*Dual Amplifier Inputs Tested* *Tech Time Thursday* at Sundown Audio

[@joshhanson6777]

Cca wire vs. Copper wire would be a nice test. We all know copper is better than aluminum but I would like to see the difference on the dyno.

[@UnofficialAudio]

That is on the to do list.

[@hinesvillebass6742]

Diff would he a big ass current draw and not molten hot wire lol

[@jasenlauver4862]

It’s going to be about a 300 to 400 watt difference. The ofc will draw more power.

[@D_WittaK24]

steve meade did this already

[@bkh5746]

Ya know whats funny everyone has problem with cca wire,lol what about the cca voicecoils on subwoofers🤷🏻‍♂️no one ever mentions it.so no matter if ya have cca or ofc ya the main part of the stereo still has cca wire in there.unless ya have copper vc .

[@steltaudio3867]

current drew went down, wattage went up. the test showed me what i needed to know. thanks.

[@michaelvita8]

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

[@Tekjive]

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

[@lowhertzhighspl]

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.

[@rocastyle86]

Try copper duals see if it makes a difference

[@lowhertzhighspl]

copper inputs vs aluminum?

[@deathtocolor8774]

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

[@UnofficialAudio]

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.

[@magicmikebangin15s64]

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.

[@onemantwohands5224]

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

[@hornpub6937]

Why is voltage not tracked here, that's what matters, wattage is the after effect. Good video nonetheless!

[@mikeruizxd5534]

With your damn videos..... I've been slowly moving from my classic mmats moving over to sundown 👍 keep it up

[@shivaramsubhag2362]

Started following you guys, products are amazing, all the way from trinidad

[@robertgriffin1898]

I would love to see if buss bars vs cables on multiple battery setup

[@joshhanson6777]

Great test! Thumbs up for sure. Thanks for putting out videos that you dont have to do.

[@damianhughes5836]

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

[@vincebowling1778]

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

[@extrakimF]

I would like to see this without the dual inputs on the single run tests.

[@easylooker4889]

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.

[@olmosbananas]

how will the amp run cooler if its outputting higher wattage?

[@thecartel6162]

@@olmosbananas If you watch the video you’ll see that it takes less amperage to give out more wattage on Dual inputs vs single inputs.

[@mustang6035]

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.

[@herureset4899]

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.

[@DibeezyTheGifted]

Most definitely

[@johnmeek6790]

Absolutely...amp would last forever running it much more efficiently

[@Rumblebee2655]

I don't know bro, starting voltage was higher in second set of runs, that alone could cause the small differences.

[@RealPivotTV]

@@Rumblebee2655 this was my thought even a .15 increase in voltage would cause more output. I find it strange that he didn’t keep up with the voltage. Most big amps have oversized 1/0 gauge I would argue that a 2/0 gauge would do the same or better than the dual adapters

[@tankdog03ify]

dynamic is where you might see a bigger difference.. because you have more power right there on tap, simulates random bass drops (music) rather than a long draining 40hz tone

[@DaDonBossMan]

tankdog03 the way it was done may be better for trying to achieve spl numbers

[@d77543020]

I guess if you are chasing numbers this will help but to the ear you won't notice

[@efs8552]

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

[@edwardholliman465]

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

[@MARLONMRMUSIC123]

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

[@cartruck1070]

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. 😎✌

[@Cyberslug1]

You should try wire directly into the amp.

[@Rumblebee2655]

I second this

[@Macho09Marian]

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!😨😨😨

[@BillStraub303]

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

[@h2opower]

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

[@Kyle-kr4je]

now try a set of copper dual inputs please!

[@danielmoraes9637]

The efficient increase nice thanks

[@lowhertzhighspl]

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

[@RAMON20IES]

That amp is Dope AF!!!

[@audiofanaticz]

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.

[@herbyverstink]

i seriously doubt there would be a significant difference with a mass of aluminum like that,resistance would be very low.

[@hinesvillebass6742]

Hehe I'd like to see a pure silver terminal best conductor

[@marko9657]

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.

[@darrellw22]

Great info thanks

[@UrAvgBasshead]

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?

[@PMAZMechanic]

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

[@iChubbs_81]

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

[@NVMDSTEvil]

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

[@mykejonesjones1846]

In the 12v -16v world every watt gained helps

[@slimbuick]

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?...

[@AngelGarcia_420]

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. .

[@mr.cosmosaudiojd2993]

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

[@123456littlet]

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

[@carlosreset7501]

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

[@UnofficialAudio]

Efficiency went up that's why more power with less current draw

[@christopheranderson9240]

It would be nice to see how you run your duel inputs from the battery bank

[@UnofficialAudio]

Three runs of each power and ground wire about 48" long come from the battery bank on the floor up to a set of distribution blocks on the table. Then wire about 24-32" long run from the distribution blocks into the amplifier.

[@UnofficialAudio]

And there's an entire video on the channel that shows the test benches, battery banks, power supplies, and I explain everything.

[@christopheranderson9240]

Awesome! I'll do some looking to find the video! Btw... I love my sundown equipment. Running a 1500.1 on 2 SA 12s in a Chrysler 300 backfiring. Took second in state with a high of 146.3 in USACI. Awesome product!!

[@charliefrancis6438]

Dual 1/0 vs single 4/0 would be nice comparison

[@karl6823]

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

[@TheOffPowerZero]

Not for the little more watts more for the current sharing on more wires

[@Tkssa580]

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

[@JayeBass]

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!

[@lowhertzhighspl]

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.

[@นายแสงสุรีย์บรรฑิตชาติ]

Good

[@skyblockjake]

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?

[@lightweightmcdonald]

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

Run it with 20 feet of wire since my my amp is about that far from my battery

[@UnofficialAudio]

Anybody running this amplifier, or one of this size, should have an upgraded electrical system with an extra battery (or two) in the rear of the vehicle. The wire from the rear battery to the amplifier should never be 20ft in length or anywhere close to that. If you're only running like a 1500w amp then you shouldn't ever need dual inputs anyways.

[@gianstevens7918]

@@UnofficialAudio I think Eric has a point, if it makes this kind of a difference on such short runs, it'd make a bigger difference when using longer wires.

[@Latentanimosityduh]

Sundown Audio unofficial Neat. I Never plan on running a single amp over 2k. Was looking at 2k to 2.5k. I apologize for assuming this was an informational video on dual inputs and not the amp.....I only have 3 group34’s under the hood since there is no room in the back and I don’t feel like adding a battery disconnects because I have batteries back there. I also upgraded the factory dual alternators . Sorry I said 20 it is less maybe. Truck is only 20 feet bumper to bumper. And yes the subwoofers and amplifier for it is way in the back by the tailgate under the canopy. I was using your 1/0 300A install kit size which I find just found interesting because I need 2/0 at that length for 300A and I was actually wondering if I should get two kits or just buy 2/0 which I’ll probably still run dual. But thank you for helping me decide.

[@CRXUGLYKID]

I have a question if my aunt takes a 300amp fuse and I decide to run dual inputs Do I add another 300 fuse to the distribution block to run on second line or put a 150 amp fuse in each distribution block line that the dual input us connected to?

[@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 🔥

[@trunkbangking]

Maybe try with 1 run of power and 2 runs of ground.

[@bass-n-truth-inthestix9083]

In this case with this particular amp id say not worth it for a few more watts. Those inputs are 40-80 bucks depending on aluminum or copper

[@PURESOUND4]

I'd pay that price if I were still competing in dB Drag. That power increase can equate to a few more tenths of a dB, which can be the difference between 1st and 2nd place.

For a daily system I don think its worth the price of extra wire and dual inputs just to get 100-200 extra watts that you really want notice. But for the lanes and getting the best score on the meter yes its worth it.

like to see the single wire test done with the wire directly into the amp with wire ferrules

[@Gizmo_-]

seancarraher you won’t see any difference

[@seancarraher]

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.

[@lowhertzhighspl]

moral of the story, they look much better than they perform. aren't as effective as I had assumed they'd be. Only buy if competing and you're needing a few percentage of wattage increase.
