Home amp

I have a 150watt car amp that I am wanting to use in my house for a sub. I ned to know how to get 120volts AC to 12-14 volts DC, at about 10-20 amps. All of the DC converters i have like for cordless phones ansd such are only about 12volts DC @ 1amp.

Thanks

yea you want to be looking for a "dc power supply".  I do know that radioshack has on their web site power supplies rated for something like 15 or 20 amps, for right around $100.

What kind of sub are you using?  Is it a car sub?  What's the impedance?  You might be better off getting a standalone monoblock amp made for home use, if your sub is 8 or 6ohms, but then again some home amps can handle 4 or 2 ohm loads as well.  Just make sure you don't fry the amp

You might have better luck at Jameco or I think it is "newark electronics" not sure though,  they both sell different sorts of power supplies, you will need a bit more than just a standard wall plug ac/dc converter, probably will need higher amp rating too, but then again I am not sure exactly what you are looking for, please let us know all the specs!. 

Radioshack is generally more expensive for components and such, but hey when in doubt BUILD YOUR OWN!!! ;)
