how do I connect a car stereo without rca jack to a amp with rca jack?

[Doc]

my car has a receiver connected to an amp with rca jack. I want to connect another receiver without rca output to the amp buy using the speaker wires spliced to a rca jack. Will this work since the speaker wires is not a line out and the signal from the speaker wire is amplified

I had a friend actually brought the RCA connection cable and cut them to bare wire and connected to the wire behind the car stereo it worked good, or you can use a fm modulator, but this will not give you a clean sound quality all that, still works.

also most of the RCA Jack is made of speaker wire, if you know what your doing you could just make one your self, radio shake is the place you want to go and pick things up from there make everything your own. Be-sure to twisted the wires together to make a stronger connection. Good luck.

Just tap into the rear speakers for the RCA signal. Good luck!
