[QUOTE="Wingman0121, post: 6770974, member: 620554"] The smell of burning coil does linger around in the box and within the subwoofer though, so you can do this... take the sub out of the box with it still hooked up and see if the cone moves either in our out when you first turn your stereo on, if it moves without any music playing then it is getting DC from the amp, if that's the case then either the amp is faulty or your headunit's preamp stage is faulty, or the RCA cables are pinched and grounding out somewhere. If it doesn't move then play some music and observe the sub's movement and see if anything erratic shows up. It ***** because it is much harder to troubleshoot car audio systems especially if it's something strange. [/QUOTE]
