Checking power to speaker
 

Im trying to figure out if i have power going to my passenger side door speaker, whats the best way to do this and if it is bad how hard would it be to replace the wire........and also i have an aftermarket head unit

take off your door panel and connect a different speakers.

Do you still have the speakers in there? Couldn't you adjust the balance to the right side and listen? I've only been running with the left side drivers door since my passenger speaker has been blown to smithereens.
Or am I missing something?

well the speaker use to work for a while then it would just quit for a while, for days or weeks and then it would just come on again......i have another speaker but its a used one but i got nothing out of either........how hard is it to run new wires?
