Hooking up a car amp to a house application

[Ku-sama]

I want to temporarily hook up a car amp to my house power...

things I think I'll need...

1: amp

2: speakers

3: Wires

4: Computer Power Supply

do I just tap into the yellow 12V wire and hook the ground up to the black wire on the same rail?

Most computer power supplies won't provide enough current to power an amp.

And in most cases a 12v power supply that is capable of providing the amount of amperage you'd want to run an automotive amplifier in your house is going to be a bit pricey.

I paid $100 for my 35a power supply and $155 for my 50a //content.invisioncic.com/y282845/emoticons/fyi.gif.9f1f679348da7204ce960cfc74bca8e0.gif and neither of those has near enough Oomph to run a big monoblock at full tilt. They're big enough for testing purposes to verify functionality but you wouldn't want to try and really wang on 'em or (best case) the overdraw protections would kick in or (worst case) the power supply would burn up trying to provide an amount of current it simply isn't capable of making.

well, the PSU I have hooded up had dual 12V rails, totaling 58A. $45

my PC's power supply had three rails, totaling in 83A $89

besides, it's enough juice to make the Crunch amp wang pretty harg

I'm interested to see how this turns out for you...I have a bunch of power supplies kicking around....

 

[Ku-sama]

AFAIK, you can strap the power supplies, as long as they are identical...

I don't really know but, don't you need DC to run an amp? And your house puts out AC, right?

 

[talon2nr7588 10+ year member]

can you get a whole bunch of [power supplies and strap em?

computers run off of DC, the power supply converts the power....

dunno, I think you can with similar ones, but I have no idea...

It works...

Thanks to Req for the help out on this...

I was surprised what I got out of this old school alpine amp. only 60 watts rms but it cleaned the dust off the cheezy pyle speaker...also tested it on a jl12w0...not bad for what it was...I think I'm going to try wiring two in parallel now since these are only 100 watts a piece.

i have an amp just like that but more square than rectangle and its 60x2 rms
