Coils will still look brand new, after being smelly for months. Resistance would also be ok.
I'm just saying to the OP, that smell is probably nothing to worry about. If you've ever smelt a hard clipped sub, then compared it to the DC smell, they are different.
The good o smell of glue. I have my level 6 with a D9, boxed tuned to 29hz and was smelling as first. But the. It doesn't smell anymore when I bump for like an hour. ONLY time it will start stinky is with a clipped song or anything above 38hz+
