Thank God. Finally a solution that caters to absolutely everyone....so many videos that offer this then go on to tell you "it only applies if ....."
Great video. Subscribed. The end
..hmmm... the very best way is to direct connect from RCA line out AND main out (RCA Y connectors) on a Vintage Receiver into High Level Inputs on a powered sub woofer. T...I connected a Marantz 2275 to an ENERGY EPS-100 Sub...piece of cake...Must be Y connectors and connected Horizontally L & R and NOT vertically L & R.
@@adirectconflict The 'pre-out RCA' plugs have volume controlled by the Volume knob, and that's what you need to happen; while the 'tape deck record out RCA' plugs have a constant volume level and you want the sub-woofer volume to follow the volume level of the speakers connected to A or B, or both.
The best tutorial on the internet regarding this topic! From the meter to the hookup, VERY well done, thank you!

Waited three years to actually see it, when you have to use the "pre out".
Tnx
An hour later got it all working and sounding beautifully.
Again thanks a mill.

I got this figured out on my own a few years ago. I wish I would have found your channel back then, it took me a while to get it right. What a difference it makes to add a sub to your vintage system. I went from a good stereo sound to what seems for all the world like being at a nightclub. You get that rich floor to your sound that really gives you a live performance feeling. I love it.
Can You help me please
another great video Kevin. I just got a sub. I have it hooked up to the "B" speaker outputs so I can easily switch it in & out to compare the difference in frequency response & set the gain level .....
Originally I was using my vintage receiver minus the sub, but on some songs I could "feel" something lacking in the lower range. Adding a small sub at 50hz has taken care of that.
I'd never had a subwoofer, but I found my new 20 watt valve amp just didn't have enough bass so I bought a second hand Velodyne and I was blown away by how well it worked. Very useful video, thanks.
Very nice!
Thanks for this video - I have run into all of the scenarios you discussed in connecting subwoofers to a variety of vintage (and not-so vintage) home and car equipment. I'm a little embarrassed to say that I never thought to check the load with an ohm meter, as you did, by splicing the wires from the subwoofer and speaker. I really enjoy your low-key and informative style - please keep 'em coming!
Thanks!
@@skylabsaudio great video, cool chill style. I have a question, why is using the high level speaker out better than line level? and why not use the tape deck record out rca outputs instead of going out of the pre amp? would the record out on my technics su8600 be from directly from the pre amp anyway?
@@aaronbridges8098 The 'pre-out RCA' plugs have volume controlled by the Volume knob, and that's what you need to happen; while the 'tape deck record out RCA' plugs have a constant volume level and you want the sub-woofer volume to follow the volume level of the speakers connected to A or B, or both.
@@kylesmithiii6150 ahuh! well that makes perfect sense!
I never thought I would want a sub, but I won one in an auction lot and needed to test it to sell it. Most stuff I don't feel a need for it, but for bass heavy stuff like Funk and Disco, it added an extra oomph for parties I liked. I ended up keeping it. I just connected it to my B speaker jacks. It was great to find out I can just add another pair of speakers to it without a problem.
I bought a little line level converter from my local car audio store. The owner had never heard of using one for adding a sub to a vintage receiver. If you get one like this kicker with the attenuation pots, definitely start from the bottom and work you way up. I found on the one I bought that all the way "up" was full pass through. They ended up about 5% up from 0.
Glad I found your channel. I have been out of the loop for hifi for a long time. Recently got reacquainted with my equipment enjoying listening and following again. Thanks for the info!
I used your solution 1. My bookshelf loudspeakers now sound more balanced being fed the full range output of the receiver. My receiver serves as a power amp for the stereo DAC, so the “point one” of the 5.1 feature of its sub out wouldn’t be missed anyway. As you showed, the hi level inputs of the subwoofer connected with the wire to the speakers worked perfectly. Thanks.
New to getting into the vintage hifi game and really appreciate this video! Will make connecting a sub to my Pioneer receiver a breeze.
A lot of newer subs don't have the speaker level input. I use a similar adaptor in my system. It sounds better using the speaker out to an adaptor than a sub out. Even when using modern gear.
Yes - I've actually used #3 - it's not super sleek, but it does work! Good job!
I just learned how to do scenario #2 on Sunday by a young election. As always, I greatly appreciate you hardwork.
Thx man.. Good stuff.. Nice to see a demo of what was tumbling in my mind
I always asumed that the sub would have a crossover on the high level speaker outs. Very interesting. I love the sound of my AR18s and have long been thinking a sub might be a worthwhile addition.
Enjoyed those concise explanations.
Looks like all these connections will work, nice. The drawback might be that the sub crossover is not limiting the bass to the little main speakers? Thanks for the vid.
Very informative video and worked like a charm. I just hooked up the Kicker converter to my Onkyo TX 1500 and my humble 2.1 system sounds incredible. Been watching your videos for quite some time. Thanks for the entertainment and the knowledge.
It’s an awesome video and it was incredibly well-explained. It completely cleared up all my doubts. 🎥✨
I just wanted to thank you for sharing. Your recommendation was spot on! 🤗
Hi Kevin,
Thanks for making this video, After watching I stopped using the preouts on my Marantz 2275 to my 2 Infinity BU-1's & used the High level inputs instead & used the High Level outputs of the subs to my Shure SR112W's, What a audible improvement! I thought the RCA inputs were the better method to use instead of the High levels, The y adapter on the main in & pre outs was also very enlightening, Love your videos and straight forward presentation style, Nice thumbs
Awesome, thanks so much for this video! Was about to give up on a sub I picked up for my garage. Pioneer SX-1300 receiver with Sony bookshelfs and wanted more bottom end. Never thought of wiring the speakers and the sub together like that, works perfectly. Cheers!
Oh! Thank you for telling us about the attenuation pots. I might go this route.
I suggestion in addition to this that I often have employed with vintage receivers in the past. is I don't know about a lot of other people but I have tended to listen to a lot of my music at a particular volume without really deviating too much from that volume. so what I've done in the past is use one of the tape outs or the tape out on any particular receiver and plug that directly into a subwoofer. now of course one of the problems with doing that is as you increase or decrease the volume the subwoofer won't scale with the volume of the amplifier but in my specific case where I don't really change the volume a whole lot the volume control on the subwoofer itself is all I needed.
I just took a line from my headphone socket out to RCA in on the sub. I’m sure that’s probably not right, but it works, and has for the last few years without issue😬😉
Thank you so much! My rig (Pioneer SX-650) sounds awesome with my subwoofer. Excellent vid and easy to follow. This video answered my questions!
An excellent bottom-dollar option: A pair of the original series of Boston Acoustics A40 (as seen in the bookshelf speakers video) going through a passive Realistic Optimus Pro SW-12 subwoofer. Replace the surrounds as needed, of course. I ran this combination for years with an NAD 3120 integrated amp, and had no need for the loudness button.
Your recommendations are spot on!
Wish this was common knowledge 20 years ago when I got into a PI$$ING match at the high end sales store where I was shopping for a 12" Sub with 'High Level' speaker inputs for my Kenwood Model 11. My Kenwood Model 11 was sold in the US Military Audio/Photo shops in Germany so it does not have Serise I, II or III but is 80 watts. Maybe not the best THD but works well for me. Been recap'ed 15 years ago.
I knew the Sub's High Level Inputs were well over 60 ohms and basically a ghost to the receiver. But the Model 11 also has a switch to separate the Pre-Amp from the Amp but I wanted to do the High Level. The sales man kept trying to upsell me a new 2.1 amp with a sub output. He and his store did not get the sale. The store is now long gone.
You sghould probably use method two , which will free up your amplifier to only play your satellites.
Hi Kevin
Thanks to your clear and concise explanation I have just used method one to connect a 10" powered sub to a Dual CV31 integrated amplifier from 1973.
Amp at 10 watts/channel, sub at 150 watts all at 8 ohms.
I did the easy thing of high pass out to speakers back.
It worked beautifully and sounded great even spinning my licorice on an AT Sound Burger.
Thank you for the new skill and the extra fun it will bring.

My brother used to be able to push his curvy thumb back and touch his forearm.👍
I have done version 1 with my little Class D Nobsound bluetooth receiver. People can't believe how much sound comes out of my little tiny setup in my kitchen, with a hidden sub.
Thanks for the info 👍 you guys will be my goto for any repairs i cant handle myself
Outrageously informative. I’m great full for this info. Just picked up a bunch of older Pioneer material with a Boze subwoofer, now, I know how to deal with it. Saved the flick though.
The 8 ohms is IMPEDANCE, i.e. tit is an active or dynamic property, not just a resistive property. I'm glad this works, you helped me out, but you technically can't measure the impedance with just an ohm meter designed to measure resistance, exclusively.
This is a great subscription. Down to earth, practical and very honest - thank you !!! Can you do a video on how to connect a Blue-Tooth to a vintage receiver. Thanks again . . .
Thank you, Thomas. will do!
I simply connected my sub to my Marantz secondary speaker output and set it at 50hz. Works just fine.
Thank you for all that you do for us that do not know. Could you do a deep dive into speaker cables and the different connectors?
Out to the sub and back to the amp effectively makes the sub wiring a sonic filter. If you avoid it in the chain, it is one less component to filter and / or add electronically induced noise. I run dual subs. R / L subs via a Y output per pre out to a Y and run each sub in mono off off a single output channel. Powered subs add miniscule load to the system because they are self powered.
Hey bro thank you so much, this is exactly my situation right now. I'm gonna connect my 18" Sub to my home stereo receiver that has no sub output connection. Thanks for your insightful video and I love the way you patiently explain it all and don't rush through it. Kudos my brother. Take care stay up and stay Blessed †
Thank you very much for this episode and all you offer
I used first scenario. I have a Polk powered subwoofer, run speaker wires to the sub, and from the sub to the speakers. Sub has a built in crossover. Runs fine on my SX-450 and Polk bookshelf speakers.
Fantastic video ! I’m very new to this hobby and set my sub up today using the high level inputs. 🎉 I’m in love with it already
those type of thumbs are perfect for hitch hiking
Nice, you showed all the ways.😊
I’m really enjoying your channel, keep it up ! Because of you I just acquired a vintage Toshiba SA-7100 monster receiver to pair with my recently acquired Thorens Td-160. I brought my Sansui SP-X8000’s out of the mothballs. We’ll see how it goes. Thanks
Appreciate that. Enjoy! Sounds like a fun system :)
This is great information !! Thank's... almost blown my Marantz 2225. Love the knowledge.
Very Helpful video, Thanks 👍
I have used passive Subs for years love the them as long as the crossover in the sub is of good quality and can produce either 120hz - 30hz or 80hz-20hz My DBX 15" bottom firing sub woofer shakes the walls with my my baby Advent II's. powered subs would be my next upgrade.
Great explanation of the options. Thank you.
I have an old jvc ax-44 2ch stereo and have been using a sub with a pac sni-35 LOC. Been working great. Gonna try the y splitter way to see if I can hear a difference.
This video is so helpful! Thank you!!
Questions-
if I have two subwoofers do I send left and right audio to both or one give one sub left one sub right like speakers?
Wonderful video. What if you're working with 4 ohm speakers and want to use the speaker inputs and outputs on the sub?
Thanks you for this one!! My two channel receiver doesn’t have a sub-out and I want to add one. This has been very helpful!
Rock on!! 🤘
ok kev i bought one thanks for the video my klipsch only has 2 rca inputs no outs hope this will work
hi I am using the Pioneer a-10k 2x50w receiver, and decided after years to add a subwoofer, an active yamaha sw-p201 I got, and connected it to the B level, having my passive speakers on A. With a little gain the amplifier started to shut itself off, for some reason, found this video and gonna try to rewire it as per 1st scenario, keeping it all in As, wish me luck :)
Yeah Man it is turning out that most people can detect the Ring Of Truth (or it's absence) pretty well.
That is why I like this video "been there done that - I highly recommend you do it this way and don't do it that other way". I'd lay money that your simple way of laying out the probably best methods while also mentioning the less good ideas - has probably saved several vintage amps from being hurt.
I been using method 3 for a while now works great.
Curious, could you hook up 2 sets of speakers and 2 subs off the A & B speaker outputs? In order to have a set of speakers and a sub in two different rooms running off the one receiver.
Great simple easy to understand video!
Is the kicker adapter not "optimal" for lag reasons? All great solutions. Thanks.
Great content! This info isn’t found many other places and is very valuable. Because I like your content, may I recommend one small observation. Your videos would be even better if you edited them down just a little more. For example, from 2:36 to 2:44, that info is not needed and doesn’t add anything. Also, on method two, around 11:00, you mention Y cables are not recommended if your sub has both signal input and outputs, but you already mentioned that earlier so saying it again is not needed. Keep the great content coming!
I think I might have a possible 4th scenario. My slightly over 20 year old integrated amp has a "Pre-Out 2" with its own volume control. I'm considering adding a sub-woofer and thinking that would be the best connection option (it doesn't have a sub out). Apologies if you covered that option. 😊
For the converter, I have used a Russound ADP 1.2, these are made for home Hifi, not car audio, so no extra wires! Just thought I'd share that. Russound calls it a speaker level to line level interface. Love the channel, keep the info vids coming!! (Also works for using an old, small reciever with no pre-out to connect to an amplifier via RCA or "line level").
Any thoughts on the Pioneer HPM 100's? Looking at a set, never heard them, good, bad?? Please share! Cheers!
I gotta say,u do an awesome job of exsplaing.🤘
I have two different make of subwoofers. Can I hook up the speaker out of one sub woofer to the second sub woofer instead of going to the speakers?
Question on your very first solution: If you split the speaker out on your vintage amplifier so the signal goes both to your speakers as well as to your subwoofer then how do you make sure that the full frequency spectrum coming out of your amplifier gets split between these two speaker types? Isn't this solution muddying your output as the regular speakers will reveal the lower frequencies as well?
very informative, thanks again
Great information. Thank you!
Have a Kenwood kr 6160 1970 receiver. Supports 3 pairs of speakers, only use one pair. But this receiver has a RCA mono jack that supports a center speaker or sub out. This jack output is located on the rear panel next to the speakers terminals. One RCA cable to my pioneer active sub works. Output on the mono jack is always present. Nice surprise on this receiver.
First, great video! I’ve always done the 1st option with main speakers in A and sub in B. As you mentioned, it’s nice to turn the sub off if you want via turning off B. But also, I have high quality speaker wire that’s thick with banana plugs at the ends, making it hard to put both into A like you were with basic speaker wire. Even with a banana plug adapter, for older receivers that aren’t set up for banana plugs (like the Pioneer in this video) it would be hard to connect the speakers and sub to A
👍🏻😎Both of my systems have amplifiers that don't cut power when both the A and B channels are selected and neither one is new enough to have subwoofer outputs. I run a pair of speakers on each channel (a pair on A and a pair on B) and a dedicated subwoofer hooked up speaker level on each channel for a total of 2 subwoofers. I think that configuration sounds the best to my ears. I had a friend tell me a long time ago that I was stupid for running it that way (speaker level Vs. low level) without hearing it first. Needless to say he doesn't come around anymore and I don't ever hear from him anymore either so it must have been a complete shock to him just how good it sounds that way. He thought the only way to hook them up was low level. I think that even if I had an amp with subwoofer outputs I would still hook it up speaker level.
Best explanation I've seen that features all scenarios, and highlights the preferred one. Thank you.
Just remeber, resistans for DC, and impedans for AC, they are not the same. Multimeter measures resistans. The input impedans on the sub are to high to have significant influens when paralelled to the speakers 4-8 ohm impedans.
This is so informative. Thank you! Probably a dumb question but for the third solution, do I need 2 kickers for both my speakers to the sub?
Talked to someone at Quill & Nib. Said I could send my equipment to them, and they would walk it into your shop. =8^)
Hey Kevin, always good to hear from you and especially this video. First Off No Rush on this for a reply but sooner rather than later sis Always Appreciated, but I also understand you have a Business to run and don't have unlimited time. LOL... as I'm still looking for the System that Tickles My Fancy and fits my Room... (Though I do have that Sansui 8080 I'm having examined and may or may not sell it as well. One of those Basic's I always loved, if you remember our previous cross talks is Sansui be it Receivers 70's and 80's or Integrated. I have a short time window in which to pick up a Mint Sansui Au-555A Integrated with Wood Case known for its fantastic Musicality, but with Low Power. Which isn't really concerning as I'm sure that 10 Watts RMS from most Amps would be sufficient for many speakers with a resistance above 87 Db Per 1 Watt. Especially as my listening space is not 5 feet from anything I choose to run. That said my Only wish is lol... the AU-515 or the AU7700 didn't have their interconnects on that lousy shelf...as My First Love are those Integrates...And Now that I have your lesson on Sub Woofer Add on for I'm good to go. But any thoughts on the Au-555A are greatly appreciated. And I have an eye on a SX-990 Pioneer. Thanks as Always...James~
Didn't I include the 555 in the best of Sansui Integradeds? Their awesome. Get one if you can.
I lucked out with my Sansui au-5500 the preamp out/in are internally connected via a switch. the output rc’s signal I went off to line level input of sub. Externally jumpered would require the y-cable as you have shown.
Going to try this soon. Thanks!
Imagine how much better your readings would have been with a pair of those magic copper, designer speaker cables. 😂😂😂
AWESOME VIDEO THANK YOU FOR THE KNOW HOW
I guess I"m really lucky as the receiver I have actually has a subwoofer output on the back. It's a Harman Kardon HK3480 I plug into a Mitsubishi subwoofer which has a level control on it, to adjust the amount of bass that it produces. The Mitsubishi has it's own integrated amp, and it produces really good sub bass. I'm sure there are other models and brands that also have sub outputs, but this is the only one I have ever seen that actually has it.
Would this work with a passive sub, or does it require an active sub? I'm thinking about the old passive sitting in the garage.
I have a Fisher 500c that I'm trying to connect to a powered subwoofer with RCA L and R inputs, along with an LFE input. There are no speaker wire inputs. My Fisher has a Center Channel speaker terminal. Would I connect the Center speaker terminal to the Sub RCA inputs, using a line level adapter? Thanks so much for your informative videos.
You only need one line level to make this work correct? Thanks Great vid
Hi! Great video! Q: In wiring Solution #2 why do we have to go
back into the Main Amp RCA plugs? Thanks in advance
I connected subwoofer rca to headphone jack on receiver and it works great, why is this considered terrible way to connect? The sub sounds awesome
So with solution 1, you can't use the crossover right? The full frequency spectrum would still be going to the speakers?
I use the second pair of speaker level outputs on a Marantz 2238B. I like the way that works, especially when dialing in the powered subwoofer as it makes it very easy to compare the sound with and without by switching it on and off at the receiver and not having to power down the woofer. It's very instructive to be able to do this so easily as you can be sure you are doing no harm with the overall sound with the woofer and that it really is entirely making an improvement only. Though I do not ever plan to use a second pair of speakers in another room with it, a person that wants to could temporarily hook things up like this while setting the subwoofer the way they want, and then move it's wires over with main speakers in the first set of amplifier outputs when done. I do want to high pass the main speakers (as low frequency wise as sounds good), but have not bought anything to accomplish that just yet.
With the 1st way do the sub inputs need to high inputs?
you can connect any subwoofer with vintage stuff, just find the correct adapter and its done, i did that to vintage amplifier with new subwoofers,
I really hope someone has the answer to a situation I’ve had with 2 different set ups.
On both cases, I tried to use the second method shown in the video which is going from receiver to sub high input and from sub output to speakers. It did not sound right.
So thinking I hooked something up wrong I decided to switch the red to the black on the sun’s left high input and immediately heard a vast improvement, switched back red to red and again I have poor sound.
So again, 2 different systems same situation, same improvement by switching red to back on one channel. Yes, I’m 1000% sure the wiring is correct; all connections are red to red and black to black.
I’d really appreciate any input on this.
By the way, great video!
Good day, need to ask, is it okay to connect from the high level of the amplifier directly to the RCA of the sub using RCA to bare wire connectors? This is without using a converter. Saw a couple of premium RCA to bare wire connectors and was wondering if this is what they are used for. Would really appreciate a reply on this. Thanks.
So when using method number 1 the crossover is actually effecting the small speakers?
Would utilizing the high level input on the sub hooked to the amp then output from the sub to the speaker alter or colour the sound as opposed to hooking the speaker directly to the amp?
Maybe? Maybe try it both ways and see what you like more? Donno honestly
Hi Kevin, love this video and just subscribed. This video made me curious because you were offering solutions for powered subwoofers and old school systems.
I just finished a refurb and resurrection of a vintage audio system at my home and it incorporates old school gear and new school gear after I did a bunch of research on what I wanted to have in my audio room. The old school part is a bunch of home theatre stuff I had from circa 1997 and is the following: Sunfire Cinema Grand amplifier (I'm only running it as as stereo amp instead of 5 channel) wired in "Current Input" mode. I have a B&K Reference 20 pre-amp. The stereo speakers are Dynaudio Audience 7's and I have a Sunfire MKII powered subwoofer also to embellish the bass. I have a Sony DVP-S7700 CD player as part of this setup for those occasions when I listen to CD's . For the new school part I am front ending this system with a windows laptop to run the Qobuz streaming service in Wasapi mode and sending that signal to a Geshelli J2 DAC via a USB cable. This setup proves to be amazing and with the backend system, it would be expected but....the game changer is that DAC on the front end using the digital streaming input. The DAC creates a massive sound stage and has such fine precision across the sonic frequencies. Love my vintage gear with the modern front end! I have a another vintage amp/pre-amp combo I want to also try this with.....an older Yamaha (circa late 1980's gear) MX-1000 and CX-1000 . The amp is currently a bit broken and needs some work but that is my next project.
Cheers brother! Chris
i was scared to hook this up to my sansui so i got my kenwood out that i bought in 1993 and hooked it up on it first and it worked haha
Thanks for this video. I am converting woofer speakers into a pair of subs. Here in Brazil speaker prices are 3x what they are in the U.S. Could you make a short video on best hook-up solution, mono and stereo for passive subs?
Dude! You are the man much appreciated 🙏
Happy to help!
Thank you so much for this video. My sansui has a second set of pre out plugs and the u shaped plugs for the other pre out and in can I use the second preout for the sub?
