Is there any possible way to power car speakers in a home? off the 110V plug, what adapters are needed and where can i find these? i am planning on making a fiberglass box for the corners of my room to add an extra touch and wondering if there is any way to use car speakers?
Speakers are passive devices meaning they have no need for line power. I assume you mean you wish to power an automotive amplifier from the AC mains. Figure out how much current you need at 12 volts and we can go from there.

Probably you have already powered your amplifier or stereo from the mains line. There is no need to power the speakers as they get their power from the amplifier.
You can use car speakers instead of "real" loudspeakers as long as the Ohms value is correct. This value is usually denoted on the back of your amplifier. For example, if your amplifier states it needs "4-8 Ohms" loudspeakers, you can connect car loudspeakers that are in between 4 and 8 Ohms in value.
You should be aware, though, that car loudspeakers are designed for cars where the ambient noise is usually high. They are designed to sound louder in frequency ranges where cars generate a lot of noise. That means, you will not get a "Hi-Fi" audio experience from them in a different setting such as a quiet home environment. Car speakers are usually "broad-band" as well, meaning, they will emit sound, but with significant differences between high, low and average tones.
For a good sound experience I recommend that you use or build "normal" loudspeaker boxes. If you don't care about the sound quality, you can get along with car speakers.

Im guessing probably 1000 watts what parts would i need?
Actually the stock 6x9 speakers from later model GM cars are 10 ohm speakers and make quite good in wall/ceiling speakers for a low price. (though certainly not for a 100+ watt stereo system)

110V
Take a high school physics class, or if you are a college age kid, take a physics class.
>110V
Sounds like you haven't a real feel for what I'm trying to get from you... read the amplifiers specifications and find out how much CURRENT (measured in AMPS) it requires at full load in order for it to produce your desired 1000 watts of POWER output. If more than one device is to be powered, add these onto the total.
Power supplies can be of the switching variety like your computer uses. This might not be suitable for automotive audio systems. There are also analog designs for a power supplies. Low current power supplies of this type can be easily built. Designs for as much as 20 amps are available however, here is one that can be had at less cost than what the parts would cost:
well i have not purchased an amplifier yet nor have i purchased speakers im just trying to find a general cost for something of this sort, thank you for the info it is greatly appreciated
connect them to loudspeaker terminals of some suitable appliance.
Bye. Jasen

Gee, that sure would be easier if there was some kind of something on the internet where you could just type in what you wanted and it would go searching databases compiled from information gleaned from crawling web sites. Boy, if somebody came up with something like that it sure would be handy! Probably make a lot of money, too!!
My Googleness! You are a visionary!
Just go buy a home tuner/amplifier and drive your car speakers. Speakers is speakers.

Then where is the point to all this?
There is no advantage to buying car speakers for this project. If you had some on hand, or even if you got some cheap at a garage sale, obviously the lack of cost would be a factor. But since you don't have them, that advantage goes out the window.
What you may have missed is that you can get raw speakers that aren't made for cars. SOmething has to go in the boxes that you can buy at the stereo store. You may see raw car speakers in more obvious places because in a lot of cases, car speakers are mounted behind panels in the car, so the raw speakers are wanted and work. Use them at home, and you need to mount them in something, so home speakers usually come in the form of a box. But you can get raw speakers intended for putting in boxes just like you can find car speakers, and those will likely be better than those intended for cars.
Take note that for "good sound" it's not just a matter of putting the speakers in a box, the box has to fit the speakers and be built not to rattle and so on. This is one of the limitations of speakers in cars, they are basically just mounted behind panels and hope for the best.

You're welcome.
The only reason i was considering doing car speakers is because i wanna make a fiberglass box to put under my desk and mold it around the corner of my wall for just a neat effect and did not know that you could buy home speakers without the speaker boxes. thanks again everyone for the info!
If you are going to build the speaker enclosure, the best material is MDF (medium density fiberboard). 3/4 inch is good. This is ugly stuff, but it's excellent for speaker enclosures because it is "dead" compared to (say) plywood). (And a lot cheaper!) You don't want enclosure resonances mucking up your sound. You can then put your fiberglass over the MDF, but be wary of any thin panels that might vibrate. Maybe you could build a regular MDF box for the speaker, then add little MDF shapes to make a form that will support the fiberglass.
Note that speaker box design is for woofers and subwoofers. Tweeters typically have enclosed backs so you can just mount them in the same box. Midrange drivers often have enclosed backs, but if they don't you need to isolate them from the woofer airspace, or the low frequency woofer pressure waves will cause the midrange to produce frequency modulation as it gets pushed about.... bad stuff.
If ultimate high fidelity is not the main goal here, there may be some virtue to car speakers, since they are often coaxial "all in one" units with a little tweeter nestled in front of a midrange/woofer.
Note, however, that home sound will rarely be able to approach the deep bass possible with even a small trunk-mounted car speaker. The reason is that in a car, you are essentially inside a pressure chamber: The frequency response can go right down to DC if the chamber is sealed. (Of course, breathing gets a bit difficult... but people should be willing to make *some* sacrifices for good sound!)
So you may find that for home use you will want bigger woofers (and hence bigger enclosures) than most cars have.
