this is what you do mr starky,
you cut a ring out thats got the right inner dimension as your speaker, and 1" larger OUTER dimension as your speaker [or the grille] . then cut ANOTHER rig, thats like 1\8" larger than the outer dimension of your speaker [again the grille], and 1" larger than the outer dimension [yet again, the grille]. stack them up, glue them together, and your speaker should sit flush with the grille in there.
then make a rear mould of glass, IMO - only 2 or 3 layers is needed. then use chopsticks (cheap+free @ local resturant) and hot-glue to mount them in the right direction (try to aim them a little in front\below the opposite headrest if you can)
then get some fleece, and after you cut and sand them rear moulds with the baffles on there, stretch it over the entire thing and hot glue it down on the back of the mould.
resin it up, let it dry. cut the center out with a dremel, then resin the entire inside. let that dry, and then get some adhesive spray, and cover the carpet and the pod. let it tak up for a minute or so, then stick it on (all the way into the baffle if you can) and use a razor to cut out the center.
if you do it like that, they should come out really sweet, but never make your baffles all odd shaped like you did with this expierement. and try to mount them higher up into the corner (or attach them to your stock kick panels //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif )
props for trying this tho - lots of people just spend money on q-logics //content.invisioncic.com/y282845/emoticons/tongue.gif.6130eb82179565f6db8d26d6001dcd24.gif
good job, but you still need a little more practice //content.invisioncic.com/y282845/emoticons/thumbsup.gif.3287b36ca96645a13a43aff531f37f02.gif
