When I bought my car it had a kenwood headunit and JL audio all the way around the car (installed at a garage) well yesterday morning the headunit just wouldnt turn on...I messed with it some when I got home and it worked for....2 mins then shut off...can anyone tell me whats going on? Im assuming its a loose wire or something but yeah and help would be great.

 

Sounds like a bad ground. If you have a test light, pull the deck and make sure your ground is good. Also check you Positive wires (one to the battery and one to ignition). Also check fuses (most likely one on the back of the radio as well as in the fuse panel). Hopefully that will fix it for you.

 

check fuses and all connections.
