS).
Great video Big D. if you gonna hook this amp in your car better have some good alternator and wiring.
Every Leatherman owner knows "Surge is King"!
Oh hell yeah!!! I wanna see the 10 k amp. Was thinking of getting the wolfram aw9k but never in stock
Just wanted to let you know at least one guy is hoping you never quit the Allen keys jokes, knowing it's coming just makes it funnier for me
Im kinda confused. I watched another dyno of this amp by Hi-Fi and the amp did 6619 dynamic at 1ohm. This one only did 5575 dynamic at 1ohm. That's a huge difference. Something doesn't seem right. I don't think they are running that much different power wise to test them are they?
Yeah that’s weird Bass dad just did a video on this same amp and he got about same as big d.
I'm sure it's closer to this number.
That's a badass amp for sure
Really nice bass knob
The heatsink design appears to promote effective convection! Prices seem reasonable too. Good numbers and impressive efficiency. Thumbs up for me!
😬👍
I remember what feels like not long ago that an amp with 4000W may as well been infinity watts.
Great price for this product!!
DJ Fishmaster is Watching and Loves Your Videos Brother
Did not know Colin Buckeye was behind this brand...Great AMPS...
I’ve ran a very similar wolfram at .17 on speakers. As long as you rolled into even test tones it never protected. Only protected if you burped tones at clipping. Pretty typical for high quality Korean. Done it with DB aak and salt series also. .33 on speakers is always fine with these types of amps. Just expect a lot of current draw. Great video 👍🏼👍🏼
2x salt8s strapped at .7 clamping almost 25k... 190ah cmax not even stressing the draw lol
Somebody math ain’t mathin’. ……
.17 load = my 🍑
Good lawd, What’s next? Negative ohm load?
That’s what I wire my omega 40k to bro! -.68 ohm load, Do me and I owe you one style!! When you wire reverse (negative ohm load) it’s like a Tesla when it regenerates during braking!
@@scottouimet2865 2 salt 12’s strapped at .25 clamping 49,500. Popped amps frequently
@@caseytbss yes my math is correct. I currently have 3 db aak 20,000.1 wired at .4. They don’t even get hot. Clamp about 21k an amp on speakers. I’ve spent $15k on electrical. So they stay above 16 volts.
@@scottouimet2865 sounds about right. Very nice 👍🏼
Big D, what's your quad box wired to and do you change the wiring when testing different amps?💯
Double dyno goodness! impressive digits!
Thanks for the test's BigD! 😎👍
Thanks for watching and commenting!
Yo bid d did u have the 4 ohm n 2 ohm test results for the 7k boss.
Wolfram was basically twisted sounds same exact board different heatsink. As soon as they swapped to the new model amps they started sucking my old 4500 which was number 67 in production was my favorite amp I’ve owned. Got a aw5000 and couldn’t even get 5k out of it. My 4500 clamped almost 6500
By same exact board, do you mean based on the same layout?
@@JasonWW2000 they were same boards, and same build house
@@Chuck_Sanders As I said on my other post: "I think your confusing rebadging with copying. Its two different things. When I first started looking into all these "rebadged" amps I thought just like you. They seemed identical. It wasn't until I looked deeper and did more research that I realized what I though was rebadging was actually different companies coping the same design. Even when you have similar looking products coming from the same builder. You have to look deeper. Look at the components, count the winds on the transformers, disect the mcpcb. Different amp companies can tell these build houses to make a product to different standards. Use a cheap transformer in this brand and a more expensive one in that brand. This is why you see similar looking amps perform differently, even when they come from the same build house. Different component tolerances, thicker board traces, etc...
The average person does not pick up on these nuances. They look at the underside of an amp and see that the basic layout is the same as this other amp and just assume they are identical. Its simply not the case. Even amp repair techs like Barevids will tell you they are not identical. He often will say they are the same, but what he means is they are the same layout and basic design, not that they are literally the same."
@@JasonWW2000 so, I have had 3 comments removed. We work and have worked with S and I out of Korean as well as Zennon. We work with Sound and Power, AF, JLD and more out of China, as well as a few other build houses. About 65% or more are rebadged products. They have different heatsinks...and maybe use metal pots and gains attenuators versus a plastic one, and some use "Tiffany style" rca's where others don't. Again, I have dozens upon dozens of cloned SounDigital amplifiers from a few build houses in China, and one in particular makes about 7 brand names and are 100% identical through and through, component for component...and a few have a Big Brand name on the boards, and they just use a black fabric tape glued over the name. The same goes for S and I amplifiers, and with Zennon. Each company brands and pays the premiums for a custom heatsink and silk screening, or etching. Most of these aren't anything new, and are advertiseded with under rated power ratings, as it helps to sell better. Hell, a CAB22 and the Power Acoustik Vertigo 10k are the same, except the CAB22 cheaped out and used less fets. All other components are the same. That's one example only. Subwoofers/drivers...mids to tweeters are no different, as many are just a rebadged speaker/subwoofer. I have been in audio as a whole for over 3 decades, so none of this is new to me. Rebadging/Me too branding is everywhere. From full bridge to half bridge, to speakers and subs...it's more prevalent than you want to believe.
@@Chuck_Sanders Ah, it is good to have someone here who is familiar with manufacturing. I've worked with certain Chinese manufacturers helping design flashlights. I know it's not the same as amps, but it's very similar as far as companies cloning and copying each other. I think we are pretty much in agreement. Your saying it's not rare based on what your seeing more recently plus you have a broader definitionof the term. I'm saying it's rare based on hundreds of brands over several decades plus a narrow definition. So I think we can both be correct depending on the number of brands involved and how we define "rebranded".
I think what we are referring to is a bit murky. I don't consider it an exact item if there are changes other than cosmetic. So different rca, different pots, etc... I consider it a clone and not a rebadge. You consider it a rebadge. That also makes my estimation of rebadges smaller than yours. No big deal, I think we are both right. 😁
It would be cool if you could help me educate audio people that just because two amps have similar board layouts it doesn't mean they are exactly the same. It's such a common problem I see. It should always be on a case by case basis and not just assumed. Sometimes they are exactly the same item (Teampie selling to PBoyz, PowerHogg, EMF, JonesSS, etc...), but most of the time they are not (Audiopipe AP3000 and Taramps HD3000).
That's really the point I want to get across. Don't assume it's the same. It might be, but not likely.
I forgot about the 1 question I have about this Surge 7k I just purchased. I'm upgrading from a Skar RP3500.1 and the ANL fuses I've got installed right now are 300A. So my question is do I need to go to a larger fuse or is 300A good to go? Any advice is much appreciated because I've been out of the bass scene for quite some time so I'm basically learning about car audio all over. Thanks any and everyone ahead of time!!
When calculating efficiency. Why do you accept the value 433A if it was 470A ?
Man do I like me some low ohm load amps! Impressive stuff! There is great engineering put into these. And a quality bass knob ta-boot!
Wow. Now I wonder how long they hold up to a beating. If well, they are a solid up and comer for sure.
Looks like another solid option. Thanks, Big D 🤙
Good content loved ever minute of it
Big t-waves enjoy your videos keep up the good work do some belva thank you
Good looking amps! That gray reminds me of the bmw gray.
Yeah! I think KIA has one like this for the Stinger?
@@wal they sho do
Thanks bigD, killer looking amp. Quick question, have you ever benched any of the old GT series Boston Acoustics amps? The Italian ones
I would love to see those dynod as well. I've owned a few of those.
Have you tested any crunch amplifiers like the crunch pdx 1000.4
Love the video Big D!!! I think it would be awesome if you also did testing comparing the differences as far as the reactive real world in the car clamping the inputs and outputs of an amp to see the differences idk I think it would be cool 😎! Love this little beast of an amp and love the colors!!!
I don't think that kind of testing would be consistent or relevant. There are too many variables. By doing tests in a consistent manor you can better compare different brands and models.
@JasonWW2000 if he was to charge at 14.8 wired to a set of d2 woofers down to 0.5 ohm it would show us, A what the amp could do real world wattage and current pulled after introducing impedance rise I think that would be a petty awesome relative test.
@@justforlaughs8988 Thats both too specific and not specific enough. The impedance curve of the drivers will be influenced by the type of enclosure, size and tuning frequency they are in and the size of the vehicle. The impedance curve is how the amp makes power. We can already infer what the amp will do at lower impedances. So the test you describe would be useless. How would your test be relevant to a person using a Cmax battery? Not very. Most people running really big amps are using lithium. I guess your asking for these tests because you don't know how to take the info from the bench test and translate it into how it would perform in your specific setup. Thats valid, not everyone can do that. You don't really need specifics, you just want a general understanding of how it would work on real music. The only way to know for sure is to try it yourself. Get your subs and play them in your vehicle, watch the impedance change, measure your current draw, see how low your voltage dips, etc... If your setup only ever dips down to say 2 ohm then you know at max unclipped volume this 4k amp is gonna draw about 275 amps. Can your alternator and battery supply that kind of current? If not, limit the volume so the amp draw is less. It really is that simple. Once you know what the amp does you can put that info into your situation and determine if its going to work for you or not.
If you want, you can tell me your setup and I can recommend what amp size you should get.
I saw these amps before I purchased my deaf bonce apocalypse AAK.. I had never heard of them before, but I was intrigued. I didn't see much research on these, so I didn't.
Now I regret it.
The AAK’s are beef as well
@@wal yeah, but they cost a bit more, and require a lot more electrical. I had a 320 alt, lithium, two agms, and a supercap and still had voltage drop. Hard. From 14.2 to 11.8.. and then clip city.
Is that subwoofer box an off-the-shelf buy or is that a custom made enclosure?
I'm definitely gonna buy the 4000 watt amp and want to run a quad woofer setup in my mk4 jetta.
Off the shelf from kicker
@@2008guelo thank you. Yeah I later searched like I should have in the first place. 🍻
How hot were they after the test tho??
Amazing Power🤯🤯🤯
Brutal Monsters...but they are looking great, nice an smooth... undercover Qualtity?!?!?!
Good job as always man... big thumb up for this vid👍🙋♂️
Very nice.
I notice the power output counted up very smoothly. Does this translate to better sound quality than ones that don't do that, or is that not noticeable with bass amps?
You dont have to explain im all in 😂 thumbs up 10 secs in!
Have u ever tested any roadstar rda1011 1>4000 watt max
d4s jp33 and jp43 still king at doing rated power and some
The jp33 is also cheaper. I'm sure getting warranty or service from d4s is much easier than surge. I enjoy my jp33
do you have problem with the bluetooth bass knob?
@@bobit8742my jp33 bluetooth bass knob got disconnected. I had to send it in for repair. Free but inconvenient.
@@Sql253 did they fix the issue? they said they updated and everything was fixed but i am still on the fence
@@bobit8742 i got mines back about a month ago. It supposedly has the new updated version. We will see if it has further issues.
Another thing I wanted to comment on Every time a amplifier goes into protection it slowly damages components ?You know how I know? From experience? Blowing up amplifiers with not enough current supply to the amplifiers?
Very nice and clean looking amps :)
If possible, I’d like to see the Marts Digital 13,500
Like he said the reason why the amplifier goes into protection at. 5ohms because there is not a impedance rise? If he was using subwoofers it would be. 8ohms or 1ohm
Hi boss i was wondering if when u do the amp dynos do u have to turn up the gain on the amp or not even have to mess with it o was wondering how that works
The gain on the amp is set to the head unit with 10dB of overlap using the DD-1+. Amp won’t produce more power if gain is higher, it will just reach max power sooner. This may be a good video topic 🧐
like them amps alot i herd alot time ago there just like the wolframs i wonder
Absolutely love this amp! I'd trade my salt 8 for a surge 10k, np. Freaking love their bass knob. Way cooler than the salt knobs. These amps take a damn beating too. Well made!
You would need the surge 10K to compete with the salt 8 and the bass knobs are pretty much the same. They're made in the same factory along with the JP amps and the ruthless audio amps.
@@glennonheinrich8185 for real, I might just call Korea and have my own amps too lol
@@glennonheinrich8185 really, they're made in the same s&i factory in Korea? They're the same bass knob? Wow! You really seem to know your stuff. Thanks bud. Derp.
@@glennonheinrich8185 Are you making assumptions based on appearance?
How about this Surge Audio PS 7000.1D vs the Synergy WFO 5.1D amp? What do you think Big D?
Layout looks exactly like my D4S Jp23 I know this is a 4k mono and mine a 2.3k mono. But suspect they’re sourcing from same vendor. Even the boxing was similar bass cable same, bass knob similar. Apparently vendor will customize. Also similar is sound Qubed and even CT sounds.
JP33 and up are built in the same factory as the surge amps. Also ruthless audio, salt amps and deaf bonce AAKs all from s&I
@@glennonheinrich8185 at end you state all from s&l. What is s&l.
@@shanecunningham6082 It is a company in Korea. I'm not sure if Glennon is just making assumptions of their origin or if he has actual evidence. Typically companies keep it secret who makes their products.

What's the best way to reach you and possibly drag run a critical mass 4x, lmk and yws I'm aware of the scams
👋 hello Big D Wiz. I've been enjoying your videos for years. I have a Cadence QRS 1.3000D that I would love to have you do a video on. It's for sale and has a very unique design. I can't seem to find any useful examples of these online, which leads me to believe not many were produced.
You're the first tech that came to mind back when I purchased it.
If this interests you, please let me know. I really would appreciate a thorough bench test. I have other amps that you don't have videos on that would draw some attention.
Thanks,
Chris
Can you do a Video about The Emphaser Neo SPL or the Emphaser SPL X4
Thanks for the suggestion
I wonder if GaN based supplies could get that efficiency up to 95% for 2 ohm
The double amp Dyno FTW
Wow I was right about Wolfram.
What
Wolfram is open
Would a jp8 amp and 1 sa12 be a good combo ?
Yes I think so I'm going to run a jp8 on a 1200rms 15 at 1ohm should sound good
