ac to dc power supply, creation

I would like some simple directions on how to make a simple AC to DC power converter.


Originally I was using an old 1200 watt PC PowerSupply with 24amp rails hooked to a car amp which worked rather well. I had used the black and green wire and mended them together so the power switch turns the unit on and it stay on until I flip the switch off.  Then I took all the leads for each pc rail and cut them down, and put stand offs on them so I only used the ones I needed. I took ALL the 12v rails and soldered them together to a 8 gauge car power wire which went to the amplifiers positive lead, and all the ground/earth wires mended together to a 8 gauage power wire to the amps negative.  I had then used a smaller 12 gauge wire for the lead switch to the amps remote.  Turned it on, and other then not being able to use the amp to full potential (it would shut off from lack of power) it worked flawlessly, until today, I acidentally kicked the psu into the amp and it short circuited somehow (I believe it was the amps fault because I had problems with it before.)


So now I want to make my own AC to DC converter.  Something that would be capable of driving say a car amp that uses a 60amp fuse for protection (so power up to 60amps?). Not quite sure the technical side of all this, to be honest I fidled around and figured that psu stuff out on my own, randomly touching wires together which I know, isn't good, but hey, we all do stupid shit when were young.  I had this unit for over a few years, but instead of wasting money on a power supply for a pc, that really can't power what i need the way i want, I wanted to make my own simple power converter.


Any help, any diagrams, and any feedback is welcome . one website I saw guy made an AC to DC really simple but it didn't have enough power to drive what I'd use on it, and he used banana plug style connecters for the power ground and remote! Thanks in advance and p.s. I am a noob at electronics, honestly, I know what I know but even that isn't much to begin with


My dad has a series of books, I had asked him once if he could teach me how to build my own amplifier so I could drive this custom subwoofer box I made (its case is based on stage show bass boxes, the port gets bigger and bigger to allow the bass to really reverberate and become louder then it would be in a normal box) and he ended up telling me to read. That doesn't help me really, a simply diagram and parts list would be great not trying to be a dick but electronics are hard to learn through books, I learn better through instructions and tinkering.
