    Hey guys I just got my sub amp and headunit hooked up but the amp is not turning on the headunit works perfectly. Am I supposed to turn the amp on manually or is it supposed to automaticly turn on with the headunit? Its an alpine 450

    you have to run a turn on wire from the headunit to the amp... then it will turn on automatically- it's sometimes labeled amp or power antenna on the back of the headunit

    first step is to get a volt meter and make sure the power wire is hot and you are getting some small voltage from the turn on wire... if not then start checking fuses

    I did still nothing

    How do I know if the fuse is bad? I connected the positive terminal while the key was in the on position could I have blown the fuse through this?

    you get a meter as someone already suggested and start checking to see where you have power. You could have a bad fuse, even if it does not look blown. It can separate at the end where you cannot see it.
