Alright I have some JL XR650-CSi's in my car, and just recently one of the woofers have been acting up. I tested the leads with a DMM and the resistance showed 3.2-3.3 ... it's a 4.0ohm speaker. The speaker plays perfectly until I play heavy bass songs, and then it makes some really annoying cracking sound, sort of like a rattle. The gains have been set right because the amp hasn't been touched in 3 months and I haven't had any problems. Does a blown speaker have no continuity and therefore no resistance reading, or how do you determine if the VC is still intact?
