    Have you got a 12v switched running to the amp as well, so it turns on/off with the ignition?

    Hello

    i think you forgot to connect a remote lead from the back of you head unit to the Amp .... so that when you turn the head unit on that remote lead feeds a signal to the amp ....

    REMOTE LEAD ! if you do not have one on the back of the stereo marked specificaly for as AMP REMOTE or somfink like that .. then you may have a REMOVET Areial ..if you do not have that either then you may need to run another lead from the batter or elsewhere straight to your amp with a on off switch need the driver position !

    hope this helps .. KK

    As already stated you need to signal the amp to switch on, just having a supply to the amp won't power it up.
    As a temp measure to test it you can run a length of wire from the 'REM' terminal and bridge it onto the power cable (i.e. in parallel), don't leave this without a switch or disconnect it or you will have a discharged battery in the morning.

    buy a 12v test meter or bulb tester.

    FIRST TEST
    Run one side of tester to + cable ( red) other to - (black) do you have voltage?/light/reading?

    Switch headunit on and do the same again BUT THIS TIME RUN the red cable on the REM+ (the cable you connect to the back of the headunit to the rem+ or electrical arieal connection) this should not light up. Should light up

    please update your post and i will continue with the step by step.
