babyjoker Posted May 7, 2007 Report Share Posted May 7, 2007 ok so my sis was complaning that her subs kept turning off, so i took a look and in one of the subs (2 12''s) u can hear what sounds like the voicecoil is loose or something, but still works up until i turned it up, then the amp goes into protection. I have heard this noice before on a DVC sub when only one of them is connected but these are SVC. u guys have any clue at what it could be?

Chris Posted May 7, 2007 Report Share Posted May 7, 2007 (edited) Sub Is Blown. x2. Whats probably occurring is that the glue holding the VC together is loosening up & probably a couple strands have come unattached. Now when the sub moves just enough, they rub on the basket underneath the spider & cause a short in the one woofer. This causes an overall resistance drop in the load on the amp, therefore sending it into protect mode. New subs are needed.
