Problema nu e numai ca becul este la 12V ! Mai trebuie sa si calculezi(nimeresti) puterea becului. Daca-l pui de putere prea mica, o sa-ti limiteze amplitudinea inaltelor inaine de "soroc" ! daca-l pui de putere prea mare, o sa limiteze in timp ce se arde tweeterul, sau dupa. :smt005 Apropos : stie cineva de unde se poate cumpara sarma de 1 - 1,2 pentru bobine de filtre ?Don Mario
