Anyone ever setup a 3 bass amp configuration?

And I will try the small mixer into one amp
Which is what I do with two signals - Y Splitter at the beginning and a DI inbetween pedalboard and amp...Looks messy but works great........adding a third would replace the Y with another small mixer

Thanks everyone for responding. All great suggestions. And I will try the small mixer into one amp but my concern is the 3 different signals in to one amp will drive the cabinet harder and will not articulate the tone I’m looking for. Using different amps will separate the audio better and sound cleaner.
No.
The purpose of the mixer is to mix the 3 signals and to adjust the output level of the mixed signals to the amp.
