Hopefully this is the right area but if not feel free to move it. Each of these baffles has four 4ohm drivers wired series parallel for a 4ohm load per side. Is it okay to then wire them both together in series for an 8ohm total load to connect to a single plate amp? I'm a bit new so want to be sure. Thanks!

You are correct. Each 4-woofer series-parallel load is 4 Ohms. Wiring two 4 Ohm loads in series results in an 8 Ohm load.
But keep in mind that, with this connection method, the amplifier power is essentially shared equally between all drivers. So each driver will receive 1/8th of the power that the amplifier can deliver into an 8 Ohm load.

With four 4 ohm drivers per side you can only get 16 or 4 ohms or 1 ohm! Unfortunately, 8 ohms is not do able.
To be clear, four 4R drivers in series-parallel is 4R.
Two 4R speakers in series is 8R.
The answer is yes.
As you can see, others are confused on this, as well.
And as always, observe proper phasing.

"wire them both together in series for an 8ohm total load to connect to a single plate amp?"
Each baffle is wired series parallel at 4ohms. What I did was connect positive of one baffle to negative of the other baffle and then positive and negative from each to the amp. Essentially the same I assumed as connecting two single 4ohm speakers in series for an 8 ohm load. I hope that's clear enough.
Thanks so much! It confused me for a bit but then it occurred to me to consider each speaker set as one unit. So regardless of the numbers of drivers I should deal with each as I would two single 4ohm drivers that I wanted to connect to an amp.
Just make sure you observe the polarity, so all the woofers operate in unison.
Another thing that may not be obvious. The wiring must be symmetric or some drivers will be driven harder than others.
That is. all drivers must receive the same voltage from the amplifier.

It seems easy to achieve...
He already has each panel wired series parallel. Now he just want to put two panels in series.

What the goal put together two open baffle speakers?
Each OB panel has own polar response. What happens when I put its together?
depends where the crossover point is
below certain frequency, woofers are omnidirectional
I believe his goal is to increase bass
nothing wrong with that
he has one midrange and tweeter on top, should be ok

You were able to sum that up so much better then I did! Haha
They're connected to the amp now and working wonderfully. I'm very pleasantly surprised at the amount of bass these are able to produce. Being both OB and 6.5" drivers. They sound wonderful! Now to get my mid-bass/mids sorted. I have to run the crossover for the subs all the way up at 160hz or there's a frequency gap and the Tang Band mid drivers just seem too pushed running "full range" without the crossover. Going to try some 8" drivers I have for the missing mid-bass frequencies. I need a frequency measuring setup. One thing at a time I guess. 😉

Eventually I'll have another amp so there'll be one for each baffle. Right now this seems to be working out okay.🙂
