So my battery went bad the other day and my truck wouldn't start so we tried jumping it from a Dodge RAM which still didn't work so we hooked it up to an industrial quick battery charger. Bad idea, smoke came out from my cab, not much but you could definitely see it coming from the dash. Eventually I bought a new battery and my truck started right up. The high voltage blew out both my front head lights and now I have bad static every time the base hits or if I have the volume turned up past 20.
If I adjust the balance however to only one side, the speakers on that side of the truck work fine no matter how loud. This applies to both sides.
Is this a bad head unit or something with the speakers, how much does a new head unit normally run?
