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! 🤔🤷♂️💪🔊🔊🔊
Happy to see you are doing sponsorships, you deserve it with all your hard work you have put into this channel. I am glad to see you are still putting in all the objective/scientific power levels and efficiency testing! You can tell its way overbuilt from the extreme dynamic numbers, I am also glad to see the protection circuit works!
Nice to finally see you getting more recognition for your great, realistic reviews and testing. You’re making it easier for those who are new to car audio to not only understand power ratings but to also pick out the right kind of gear. Good job Big D!
Just a 4k amp flexing it's muscle. The numbers and efficiency are crazy good for this level of an amp. Great video. It's also great to see a different tradition start for Surge as a brand.
@@jimmykugel438 I bought one and just ordered another one. Going on 2 dd audio 9512k esp. Sending them in to be swapped to dual 2 ohm and supercharged.

No need to discuss that any further. 👍
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.
@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!
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.
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.
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.
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 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!
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.
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 😆
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)
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).
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.
@@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.
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].
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.
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.
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.
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👍🙋♂️
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?
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.
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?
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.
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.
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?
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.
Just to clarify, I'm not talking crap on these amps, they're clearly very high quality, the amperage draw on the 7k just shocked me, but you gotta pay to play.
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
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

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.
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.
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👍🙋♂️
Awesome amps! Seen them draw some serious amperage too 😁👍👍 2 tests in one video!?!? Damn we are lucky! Keep em goin dude. Awesome videos👍👍👍
Did not know Colin Buckeye was behind this brand...Great AMPS...
wow Surge take my moneyyyyyyy
🤣👍
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.
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
How hot were they after the test tho??
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.
Wow I was right about Wolfram.
What
Wolfram is open
The double amp Dyno FTW
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?
Wow great looking Amplifiers great dyno testing Sir beautiful gut view 👍 👍 🙏 🙏
It’s a scammer
AWESOME AMPS!
Other than the name, I dig these.
Thanks.
Thanks for watching and commenting!
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?
Very cool amp!!!
great video! i cant wait for a dollar/watt chart to come out from you.
Thanks! I can’t wait for that monthly support check you’re sending ☝️😝
@@wal HAHAHAHAHA, i tried
Big t-waves enjoy your videos keep up the good work do some belva thank you
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.
I’d rated it at 500@4ohms w/
Nobody would buy the damn thing….. 🤷♂️🤣
Wow. Now I wonder how long they hold up to a beating. If well, they are a solid up and comer for sure.
Great video Big D. if you gonna hook this amp in your car better have some good alternator and wiring.
Love the video as always those amp looking kind good
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. 🍻
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?
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.
Just to clarify, I'm not talking crap on these amps, they're clearly very high quality, the amperage draw on the 7k just shocked me, but you gotta pay to play.
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
Awesome sauce ❤
That Kicker Loaded enclosure is Bad Ass...
Yeah boi
Have you tested any crunch amplifiers like the crunch pdx 1000.4
That's some chunky power
Over 4600 rms certified! Now thats exstreamly good for a 4000 rms watt amp!💯
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
How much is that 200 dollar amp selling for
🤷♂️
This amp can make more than 14hp.... Crazy!
Good test results.
Good specs.
I hope the manufacturer can support them
😬👍
If possible, I’d like to see the Marts Digital 13,500
Wow! 2800 4 ohm! Always the 4 ohm is what I'm looking at if Class A AB G GH. If D then 1 to .5 as they escalate power as load does.
