Where's the cheapest place to get an FM modulator for an Alpine cd changer?

 

Which changer do you have? http://www.google.com search there

 

ebay.com

 

I take it that you have a 93 civic ex. if it has CD changer controls, you can connect the M-bus Alpine CD changer to yoru factory headunit, by either using a $20.00 adapter or simply spicing a M-bus and swithching the red wire with the black one.
