Has anyone got any plans for a car amp?
hi, i was just wondering if anyone has got any plans for a car amp, the amp would need high level input and able to produce enough power to run two 12" subs. (the subs are 8ohms, but i can run them in series).
thanks |

finding an amp isnt the hard part, its building the SMPS.
12V will never produce more than 10W or so, no matter how much amperage. So, you need a SMPS that can convert 12V to +/- 30 or so. I happen to be working on a car amp right now, using this schematic: http://sound.westhost.com/project89.htm i am going to be using the simplified schematic at the bottom of the page. |
