I just recently took out my system b/c i was gunna sell my car but decided to keep it so i put the system back in. I wired everything correctly like it was before now when i change the source to AUX or CD amp doesnt turn on but when I change it to AM/FM Radio it turns on. What did I do wrong???
you have the REM wire from the amp hooked to the ANT (antenna) wire on the back of the HU instead of the REM output on the back of the HU. both are blue, one has a white stripe, easy to mix them up. swap the wire and you should be good to go.
