How to make a home stereo in old antique radio with a car stereo?
I have an old vintage radio that stands about 4 ft tall. I want to take out the old tube radio and replace with car radio and two new speakers. Also possibly a sub woofer and amp will be placed in it.. Any guidance on how to convert the car stereo to run all this on an 12v outlet plug. Also can I put my 12 '' sub woofer and 600 w amp in it and still sound good.... Answer me thanks 
sounds like an interesting project…
BUT FIRST, make sure that you are not destoying a valuable item. Some antique radios are valuable!
Next, assemble your parts. Lay them out as you would in a car.
Buy a very good power supply. Youneed a power supply that does not generate electronic noise. I would highly recommend the Astron power supplies.
Next determin the size of power supply needed.
I like http://www.gigaparts.com for the power supply.
