Deck doesnt remember settings..?

Question

On the back of my deck I couldnt get it to work and an installer told me i would have to put the red wire with both yellow wires in order for the deck to work. Maybe it was a yellow cord with both reds. Not sure. But now everytime I turn the deck on I have to redo my bass settings treble mids etc... Basically the harness is missing either a red cord or a yellow one and there are no harnesses that are any diff so what do i do??

Answer 1

Yellow wire must be connected to a Battery connection at the fuse box. It is loosing your settings when you turn car off like completely unplugging stereo. Red should be connected to switched power so only when key is on will it work.
