Never tried it before. popping a new 15' in my 15' cab. the one i have now,,, i mean,, it can't be,,, but it looks like someone ripped the center out with a knife(the dust cap, or whatever it is) and put a voice coil behind it?!?!? It sure does sound like it's picking up alot of fingernoise, so i'm GUESSING it has a some high end thign in it. my question is, HOW DO I POP IN A NEW 15'?Just take that one out, pop in the new on the same as the old one?
