I'd just replace them with some new no-name brand speakers, rather than use 10 year old stock ones. They are a standard size, you should be able to get cheap ones from any car audio place without a problem.
Thanks, you are right. $20 Pioneer speakers from Best Buy and they are still better than what was in there before. A $5 Metra Kit (Part # DW7901SH) and 5 min later both rear speakers are installed. These things were a direct fit and no problems at all. For $25 they sound great.
When you mean "pioneer speakers" (not referring to the ones you just bought), do you mean factory pioneer speakers? THat's wierd, I never knew our cars came factory with those. Then again, when we pulled the rear speakers from my friend's '89 mx-6, they were much nicer looking than your average stock speaker, 2 way coaxial and everthing. The rear speakers on my 626 were nasty and crappy looking.
When you get the METRA speaker connector kit you don't even have to worry about polarity since they connectors are keyed and so are all the newer speakers. The plugs will only fit one way on the speaker end and when it is re-attached to the car.
As for the "Pioneer" Speakers, both the head unit and the speakers themselves on this 92 MX6 have "Pioneer" stanped on them. I am sure that they came this way from the factory. This unit is the CD cassette unit.
The original stock "Pioneer" speaker that I pulled out was foam ringed and this is what was messed up. In the junkyards I found a few other 90-91's (never another 92) and they were foam ringed but never said pioneer. They did look like the same speaker though. All were messed up like the ones I had on the 92. On the other hand, I found a lot of 88-89's and they all looked 2 way and all were in great shape. The down side was that they would not fit properly into the 92 because the speaker cover would not fit over them properly.
