I have a 2000w 12 inch orian sub a bridged 2000w 2 Chanel amp with a 2600w wiring kit and a 1.5 power cap. My problem is I have the bass on my head unit at -7 the loud off and treble at +5 my gain and frequency is at half way and when I turn the power on my sub thuds and then my amp kicks to protect mode. I turn off the power turn gain and frequency all the way down turn power back on then I can turn them back up but I can only turn the volume up to about 30 and my amp kicks back to protect mode and the process repeats. I am at a lose as what to do I tried taking out the 20 amp fuses from my amp and put in 30's I was able turn the loud on at the same volume but the same thing happened once I tried turn the volume up. Please help!!!
