Anybody else have the same problem with passenger side front door speakers?

Ive own the truck since 2003 and every 2 years or so, the passenger side front door speakers will stop working. doesnt matter what i put in there, Rockfords, Infinity's, etc. My best guess is that water is getting to them some how but they usually dont look bad when i pull them out. Sometimes ill be driving and they'll quit for a couple of minutes then ill hit a bump and they come back. ive checked all connections and usually i can get it to do it by fussing with the speaker itself. A new one always solves the problem for a year or two.

It definitely sounds like a connection or grounded wire somewhere. If all else fails you can always run new wire from the radio to the speaker. Are you soldering your connections? or using the junk crimp connectors? if you are using anything besides solder, that could be your problem. It could also be corroded wire (I've seen it in about 80% of the vehicles I have put speakers in)

Yep fixed it last week, was crimps in the door

+1 for solder!!!
