Hello there, ı was finished tests about this. best works with at home or car. The original circuit's editing more power less impedance and less to carry. ı was put 2x70vdc and ı get 2x400w with this. ıt have a phase inverter and stereo mode. check this out and feel the power. it stands stable 2 ohms ;) the files are at the attachments...

You can make DC TO DC converter for use at the cars. you have 2 ways to make, you can use ATX pc power supply's cores without re-winding or you can wind toroidal transformer easily you can choose anyone. MY friends made succesfully, If you want i'll publish at here but ı want more interests other members.

You can put up to 2x70v, but you can put about 2x50 60v. it is already a car amplifier and good works car smps's but it must 800w or above. I'll post some car smps circuit to this.

sure you can check this one, ı find one about 500w for 12vdc however, no winding required! if you find ei33 core, you can done. ei33 core in the atx power supplies. you can dismount and mount this circuit non problem.
