GM 6X9'* not standard mount?
I'm trying to replace the 6X9 "subwoofers" (9 speaker system) in the rear deck of my 99 Park Ave with coaxials for rear fill. The factory amp is gone and I will be running them from the rear channels of my HU.
I've tried two brands, CDT and Boston Acoustics, and the speaker mounting holes just won't line up with the holes in the plastic package tray. Are the GM 6X9s different than the standard mounting centers? Has anyone successfully installed aftermarket speakers in the rear deck from underneath? If so, what brand did you use?
And now I've broken those silly plastic retainer clips, p/n 25641031, which I can't find anywhere except from GM for $4 each. Grrr. Anybody know of a source?
