It definately wasn't abused. the guy before me bought it for HT use and never used it. I use it sealed in an sq application. I'm running it at 4 ohms currently as my 750.1 doesn't like the 1 ohm impedance in hot weather. It is in mint condition, no scratches, rub marks, anything.anything wrong with this sub? was it abused? [aka 800rms daily]what year is it?
