I just recently started having sound problems with my components in my passenger door. It started yesterday with crackling and then the sound going in and out. Pulled the door apart and noticed if I put a little pressure on the cone I would get sound, and sounds fine. I've not had any problems with distortion or anything before hand. I'm running CDT's, M6 for mid bass powered from and ED nine.5.
The only thing I can think of is the voice coil has damage. Just looking for any ideas.
