Any boards out there you'd recommend for newbie easily make multi channel amp? Hypex Options way to costly- I just want 30-50W for my tweeters and 100W for my woofers for all 7 my bed layer DIY speakers. I see Hypex you can sting enough modules to a 1200W PSU but that's big bucks I dont have- so looking for something similar for us normal people that don't have thousands sitting around and something we can di our toes into the murky waters.

For 30W tweeters I recommend TPA3110 PBTL $1 boards to convert into ABD mod.
For woofer if 4 ohm you need $12 TDA7498e wired PBTL.

Check out the all in one amplifier module at this thread, is this the multi-ch you want to build?

I have the AIYIMA TPA3255 4 channels, and I would not recommend it.
This thing does a really loud pink noise through my HF108 compression driver (conversation level noise, not a simple hiss from getting your ear against it!). hypex nc400 is almost silent when plugged through the same DSP & driver.

Oh, and I just tested my 3E Audio TPA3255 which hisses just as bad as the AIYIMA.
Know that my compression driver has a sensitivity of 108dB, so you might not hear anything with your setup!

Ok here's a stupid question how many can I run via a PSU? I don't mind adding two more "plugs" to my mix haha. I'll need to later run 7 of each.
Hiss is lower when not using the minidsp shd. Yet, a nc400 will show none in the same chain.
You ruled out hypex for costs reasons, be aware that (much) cheaper options like tpa3255 are far from state of the art in their Chinese implementations.

7x30=210W plus margin you need a SMPS 24v 10A minimum if your tweeters are 8 ohms. If 4 ohms, 18v 15A. Tell us what are the impedance of the woofers.

You can. For the woofer 100w amp is a problem. Most 3255 boards are advised to run with 36v supply. Look on youtube power measurements, most fail above 2x70w. Ali has high power ones which require dual supply. Have a look here, from Ali the same TPA3110 is $1.

Class D amps have two types of modulation, AD & BD plus mine ABD which cleans off harsh class D character.
On Ali I found many 24 10A without shield SMPS to be used inboard for less than $10.

This Amp is only $5.4+ Ship. It can be powered by +/- 58v to deliver 150W @8 ohm. It is irs2092s base. Ask advise, I know nothing about its sound quality for woofer.
How many woofers you need to power, also 7?
