Is there a way I can power a car amplifier through a computer power supply? I could care less about if i fry one of them because I can get a psu for free and the amp Is a piece of crap one that I don't care what happens to it. I found this http://www.wikihow.com/Convert-a-Computer-ATX-Power-Supply-to-a-Lab-Power-Supply Im wondering if all i have to do is bundle all the yellow (12v+) and all the black (ground) and wala i can power a amplifier. I will fuse the 12+ or just 1 yellow to the power and remote and one black to the ground? I also found this. http://forum.ecoustics.com/bbs/messages/4/17571.html
You can power up and run a small amp with one I am sure.... But to run an amp that has any serious current draw, look to using power supply and an battery....this will give much better results. The computer PS is 12 volt, and thats it, no higher than 12 volt, period...most amps see about 13-14 volts in the car when it is unning.. I have succesfully run 2 orion amps at the house off of a 50 amp power supply and a couple of car batteries....they performed rather well for a few hours till the RMS voltage was dipping below 12.5 volts.... Now, parrellel several computer PS's..that might do a rather nice job! All though they will never do more than 12 volts.
yes, i've done it a few times as it's hard to find 12 volt adapters that are over 1 amp of output. You should have a car battery if you want it to pump but adapters and pc power supplies will work, just don't turn it up at all or the power supply will go kaput. I do it for testing small amps before i sell to ebay and am too lazy to go out to my car and try them there.
lol I do have all that stuff. but I don't think the amp will last very long. its just a old jensen 600w max 75w rms. Its like a 6 channel amp.
battery chargers cannot recharge fast enough...caps are a waste because the electrical power of the battery and charger are not strong enough to power the cap also...AND caps don't do anything for a weak electrical system. There are many many manufacturers that make power supplies out there...I have a 25 amp power supply from radioshack...its nothing heavy duty but does the job...puts out 13.8 volts that 12 volt pc power supply will do NOTHING to power an amp unless the battery that is paired with it dips below 12 volts
You want a power supply? Get this one http://newyork.craigslist.org/brk/ele/316365084.html This will do some SERIOUS output........Will even start a car without a battery!!!!! Ya no shyte.....
