Hhhhhh hi m

I finally figured out why so many people have trouble figuring this all out. I was having issues with parallel and didn't understand how 1 voice coil could run 500 at 4 ohms, but then get a whole other coil with it's own resistance and the sub would stay at 500 but have less resistance. When you do "series" you are linking the coils (4ohm) together, therefore; doubling the resistance because the 500 has to travel through 8 ohms of resistance. Then you look at the amp #'s and it says, 2x250 @ 4ohm 2x250 @ 2ohm 1x500 @ 2ohm , the numbers are not important this is what messes people without knowledge up, they look at amps and try to apply that same logic to subs, plus most people truly do not know what is happening in the amp. What I was doing was, I seen 2x4ohm coils and assumed if they were ran in parallel that the resistance would be 4ohm. What I didn't realize is the amp is only ever going to put out 500 at 4ohms, so if I give it 2 coils, that load will be split(50%) between the two coils. Coil 1 uses 250 at 2ohm and coil 2 uses 250 at 2ohms, and 2 x 2ohm loads in parallel = 2 ohms. It makes so much sense now. I just learned this and can already answer one of the biggest questions out there: Is it better to run series or parallel? When you move into a new place, would you rather do it all yourself and get wore out faster, or use 2 people and use half your potential, therefore; lasting longer. You can run 500 through a 4ohm wire at 100% for 5 years, or you can buy DVC and split that 500 into 250 and only run each coil at 50% 250 @ 2ohms for 10 years; for example. I have not learned much about amps yet and if you actually can use that extra 50% on each coil. If you have 2 coils you have 200%, but in parallel you only use 100% and is why the ohms are 50% lower, but can you use that sub at 200% 1000 at 4ohms, if you can do 500 at 2ohm, why can't I cheat and buy a 1000 @ 4ohm and use both coils to their max. From my understanding, DVC is purely to help the longevity. My thing is, if you have SVC and it can do 500 at 4ohm, then you have DVC and it will have 2 x 500 @4ohms, that is not meant to be 2 subs in 1, it is just 2 coils rated the same so you don't have to use one wearing it out faster, you now have 2 coils at low wattage working together to create the desired wattage. I think.

I see now, the sub's material and construction is only rated for 100% and while you do have 2 subs in 1, 200% if you exceed 100%, you risk ruining your equipment.

My homie "I got my shit hooked up at a shop PROFESSIONALLY" lmaooooo

Oh the TS-D12D4 is definitely a better subwoofer.

Quality Mobile Video Very grateful Sir 🙏

:)

Quality Mobile Video so i have two memphis m6 12s 700 watts rms... so 1400 total. Planning to push them with Audio Control lc 1.1500 . Is that a good match? Or should i go stronger amp?

Persoanlly, I would focus more on what kind of load you want to make first. I purposely have a 2 ohm sub/amp setup. I prefer that because it still offers a lot of power with good efficiency, and I don't need to be the loudest car on the block. Going to 1 ohm gets you a lot more power than 2 ohm so a lot of people prefer that, but your system will be running hot whenever you bump it loud, plus you may need to upgrade power supply deoending on how powerful of a system you put together. From there, I would focus on the subs, favorite brand/style/looks, then an amplifier with the appropriate ratings and impedances to meet your planned system's load - James :)

If you want all your fenders flexing go with 2 15s at 1 ohm lol 😆

Can I get the model of your amp?

Technically you can, but you'll blow your subwoofer.

Sense*.... They're jokes bud. Relax

@@Qualitymobilevideo i get the context. Just saying probably would have more subs if you werent constantly reminding them of how dumb they were lmao

@@JonnyBGood420 i dont mind hes presentation. Stop being a snowflake

U have no sense of humor I subscribe because how he is lol 😂

MY DUDE

How about I show you! This is our video on wiring Two DVC 4 ohm subwoofers to an amplifier: kzfaq.info/get/bejne/nN-peKef25O4Z6M.html

Look up what your amp pushes at a 4ohm load. It's prob 1/4 of the amps total watt. 1ohm =1500 2ohm =900 4ohm=750 watt I'm just guessing. But I bet I'm close. But 750 watts to a 500w rms sub is fantastic. That means you're putting adequate power to the sub. Again I'm just guessing. You can look uo you're exact amp and see what a 4ohm load output in wattage Is.

:D

Glad you think so!

The JVC can only be wired to a 4 ohm load, so you need to find an amplifier with a comparable RMS at 4 ohms. The Kicker cna be wired to 1 ohm or 4 ohm. So same thing, an amplifier with a comparable RMS @ 1 ohm or 4 ohm

No

Don't c y not

@@ak74headshottaa73 thats what I was thinking since the main power and ground are being broke down inside the power amps. seems like you would be able to run a 4ohm set of component speakers for instance off a 4ohm amp and a 2ohm sub off a 2ohm amp....i mean maybe im missing something but that makes sense to me that it would be possible to do that.

That's gonna sound good.

A monoblock amp is a single channel. Your amp may have dual outputs but those are paralleled. If you connect two 2 ohm voice coils in parallel you will have a 1 ohm load.

Are the subs 2 ohm or 4 ohm? DVC or SVC?

Is the amp a monoblock? Or a 2-channel/4-channel?

Yes a 2 channel

@@Qualitymobilevideo ok sooooo i believe i have it, i kept watching rewinding starting over etc.., 2 dvc 500 watt rms paralleled @ 1 ohm to an amp @ 1 ohm stable monoblock class D that has either 2000 rms x1 @ 1 ohm or 1500 rms x1 @ 1 ohm..I'm still trying to decide. You said i am able to go a little over my rms rating by calculating 1k x 1.20 and then 1k x .90 which is the 900 to 1200 range. 1500 is great but would 2k be wonderful?, that is where i am now. Thank you so so soooo much for these videos!! 👍👍😊

@@DABASS-yt2iy Of course glad you found them helpful!

If you want your car blown to Jupiter, yes.

Perfect match @ 1 ohm! Both rated at 1200W RMS

It just makes no sense

@@ericthegeneric1611 Wow, it's been so long since i posed the question that I forgot what I asked. Let me rephrase my question. I have a stereo power amp that only supports down to 4 ohm loads on each channel and can't be bridged. I also have a dual voice coil 4 ohm sub. It appears that I have three options to connect the two together, 1) Use one channel from the amp and only connect one voice coil, 2) bridge the two voice coils on the sub together and still use on channel on the amp to drive it, or 3) connect each voice coil to a channel on the stereo amplifier. Out of the options, it seems that option 3 would best utilize the power capabilities of the stereo amplifier as long as i make sure I keep the positive and negative connects from the power amp correctly oriented, no?

@@midlander3760 is the amp monoblock and what kind of class. A/B or D. You know what, send me the model number of the amp so I can look it up and study it. From there I'll help you better.

@@ericthegeneric1611 The amp is actually an old home stereo receiver that I was going to use to power a passive sub for home use, so that's why I say the receiver can't be bridged. Based on that, I only have the option of using one channel of the receiver or using both channels to each voice coil of a dual-voice coil sub, which would seem to be a better use of the receiver's power. From what I have read elsewhere, that should work just find as long as I hookup the positive and negative terminals to each voice coil correctly so that the two receiver channels don't fight against each other when powering the voice coils.

@@midlander3760 If the sub you have has a 4 ohm impedance and it's a DVC and your stereo amp has a 4 ohm load then you can wire your sub Series which will put your sub on 8 ohms which is more safer for me. But let me study your way of wiring each to its own VC.

That would actually be an interesting test. What specific amplifier do you have? I'm guessing it's a class D? What's the model?

Soundstream TN1.1200D - Older model with the fuses, not the updated without the fuses(those are junk). I've seen it dynoed on Sonic Electronix channel, so I know it will do the power. Sub is a Sundown SD3-10.

Just wanted to add I never bought anything for this car yet. Still searching for the right setup. And I will definitely keep going back to watch your videos again. There's so much useful info there. Thank you for going out of your way to help us idiots. 🤦😁

Yes that would work

OLD AF lolol, 6 ohm woofers come with strings attached. So two DVC 6 ohm woofers wire to 6 ohm load in series/parallel or a 1.5 ohm load in parallel. Go for parallel and get a 1 ohm amplifier. If they're 1000W RMS each (2,000W RMS combined), get an amplifier that has a range of 1800-2400WRMS @ 1 ohm. But remember, the half ohm will cause a decrease in power. So an amp that does 2000w at 1 ohm will do about 1500w at 1.5 ohm.

Correct!

1 ohm…..if subs are 600 RMS each……2 if both subs add up to 600 RMS

It's the reverse what are your coils on your subs rated for?

Nope! Watch this video, we explain why you have two sets of subwoofer wiring terminals on your monoblock. kzfaq.info/get/bejne/nMV4fZpj2NKWmHU.html

@@Qualitymobilevideo Thank you. That helped.

Are they 700 RMS combined or each?

Actually they are 1000 w peak power each sub but i wanna find out whats the rms ? And what amp i can use

Do you know if the amplifier is bridgeable? Do you have a brand and model number?

@@Qualitymobilevideo its Energy audio and model is Climax5000. 4

@@lt716 Are your wiring any other speakers or subs to it? It's definitely bridgeable @ 4 ohms like the spec you gave me

@@lt716 Their website says "One Subwoofer (SVC)" Watch this video to see who to bridge it: kzfaq.info/get/bejne/rN6HhrFnlc-Zlas.html

@@Qualitymobilevideo its definitely only one subwoofer to give oem system that boost only

Are they DVC or SVC?

@@Qualitymobilevideo DVC I believe

That depends on the subwoofer model.

@@Qualitymobilevideo got the kicker fire down. 2 of them gonna hook up a pioneer d9701 so they can each get their 500 rms. What do you think?

After watching some of your videos I think that would be best. You said thin enclosures need more power

@@fatboy1917 Excellent setup! 👌👌

Watch KZfaq, I quit asking questions that no one as answers but, KZfaq will answer and show you any questions about everything!

Depends on the rest of the specs, the information you provided is vague. I need to know the RMS ratings and impedance ratings of both the sub and the amplifiers, as well as whether the sub is a DVC or SVC, 2 ohm or 4 ohm

I appreciate you Rex

yes you can!

@@Qualitymobilevideo thank you

You're gonna need something powerful for two subs that combine for 1800W RMS! I'd recommend wiring to 1 ohm. Here are some suggestions: www.qualitymobilevideo.com/apcle-18001d.html?KZfaq&Video&Match_Subwoofers-Amplifiers www.qualitymobilevideo.com/brx20161d.html?KZfaq&Video&Match_Subwoofers-Amplifiers www.qualitymobilevideo.com/ar1.4500d.html?KZfaq&Video&Match_Subwoofers-Amplifiers

Nope that's ideal! You want headroom on your amplifier.

@@Qualitymobilevideo Also, when I use ohms law to solve for the output voltage to set my gain, I get 28.28V (sqrt(400x2)). Should I divide this voltage by the amps efficiency and set my gain to that voltage or assume 100% efficient and set my amp gain to 28.28?

RMS to RMS at your running impedance.

@@Qualitymobilevideo it runs a svc at 4 ohms. How do you figure out the amps rms at 4 ohms. Is it the general power rating or rms. Or how do you find out the amps rms if it isn't labeled on the product description or isn't just the general power rating. This is super confusing for no reason lmao

Depends on the impedance of the woofer (2 ohm or 4 ohm) and what impedance's the amplifier can be wired to. What is the exact model of the amplifier?

Quality Mobile Video skar 1200.1d the sub is 2 ohms and the amp is 800w rms at 2 ohms

You absolutely can!

No problem 👍

What Sbuwoofer you go with? I got a GM-8701 with 2 TS-SW3002 subwoofers. Thought about getting the 9701 and hooking it up to them?

You'll have no issue using a 4-ohm sub with an amp that is capable of driving a 2-ohm load. You just will get the 4-ohm output of the amp.

You'll want an amplifier with equal or greater RMS power rating

Quality Mobile Video ok thanks 🙏

Wdym about box? Is is your amp or your subs?

No, you cannot mismatch like that without cause several issues
