hello there,
I just installed a pair of 6.5 alpine sps170a's in the front doors of
my 97 civic. I did this myself, I have little experience, and I had a
few problems I hope someone can help me with.
the speakers definitely stick up and out a little, even though i tried
cutting out some of the plastic in the speaker wells. this creates 2
problems; 1) I don't have a proper sound seal since there is a 1/4
inch gap all around and 2) the old speaker covers (that snap on) still
snap on, but since the speakers are sticking up high, the covers
aren't quite seating in the way they should, esp. towards the front of
the door.
so for the gap problem: can you advise this relative beginner, do I
need some MDF? is that medium density fiberboard?? where can i get
it, and how does one cut it to size, etc., etc., or should I take it
to an installer?
and what to do about the speaker covers not quite seating down in
where they should? just leave it, or is there a fix? any advice
would be MUCH appreciated!

If you're a little off, use a heat gun to stretch out the splash guard
so the speakers seat properly.
If you require serious modification:
o Remove the door panel.
o Cut out the basket.
o Drill hundreds of 1/16 inch holes in the plastic. Use a high density
of holes near the mount and reduce the density with increasing distance.
No adhesive will bond to the plastic but these holes create very strong
rivets.
o Build a new mount and splash guard using fiberglass or carbon fiber.
An old speaker wrapped in duct tape can be used as a mold.
o Chisel or grind away excess epoxy that has leaked through the holes.
o Grind the mount to proper form. Drill speaker mounting holes and cut
threads.
o Apply a thin surface coating of epoxy over the exposed fibers.
o Enlarge the opening in the metal door frame with a "nibbler" or "angle
cutter." Coat the edges with a few layers of rust-proofing paint.
o Attach door and install speakers.

well thanks for all that advice! but I'm afraid it was technically
beyond me . . AND i discovered that if you use the enclosed plastic
disks from alpine (after breaking off the outer tabs) you can
essentially "build out" the size of the door enclosure (about 1/4
inch) to accomodate the speakers. was important of course to get a
good tight seal . . . and the way the speakers stick out with this
install it was just better to remove the old honda door speaker covers
and install the alpine speaker covers instead.
alpine could provide a better set of instructions than what they
include, but their phone support was very good. --fj
