Hey guys.
Do you guys know of any small 2.1 or 2ch amp boards that have reasonable power output? for what they are hahah🙄
I have a small amp board about the size of the palm of my hand with 2x tpa3116 chips on it and it is loud for what it is but I was hoping to get something a little better if possible as I know there’s a ton of different amp modules out there with various amp chips but it’s very hard to do research as you really have to try them…hummm…..but it’s worth asking the question.
Cheers

Those 3116 amps are the best for the cost using common laptop power supplies that I’ve seen.
It makes a difference to get the load optimized I’ve noticed, 3-4 ohms using a 19v supply can sound pretty good.
The 3255 is good I’ve heard, haven’t tried that one myself however. That will require a power supply of course.
Might look in the class D area of this forum for more on that one...

Thankyou for your reply,
Yes I have a couple of TPA116 boards and they are good except one has a hiss but that’s the design of that particular one. I was hoping to find one that has a little more power. I know you can’t expect loads of power as they are very small and usually use surface mount chips.
I was thinking these??? it’s a little big for the space but I can sacrifice a little bit more space providing it has more clean output.
the Wondom one states 200w but even if it's not really 200 watts that's fine as long is it's about 100watts or more of clean power.
Cheers

The Power amp is only one part of the equation, the big question is what will you feed them from?
If the same old power supply, power out will be exactly the same as before.
Plus you ask about reasonable power output but then mention 3 x 200W boards?
What am I missing 🙂

I can feed them what ever, like I was hoping the lower the voltage the better BUT Then the current draw will increase and the power output will go down too.
I was hoping around the 12-15v mark, I know the amplifiers do better at higher voltage that’s why I was wanting heaps of head room with power output. Plus some amps like these they tend to stretch the truth with output as they lower the impedance, crank the power voltage right up and rate it at 10%THD and then slap 200w on it when it’s kind of half the advertised power. Not all companies do that but my gosh it’s hard to find something that isn’t misleading these days!!!
Also you can’t rely on what chip it is as I have a couple of TPA116 boards with various output powers some vary a lot so I guess it is to do with the design also not just the chip😱
Cheers guys really appreciate it 🙂

A 15 VDC supply will only get you 10W output - max. You need to power your amplifiers with sufficient voltage to swing the corresponding output voltage and with sufficient current to drive the speaker impedance. Class D may be efficient but you are still bound by physics to give amplifiers sufficient power for the task.
