I saw a thread where people were asking how they could make their Car Amp work in their home, I found where someone had managed to make one work with a PSU from a computer. People wanted a tutorial on how to do it, so I played with the idea and came up with this. I am NOT responsible if you blow something up, or if you start a fire, but This is a fairly safe project. Use a standard computer PSU, no internal modification required, remember if you open a PSU, there are parts in there that WILL shock you, even un-plugged. I cut one of the molex connectors off of the PSU, but there are ways to do this without damaging the psu. On higher power PSUs there are more than one rail inside the psu for power, each providing only part of the rated wattage, so, I made sure I hooked both strands of molex connectors to the amp because I know that it will draw from both rails. Some PSUs may have more. Just common sense tells me DO NOT HOOK UP MORE WATTAGE TO THE AMP THAN YOUR PSU CAN PROVIDE! and remember that the amp itself wastes some power for the LEDs and about 30 percent in heat, so, dont connect 650w of speakers with a 650w psu. I would stay below 400w on the speakers. I dont know much about these car amps, I usually deal with DJ audio/home theater equipment, so make sure you know what speaker impedance is, and how to figure it, and make sure you dont under power the speakers Hope the video helps! feel free to email me with questions/requests at SARGENTSCRUFY@gmail.com
