Door Speaker Problems

in my passenger door when i roll window down all the way, ill randomly hear like a buzzing noise at times, then i can roll it up/back down, or hit a bump and itll stop, or sometimes does it when i open the door, but then also when i set the balance to all passenger side, i can notice that the 5x7 and tweeter are both very faint, barely hear anything from them. figured itd be a slimmer chance BOTH are blown, they seem to be nice JL 5x7s and Kicker tweeters, sound great in the other door.. any suggestions on what to check? would pinched wire do that? I could do away with the factory wire and run a new one direct from the harness through the jamb into the door maybe.

also, do replacement rear speakers fit right in? i know the doors have adapters.. but my rears are factory speakers still..

 

the rear doors need adapters also

 

I would start by looking for a loose speaker wire on back of the speaker. Then, if you are using an amp check for a loose speaker wire on the amp. Then, check for a loose RCA cable at the amp.
