Hi..
One of my friends wants me to build him a 2.1 amp which is supposed to power from a 12V Car battery, thus the problem is i want to use tda2030a ICs (4 OF THEM<<2 for sub.wf) and it requires a DUAL POWERSUPPLY!!! so the real question is how can i get dual powersupply from that single supply battery? Any ideas/circuits?
