Securing speakers

[Rambo2]

Hello,

I am fairly new to the site, so I hope I am doing this right. I have a 1970 GMC and am ready to start putting the stereo in (no dash cutting). I have the head unit ready to mount in the glovebox, 2 4" speaker pods in the back corners of the cab and the 2 6.5" kick panel speakers. I am wanting to replace the generic speakers that came with the kick panels with Kickers I have. The dimensions are all good, but the holes don't line up on the speaker and the enclosure for easy mounting. The plastic enclosure is very thing, and I fear it may crack if I try and drill new holes in it. Is it possible to seal the speaker to the enclosure with an adhesive? I don't want to comprise the sound or the structure so any car audio advice would be appreciated.

I'd say it depends on how much contact area there is between the speaker and enclosure. It may work you could try some silicone like "goop" or some two sided adhesive. You would probably be better off drilling new holes, if you warm the plastic up it will be less likely to crack you could also use a dremel with a grinding bit instead of a drill bit to avoid the issue all together.
