Buzzy/staticy car speaker
ChadTower:
I have one speaker in my car that's all buzzy... not all the time, but any time it tries to pull any real amps. It's a 6x9 regular car style speaker, decent but nothing that would be under powered. Head unit is a recent Blaupunkt, can't recall the model #, but it plays mp3 to give an idea of age.
When I installed it a few years ago I didn't know how to solder, so I had just twisted the pairs and covered them with electrical tape. I just uncovered them all and gave them clean solder connections, no difference.
The wire connections on the speaker are clean solder joints.
I'm pretty sure it's not the speaker, but just in case, I do have a couple other spares I can swap in to be sure. I'll try that over the weekend.
If it's not the speaker, and we can assume it's not where I had to splice the car system to head unit harness, what else could I try? The pins in each end of the harness for that speaker look reasonable, not burned or bent or anything.
The only other two things I could think of would be that the head unit developed a problem on that line or maybe somehow the speaker wire has developed a short between the car end of the harness and the speaker... does that actually happen?
psik0tik:
It can be a few things...it can be a short from stereo to speaker or it could be a channel on your stereo going bad. I would deff try to swap the speaker first it may just be a dying coil in the speaker :) also if you have an amp try a diff set of rca cables on it.
ChadTower:
No amp on this one, just straight head to speaker. The other rear 6x9 works just fine, same setup. How would a short develop from stereo to speaker? A pinched wire somehow?
psik0tik:
More like vibrations in daily driving rubbing a wire against the body somewhere till the insulation wore off..it's happened to me before.
ChadTower:
Good thought. If swapping the speaker doesn't do it, I'll trace the wire. I have no idea what route it's taking. It's a Civic, if that helps.
