lots of options...depends on if you want GOOD sound or
something that looks factory
if you can mount 'em on the a-pillar and bounce the sound
off the windshield thats probably best...another option is
the plastic (black) mirror bolt covers on the front doors...
otherwise your looking at mounting 'em in the doors... (front
and rear...something like ive done).
if i had to do it over id have tried to work my front tweeters into
the black plastic that covers the mirror bolts...
you can also mount 'em in the rear most plastic high in the corners
(i also have a pair there)...so yeah i have 3 pair of 6.5" seps in
my truck.
