Replacing my quarter caps because split and mounting plastic cracked. As you can see, passenger side has a speaker and driver side does not. Both sides have a connection for a speaker. First thought driver's side had been replaced with a non-speaker cap. Then looked at a salvage XK8 at CoPart thinking of picking up as a parts car. That car has the same speaker on passenger and not on driver. Finally, I looked for what is for sale on eBay. For passenger side plenty of speaker/non-speaker choices. For driver side, only non-speaker. Is there such a thing as a driver side cap with a speaker or is that connector just not used?

 

Think I answered my own question. One of the parts sellers on eBay on their parts puts a sticker that lists the brand, model, year and VIN. They have a no speaker driver side and speaker passenger side with the same VIN.

 

That is not a 'speaker' but is a transducer as part of the SRS.

 

Got it. I was wondering why four wires because thought little small to have two speakers. So I guess it tells car if someone is in passenger seat and that's why plug on both sides.

 

yes, if you unplug it and power on the car you will get an airbag warning light
