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! 🤔🤷‍♂️💪🔊🔊🔊

Nobody told him, to associate himself with Robert Byrd for all those years, and to have him as his mentor. Nobody told him to say, that black kids could be as smart as white kids. Nobody told him to push crime bills, that were harsher on black Americans.

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.

[@BlenderRookie]

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.

[@chriscarroll3635]

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?

[@Silentroller93]

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.

[@wal]

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)

[@JasonWW2000]

There are many manufacturers and they tend to copy each others designs. So don't assume there is one company just because a product looks similar.

[@barrettalen]

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.

[@tonyfoley9988]

Really nice bass knob

[@stevemaniaci4750]

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).

Love this little beast of an amp and love the colors!!!

[@JasonWW2000]

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.

[@justforlaughs8988]

@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.

[@JasonWW2000]

@@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.

[@ubeuonly]

@@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.

[@TFOTLITBOK_P1_7]

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.

[@wal]

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
