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)
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.

These are great amps for 60 bucks, for something like desktop listening or a situation where you don't need a remote for power or volume. Though I have had a PSU failure on one of my two (which they replaced for free)
What brand and model towers? Your speakers will have a nominal impedance rating and a power rating. If your speakers are rated at 8 ohms and recommended power is 15w to 100w, this amp will drive them to 50% of their rating, as it puts out 48 watts per channel (per speaker).

I second that these devices can't handle pushing 300 watts at 4 ohms. I'd expect my vega re38s or klipsch rf7s to burn this thing up if I attempted it.

I'm using a WIIM streamer connected to amps like this. Pandora, Spotify, airplay, and just about anything else you would need.
Thank you for the reminder! What's really stupid is that I bought two other Pioneer surround amps in the intervening years, primarily because they were black and not silver, and both of the Pioneers have since failed.
Can someone here recommend a few good transducers and amps for this purpose? Thanks in advance.
