i have 2 Hifonics Olympus OLM1612 only used about 2 mnths. still in good shape. One of them has a scratch on the cone that peeled up a little bit of the paper. but does note effect performance at all! pm me if insterested.
people including myself give them 1200w all day with no problems. i had bought 2 and only used one. the other one is pretty much new. just mounted and tested off low power to make sure it worked.
i'll part with just one lol...they can take 1600 watts rms, i had almost a 1k on each and they did lower 140's sealed at the dash in an 05 altima in a prefab.
