Go to radioshack and get a 12V AC Adapter... cut off the connector and splice the wires for power and ground together... also splice the speakerwires to whatever home stereo system you want......

the only thing I'm not sure about is amperage... I don' t know how much current household wiring can hold.  Also, the Radioshack adapters tend to have small amperage loads... I think the one I have is about .5A... you may have to find a heavy duty one.

I hope this helps... it sounds like it could be a creative project.

Radioshack sells 12v  power supplies ranging from .01 A up to like 20 A. Find one that work for you.

When I first started installing, my house stereo was a car stereo, powered with a 7-band eq-amp combo. There are several ways you can power your setup. The best is a filtered power supply like they use in car audio display racks you see in the stores. These are specifically designed for this purpose. But they are not cheap! ($100+). Just remember your "power formula" for deciding how much amperage you need. Use the chart at: https://www.the12volt.com/ohm/page2.asp to calculate for "Current. Using the maximum power output of your stereo (or amplifier if you have a backstrapped unit on a portable boombox that unplugs). WARNING!! If you are using home speakers connected to your head unit or amp, be very careful! Home speakers are generally rated at 4 ohms, as opposed to autosound speakers, which are 8 ohms! This could cause your  amp/stereo to overheat, causing it to clip.. Watch the volume levels. As long as you don't hear any detectable distortion on heavy bass notes, you should be OK.
