Da, dar cu cateva modificari majore. Adica sa-i faci o sursa in comutatie care din 12 V sa faca +- 20- V.

am un tranzistor de 25v pe el daca il anulez poate porni?sau sa il schimb cu unul de 16v 470uf

Cu TDA2040 nu merita sa faci amplificator pentru masina.Asta merge bine alimentat diferential(merge si alimentat normal dar nu faci mare branza cu el) si te complici.Nici puterea nu este asa de mare.Mai bine alegi alt circuit cu care sa faci asta.

imi poti spune cu ce circuit il pot inlocuii?
