Simple. Get a PSU with a great amp rating for your amplifier using the four pronged connecter (see picture) mostly used for older CD players inside a computer, cut the red wire (+) the black (gnd) and then cut the second black wire so that you have a 2" long wire by itself Red wire obviously goes into your power input Black into the ground now with the 2" wire you cut, bridge the positive input with the RMT (remote) input on your car amp your car amp turns on when it gets a jump off of a car battery so when you turn on your PSU it thinks its hooked up into a car and activates thats about it MAKE SURE: wrap open end wires with electrical tape Also, I just read that the yellow wire provides more voltage but im not sure. I've done this before and it worked out fine I just can't re-find the article, so bitch at me if you need it because I know my instructions here aren't that thorough
