I'd like to drive each driver in my active 3-way speakers with an individual amp channel, preferably TPA3255.
So I could go for a 2-channel amp plus a single channel amp.
Or another option - I found this board:
Amplifier Board - AIYIMA B2D2205 - TPA3255 | 4 Channel 315W Power Ampl
A 4 channel TPA3255 amp.
I remember reading though that TPA's don't do well when an output isn't connected (?).
Would it be okay to use a 4 channel board like this for 3 channels, leaving one unconnected? Or would that cause problems?
Any other tips / hints on getting 3 TPA3255 channels working would be greatly appreciated as well.

Doing something similar
Hi, I'm doing something very similar - building active version of Troels Gravesen's Bookshelf-3WC design. The TPA3255 is overkill for these though. For testing them I am going to use a second-hand 7.1 AV receiver in direct mode. Once they are working I will look at trying to make chip-based amps. I just don't know how much watts I really need!
I will keep an eye on your project with much interest!
