Ok ive got my 6x9's hooked up to my rockford amp and was just wondering, ok on my HU the HPF(high pass filter) can be turned to . 60-80-100 or OFF. IF i have the HPF on my amp set to like 45 and my HPF OFF on my HU will it cut off below 45 or will it get the signal from my HU and give the speakers every frequecy. I dont wanna set it to 60 because its too high for me
