Did this for a friend he wanted 1 - 8" mid 1 - 10" mid and 2 - tweeters in his door, so i cut out a mdf base to match the door panel, trimmed to fit. So here's the mockup so far, it all fits snug, we're using all crescendo components the selenium is for mockup. Using regular fleece and two coats of resin no fiberglass Fleece stretched and stapled Two coats of resin Fitted to the door Finished product nice and snug Not as smooth as i could get it but my friend didn't care otherwise i would have bondoed it, i think later down the road it will get vinyl not sure though
