I bought an aftermarket head unit for my 2003 Mits Galant. I bought a Merta 70-7003 amplifier integration harness and thought I hooked it up properly. Got power but no sound. I have the RCA's hooked up properly but not sure if I have to do something with the blue/white (amplifier on)wire coming of the converter. Guy at Best Buy said I didn't need to. Please help, I only have a day to fix it before Christmas. Thanks.

Connect the blue/white on the din cable to the blue/white from the aftermarket radio.

How, just splice them? (I'm not that savvy to know) Thanks!

nononono... there is another harness for power ground switched and ant amplifier.  anyways just twist the two wires together and solder them.  then tape or crimp cap the connection to insulate it.
