Car speakers?

Here's a quick lesson:
Speakers are big magnets attached to a cone (that lets it move) that is surrounded by a coil of wire (voice coil). Applying a current through the coil will make it attract or repel the magnet. Run a wave that alternates at a given frequency and the magnet will moved at that frequency. Moving the magnet stretches the cone surface which moves air creating sound waves that you hear.
You computer sound card puts out a reference signal which is the signal needed to drive the speaker to make sound. This signal is low voltage and not strong enough to produce very much sound at all. This is done to keep power requirements down on the card. This reference signal is fed into an amp (located in the sub for computer speakers, in HT recievers or can be seperate, like in high end car audio). The amp takes that reference signal, boosts the power and then sends that signal out to the speakers. You have to amplify one signal at a time, so for 2 channel stereo, you either need 2 amps or one 2 channel amp.
You have a sound card that puts out a reference signal (low power) you have car speakers that require amped power (power rating should be on box and back of speaker). You need a way to increase the power of the reference signal to the power required by the speakers.
Now I'm assuming these are midrange speakers. If they are high end tweeters or a sub then you will want a cross over which will limit the frequencies passed to the speakers so you aren't trying to play stuff that is out of range of the speakers.

They're pretty nice speakers, they're made by Crunch USA, and it's like the Blackmaxx High Performance Series or something of that sort, two five-inch coax speakers.
Impedance- 4 Ohms
Frequency Response- 55Hz-20Khz
Sensitivity- 86dB
Mounting Depth- 2.4"
RMS/ Peak- 60/120 Watts
Not exactly sure what all this means, but it was in the manual, i hope these were the stats you were looking for! lol

Just go buy some small boxes (about $30) and 65(ish) Watt RMS x2 @ 4 ohm amp (around $100). If you go to a good audio store and tell them what speakers you have and show them the specs they can recomend which amps to look at. It will be more pricey then a pair of computer speakers, but sound quality should be much better

I need someone who's good with speakers and amps and just all that jazz to answer me this, what kind of an amp do i need?
b/c i can't use a car speaker amp b/c that runs to a battery which i don't have in my room. I happen to have a 200 watt amp that my band occasionally uses to power our 16 mixing board and 2x10 custom speakers. Is there any way i could use this equipment as my computer speaker set up? Please give me an answer before i go out and spend unneccesary money on way over-priced computer speakers. Thanks in advance.

Sorry, i've been slacking. The amp just has to be a 2 channel amp. You have a left and right channel for stereo sound. One speaker per channel.
You can hook up the amp to your computer with a mini-jack to RCA adaptor that you can find at walmart or target for a few bucks. It converts the headphone style jack that your sound card has to the RCA plugs your amp should have. The 200 amp could work, but it might be a little too powerfull, so you'd have to keep the gain turned down. It would work like this, but sound quality would suffer. Just make sure your amp is rated at 4 ohms per channel.
