For sale is a pair of Bose speakers. Fully tested.

These were found in premium early 00's Nissan / Infiniti (Maxima, I30, Pathfinder, G35, 350Z, etc). Check the part number if you're looking for an exact match for your Nissan / Infiniti. Otherwise, these tend to be more oftenly used for speaker build projects due to them being an inexpensive high quality speaker. As seen, these are very heavily built with true dust cap, large magnet, etc. 

Note final picture showing polarity diagram on the back of the magnet. Just a heads up to let you know the correct hook-up sequence for these...ignore factory wire colors, of course.
