but the man say identical ps
how the wires different?

forgot I made this thread oui , yea Pioneer it worked perfectly, thanks everyone

ran this thing for hours and it handles the pressure with ease, the middle PSU in this pic failed the other day and started giving out 18V

swapped it out with another spare I had and it runs nicely.
Also took out the piece of metal with the holes in it where all the 6AWG wires lead to and made a neat little distribution block from an old Air Condition breaker

only bad thing is that the max voltage is 11.8 when the amp is connected with no music playing and gets as low as 10V when trying to play at high volume.

Added a relay because I was bored

the orange cylinders are an array of capacitors adding up to 0.03F, good enuff for a 30W amp

Planning to upgrade the PSUs and hack the circuit for the 16 pin IC to increase the voltage of the 12V rail, and I'll try to do it neater this time

wtf? jed why didnt you just buy a 12v. 10 amp psu?
Those arent designed for constant peak load and will always fail after a while. after a few more swaps ull regret this choice. and you WILL get fedup of those wires. trust me.

The only reason the middle one failed is because it was meant to be thrown away in the first place. I just changed the swollen capacitor and ignored the fact the board was already scorched

I intend to start a new build from scratch to eliminate the bird's nest of wires

and where sells 12V 10A PSU cheap? I don't mind using that once the price is right

montrose electronics.
or if you wanna go the fun way, they also have transformers. use one big enough with a bridge rectifier ( or use 4 diodes if ur that bored) and a capacitor to smoothen out the dc. it'll be cheaper than the unit and still satisfy whatever tech crave u havin. even cheaper if you find an old ups and use the tran from it.

nice, thanks yo

Now u implant the idea of making a giant PSU with multiple transformers and rectifiers, I not gonna sleep now

Wow! The only think missing is the Flux Capacitor! :faint:

what a pretty fire hazard

I hope he have no young children in that place otherwise it's snap, crackle & pop! Barbecued babies.

i glad you get thru...hope you run some fuses in that ratch tho

me personally get enuff shock/fires thru my own shitty engineering to continue down that path... (there is a reason my work space floor is terazzo)

you know you can get 12v, 20a/20a/30a/30a parallel in ONE 1000w psu right?
