[QUOTE="mat3833, post: 7930925, member: 587645"] ok, im going out on a REALLLLLY long and REALLLLLY thin branch here, but i can say i actually experianced something similar to this. i pulled some 6.5" subs from an old 2.1 computer system a few years ago. rated RMS was 50W each(labled on the bottom of the VC), but they were only seeing ~25W each from the 2.1 amp. so i built 2 boxes smaller than their factory enclosure(factory enclosure was 1.4cubes internal volume not taking into account driver displacment, the enclosures i built were .6 cubes external volume with .5" MDF again, not taking into account driver displacment). now i threw both of them in my trunk and wired them to 2 ohms. set the gains on the TMA 500.1 i had at the time to deliver 80W to the pair. after 30 min of driving to work, one sub popped. and on the way home the second popped. now i never actually looked into what happened, but the coil was visibly charred. and the TMA 500.1 is rated at 500W @2 ohms. gain was virtually at minimum and it was a clean signal. BUT in the real world, running a sub at less than its RMS for a month, year, or even a decade, and then putting more power to it will cause no harm at all. Matt [/QUOTE]
