Sorry newbie question. I am looking at purchasing amp innards.
In the link below, the power supply and channel modules are clearly evident.

This is a two channel class D amp, but I'm looking at putting together a one channel sub amp based on the innards of this one.
Am I able to simply use one channel module or is the power supply designed to only run with two channel boards connected?
Cheers

This is one for the Class D forum, suggest you report your post (hit the little triangle on the left, below your post) and ask them to shift it there.
in most cases, a class D amplifier is bridged. Parallel or sequential connection of channels is not provided. In mono, you can only use one channel. You can also switch on a separate speaker for each channel, and send a mono signal to the inputs.
As an experiment, you could use a transformer with separate input and common speaker windings. You can try parallel connection of channels to a common load with filter coils on each output line. And you need to identify the in-phase lines. Out-of-phase switching will damage the amplifier like a short circuit.
I have not tried it and I am not responsible for the consequences! 🙁

Not sure if there's a misunderstanding here.
Im not trying to connect more channels in parallel or sequential.
I'm doing the opposite, getting rid of one channel in a 2CH class D amp to make a 1CH class D amp.
Is this achievable or is a switch mode power supply designed to be specific to how many channels it is driving?
Most SMPS are either constant voltage, or in case of LED, constant current.
Using it at half load has a margin of safety, Chinese stuff may not be best quality.
Buy the board and a good SMPS - Meanwell is good - many others too - separately.

Thread moved as requested.You can use one channel (any of your choice). An unused channel can be loaded with a 100 ohm\ 1W resistor.
Ok so all I need to do is connect the power supply output of one of the channels with an arbitrary resistor?
