Here is the review from Audio Science Review

If you want to play your favorite songs entertainingly, a mini stereo amplifier is the best way to go. Fosi Audio TB10D is an analog input(RCA) Class-D audio amplifier that easy to install to build your home audio sound system.
Yes, but you need to use a big power supply
That's at 10% THD.
Yes, the max power.
But as Amirm said "Cost per watt is just 35 cents"
@Fosi Audio: 10% THD is crap. Amirm tested this at ~100WPC at 1% with the included PSU. Stop your 600W marketing BS.
Yikes
at 4 ohms
Yeah, @4Ohms
It's 200w at most. But plenty good enough for the price.
When use 32V 5A power supply, the max power is about 200watts. If you want to get more power, use a bigger power supply.
You can probably squeeze "600w" out of a matchbox sized amplifier for a split second. This is just marketing trope.
A few problems with the post:
At 10% THD this will sound terrible and be bad for your speakers.
This 600W rating is achieved for a split second ("max power") using a power supply that it doesn't actually come with. It looks like you'll need to purchase that separately.
This extra PSU provides 3X the input power than the one provided (48V x 10A = 480W, 32V x 5A = 160W) so I would assume the "max" power to be a third, or 200W. Considering this is still "peak" output, I'd put the average at about half that, which leaves you with 100W, or 50W x 2 channel. Suddenly within range for an $80 stereo amp.
I thought everybody loves music at 10% THD. More is better, right?
It is very misleading to say 600W output without mentioning that a different PSU is needed, at extra cost.
OP, what product for driving two 4ohm 40W Audio Exciters and a powered sub ?
Hi OP,
Can you confirm why the price is more for this "deal" ??
Seems quite misleading to me.
From your Amazon shop it is $95.99 Delivered.
From your Ebay store it is $85.99 Delivered, or $80.99 Delivered with Ebay+
Nice find - negging as cheaper elsewhere as per above
This doesn't appear to be a bargain, more like using this website for free advertising to try & make money off the community.
Cheaper on your eBay store -
Fosi Audio TB10D TPA3255 $85.99 delivered
Also the title is misleading, you should state the output with the supplied 32V/5A Power Adapter.
@Fosi Audio
Can you comment?
Make us pay for your Amazon costs? Nah.
Cheaper elsewhere.
600W out of an amp that small?
