1. window gets wayyyy to hot, i need to get it professionally tinted
2. down in my trunk is probably the coolest part of my car

you'd probably shatter it if you seriously did that either way lol.

i'd screw up amps if anything
car gets so hot my rear view mirror won't stay on (combination from the heat and vibrations)
my front speakers were so hot the glue was beginning to separate from the metal frame

i meant if you super glued something as hard as metal onto something like glass it would probably end up shattering the glass since glass is more flexible than the metal.

hook up some 12 volt computer fans if you're worried about heat.

leave your windows cracked?

get rain window guards that way you can crack windows without anyone knowing they are cracked.
