Problem installing kenwood ddx714

[david712370]

Alright guys.... i really have no idea why i am having this problem and perhaps there is an easy explanation. But today when i went to install my head unit i was i could not get my unit to power up. So eventually I tested the wires and concluded that I am not getting power to the unit from the red wire, from the harness. When i connect the red wire to yellow one it turns on and powers up normally. So from what I can tell is that the red wire is not getting power when i turn on the car. Has anyone heard of this problem before? The other thing I noticed is that the power wire for the amp does not get power either, I am guessing this is related to the red wire going into the unit not getting power...Any suggestions would be appreciated very much....
