This is a great amp for the price. The TPA3255 is a bit of a beast. From crap outputs like a tv or a low/mid range motherboard there is some signal noise which is unfortunate. I'd recommend a DAC if you get this, also upgrade to a 48v PSU for another $25 or so. This is probably the most power out of a mini-amp you can get for under $100.
These are the specs from Texas Instruments website:
Total Output Power at 10%THD+N
315-W Stereo into 4 Ω in BTL Configuration
185-W Stereo into 8 Ω in BTL Configuration
600-W Mono into 2 Ω in PBTL Configuration
Total Output Power at 1%THD+N
260-W Stereo into 4 Ω in BTL Configuration
150-W Stereo into 8 Ω in BTL Configuration
480-W Mono into 2 Ω in PBTL Configuration
Note that you do have to upgrade the power supply to 48V if you want to get the 75w per channel, otherwise you'll be getting about 56w per channel out of the box with the included 32V PSU.
But 75W per channel at 8 Ω is still really good for an amp of this size and cost, it is similar to most low end receivers that cost $300 to $600 (Denon AVR-S760H for example)
Oh suuuure it will output 300 watts. Right before it bursts into flames because you'd have to overvolt the sh!t out of it to obtain those numbers. I'm sure it's great for bookshelf speakers and very efficient larger speakers though.
With the included power supply (32V 5A) this baby puts out 77 Wpc @ 4 ohm and 48 Wpc @ 8 ohm. Thats pretty good for the price and size; signal to noise is not great though.
For the low-end, at 20 Hz, max power drops to 55W @ 4 ohm.

I have this driving a set of large tower speakers. It's really great and super small! Just and FYI I got this for $64 early December. They hiked the price up and added the coupon so don't feel rushed this is pretty much the normal price.
I've read somewhere that class D amps aren't great for powering transducers vs Class A/B amps. I'd be curious how this would power a pair of Earthquake transducers vs the current old school Rotel amp I have making them shake my couch now. Anyone have experience with this amplifier to power some tranducers/bass shakers?
I believe my old school rotel amp is rated somewhere around 100 WPC RMS at 4 ohms, I suspect the ratings for this are dynamic?
I'm not sure these would be strong enough to power earthquakes without an upgraded power supply unless you're running them at low levels.
That said, I'm not sure why a class D amp would be worse. I'd assume you'd actually want to power your transducers as efficiently as possible and that sound "quality" would be kind of pointless (e.g. D would actually make more sense than A/B). There are plenty of people running transducers off Fosis and worse amps than this. I'd love to hear the theory behind that take if you happen to find where you read it.
Let me get this straight this post has been up most of the day and it doesn't have basic info like the price in it? Is this just not showing up on the mobile app??
Oh suuuure it will output 300 watts. Right before it bursts into flames because you'd have to overvolt the sh!t out of it to obtain those numbers. I'm sure it's great for bookshelf speakers and very efficient larger speakers though.
The included psu will not get there of course. Typical marketing wank. They generally are pretty good about telling you this in the listings/paper
work though. This thing rocks! Plenty of power for basically any reasonable setup. If you need more power then this you already know and probably have multiple thousands of dollars worth of amps.
Got this for 50 in June last year and it's powering a pair of large speakers in the basement. Great for powering the speakers and they get fairly loud with this amp.

I have seen good reviews, but it does always make me laugh when the advertised power is more than the draw of the amp. Maybe there is a fusion reactor or something inside? Audio has always been kind of silly like that.

One powers rear surrounds in a 7.3.4 system. One powers Zone 2 on my covered porch. They work great for the use case.
How do you connect to this unit from the main AVR to power rear surrounds? Bluetooth?
AVR pre-outs ----> this
