Summary: Whenever I slam the front passenger door closed, the speaker will stop working or start working depending on its pre-slammed condition.

What would cause this? More details below:

I bought the truck and both the front speakers didn't work. I pulled off the door panels and saw that the guy installed Rockford Fosgate speakers- but the terminals were corroded so bad that the speaker wires became dislodged.

So I bought some cheap Wal-mart speakers and replaced both sides, I also upgraded to a 4 channel amp- so the speakers are all now powered by this amp.

Soon after the install, the passenger side front door speaker started cutting in/out whenever I would hit a bump, or when I closed it. Soon it started crackling and I figured it was the "you get what you pay for" scenario.

I just now upgraded to $250 Pioneer speakers for the front. I just got done installing them, and to make sure the problem was gone, I slammed the passenger side door.... and the speaker cut out. I checked the speaker wire going to that speaker, and it LOOKS ok. I mashed it and pinched it to try to see if it is a bad speaker wire (all parts from the speaker, door jam, going to the amp), but it kept playing fine until I would slam the door (I haven't driven it yet to see if it does it over bumps, but I'm sure it will cut out over bumps).

I'm at a loss.. Anything you guys suggest I check?

 

Loose connection , ???

 

I checked/pulled on violently the connection at the speaker and amp, all looks good lol

 

Wire might be cut some where. Do a continuity test on it. You know what that is correct ?

 

Yes I know what a continuity test is (IDK if you are trying to make fun of me or not)

I'll try that though, thanks.

 

did you check the connection in the door hinge area inside the rubber tube. see them fail alot on dodge trucks

 

No wasn't trying to poke fun, a serious question, alot of people do not know what it is.

 

I have repaired broken wires before in the door jamb area. Its more common than you think. Do a continuity test and have a helper open and close the door while testing that wire. Wiggle the door jamb wire boot also. If you lose continuity at any time, run a new speaker wire.

 

if the continuity test doesn't show anything swap the speakers and see if the problem persists on the same side or changes with the speakers. I just had a similar issue on a clients avalanche, and it ended up being the speaker itself.

 

Hey guys, it turns out it was the brand new cd deck I had installed when I installed the speakers...

The detachable face on it is broken, something internal. If I push in the face at the top left corner slightly, the front right speaker cuts out.
