i have a crossfire vr2000d, i ran it at .7 ohm daliy on my 2 q 15's for about 4 months, i dont know if thats why its now blown or not, it seemed to hold up fine until it blew, no protect lights or overheating.
anymore taking the xfire and md seriously the pa is also nice but if off brand i need two.so what im saying is i think a good off brand but has to be 2,and brands 1 strong insane amp
well after i get it fixed i was gonna sell it for 350 shipped but for joo ill let it go for 300. or if you would rather buy it without being fixed then make me an offer
