Extension cab ohms

I have a question:
Ok I have a laney cab with 4 16 ohm speakers running parallel making it 4 ohms.
Now, I plan on using it as an extension cab on a acoustic 135 2x12 combo.
The combo has 2 16 ohm speakers run in parallel making it an 8 ohm head.
So basically I have a 4 ohm cab and a 8 ohm amp.
Since all the speakers are 16 ohms what are some suggestions for me to be able to run the 412 cab and the 212 combo together?
Also, there is no where on the amp that says how many ohms it is...

just plug it in, it's solid state.

It's not going to be possible to run all the speakers you have together at 8 ohms. That's a lot of speakers though....Why do you need so many...?

I need all the speakers to be ridiculously loud.
And I know I won't be able to run all speakers at 8 ohms. I need to figure a way to make it all right/matched.
I already know that I'm going to change the speakers in the 212. Thinking about eminence cannibis Rex...

My laney 412 has 4 eminence Lady Luck speakers and I am really happy with them...

It will sound better this way

It's exactly what I did and man, it's loud as fuck...
I'm quite pleased

I still want to know the "best" way to run it.
I think I'm going to swap out the 2 12's in the acoustic for some cannibis Rex speakers. I just need to know what ohm speakers would be the best to compliment the whole setup..

Your amp has a minimum suggested load. Don't go lower than that and you'll be fine. Google it and there are tons of explanations about calculating loads. If you run your 8 ohm cab and your 4 ohm cab the total load should be 6 if my drunk math brain is right. That should be fine.

4 + 8 ohms will be lower than 4 ohms.
Acoustic 135s go down to 4 ohms, I read.
I don't think it'll be too big a deal.

Thanks, I appreciate it.
I'm playing out of it and it is fine. It's ballsy. The opposite from my randall...
I'm not going to mess the the ohms and put 2 16 ohm cannibis Rex in the acoustic.

Or, if I got 2 8 ohms speakers that would be 4 ohms, and then the head will match the cab!

(sober me) Terminator is right. like I said, drunk math... Sorry. It would be more like 2.6

I kept last night drunk replies simple.
Lower ohms always sound better til you melt the transformer.
I bet the pickle has some real lows now.

Yeah the pickle and the rat stacked was shaking the whole house!
My wife walked into the basement while I was playing and was like
"Fuck! That thing is loooouuuuuddddd!"
And I just smiled and said
" I know, it is, isn't it..."

I appreciate everyone's input. I was just over thinking it...
I guess I lucked out because it all sounds great....
