Cheap 2.1 class D board amplifier

[dafreaking]

Just now i tried the amp using same 12v 1.5A adapter and its working, i know power is very less for the amp but i just wanted to test the amp.
I will try to arrange more powerful brick for the same.
Ha e you made case for your amp? Can you guide me for the same? Or can you please give me some lead for case?

Sorry I haven't as yet. (shortlisting boards, etc...)

Making one out of acrylic might be a decent idea but it all depends on how much you want to spend and how good you want it to look.

Alternatively you could look at 3d printing something

How many speakers of your sony 5.1 you are using? What is the ohms of your sub?
My router adapter is 12v 1.5A will it work with amp? I just want to try it to check amp working or not, is it safe?

2.1
12V/1.5A safe, just keep volume and bass minimal. For best performance use 5A or above adaptor with voltages less than 20V since you are using 3 Ohms spk
For case , you can repurpose any old set top box or router box-visit a local scrap dealer. Plastic is easy to work with, compared to metal. Requires no special tools, just use hot nails , xacto knife etc to make holes.

Hi, got a TPA3116D2 based Aiyima 2.1 amp. The stated output is 50+50+100 watts (4 ohms) at 24V. However the bundled adapter is 5A/24V. How much power output can i reasonably expect to get from this combo?

5A/24v can give you 120W max btw from where you got this combo? And how much you paid?

I got my relative to bring it from US. Got a good deal -

Robot or human?

So with a 120w supply will be getting only (about) half the power?

Yes. You need something like a 24V 8a + adapter
