Earlier today i traded my SA-8 v.1 D4 and some cash for a Rockford Fosgate 15" T1 dual 4 ohm, seemed to work fine when the guy did a demo, free air, off his amp, played for a minute fine, didnt smell anything, didnt hear anything funny, was wired at 2 ohms, so both coils were hooked up. Now i get home about an hour ago and did a a test in some random 15" box i found in my shed, for literally 30 sec to see how it sounded in a sealed box, crappy btw, and i took it out and it smells like old/ burnt/ electronics, it works fine, both coils are working, i tested them differently, and together, its got good excursion, doesnt bind, surrounds are good, i can see the coil is shiny copper, not burnt as far as i can see, so whats the problem? is it burning up slowly? is it about to burn up? can i only see one of the coils? was it burnt up, and fixed, so the smell is just there? what wrong with it?
thanks
