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.
Iriver mp3 player with line out
6 channel amp
6 by 9
Will my amp be on all the time even when the car is not running and so flatten my battery?
