I am trying to install aftermarket front speakers in my 2002 Honda Civic EX.  I installed the right side speaker and turned on the head unit to make sure it was wired properly.  It seemed fine, so I closed up the door panel, etc., then turned it on again before starting on the left side.  Then I heard "pop," and now, no sound at all from front or rear.  I checked the fuse - its OK.  Every time I turn off the head unit, and then turn it back on, I get the "pop" from the new speaker and no sound at all from anywhere else.  Its just one "pop," then silence.

It is possible that I have the wrong polarity on the connection to the new speaker, because I could not tell from the original harness which was positive or negative, and I could not find a wiring diagram.  Would that have caused me to blow the voice coil or something, if the polarity was backwards?

having polarity backwards wont cause the voice coils to blow, it will only change the phase of the speakers. if the only thing you did was change the front right speaker and now its having problems, the logical step would be to remove the speaker and see if the system functions properly again. also double check to make sure that the terminals for the speaker are not shorting out on anything metal as this would cause the deck to shut down.

here are the wire colors taken from directechs:

LF Speaker +/-
RF Speaker +/-
LR Speaker +/-
RR Speaker +/-

Thanks.  I followed your suggestion - popped out the new speaker, and disconnected it.  Head unit played fine.  So I reconnected the new speaker and turned on head unit - played fine again.  I let it play for a bit without reinstalling the speaker in the door - played fine.  Only thing I can think of is that somehow (as you suggested) the terminals may be shorting when its installed.  They may be contacting the sheet metal, or the metal surface of the Dynamat I also installed.  I need to figure out how to insulate the terminals from the metal surfaces. 

Also, from the information you furnished, I think I actually had the polarity correct.  But its good to know that wouldn't have burned out the coil.

Thanks you very much for your prompt and knowledgeable reply!
