    Blue cable?

    My carputer plans are progressing slowly due to finance but in the mean time i want to run my car audio system from my mp3 player....

    Can i just plug it in to the amp as in the diagram in the post above? Someone told me there is a cable that plugs into the amp from the headunit that tells the amp to turn on......and well i wont be using a headunit.

    My system:
    Iriver mp3 player with line out
    6 channel amp
    door speakers
    6 by 9
    1 sub

    Will my amp be on all the time even when the car is not running and so flatten my battery?

    Many thanks!

    amps just need a 12 volt trigger, if you want you can just wire the blue wire to a yellow wire on a molex connector on your computer

    well everything in ur fuse box will have 12 volt

    you need 12 volt that turns on when u turn ur car on that way ur amps are only on when ur cars on and it wont drain your battery

    usualy ur wipers - power windows - radio are only on when ur car is on try to ind ur wiper fuse and tap into that
