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.
If you've always done it like that, then it's probably wrong. (Henry Ford)
