Default 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:

i am going to be using the simplified schematic at the bottom of the page.
