I need to replace my passenger side dashboard speaker in my 99 Chevy Blazer.?

Question

However, there is a plastic k**b looking thing protruding through the speaker vent. I took off the vent and it is connected to a wire, but the speaker on the driver side does not have this. Can anyone tell me what this is before I go about replacing the speaker? I also can't find the specs on what kind of speaker it is or what size....I have the Bose sound system Thanks in advance for the help.

Answer 1

That's the light sensor for your vehicle's automatic headlights.  It's not part of the speaker system.  You can ignore it.

Usually the dash speaker in a Blazer is a factory tweeter in a 4x6 adapter plate.   If you're keeping the stock radio and the rest of the Bose speakers, your best option is to obtain a factory replacement for your blown speaker, rather than try to make an after-market tweeter work.  Check with a GM dealer parts department.
