Just got some new fosgate 10'' subs installed with a polk amplifier. When I got everything plugged in, everything worked good and the subs put out great sound. Drove the car to walmart and parked it. When I came back, my deck wouldn't turn on. Drove it home and tried to figure it out. Checked the fuse in my dashboard, amp, and inline to the battery. All of them are fine. But then I noticed my lights wont flip down and my power locks don't work. Short? I don't know where to look.

 

a 10 foot speaker is real big like the 1 in Back to the future. Kidding

 

check the acc fuse it runs the constant 12 volt to the radio as well as the power locks and cig lighter

 

Figured out my problem. Had a screw fall into my cigarette lighter. I don't smoke so I didn't notice it. Screw shorted out almost every fuse in the panel XD. Thanks for the help!

 

Don't feel alone - I've done that too! Funny how those things drop right into the wrong places. At least it is easy to fix.
