Default doubt with inverter 12 to 24 5A

hello I wonder if it is possible to use this source Universal Notebook
tda in 7293/7294 because it has a 12v input and output 12v to 24v @ 5A
120w total however it has no outputs makes it possible to be symmetrical the current would be enough to feed those tda 7293/7294

I intend to build an automotive amplifier with 4 channels and found these great prices here inverters cheaper than building a

thanks for attention

Use a chipamp that was designed for car audio. With a BTL amp you get the same or even more output power from 12 V that you get with a TDA7293 from a 24 V single supply.
Examples are TDA1557 (2x17W@4Ohm@0,5% THD), TDA1560 (1x30W@4Ohm@0,5% THD), TDA1562 (1x55W@4Ohm@0,5% THD), TDA7386 (4x18W@4Ohm@0,8% THD), TDA7560 (4X19W@4Ohm@1% THD), TDA8560 (4x25W@4Ohm@0,5% THD).

Your alternative is to use two of those converters, if it is possible to connect the outputs in series and create a 24 V supply.

And please don't use that translator. Even if your English is not good, it will always be better than that.
