My head hurts
My amp head hurts
Mine too. What answer did you get for number 2? I feel like I'm in math class again 🤣
Facts! I am still so lost lol
@@gamer10884is that a Little Mark 800 head?😆
Way to much talking
Please remember, like with car amplifiers, your head will not be sending a constant power of 800W to your cabinet at all times. This is simply how much power will be sent when operating at full volume (assuming the power ratings of your head and cabinet are the same). So if you are at only 20% volume, your head is definitely not outputting 800W to your cabinet, but instead much less (ex. ~200W). So like mentioned in the video, it is alright to have a head with a bit more power than a cabinet can handle, you just have to make sure to not drive it too hard and make sure to match the impedance.
I finally understood the 8/4 ohm cabs difference. I've watched several videos in a row from different creators and this one is only one that made sense. Thank you Clay!
I've been playing for over 40 years and never paid attention to this stuff. Thanks for enlightening me.
Bro where the hell were you when I burned up my SWR head running it to a 2 ohm cabinet! Lived in a 4 plex and knocked the power out in the entire building! Damn!
Super clear and concise on all the information. Very helpful and I will be referring to this again when I start making purchases. Thanks!
It took me 4 times to understand but I did :D Thanks man!!!!! This is the best video to explain power and resistance.
I’ve been playing bass for decades and never understood this until this fantastic video! Thanks man!
Best explanation on youtube so far, well done man!
The smartest and cleverest video I've ever seen about amp's impedance ! Awesome, man !
Great explanation of how things work. It's something I had explained to me years ago and I did the physics whenever I wanted to try something new. It helped me learn things. If this video existed back then, would have saved me time and effort. LOL! Great job!
I run an Ampeg SVT-3 Pro through a Trace Elliot 1048 (4x10 cab - 8 ohms) and Trace Elliot 1518 (1x15 cab - 8 ohms). The cabs have "Input" and "Link" inputs. Use "Input" direct from the amp and "Link" for a stack. Great tone and volume no matter how I run this setup.
Brilliant and very interesting...but will have to watch it again
The information at 7:10 is wrong. Daisy chaining is still parallel and doing so with two cabs of matched impedance (8+8) will total 4 ohms.
Thanks Clay! Good/useful info!
Great explanation, I needed this thanks
Thanks! This is a good overview to follow if you use a stacked bass rig. If you don't want to deal with these issues, just use a combo amp.
Just stumbled across this! Nice one bro, great stuff!
Great explanation! Thanks
This genuinely was helpful! Thank you for taking the time and effort to post this. I surely do appreciate it, and I can't be the only one!
this is what the guitar tech explained to me when i came into the store looking for a new bass head 30 years ago, great video i wish i had information on hand like this back then .
I dont know why people buy combos unless you live in a apartment. Save a little longer and get a 4x10 or 2x12 and a head. Then save more money and buy a 2x10 if you want portable. Combos in my humble opinion are a waste of money for bass players. My 4x10 sounds luxious even at low volumes. My drummer works cement all day so I don't bitch about lugging a 4x10 to a gig. Its worth it. The Heavy good shit is harder to steal too lol.
This video is awesome, I've learned alot
FINALY!!! Thanks man.
I have a TC Electronic BG250 combo which I found to be more than adequate for pretty much any bar gig. Anything larger, I “DI” it into the PA which you would likely be doing regardless! Got rid of my big GK rig and never looked back.
I use a Mark Bass Jeff Berlin Combo 15 and a Mark Bass 2X10 as an extension cabinet. I can also just use the 15" combo solo. I bought a Mark Bass amp to power the 2x10 cab for gigs that it'll handle. That way for the big gigs, I stack the 2x10 on the 15 combo but use the other head on the 2x10 giving me 300 watts per cabinet. I run a line out from the 2X10 head to the balanced line in on the combo amp so each cabinet can have it's own unique sound . That configuration gives me the ability to dial in super lows, crisp highs and punchy midrange because each cabinet has it's own amp and eq etc.
Is your amp head a little mark ii ? What ohms do have your 2x10 and 1x15 set at when stacking to give you the 300 watts per cab ? (Just curious , didn't know it was possible)
@@yeewhiz Little Mark III and the 2x10 is 8 ohm. I only get 250 per cab when stacking but I often use two amps with Little Mark III powering the 2x10 cab and the Mark combo powering the 15, that's how I get 300 per cab. I use a separate amp for each cab and run a line out from one amp to the XLR in on the other. Each amp is 300 @ 8 ohms. Really cool with my Rickenbacker in stereo giving me one pickup per cabinet. Using 2 amps gives me the ability to have two totally different EQ settings for each cabinet too.
@@yeewhiz I use a Mark III with the 2X10 and the Mark combo amp with the 15. They both put out 300 @ 8 ohms. When I'm running both cabs off the combo head it's only 250 per cab. Using two amps gives me the option to use a different EQ for each cab too. Pretty cool. I just run a line out from one amp to the input on the other and then balance the volume as needed. Really cool with my Rickenbacker in stereo mode too. I have one cab and amp per pickup on the axe.
@@hermonbluesmaclin-theboogi6830 Thanks for the insight. I recently got the 2x10 because I like the clarity with the higher tones. I've had the 1x15 cab for a while and decided to get a 2x10. They both sound good for the purpose they serve. I was just curious to try my little mark III on both amps. Having an amp for each for different EQs makes perfect sense.
@@yeewhiz They definitely do sound great either way. And you’re right, the clarity of that 2x10 is better than the 15. I like the 15 for my reggae gigs.
This was great. When I was a kid playing bass back in the 70s, I used to beat my head against the wall after blowing up bass cabs.
I now have EV’s an old SWR basic 350. Burgundy face. It’s good down to two ohms, has a tube pre for warm sound, and you can find them for about 300 bucks all over the place. It’s a steal, grab one if you can. 450 watts at two ohms.
Great video 🤘😝🤘
Thanks bro!!! 🙏
I have a MESA 8 10’s Bass cab that has the parallel out that you mentioned and I would usually put workingman’s 410s behind the Drummer . What a great thing that MESA has included in those old cabinets, I wonder if they still do.
Hey man, nice vid. Was trying to explain this concept to my guitarist last week. Dusting off the old physics formulas, good fun.
I have a Mo'Mark 500W head with the HE tube preamp, and a 104HF cab. Saving up for a 151 cab to put underneath for the monster rig. With my Sansamp it sounds mega!
Good explanation. But why do you shout it? It’s really hurting my ears.
Great vid!
Im confused.
I check speaker cable with my muti meter with both cab connected to each other and it halfed the ohms.
From there independent tested value.
I MAY be wrong...lol
Thanks!
I use a Big Bang, new york 121 and a 210p in series and its great! ! !
What’s up brother, this is actually the first video I see from your channel and best believe I subscribed, I have a quick question for you, I’m currently running the Markbass 102p combo amp, do you think I can ass another 2 10s to it? Like will the head support that ? Thank you
Yes!!! Thank you!!! !Nation4Life
I'm pretty sure all bass cabinets are wired in parallel which means if you daisy chain 2 8ohm cabs, it becomes a 4 ohm load. if they were in series, it would be a 16ohm load. Maybe I'm wrong as I'm not a rocket scientist, but that makes sense to me. The rest of this video is spot on.
That’s the way I understand it also🤔
Me too!! That is the way I run my guitar cabs,, so when he said ohms doubled,, I was really confused
video helped me!
so for your 2x10 cab you basically "daisy chained" an attenuator of some sort to increase the resistance to that cab? can you explain in more detail?
Thanks for the info. This stuff is hard.
God bless you
thanks for explaining
I am an electrical engineer and missed the math
my rig includes a 2/12 and a 2/10, both with a tweeter
two heads and a passive mixer to drive both amps and
control the balance between the two combined rigs
for sound changes after setup only the onboard EQ on my bass is used
some more combinations possible
first rig I built contained 19" gear:
Rack Tuner,
19" dual compressor,
active crossover
five band parametric EQ
stero power amp
the two mentioned cabinets
too heavy and less versatile compared to my current setup
thanks for your good work
Man, this stuff can do ya head in. Hope that helped you guys out if you were really struggling to understand Cabinet and Ohms. I will add here that on more research it seems that MOST cabs tend to have Parallel connectors and just don't state it on the back but not ALL! So if you aren't sure if they are or not always connect each cab to the Amp Head individually to play it safe. Only Daisy chain if you amp head only has one output and you have to.
It really would help if he were speaking American English. In addition to the subject matter being a little confusing, and fast talking, there is a language barrier. However, I do appreciate the attempt to explain.
@@terrimac7993 It really would help if Americans spoke English and not that abortion called American English and leant how to spell socks. And pulled their head out there own arse and started to use the metric system
Fix that up for us will you mate?
I watched your video several times. Thank you for the good information. I did discover that my Behringir BXD 3000H Ultra Bass Amp Head is rated at a minimum 4 Ohms and 300 watts and 180 watts at 8 Ohms. My Ampeg 2x10 Portaflex Cab is rated at 8 ohms but wired in parallel so I can actually connect two 8 Ohm cabs and get the full 300 watts Does this make sense? Thank you again.
thanks a lot Clay ! still , if i connect an extension cabinet to my compo amp ( it has an output for that ) , will the connection be in series or parallel ? how do i tell ? thank you
Hugely helpful. I've heard a lot of bad things about Markbass gear dying in the middle of gigs, which has made me reluctant to drop the $ on the stuff. Now, I'm wondering if it was self inflicted by the owners improperly pairing their rigs. I'm def bookmarking this video for my next equipment upgrade, likely to be Markbass...
Well, I'm very sorry to say that it happened to me after 6+ years of reliable operation playing at some pretty loud club gigs, MB Little Mark III combo with 2 x 10s connected to a MB 1x15 extension cabinet except during practice. Thankfully it died at home during practice - blew a fuse, which blew again after replacement within minutes. I spent a few hundred to have it repaired and the same thing happened again, within minutes. After having it repaired again I brought it to GC (where I bought it) and traded it for a couple of other amps. They have a great look and good sound and I love the lean back option for the 2 x 10 combo. Maybe I should be happy to have gotten 6+ years out of it?
I have the little Mark 800 also with the Mark bass 210 & Mark bass 115. I’ve always Daisy chained them but now I’m wondering if I’m overworking the 115. I was also thinking of moving up to the 410. Any advice would be appreciated
New subscriber here! I just bought a 4x10 GK cab with a peavy headliner 1000 head. Is this ok or do I need to add a cab?
I had a semi tube (those fake tubes) 60 watt custom build (originally owned by my uncle) bass amp with a yamaha 2x15 and 2x10 hartke combination...
The speaker blew and i was about 17 so i ditched the amp completly...
Ran a hartke lh500 with a 450 watts 4x10 after switching that up by buying my guitar players peavey tmax, tore out the amp and used my 4x10 with a 1x15 mix.
Thats still owned by me but i switched to a markbass amp with a mesa 6x10+1x15 and there i hit that sound that i want!
Solid State amps can usually run at 4 ohms (the old Sunn Coliseum could run at 2 ohms, which will blow most amps out, but Sunn went out of business some years ago and they are hard to find now). I run a Mark Bass head that puts out probably 500 watts at 8 ohm, but I run another cabinet out of the second output. I have a 4x10 cab at 8 ohms, and a 1x15 cab at 8 ohms, so that running in parallel, total 4 ohms, which allows my amp to run at 4 ohms and puts out 800 watts. Tube amps with an output transformer may be able to handle a little more variance in the output impedance, but if I ran my Solid State amp into 2 ohms, I would likely toast my output transistors. I have yet to use 800 watts, as this would be very loud. My 4x10 is the same Mark Bass cabinet in your video, and my 1x15 is meant to handle 350 watts, so I could possibly blow it out if I went full throttle. And when you're pushing a cabinet to it's rated wattage, you may still overheat and blow out a speaker. If your speaker is making scratchy distortion, you can gently push on the speaker cone. If you hear scraping, you have blown your speaker. If it won't move at all, you've sent the speaker into total meltdown. If I so blow my 15, which is unlikely saying I have only played small venues and have more than enough power. I will probably replace it with a Neo 2X12 cabinet.
I am building a similar rig with the 102 HF and the 104 HF CABS and was wondering were i can get the “inline impedance increaser”?
Hi there. Can you connect the bass guitar combo to a mixing table using a cable or is it better to use a microphone placed in front of the combo as you normally do with an electric guitar amplifier?
Blessings from Porto, Portugal.
If your head has an XLR out or cabinet emulation out then yes you can connect direct to a desk. If your amp doesn't then it will need to Mike up your cabinet. It will sound bad if you connect direct.
Also if you run your amp with no cabinet resistance from the speakers you can damage your amp due to too much current. Always have a cabinet connected to your amp, even if you are going direct!
Just starting out to play bass what amp would be recommended for an amp? Tube, Valve, solid state, hybrid,simulated amp? Thanks
Great but have 2 questions, I have an 18" powered sub-woofer running from my amps DI, do I need to consider this at all in the ohm calculation?
The sub-woofer has a DI through which I intend running to another identical powered 18" sub-woofer as they are separate powered units I kind of guess no problem? Certainly haven't had a problem running 2x10, 1x15 & 1 powered 18 sub from the DI as yet but in house I'm not running above 2 on the volume knob. In case your wondering why - my modified bass is tuned an octave below normal so it starts at E0 i.e. 20Hz.
If you daisy chain the cab that is getting too much power would that work? I had bass rig I put together that consisted of a Peavy 18" sub cabinet, EV 15"x10" cab powered by Gallien Krueger 700rb. Ran a Fender Bassman 4x10 that I rigged to only use 2x10 and took out two speakers and the tweeter. Pretty awesome sounding but never got the chance to test the limit of the power before it was stolen. Any thoughts on the potential problems being set up this way
What’s the best Mark Bass head for a Mark Bass (2) 10 cab with a Mark Bass 15 on the bottom? Both ratted at 8ohm 400w each.
Thanks for this Clay. I sort of knew what goes on with impedances etc but your brilliant explanation has filled in or the gaps. As a guitarist & bass player there is one question I have never had an answer to. This is as follows....WHY does a 100 Watt VALVE amp sound so much louder than an equivalently powered SOLID STATE amplifier? I use both kinds of amps & there is definitely a huge difference audibly. In other words why is a valve watt seemingly louder than a solid state watt? By the way I use a Mark Bass 800w amp head with a tiny pre-amp valve that can be dialed into the mix. I also use a Mark Bass 4x10" which is rated 4ohms. I believe this is similar to your rig in one of its configurations. I would like to add a 15" cabinet & bi-amp the 2nd system to keep the impedances correct but carrying this gear will be ridiculous at my senior age. The speaker magnet technology has improved massively & Neodinium ceramics have lightened cabinets somewhat. However the cab size situation has not inproved that much so I would still need a truck to carry this gear :)
Good question, I saw that tubes are louder than solid state(on a guitar amp vid), smaller tubes powering the big tubes, but I don't remember the exact reason. What I do know is that tube amps are a helleva lot heavier, haha, ugg.
> WHY does a 100 Watt VALVE amp sound so much louder than an equivalently powered SOLID STATE amplifier?
Because Watts are not really a great way to measure volume.
When you say that you are running the two speakers in parallel do you mean in two separate speakon sockets at the back of the amp , if you do a lot of amps only have one socket so what do you do then ? Sorry if I’m being thick lol
Hi! I have a GR Bass 212 Slim 4 Ohm 900W RMS (AES Standard) cabinet. Just for home playing! Sould I buy the 800W bass head, or for home use it would be enough the 350W bass head? Thanks a lot! ;)
Short question; Combo 400W ( 200W RMS ) min 8 ohms ouput: Can i use a 450W 4x10 bass cabinet as external?
Good info but... where’d you get that lamp??
It does not matter, until have the speaker coil spat out of the speaker. In general, to get the max "watts" out of your amp, you need to MATCH impedance, 4, 8 or 16 OHMs.
man with all due respect im going to buy a mark 151p combo and im going to connect it to the mark bass new york 151 its an 8oms cabinet
ive been playing mark bass gear for ten years i have a 800 tube head plus two 8ohmn cabs always have daisy chained cabs,even mark bass suggest this in there manual,cheers
I have a Dark glass head and it has a 2 ohm setting. Can I run a 2.6 load? 8 and 4 ohm cabs?
I'm planning to connect a second 2x10 8OHMS 400W bass cabinet do my Little Mark 3 head. From their FAQ it was said that from each head speaker output i connect 1 cabinet as showed at 8:24. Or connect one of the speaker output to the first cabinet and then link it to the second cabinet again as showed 7:19. But it doesn't mention nowhere about the doubling of the impedance to 16OHMs or that will run quieter if i connect cabinet to cabinet it just says that either way you connect it you will run at 4OHMS but you say otherwise. You also have Markbass setup so please let me know what should i do. This is really weird i guess it should have worked great/same either way. Thanks
Got it about the omhs, still have a doubt about the wattage, cos i own one amp of 4 omhs and 300watts and 2 cabs of 8 omhs, one of 300watts but the other has just 150watts. Do I risk to damage the 150watts cab if I connect both cabs in parallel to that amp???
which cable should we use for the parralel connection? Because mark tube 800 just have one "speaker out"
Can i ask something??what happens when you plug-in your e.drums to a bass amplifier?
I have the same 4x10 cabinet. the back says its 4 ohms, but when i look online it says 4 or 8 ohms. it even shows it in this video. does that mean its regularly 8 ohms but when wired in parallel with another 8 ohm cabinet, its running at 4 ohms?
Hi. And if the cabs are 400w8ohm 15' plus 500w8ohm 12' and the bass head 500w min 4ohm only one output ...can it work and doesn't exploit de bass head? Thx
Great Vid!!! New Sub here! thank you!
Note that most EBS amp run 2, 4 or 8 Ohm cabs.
Thank's Clay this was very helpful! I have a question about 2 ohm amps, i have a Sunn 1200s bass head that runs at 2 ohms according to the manual, are there 2 ohm cabs out there or can I use 2 4ohm cabs?
I only know about Darkglass DG108, that have the 2ohm imput, but looks they discontinued this cab series
I have a hartke vx3500. 3500 amplifier with 350 watts. It has 4 10" speakers at 4ohms 100 watts. I cant find a replamen speaker. Will it be ok to use 8ohms to replace all of the speaker
Great name, my friend.
8:14 what if you only have one speaker output on your amp head like mine. and I herd it was fine to daisy chain cabs
I'm so confused, but this helped a lot.
Gj and ty man :)
I have a Markbass 104 hf it’s says 8hm what amp should I buy from Markbass I’m new to this any idea !?
H**P What is the specific type of FUSE required in replacing a blown fuse for the Little Mark III?
thanks for sharinG!
good video!
If I need more power for a gig I’m entertaining the idea of adding a fender rumble 115 v3 extension cab (600 watt 300 rms 8hm) to my ampeg ba 210 v2 ( 283 watt @ 4ohm, 450 @ 8) via the extension out jack.
Other than offending other bass players do you think this is an advisable pairing spec wise?
My thought process is to add a 15 for more low end thump where I already have 2 10’s handling the punchy sound.
I’d love to get some feed back!
Thanks
I've done that, but splitting the difference, like he explained here, I found that I wasn't getting the best out of either. I always ran with 1 15, but I wanted to add a 2×10 so that I might actually hear myself over the obnoxiously loud guitarist I've played with. I dabbled with a 4×10, but I like the heavy hitting of a 15. That being said, the best bass cabinet I played was an old 2×12 offset.
In my case amp is 2 ohm stable and I have two 4ohm cabinets, which allows me to have more headroom and very huge sound on the stage, it's awesome
hey i have a question, you probably just answered it but i wanna be 100% sure, my combo amp is 2ohm which alone puts out 350w…but can achieve 500w with an external cab….how many ohms does the external cab need to achieve 500w ??
If you want to achieve the maximum power from your amp you need to have two 4 ohm cabs this will give you the best performance for your amp and make your amp see a 2 ohm load and nice headroom
I’m planning on pairing a 500w 4 ohm amp head to a 2x10 4 ohm cabinet but it’s RMS power handling is rated at 400w. Would this amp head being 100w over the power handling cause any issues? Also I’m not planning on doing gigs or shows this is just for practice.
From my research, you should be fine. Just don’t push it hard and pay attention to your sound. Don’t let the cabinet complain and overheat for long
I'm confused because markbass amps all have one speakon out so how do you wire 2 cabinets parallel?
My Bergantino Forte goes down to 2 ohms
Another Clay here!
Hi clay, Im going to buy a new rig and I'm looking at the tc electronic bq500 amp and their k-212 cab what do you say about this setup ?
Good setup man. The TC stuff is sounding great at the moment.
Also have a look at the GK ultra light stuff. What sort of stuff do you want to play? That will really determine your amp choice.
So if in got this right lol.
I Run a Peavey Minimax 500 watt. To get 500 watt max power. I could use 2 8;ohm cabs . Rated to handle 500 watts or more?
Reeespect!
what happen if i connect a 500 watts at 4ohms bass head to a bass cab 400 watts at 4ohms? is it ok?
So surprised so many guys don’t get this. Playing in bands I was always explaining ohms / watts to guys. Crazy.
you must be a very clever little sausage then. Give yourself a pat on the back.
thanks man that helps a lot
So I should get an 800watt 4x10 at 8ohms??
And use that by itself and then get another one if I want a stack?

Can someone please tell me I have a Svt 610 Ohlf Impedance 4 Ohms Power 600 watts Rms 1200 Peak what is or would be the perfect match watt amp head that would go with the cabinet! Please help
Hey you mentioned towards the end about the impedance increaser your friend made so that each 10inch speaker would get the same power. Is this absolutely necessary or is it more of an "OCD" thing? Because the way I see it, the 210 should be ok with the 400watts, despite it being annoying that things aren't balanced with the 410 cab.
He wanted the applied wattage to each cabinet to be the same so the sound would be more balanced.

Made with HARPA AI
please explain Clay , how come compos have an 8 ohm speaker in them ? do they run at half their nominated power ? thank you
You would need to check the specification sheet for your amp. But, with combos, generally, if it has an "external speaker" port, then it runs at about half power. Add an external cab and you will get full power.
So I also went with Markbass speakers, and I'll be hooking up a 4x10 markbass cab up to an 800W Little mark head, and plan on getting a 1x15 cab as well. Looking at the back of my amp head, I see two outputs, one that says Speaker Cable and the other that says "Class 2 Wiring", does it matter which cab is connected to which output or not?
Doesn’t matter. Class 2 Wiring just means it’s generalized as safe from electrical shock and doesn’t pose a fire hazard under the electric code. They’re both speaker outs. The LM 800 tube amp just gives you two different speaker output options: the top one being combo jack of Speakon or 1/4”and the bottom one being the regular 1/4 inch (which I actually wish they would have just done both Speakon jacks). Use both of them, one going to one cab and one going to the other, and you’ll get the parallel circuit he’s talking about in the vid. I actually have the same setup, so here’s how it would look: Top (Speakon) speaker output jack running a cable to my 4x10 cab. Bottom (1/4in” jack where you saw ‘Class 2 Wiring’) running another cable to my other 2x10 Traveler cab. Now both cabs are separately connected to the same amphead instead of amp to cab then cab to cab (daisy chain). Keeps it Parallel.
DISCLAIMER: According to Markbass themselves, it’s safe to daisy chain so I don’t know who’s right or wrong necessarily. Nerds are gonna nerd.
Hey man serious question, how can I buy one of those cables? I have the same setup and I don’t my 2x10s cab to over heat or anything like that 🥺
Did you find a solution?
It looks like you are a markbass fan :) In your opinion, which markbass combo is the ultimate one ( for practice and gig ) ? 😉
THE BIGGEST YOU CAN AFFORD..THE MARK HEADS DONT SOUND DIFFERENT ENOUGH TO EVEN WORRY ABOUT..THE MORE DRIVERS THE BETTER...
102 will have you covered for most stuff. Have a 4x10 for bigger gigs if you need it. You will be surprised just how much air the 102 combo can move!
Impedance increaser is just a resistor lol
Its a secret technology for consumers )
as I am shopping for a new rig. I have a 3 part question.. your amp is 800 @ 4 500 @8. If you have an identical 410 cab will the 4 ohm version seems louder then the 8 ohm version by itself? will running the 4 ohm give me more headroom and volume?
Running more speakers with two 8 ohm cabs will give you more volume than running one 4 ohm cab with a higher wattage vs the 8 ohm speaker .
will this work?
