My nephew wants me to help him put his amp and speakers into his 89 chevy s10. I've done speaker work and amp work before, but he is asking something new of me. He wants to put the speakers in his door (which of course isn't straight forward because of the window). I don't really want to make a big gangly wood enclosure, and looking around the web I notice all kinds of custom dashes, door panels...all sorts of really neat stuff. How do they do that???? Is there a place you can go and say "this is what I want," or do they just know so much that they somehow mold plastic themselves to fit what they want??? I would really really like to make my nephews truck the hottest in this one horse town, if anyone has any ideas I would appreciate it!!
