Speaker Crackling - Only When Moving

DAK · Post by **DAK** » 26 Jun 2012, 07:20

Hello...

I have a '98 V70xc, and the rear passenger door speaker started to crackle - but only on bumps and sharp turns. On level/smooth surfaces, it seems to be OK - except once it starts crackling....it keeps happening more often. (Car has the factory: Radio/CD/Tape - I don't think there's an amp or changer...)

I took off the door panel to access the speaker, turned on the radio (key position I)....for about a half an hour - nothing. I shook the car, pulled on the wiring harness from the door to the door pillar...etc - nothing. It would not make the noise.... But, as soon as I put everything back together and took it for a ride - the noise reappeared.

So....I may try switching rear door speakers to see if that's the problem. Or, if someone else may think it's the radio unit itself, or if there is some type of ground....anything, cuz it's annoying......

Thanks

........just an update... Forgot to mention that I did try to isolate the problem by using the balance/fade. Even when I changed the balance away from that speaker, the was still load and clear leading me to think there is a short someplace, or a ground issue?

What.......no takers on this? So here's an update.... I pulled the cover off of the door pillar to access the wiring to check for any breaks or shorting - nothing found. I pulled off the plastic covers to access the wire harness on the floor...nothing found. But, I did notice that if I shake the Front Passenger seat fairly vigorously, I can get this speaker, and only this speaker to produce the crackling/static sound. (It seems more frequent when the car is either running or the key is in the (II) position. With the key in the Accessory (I) position - I cannot reproduce this problem as often, or as well...)

So........any takers?

See if the AMP is there. Cracking usually means poor contact/connection due to corrosion (moisture, age, oxidation, loose wiring)

Thanks...there is no AMP under the front seat. I also looked to see if there were (AMP Wires/Connectors) in case the AMP option is a Plug in type. If there are the connectors for the AMP under this seat, even though the car doesn't have an AMP...can someone shot me a picture so I know what I'm looking for?
