All of a sudden about 3 days ago my speakers in my car dont play just my subs. At first it was only happening at night and I couldn't figure out why for the hell of me. I so pull the lower din and just wiggle the wires and it works np and this has happened several times. I was showing my friend today what happened and I realized it ONLY happens as soon as I turn on my lights on. Other than that it works fine thus why it doesn't work at night??

Next day: Ground is good, wires appear fine. It just damn does it when the lights turn on then if i turn the car back on wiggle the wires in the back of hte deck it workds np. Then I turn on my lights then again!
