Great info on the dual inputs...I see a weekend project coming my way!!

I would like to see the test done again after the amp has warmed up. Reverting back to single input test then back to dual input test. Appreciate your time takin on this test.

Yea thanks for the test, looks worth it to me to use them, current was down and wattage up so it a more efficient setup at any power level

Awesome video, keep it up this should clear up any misconceptions ppl have about thos

There you go, you just cost me another set of cables!!! Hahahaah every bit helps !!! :-) :-) :-) :-) :-)

Next test will be just like this but using cca wires instead. Lets see if cca wire makes a bigger difference. Subscribe and stay tuned for more great test videos like this.

awesome video!! well done. Id like to know if using a dual input with a nipple output is better than a dual input using 3 set screws and wire as the output makes a difference CONSIDERING a set screw barely makes contact with the dual inputs output "nipple" whereas it digs into bare wire.

Less current pull for more wattage is always a good thing and reduces stress along the entire system, def a plus.

I think it's worth it plus the amp doesn't work as hard and doesn't pull as many amps but has a power output increase so in my opinion dual inputs ftw

How did you run the power wires did you run to separate wires directly from the battery or one wire into a distribution block putting out 2 0 gauge wires from the one wire

nice video and testing. . . how bout comparing single power and ground with no dual input adaptor. . curious to see if adaptor may resist some power. .

This test is accurate. If you're running a legit 4k monoblock you are gonna need extra batteries in back, hence the amplifier will be close by an using 3 to 6 feet power wire to the battery.

2 dual 1 ohm voice coils to 1 ohm on a single speaker wire vs just running each sub on its own speaker wire to the amplifier. Will there be any voltage increase or will it be the same?

I wonder if a stiffing capacitor will aid things with the one power wire making no need of dual wires?

That amp is Dope AF!!!

Great video can you compare copper vs aluminum dual inputs thanks.

Good test and I think their worth it. Makes it more Efficient and more power at same time. Will obviously make the amp run cooler as well.

Little more power yes, It appears the current draw was more efficient allowing the amp to not work as hard. I think that is more significant long term than the few more watts put out.

copper inputs vs aluminum?

Good test. I know this is 3yrs old, but i hope you or some1 else sees this and does a comparison test with single vs double inputs using copper vs aluminium. 😎✌

So if I'm running two amps that's use 150 fuse and I'm running dual amp inputs would the fuse I use for each power wire be 75 amp? And should my main fuse that's close to the battery be 350 amps

How do oversize adapters compare to the dual inputs? Like how does a 1/0 to 4 gauge adapter compare to dual 4 gauge to single 4 gauge?

Realy make a good showing used the single first amps hot when useing the double so even more impressive

I always try to put some adaptor for power purposes especially dual on these along with 8 gauge or higher like 4 gauge for speaker wire.Its louder with them!😨😨😨

So do u think doing dual copper will be a noticeable difference between dual aluminum inputs ???

AWESOME VID BRO.....I GOTTA COPY THIS AND DO ONE

I have mine. Not installed yet because I need more wire to put them to use. Anything to squeeze those 10ths out.

Where do I get the input adapter from? I need one that goes from 8 gauge to 0 gauge

Great video man! What would be another good one to see is Copper dual terminals vs Aluminum dual terminals. Though you would most likely have to have the same style in both so there is no added or reduced weight in both types of terminals to keep it fair.

They are needed and they look pretty sweet. It really depends on the person but if you have a solid amp why cheap out on inputs.

you should do a test using clamping force and surface area in the input

So that was very interesting🤔 but how about taking 1 stepped further and see what the difference is between aluminum dual inputs compared to the almighty copper dual inputs $$$ is it worth the money?...

You got a little more power using dual 1/0 cable .., What can you get from using dual 2/0 cable??

Even thow incredibly made few more hundred were they shine is in effishentcy and reducing heat and electrical load and your amps component help every thing and when all added up one the single most important thing you can do regardless of size or watts system the small things what makes a ahhh & and separates the wowww systems great job Sundown vidio guys lol

Those dual inputs for power are going to the same battery?

thats cool that the amperage lowered with dual inputs. do same test but with copper ones.

Good video

How about quad inputs ???? They make them I’ve seen tripples too

O yea I have dual inputs I trust them for sure to help the power

sadly I cannot find dual amp inputs copper or aluminum that provide 2/0 inputs with a 2/0 output stud. So basically 2/0 to 2/0 preferably in copper. Only found 2/0 to 1/0 but I dont want a reducer, just 2 to 1.

Great video man. Im kinda confused though. At the end with the results, less amperage made more pwer?! Also, on a load of 1500 to 5000rms, 100 rms seems negligible, to me. I wonder how it would perform on smaller amps. Would 500 become 600? Would even a 100rms channel jump to 150? Thanks man

@Rumblebee2655

Fuse rating is to protect the wire itself and your electrical system itself, not the amp... Another 300a fuse on a second run will be fine for you. The recommended number is what they are saying the max draw should be for the amp without popping the fuse. The fuse is recommended incase the wire is somehow grounded out to prevent a 🔥

now try a set of copper dual inputs please!

The difference shows up more with a dynamic load on a hot day outside. So what was simulated here provide small gain, but it's even further realized when other variables like heat and resistance are factors. Daily drivers shouldn't stress. But an extra 100 watts could be the difference between a tie and winning a trophy on show day! Great unbiased video!

Well besides the fact that there probably isnt a wire ferrule in that whole building , the conductivity of aluminum is %60 of the conductivity of copper. And that number drops to about %50 during high heat situations like car shows and long demos which probably wouldnt show up in this type of test. Copper also loses conductivity in high heat situations but at a lower rate.
