I just had my bose amps/speakers rebuilt on my 90Q For some reason they sent and extra brand new speaker/amp enclosure for the rear.
Here's the kicker--- it's for an Acura Legend...I think 88-90 model...it looks the same as the Q's except for the end plug.
I am looking to sell it for a reasonable price... I don't think Bose rebuilds these...everything looks brand new.
