<VV> Voltage reducer

[JVHRoberts at aol.com]

Build the circuit in this web link, and adjust to 9 volts. Get the 1.5 amp  
version of this regulator, and heat sink it, and you'll have 1.5 amps of clean 
9  volt power.

Here is  my plan.

I have a Sirius Radio with a headphone jack.

I have  several sets of computer speakers.  One that has a 9volt power  
supply.  I want to cobble together a power plug to connect into the  fuse 
panel, and provide 9 volt power for the speakers.

Its been a  while since basic electronics back in high school.
