Hey guys i just bought a crossfire vr4000d off of craigslist about 2 days ago, unfortunately i should have tested it before buying it. So i hooked it up today to my to 2 12s, dual 2, at 2 ohms but as soon as i started the car, the amp turned on and started to go in and out of protect mode. Basically the power light would flash, then the protect mode light would flash, and keep on going back and fourth. Along with that the interior lights of my car started dimming then getting brighter then dim again. The amp wasn't producing any power so the subs were not playing but the amp did get hot. Any one know what could be wrong?
