I just discovered my 89 vert has rear speakers that must have been disconnected by the previous owner.Anyway,I went to the Crutchfield site and it indicated 5X7's were the right fit.I peeled back the rear panel enough to see that they are round,maybe 6.5's or 5.25's.They do not look anything like after market speakers so they must be stock.Any other Vert owners who changed out these speakers who can help me determine what was stock and what will fit with aftermarket speakers?Also,the location (behind a panel) is crappy for producing sound so will any speaker sound decent in there?I currently have 5.25" Alpine R components in the front and a sub in the trunk.Thanks.
