Will build my own transformer for the amp.

For those who want to break a wall at home with car sub hehehe, dream can come true. My teacher will give me the material to roll a big @ss transformer with 4 diodes, selectable output voltage one 12V other 13.8 for bit less amperage. 120V 60hz input, 100amp @ 12V output. 87amp@13.8volt or I can add another level output like 14.5 or so. Im tired to find PSU to test car amps. Not regulated output yet, but maybe in future.

well I would assume you are going to wind the wire around a collection of EI laminations but there are other options...

in this case an air core is probably a bad choice

metal core = less windings
air core = more winding
