DC 12-15V to AC 10.5V are there such low power inverters?

There is an idea to shove PC-multimedia speakers into the car, as a radio. Their transformer gives out 10.5V 2A, I looked for Ali - there is either DC-DC, or DC-AC 12V to 220V. Are there DC-AC converters with adjustable output voltage on sale?

Most likely in the column immediately after the transformer there is a diode bridge. It will be easiest to check by disassembling.
Next, to choose from, measure the voltage after it and connect the desired dc-dc power supply there. Or just connect the corresponding dc power supply to the input instead of the transformer.

And what religion does not allow you to throw out the transformer and take a DC / DC converter from 12-18V to 10.5?
This is not to mention the fact that this idea is not a fountain at all. 10.5V at 2A is a maximum of 20W of power. Taking into account the losses and efficiency of the amplifier - a maximum of 10W per speaker. It will be possible to listen only in the parking lot with the engine turned off.
