toyota camry install

I was doing well untill I came onto the rear 6x9s.  I took out the rear deck, and the factory speakers only had 3 screws attaching them, and the pioneers which best buy said should fit in there, don't really drop into the hole.  its up against the rear window, so its even harder to drill holes and attach screws.  If anyone has any advice on this, it would be great.--Kosko--

The magnet has plenty of room, it is the contour of the metal that is not the same.  The three hole pattern does not line up at all.--Kosko--

mount the new speakers from inside the drunk, meaning instead of mounting the speakers from the top mount them from underneat the reardeck, put the speakers againt the rear holes and drive 4 screws from the bottom, hope this hepls   good luck   steveA man has got to know his limitations

I might just have to do that, that will allow me much more room to install the rear deck anyway, since I am going for the factory look (it's not my own car).  Thanks a lot, I appreciate the help, but If anyone else has a suggestion, that would be useful as well.--Kosko--

I finished the install today.  I drilled holes easily using the supplied template, and I dropped bolts through the holes and mounted the speakers underneath with nuts.  It sounds awesome.  I  put the pioneer 4ways in the back and 3way 6.5s in the front.  They are powered by a 4ch Alpine amp, and I have one 12" Bazooka sub powered by a 2 channel amp bridged.  I am running them with a pioneer DEH-P3500.  Quality tunes.  Thanks a lot for all of your help.--Kosko--
