Default Custom computer stereo

Well, First, I was either looking at two of these

MLI-65
http://www.mach5audio.com/product_in...7171c76d02db5d

OR

MTX T4508-04
http://www.onlinecarstereo.com/CarAu...roductID=13307

OR
Kicker 07C8-4
http://www.onlinecarstereo.com/CarAu...roductID=17406


But here is the thing, I'm not sure how I would power these.

Also, how would I give it an audio signal.


Then, as for speakers, and power for them and a signal to them, I'm at a complete loss. I would like to keep this as cheap as possible. Help, lol

to get an audio signal you would use a splitters on the outputs of your sound card to convert the 1/8" jacks to 2 1/4" jacks a pecie (in total you will have 3 1/4" jacks if your going to run a 5.1 setup) (AKA composites). then you would need an amp (a home amp, not a car amp, big difference) like one of these

as for the speakers there just like regular car speakers, just there in a small box.

googled home audio speakers, they look like a good company

EDIT:
here is the splitter your looking for, go down to a radio shack and you can buy them there, youll need 3 of them for a 5.1 setup

I know all about that, In fact I was running a Sony 600x6 Home Theater amp on a pair of Bose Bookshelf speakers for a few months.

But I wanted to change it up, and get the following (after the last two hours of research i found what i want speaker wise)

2x

2x

And I still cant decided about the subwoofer.

I found the amp I want too!

Lol, but for 1/10th that price. I cant find a cheap amp to suit my needs, idk what to do.. hmm.

im no expert but is it possible to have both 4ohm and 8ohm speakers on the same amp? or is that just the same channel?

heres a good amp i found
http://www.monitoroutlet.com/product...g510,2807.html
it will power those speakers you posted, although having some 8ohm speakers might cause a little bit of problems, but im not sure.

Its all in the wiring, you can wire the speakers down to 4 ohms.

I think at least, not completely sure.

Anyways, thats still a home audio receiver, i'm looking for more of a push button on, and a much more compact design. Because those you turn it on and you gotta wait for the channels to load and what not.

I want instant, and smaller. Just like when you turn on a computer speaker, you don't have to wait at all.

just keep it on all the time, thats what i do with mine, there are mute buttons or you can turn the volume all the way down.

buy a cheap car amp maybe. you could also even get a cheap car stereo with some good wattage that has an input on it if you wanted to go really compact. maybe you could hook up a car amp to your computers PSU, dont car stereo's run off 12v?

Yeah, but thats the thing, I dont know exactly how to splice it in.

Hmm, do you still have that psu for sale or was that someone else? That might be a fun project if I could find a cheap enough amp, lol.

Although also inputting the signal would be tough. Hmm

Careful with the impedance and how you wire up speakers.

Try and use the same impedance on all the channels with the amp if the amp employs a single power supply. If the amp has completely separate power supplies for the amps then use what you want just keep some kind of symmetry. Also keep cable lengths the same for left and right channels.

make sure you run at or about the required impedance on each channel. lower impedance and well.. fry things.
