[QUOTE="Jeffdachef, post: 8631798, member: 650438"] I actually cant, its just something I see happen from my buddy's setup where they tend to clip the setup(despite my warnings and clear instructions not to) a lot and a year they said the sub isn't anywhere near as loud as it once was. Coils look a bit darker, Checked the impedance, it went from 1.8 ohms on both coils when I first installed it to 2.4 ohms on one coil and 2.3 on the other. Reading is the same through several different multi-meters and there was no resistance on my multi-meter. The sub died out a few months later with only one coil working reading 5.2 ohms. I would guess the copper is not as conductive when its at the point where its burning out hence you get higher resistance? I'd probably need to read up on it or if you can explain that'd be swell too. [/QUOTE]
