For parallel , 1/Rtotal= (1/R1+R2) + (1/R3 +R4); which is 1/8= 1/16 + 1/16, where the 16 = 8 + 8 in series., simples.

Watch at 1.5 times speed to save time

We are going to re wire the 8 speakers in our bar using this really useful diagram. Thank you x

well this was useful, I got four sets of four totalling 16 and I have had this wrong for six months now! its lucky 8/16 units are a surround sound with seperate amplifiers otherwise I would be having to layer series/paralel curcits under other series/parallel curcits and i would be in hell. I agree with the few people on here say that your explanation needs more clarity but minus this you appear to be right, I also double checked with other places to be sure. anyhow, keep doing what you're doing, and thanks!

Thank you for that Tutorial.Very easy to understand,well spoken not rushed.I understood every word and the directions were simple.I hate when there is to much teck jargin..I would like to know if you can or how you can hook speakers together using diffrent OHM,S

great explanation. Now, could you please tell me how can I add a control volume to each pair? Thanks in advance.

Thank you for the video. I have a 50 watt amp head we have to parallel outputs. I can adjust the ohms from 4, 8, and 16 ohms. I want to connect to cabinets to my amp head. One cabinet is rated at 16 ohms the other at 8 ohms. The 8 ohm has two 300w speakers the 16 ohms two 30watts Therefore, which impedance should I use on my amp head?

great video. can you please help. i have 2 mid range boxes. each with 3x 8ohm speakers in. is there a method to wire these speakers safely. my power amp is 4ohm load. many thanks.

Thanks, that is very helpful and simple. I still have a question.... how to connect 3speakers 8oms instead of 4 ? Is that correct like this: 8oms + 8oms, parallel = 4oms + 8oms (3rd speaker) = 12 ???

Thanks for sharing the impedance matching info. How do I mach the speakers watts to amp watts in the above connection design. Please reply.

Great vid. This helps a lot, but i have a question! What about the wattage?? I have 8 6ohm speakers rated 50W each, what happens with the wattage?? I want to wire all the speakers in my house, and I dont want to kill my stereo.

(for home application) if we use an active subwoofer will it still draw power from the amplifier and still have to formulated first or just plug it in into a pairs of the socket (back L & R maybe) since it already have it own power source??

@bercerobry Let's say you have 10 10 watt speakers and a 100 watt amp. There you would have a matched set of speakers. But lets say you you want to add 10 more, so now you have 20 10 watt speakers. What would happen is because the amp can only give a max of 100 watts it would split the wattage in half. So the speakers would only get 5 watts each. The speakers would still function but you wouldn't get very much sound out of the speaker, and this is obviously a scenario that couldn't be possible unless you had a huge amp or a 70 volt system. Keep in mind the wattage of a speaker is not always what you need to power it. It will run on nominal power.

Do you think I should use a line-level 2nd-room output for use with a separate amplifier & switch on the Onkyo-TX-NR636 for zone 2 so that I can keep the 7.1 sound in the main room so it don't drop down to 5.1 when I use the Powered Zone 2 Speakers (for Patio) and another room at the same time ? Very nice video MclnTEC , Thank you for you're time !!!!

please can you make a video of 12 speakers? i need it.

good day sir I have an 8ohms amplifier and I plan to connect in one channel an 8ohms subwoofer, 8ohms midrange and 8ohms tweeter connected parallel line what is the total ohms will it be thank you for sharing your knowledge with us

as a electronic student i really suffered your explanations lol

can you connect mismatched speakers to an amp? or do the speakers always need to be perfectly equal watts and impedance? And if a speaker does show what it's rating is -is there a way to test the rating of the speaker?

Hi there I like your tutorial thanks for that but I want your advice.I want to install TIC GS3 garden speakers I have around 14 speakers which connection is best for to get good out put and what type of amplifier is good for this Thank you

I understand your explanation, it was very good but I want to put just two 8 ohm speakers on one channel of an 8 ohm amplifier. Please can you tell me how I do that ? Thanks Julie

...cabinet across the back of a 4-door truck & was having trouble getting them all to move together. Some would throw all the way while others wouldn't hardly throw at all. He had two on the far right next to each other, one middle left, 4th far Left end. I simply wired the top coil of far L to top of 2nd right, bottom of far L to bottom of middle. Far R bottom coil to bottom 2nd right, bottom of far R to top of middle, & they all started working & moving in unison together & sounded awesome!!

Hi: I want to connect 14 speaker to 8 ohm power mixer. I need to attached it in series and parallel. How I do it

Awesome Video!!! Also I have a question: What if i have 2 8 ohm speakers whereas the output of the amplifier is also 8 ohms. Shall I converge the speakers in series or are better off in paralell?

Thanks for explain about de amps, but then why the amps burn out (if the input signal and the voltage supply is the correct)? what´s the cause? because one conect speakers with more watts that the amps deliver? as your example 20 10 watt speakers in a 100 watt amp. Thanks for your answer.

Does this work if I connect this to a crossover network before connecting it to an amp?

...reminds me of back in '96 when my friend John needed to drive 3 8ohm woofers with a single stereo 4ohm/channel amp and all 3 were sharing the same enclosure area so they all needed to see the same power. WQe put two in parallel for a 4 ohm load to one channel and the other woofer on the other channel for 1/2 the power out of that channel but an equal amount of power to all 3 woofers! ...then there was the time when another friend needed to drive 4 10" DVC woofers in one long cabinet...

I have 4 passive speakers. 2 subwoofers at 30W/8ohms, 2 mid range speakers at 25W/8ohms, and 4 tweeters at 12W/8ohms. What matching ampllifer should I get for them to work?

Hey dude, I have a denon 2.1 receiver with a left and a right channel with one speaker per channel. Would connecting 2 extra speakers ( 1 extra per Chanel) involve the same thing as you did in the video? And do you have any advise on how to set it up? Thanks

@noobsyb0t Yes you can.

my question how do you hook up 4 /18inchs 8ohms speaker in 2 superate box to one side of your 8ohms amplifier

What if I connect 1 sub to all 4 outputs on a 2 channel amp and the sub was a 4 ohm and the amp did RMS Power at 4 Ohms=125 W x 2 RMS Power at 2 Ohms=190 W x 2 ...what would the impedance be then?

Question... I have a Sony str-dt1080 a/v and recently bought a Paradigm Cinema Trio L/C/R which has 4 mid drivers and 3 tweeters . I don't want to use the bar for all 3 channels. I have loud speakers and want to use this bar as my center. Please give me a word of advice on this. Do I need to go into the par and reconnect to match my impedance?

somebody needs some powerpoint for tutorials. lol. nice video bro. thanks for the info

so how would u connect it, if it was 2.. 8ohms speaker to a 8ohms amps??

hi! on your example 4 speakers in 1 channel. i have a 1, 8ohms channel amp and i want to connect 2, 8 ohms speaker... is it possible? thank you so much!

@123pikk how did I figure this out? The answer is math and research :P if your amp is rated for 8 ohms per channel and you want to connect 2 speakers per channel that are rated 4 ohms, you would connect the 2 speakers in series (like the batteries in a remote, negative to positive |-+-+|) for the left channel and do the same for the right channel. That is assuming that your amp is rated for 8 ohms per channel and the speakers you connect are 4 ohms.

@jabezprayer1 120 volts? Are you sure your not mistaken that for the A/C power? Most amps that have transformer terminals for speakers (in North America) are 70 volts. Apparently there is amps that have 25 volts but I have never come across them. In other countries there are amps that have 100 volts or more.

I have a regular yamaha amp., 8 0hm.. i hook up a single 15",, 4 ohm woofer to each channel, along with 4 tweeters on each woofer.. i have to replace the tweeters every once in a while because they keep burnning out, im thinking maybe my wiring being wrong could be the cause., how would you wire that up?

thanks for the vid, i have my set up this way: 2 sub of 8 ohms in one channel and 2 speakers of 4 ohms in the other channel. so the subs converts to 4 ohms and the speakers converts to 2 ohms, my amp runs much cooler since i reduce the impedance in both channels.

Hi, nice informative vides indeed! Can you tell me how can I connect 14 Speakers (Bose DS 16F loudspeakers) together. How many channels in an AMP will I need to do it? Any suggestions will be appreciated.

I have a qsc 3602 and (4) 4ohm speakers that are 700w rms. How would I connect 8 as in your video example, and how would using 4ohm instead of 8ohm speaker effect the scenario?

Do speaker selectors replace speaker impendence matching?

I am currently running my factory headunit tre an alpine mrv f-240 4 channel amp. i am still using the factory bose 2 ohm speakers, how can i add a center speaker? can i use one positive and a negative from each front channel to create a center channel?

THE OHMS I UNDERSTOOD COULD U TELL ME PLS: THE SPEAKER/S WATTS SHOULDN'T BE MORE THAN AMP/MIXER RIGHT? AS LONG THE SPEAKER/S AREN'T ABOVE THE WATTS AMP IS FINE TO CONNECT RIGHT? ALSO PLS: CAN I CONNECT SPEAKERS SOME ARE PASSIVE SOME ACTIVE AS LONG THE OHMS ARE SAME TO THE AMP AND THE WATTS NOT MORE THAM AMP? ARE ONLY THESE 2 DETAILS WATTS AND OHMS TO PAY ATTENTION TO SO THE SPEAKER/AMP DAMAGE? MANY THANKS I'D REALLY APPRECIATE UR REPLY!

Means I should maintain 4ohm instead of 8ohm right? Thnx buddy!!! More resistance or less resistance should be kept in mind??? Reply plz

Can I connect a 750watt Sub to a 800watt Amp?

I want to connect custom woofer which has more watt than original I am connecting both custom and original together to home theater Will it effect amplifier?? If yes how should I connect two subwoofer of unequal power

Im making a speaker for my FYP. Its a 8 speaker (4left channel 4right channel) with 2 sub woofer(or 1 is enough?) Do i wire it like in the video or should i reduce the amount of speakers. Its mainly for indoor use. thanks

hi, i have ibanez soundwave SW100 that can produce 100w. The original speaker is 8ohms 200watt ( according to the suipplier ). it is possible to add one more 8 ohm speaker in parallel ( it has 2 output jack ). Question : can i change the original speaker to 2 x 400watt RMS ?

how to connect to a 2 channel amp to 3 speakers 1 is heaver whit a bass med and low speakers. and the ather 2 are whit mid and low rang speakers. how to connect those to left and right?

Good Job partner! I'm doing this exact installation today in a fitness center. I'm using a 430 amp with 7 channels and an ohm rating that goes from 4 to 16 ohms. I'm hooking my 8 ohm Yamaha dual cone speakers up in series and then parallel back to the amp. Since with my application I don't need stereo left and right I'm going to use a mono 3.5mm plug to get the same signal (sound up the middle)from my sound source into the amp then out to every speaker. Again, good job, this is very easy to follow for those who've never done this.

If i have three 4ohm speakers on both right and left side and a 4ohm 2-channel amp so how can i connect the three speakers in series? Or is it only possible with four speakers?

sir how about the wattage of each speakers is it for example 4 pcs 400 watts @ 8 ohms speakers to a 400@8ohms amplifiers?

i want to connect 1x 8ohm speaker and 1x 4ohm speaker to a 4ohm amp, what would be the safest connection, series or paralell?

OK. I got one. I want to wire up a little 4ohm sub to a 2 channel amp with 4ohms per channel. I want to run both channels to the sub and wire up a 4ohm speaker to each channel as well but it sounds like shit wired strait that way (pos to pos, neg to neg). What would be the best way to do this?

I have a pair of speakers in 4 different rooms. They are 8 ohms. Can I use the system you described and still use in wall volume controls? I have a Harmon Kardon PM655Vxi amp that says its high voltage, high current. It has High instantaneous current capability and can provide 45 amps of instantaneous current. The amp has a selector to output for 4 ohms and the speakers can be changed to 4 ohms as well.

i have dual 15 in one box 4 omhs .i have two boxes if i connect them parallel that 2 ohms but i also have dual 15s one box at 8 ohms if i connect one 4 ohm and one 8 ohm box parallel will that give me 6 ohms

Actually... it's not divided by 2. Ohm's are added when connected in series, but when it comes to parallel connection there's a formula for this : Speaker1 multipled by Speaker2 and divided by speaker1 plus speaker 2, so it's not just by 2 all the time unless both ohm values are exact the same.

I have a old Yamaha P2100 amp which says on the back 120 volts. I have 10 speakers that have the 70 volt transformer attached to each one. Could I connect 5 per side to this amp?

Hi I got question Can I connect 2 x 100W speakers 6 ohm to my 7 x 50W amplifier with 8ohm impedance?? Thanks

I am looking to connect 6 speakers to a Stereo Receiver. (4 on A and 2 on B). The receiver I am considering is a Sherwood RX5502 100 watt RMS Dual Zone receiver. My speaker options that I am considering are either six speakers that are each 8ohm / 100 watt or 8ohm / 80 watts. Is it possible to safely (with quality results) hook these speakers to this receiver? If so, how do you recommend I hook up the speakers? If not, what would you recommend? Thx, Brian

how would I hook up 4-4 ohm speakers to make 2 ohms?

Can it be used in 4ohm system..and I have one 2 channel amp..can I used 4 Ovel speakers using this diagram..in my 2 channel amp...amp rating 2×60rms 4 speakers 80 rms each.pls help me

I think impedance matching is correlated with maximum power transfer, but I am not sure if this is 100% correct, in RF electronics impedance matching equals with no power loss.

cool real simple and easy to understand

Hello, I need to connect 16 x 8Ohm speakers (100W each) to an 2Ch amplifier (300W/Chanel) What is the best way to do this? Is there any limitation on the power amplifier wattage and speakers wattage like the 100V line distribution?(total power of the speakers should not exceed the amp wattage).

The wire for between the speakers from one to the other ? Are there not two hook up on the back of each speaker? Do you hook the single wire to the positive side or the negative side?

Hello, i want to build 2 speakers 4ohm open baffle and i want to use multiple speakers on each speaker, for example one 12 inch sub, a 8 inch mid-woofer, 2 midrange 4 inch, and 4 ribbon tweeters, i got some power amp enough powerful that can drive them easy but my problem or question are the crossovers, can i use 2 of 3-way crossovers for each speaker?? or is better each speaker to have it's own low pass or high pass crossover?? using 2 3-way crossovers on each speaker is a good idea or i will need second amp to drive each crossover separately ? Thanks in advance, Eddie

Hi McInTEC, I need your suggestion, I wrongly connected the polarity of the cable from my Spendor S3/5R2 speakers to my vintage Sansui stereo amplifier as follows: As wrongly the 2 Negatives of the 2 speakers were connected to the one channel of the amplifier and the 2 Positives of the 2 speakers were connected to the another channel of the amplifier. One speaker was working and another speaker was not working. I was confused and didn't notice about the wrong polarity for about 15 minutes, then I checked the cable connections and detected the wrong thing. I became panic and sweated like anything. After I made the correct connection the two speakers sing as usual. But.. even though the speakers are now working, still I have some fear. By the wrong connection: Would the cross-overs of the speakers become weak? Did I do the great mistake? How will be the life and health of the speakers? May I keep the speakers for long time?. If it would become weak, that would how much? Kindly let me know about in detail. I am much worried about the thing. If I hear from you as: 'Need not be worried and the things are fine' , then I will be jumping with my transplanted knees! I very much love these small beauties. But, now I am sleepless. Thank you, Regards, Suseendran.

hi - av got a 4x12 guitar cabinet -2speakers are 8ohm and the outher two are 16ohm -the cab is a output of 8ohms-can this be re wire for a output of 16ohms ???

i have 13 speaker 50w size '8 w/ macthing transformer. my power-amp is 400w per channel 8ohms. how to connect all this speaker to match my amplifier?

i have 8 speakers 20w rms and sherwod amp 200w,how can i connect speakers to the amp,each speaker connect separately to the amp ??

Hello sir, what will be ohm requirement for this setup?? 8 ohm bass + 8 ohm mid + 8 ohm tweet all connected to 3-way 8 ohm crossover = amp output xxx??? is it 2 ohm or 8 ohm coming out of crossover in to amplifier?

Would I Do 8 - 4 ohm speakers the same way? Would it keep 4 ohms? And would a 2 channel or 4 channel amp work better? They are mid loud speakers. 300 watts each@ 4 ohms.

im using 2 4ohm or 8ohm idk the ohm sticker first said 4 then buried over 8ohm so im using a guitar tube amp sounds better at 8 ohm setting and im using a y connector so it makes any extra speakers like the top of the amp i wired to be 8ohms bcuz its 2 12' celistons the cab below peavy 410 has a crossover in it and tweets idk shit about that so id love to plug in somehow other 8 or 4 ohm side of the 410 should i slave an samp to be safe can it be done without a big pain in nut can i buy a multi meter and know? ill use another head like robbin ford for dirtys

How do i connect my 2 subs and 2 tops to 1 amp ?

what happens with the wattage when you wire 2 50w speakers to 1 50w channel?

can i bridged those 4 speakers in your syteem on 1 amp

Hi sir good day we have 75 speaker 8ohms What type of connection you recommend

hey I NEED HELP I HAVE ALREADY THIS AMPLIFIER: QSC GX3 300 Watt 8 Ohm Power Amplifier AND I WANT TO INSTALL IT IN MY TERRACE WITH in - ceiling speakers and a subwofer THAT I NEED TO BUY. my question is which and how many in ceiling speaker and subwofer and wire should i buy if my terrace is 25 x 30 ???? i appreciate your help!!!

So what wattage is this amp you added all this speakers to?

what does it mean that my head says that at 4 ohm config: 1x4 ohm or 2x8 ohm and at 8 ohm conifg: 1x8 ohm or 2x16 ohm?

I have 4 speakers at 8 on each 250 W at Have amp 4 Ohms 480 W and 2 Ω bridge parallel mono 1300 how would be the best way to connect these 2

Can it be connected a 16 Ohms tweeter (with the filter capacitor) to the 4 Ohms full range driver? What would be any difference in sound? Is it safe for both tweeter and the full range driver? What the method should follow? Kindly explain? Thank you.

will I need to do it

Hello Buddy, I am trying to Connect multiple output to a Single channel PA Amp (Its Mono amp for mics) . Just say I have a large area to cover and I would like to spread the sound around a bit. What would be the plan to connect something like 6 or 10 speakers this way? The Speakers are 6 Ohm. The Amp is can take upto 4 ohms. Would really appreciate a detailed reply. P.s- I thought abut connecting 2x 6ohm speakers in series, Then connect 3 such pairs in parallel. Would the impedance be roughly 4 ohms? And I have 6 speakers?

how about 4 ohm bridged and two 8 ohm unbridged to simple 2 ch amp?

What about the number of speaker in a certain room? A esay way to calculate the watts per square feet? I know is soppost to be db, but is a easy way to calculate this?

Very informative sir thank you

Can u make a video..or/ advise how to connect INTEX IT4850 5.1 MultiMedia Speakers to computer... i am unable to connect..

dear sir my amp 6-16 oms 160 watts and speaker is 6 oms 120 watts, can I connect. reply me

plus i have a home project where i want to run 2 4ohm tower speakers an a 1000w kenwood car audio sub of a 350w 2 channel car amp how can i wire the tower speakers to keep them at 4 ohms. your help would be greatly appreciated

what should i consider if i am using a crossover?

dude, can u show me how to calculate speaker watt and ohm if i'm using 300watt 8ohm powered mixer?...if I wanna use 4 speaker for my mixer, which the best speaker watt n ohm?how to connect correctly to my speaker using my mixer, I meant train connecting or like the drawing on ur piece of paper?

@baler18 first you need to know the impedance your amp has for output.

Hi, I have an amp with 12 x 8oms speakers and 3 sounds controllers to control 3 zones. I want 4 speakers in each zones, each bunch of 4 speakers (2left and 2 right each) hooked up to a controller and the 3 controllers hooked up to the amp. Is it safe to go parallel for each bunch of 4 to the controllers and the 3 controllers in parallel to the amp? Thank you for your help! Remi

Nice! It seems a decentralized system? In centralized system one would have maximum of two speakers....In mixed centralized and decentralized one would have many....The sum of the speakers input (watts) has to match the amplifier output (watts) in PA system?

I want to make all rooms listen to the same media without loosing any stereo or make it mono at any room, Okay ,I have 4 rooms , which have 4 speakers for each room "2 left, 2 right". all of these speakers are in the walls itself (which I made a whole inside the rooms walls and put the speakers inside . Each room have a switch key to loud the speakers, switch down/Up. I have an A/V Receiver 9.2 in the flat beside the door. how to connect them in details please ,

yo mann..i got 2 speakers of 15W and 8Ohms each and i want to connect them.can i modify it for my pc speakers or mobile using the headphone wires?and how much resistance do i need for it?thanks in advance :)

hi, i have a yamaha s7000 amp ,so how many speaker can i connect to with 500wtts speakers
