SOURCE: wiring car amp up
the rem wire is for switched power from your head unit usually most after market stereos(head units) have an output for the rem wire.......if not use the power antenna wire from the back of the radio (usually blue or blue white) as for the input you need to use one or the other low or phono
Hope this helps..Good Luck!

This one Wire should be for the +. Try connecting the + to the Head Unit and - to a Common Ground. At the Worst, You will Blow the Amp Fuse if not Correct. The Lead from the Head Unit is Only an Off and On from the Ignition. Please Rate My Response! Thanks!
