whats better for a battery powered setup?
12v batt into a DC-DC stepup boost converter into amp or a +/- DC powered amp with a +/- dc boost pwr supply to go with it?
noise issuses with a DC-DC stepup boost converter?
better THD and S/N with a +/- DC amp?
ive been looking at the amps made by Yuan Jing Audio
DC:
Yuan Jing Audio - ON SALE! - TAS5613 Class-D 150W STEREO PurePath? HD Amplifier Board - USD $39.50 - Class-D & T
+/- DC:
Yuan Jing Audio - IRS2092 Class-D Mono Amplifier Board [200W] - USD $29.80 - Class-D & T
they also make a 12v dc to <45v +/- dc power supply

is the +/- DC pwr supply and amp combo a safer bet? as im finding it hard to find a dc-dc step up converter.
ive ordered this dc-dc stepup converter to see whats it like:
Free Shipping 6V 40V 0 36V DC Converter Adjustable Buck Converter Digital Indicator Light Voltage Regulator-in Converters from Computer & Office on Aliexpress.com | Alibaba Group
waiting for it in the post. would do you expect ill get? lots of noise floor? are there better banded ones i can buy if so where because i cant find them.
Or would i be better off with a car amp?
im finding car amps problematic as there ether too powerful or under powered wheres with a amp board and datasheet i can limit the max watt out by setting the input voltage 🙂.
how would a car amp be when powered via a mains PP, any err ground loop,noise issues things?
my speakers are some small pa 8ohm ones and i know that some amps like the hifimediy T2 can put more power into 4ohm than 8ohm. Most car amps dont say if they are ok with 8ohm speakers, while i would assume they would (at half of the 4ohm rating) im not so sure if its that simple any more. for example the rainbow car amps and only listed with 8ohm speakers mode and not in 4 channel mode.

ive done lots of researching but ive reached the point where i feel i need reach out and ask people who are knowable 🙂.
ps. if its the case that one wants an amp that can put 75% max of the peak watt rating in constantly into the speaker? (my speakers didnt come with a rms rating grrr) then my stereo set are rated 100w so i believe i want a amp that puts a max of 75w into them and i also have a single speaker thats rated 150w peak so i think around 112w constant max. now considering the other one of what used to go with this one got broken when they where used by a band and the amp wasnt overly powerful, something like 80w peak. but somehow the other speaker got knacker. admittedly this was a band with gitars so i guess the amp was peaking all the time and so the speakers reached there limit 😉 , what do you say? would you advise amps only rated say 50% instead?
Thank you for your time.

doh! its the wrong one. thats what happens the one time when i "just get on with it" and put a order in and when im tired.
well i needed a buck/step down converter anyway. ive order a boost/stepup now
thanks for pointing out.
heres the step up ive ordered:
