Has anyone tried building a 8 channel amp based off the TPA3116 amp? I built an active WTMW speaker, and it would be nice to not use 4 separate stereo amps and 4 power supplies for the pair.
EDIT: Oh oops I forgot this is diyAudio. I don't have any electronics skills, so I'm looking for a boxed solution I can buy.

Somehow came across this.
5 1 TPA3116 Digital Amplifier Board 6 Channel Amp Board 50W 4 100W 2 | eBay
This is the perfect configuration that I needed, 4 x 50W for the MT pair, and 2 x 100W for the 2 woofers wired in parallel.
The only thing I wish it had is 6 RCA inputs.
How does this work? Wouldn't I need 8 power supplies in this case?

Case, PSU, input and speaker output wiring is all DIY anyway, so why worry about RCAs. Without them board mounted you have freedom to mount them anywhere and run cable to the BFO JST connector. Same with the speaker outputs too. Arguably, you'd demount the green terminals and solder direct. Though I haven't on my dual chip.
Regards the "8xmono" idea.... In theory one big PSU will do. Though some have reported issues when running many amps off one PSU.
What kind of problems do people report with one big PSU? Seems like in theory it would work.
This in particular caught my eye.... In theory multiple chips are supposed to be synced Master/slave etc. If they come up chaotically, maybe they don't settle down.

You must make one as master and the rest as slaves. It will work anyhow, but you will get strange noise and bass anomalies (beating).
Buying a Chinese 5.1 card is no guarantee they have configured it correctly and the noise and bass interruption may be there.
Soldering is easy. Take some time to learn. It is something you will always use and something to add to your CV
