How Do I Hook an amp up @ home?

[LoggedOut 10+ year member]

Since most of you guys practically wrote the book on installs, and im a n0ob, i was hoping youse guys could give a young'n some advice as to how to hook an amp/sub up to a standard 110v wall socket, if there is a way. I want to be able to do this for multiple reasons, one being to be able to test shit without having to be outside in the dead of winter and moving all my shit around in my trunk, and also so i can hook an amped sub up to my home audio speakers. is this shit even possible? to convert 110v to 12v? my dad's a musician and my brothers an electrical engineer, but i figured id try you guys, because neither of them know much about CAR audio. help a nugga out? i see all these videos of people blowing their subs up plugged into a 220v socket, and i feel like if i tried to do something like that i'd either burn my house down or light my face on fire. anyone got any suggestions for the kid?

Either snag a computer power supply or a standard 12v supply. What kind of equipment are you hooking up? Anything over 500 watts won't be cost affective to run at home.

Just an older w3 and a 400w amp. which most likely won't be @ max gain. i just want to be able to play around or test shit inside. why not cost effective? too much electricity?

get a comp powersupply with a rating of 25amps or more on the 12v rail

one yellow to pos, 1 yellow to rem, and 1 black to ground.

or do like i do and bunch all the black to ground and all the yellow except one to pos

You could try to find a car battery charger that can put out upwards of 30 amps & ghetto rig it, but that could be expensive & potentionally dangerous if wires are exposed.

pawn shop and computer store, just buy the cheapest.

I'm running a 22a psu on a clarion 400 watt rms amp, never shut down or any other problem with that

it slam a lot, ask the dog upstair //content.invisioncic.com/y282845/emoticons/biggrin.gif.d71a5d36fcbab170f2364c9f2e3946cb.gif

yeah yellow on +12v , black on ground and jump the 12v on the remote, in my case the 5v didnt work

So then would you just use an rca to 3.5mm to hook it up to say your comp and then it would work? You dont need to ground it anywhere at home?

you got it right!

the only neg is the ventilator noise, i'm sure you'll live with it

60 Amps on a single 12V rail on that power supply, I'm looking around to see if I find any more though.

If I am doing this properly, that is only 720w @ 100% effeciency...which is not much. Hopefully my math is wrong, as I'd like to be able to hook up 12v amp in home as well.

Home audio amps are too expensive.
