Currently I have HD360 and LITLE MARCUS 800.
I recently bought a used EBS NEO 112 CABINET because I can get it cheaply.
Speakon Cable has Belden 5000up + Neutrik
I connected HD360 and NEO 112 because I was wondering if the sound would come out, but the sound came out well.
My question is, the ohms and outputs of Head and the ohms and outputs of Cabinet are different. Is it okay to use it?
If possible, I'd like to try the markbass 800, but it's a little scary. I'll write down the specifications of Head and Cabinet below.

Your cab is 8Ω and will handle 300-watts rms. Ideally you want both heads to deliver less than that to an 8Ω cabinet for the best match.
The way ohms work depends on whether the cabs are hooked together (or to the amp) with parallel connections (the industry standard) or series connections (not uncommon in the 70'w and 80's but very uncommon now). Doesn't matter if you plug both cabs into the head or just one into the head and the other into the first cab (called daisy-chaining), the amp sees the same ohms load. If you hook two 8Ω cabs up with parallel connections, that drops the impedance to the amp from 8Ω to 4Ω. That lower impedance allows the amp to deliver more power to your cabs.
It is kind of like having a 2-lane road where you're just chugging along versus a 4-lane freeway were you can travel faster because there's more room for more traffic. Another analogy that might make sens to you is using an 8Ω load is like using a 1/2" diameter garden hose - only so much water can go through that small diameter pathway, whereas a 4Ω load is like using a garden hose that is a full-inch in diameter - it can put through twice as much power because it has the room to do so.
The EBS head will put out 360-watts rms and will handle down to a 2Ω load. It does not specify how many watts it handles at either 4Ω or 8Ω. I would presume, since it's a class D head that it will probably deliver 360-watts into either 4Ω or 2Ω but only about half of that into an 8Ω cab. It's common for class D amps to deliver half of their power at 8Ω that they deliver at 4Ω. However, some class D amps deliver significantly more than half of that power to an 8Ω cab - Fender Rumble 500 comes to mind.
In any case, I would expect that EBS head to work fine with your EBS 8Ω 112 cab and should drive two of them just fine too, as long as you don't turn the Bass EQ all the way up (can cause mechanical damage without melting the voice coil of the speaker). It's going to deliver less than 300-watts to the speaker and probably closer to 180-watts rms. So no problem power wise unless you do something stupid like dime the Bass EQ. The question is going to become, does it have enough power with only one 112 cab or will I need two?
I have a couple of Eden 112 cabs myself (also rated at 300-watts rms handling power) and my experiance is one works fine for small venues, but not for medium-sized venues - It takes 2x112 cabs for medium-sized venues.. I run just one of them for small venues and I'm using an Eden TN-226 class D amp that puts out just 225-watts rms. It's great for small venues but not for medium-sized venues. I bought the first cab in 4Ω because I didn't expect to use it for anything but small venues and the 4Ω impedance would allow the amp to send all 225-watts to that cab - well under the maximum power handling. I bought a second one to use at medium-sized venues because that first one just sounded so good.
Had to use my big Eden amp that would supply 400-watts rms into each of its two channels to use them because I didn't have an amp at the time that would handle a 2Ω load (4Ω + 4Ω connected in parallel = 2Ω load). So I plugged one into each channel and I had to be careful not to push the envelope (don't crank the master volume). Putting 400-watts into a cab rated for 300-watts rms is a recipe for blown speakers. I run a very clear and clean tone in my rigs, and I've blown speakers before, so I'm always listening to make sure I'm not stressing the speakers. The master on my amps determines how much power is being sent to the spearkers and I found I could easily fill a medium-sized venue without coming close to cranking the master, so I gigged that setup for a year and a half before I bought my DNS-210 cab by DNA.
Running a single 112 cab with your EBS head should be fine for small venues, but plan on getting another 8Ω cab to add to it if you want to play medium-sized venues. I would expect you could use two of those 112's with your EBS head for medium-sized venues just fine.
I would NOT recommend using the Little Mark 800-watt amp with your cabs. It will put out 500-watts into an 8Ω load which is 200-watts more than your 112 cabs can handle. That makes it way too easy to accidentally send more power to the cab than it can handle. I'd consider that "tempting fate" and just wouldn't do it. If you had two of those cabs then it would still be capable of blowing both cabs, but it's only over by 100-watts instead of 200-watts. The safest thing to do is to use an amp that doesn't put out enough power to fry your cab(s). However, I did that for about 1½-years with up to 400-watts available for 300-watts max handling cabs and it worked fine because I didn't need to push it and I play with a very clean, clear sound. Running distortion or "fuzz" makes it all be umpossible to tell when you are stressing the speakers of your cab(s). As long as your EBS head is loud enough running two 112 cabs, that's how I would proceed.
